It’s No secret — I Love Medify Air Purifiers


I’ve been researching air purifiers for quite some time now. And I sure have come across many great options.

But I can say without fear of contradiction that Medify offers some of the best air purifiers on Earth.

It’s easy to get carried away while describing a product you love. But I always strive to communicate objectively. You won’t find salesy content here. If while writing Medify air purifier reviews I find a downright-crappy device, I’ll let you know.

Yes, I’m a marketer. And I’ll earn a small commission if you end up buying any of these air purifiers. But I’m a decent chap who never calls white objects black and vice-versa.

Believe it or not, I’ve seen some of my readers buying products whose cons outnumbered the pros! Why did that happen? It’s because they felt I was honest and straightforward about the opinions I offer here.

If you ever feel I’m just trying to push products rather than trying to be helpful, call me out. Shame me, and make sure to tell others about this website and my glaring dishonesty. A shameless, slimy salesperson deserves no better than that.


Medify Air, the Manufacturer Behind Medify Air Purifiers


What do MGM Grand, The Redbury, Resorts Casino Hotel, Trump International Hotel, Sheraton Grand, Marriot, and Hilton have in common? They all love Medify air purifying devices.

I’m not saying buy Medify just because big-name companies buy them, though. I’m simply saying that many credible brands think Medify air cleaning devices are great.

They don’t buy these machines because they’re cute (they are by the way). They favor them because they work.

But why should you trust Medify Air? They’re not the only great air purifier manufacturer in the world. So, what makes them stand out?

Medify was established in 2017, and that makes it almost a new company. But the people behind it are seasoned engineers and finance experts that understand how to make a business work. Together, they bring to the table a combined experience spanning over 50 years.

Medify Air has been tinkering with air filtration technology developing it, testing it, improving it, and fine-tuning it. As a result, the air cleaning devices they make are some of the best on the market. I mean, how many air purifiers purify the air down to 0.1 microns? Very few indeed.

Do you know why you should choose an air purifier that filters the air down to 0.1 microns? It’s because you want to live long. You don’t want to be among the over 8,000,000 people dying each year due to air pollution. Let that sink in. Over 8 million people lose their lives to air pollution (both indoor and outdoor air pollution) every year!


Two major kinds of air pollution are:


  1. Indoor air pollution


  1. Outdoor air pollution (also called ambient air pollution)


Air pollution refers to a whole spectrum of very small particles that when inhaled can cause dire complications. These particles are classified into two types: PM2.5 and PM10.

PM means particulate matter. PM2.5 refers to all particles whose diameter is smaller than 2.5 microns. One micron is a very small unit of measurement. It equals about 0.00004 inches. By contrast, PM10 are particles with diameter ranging between 2.5 and 10 microns.

Your eyes can’t detect anything smaller than 50 microns. And the diameter of your hair is roughly 80-100 microns. Most PM10 and PM2.5 particles are microscopic — you’d need a powerful electron microscope to see them.

The EPA calls PM10 inhalable particles while referring to PM2.5 as fine inhalable particles.The naked eye can detect some PM10 particles either because they’re large or are quite dark.

While both PM2.5 and PM10 are lethal, PM2.5 are terrifying because they’re extremely small. For that reason, PM2.5 can travel to the remotest cells in the body and cause havoc there.

Most True HEPA air purifiers remove both PM10 and PM2.5. If you visit Amazon now, you’ll see that most of these devices handle particles 0.3 microns in diameter or larger. But as noted above, you should worry more about 0.1 particles than 0.3 micron particles. Generally, the smaller the particle, the more potentially harmful.

All Medify air purifiers help eradicate particles as small as 0.1 microns. They can filter out face powder particles whose diameter ranges from 0.1 – 30 microns. They also can effectively filter out paint pigments, household dust, mold, bacteria, viruses, and pollen. In addition, they can easily eliminate particles coming from burning wood, tobacco smoke, pet dander, skin flakes, and asbestos. That’s the Medify difference or advantage.

11 Reasons to Buy Medify Air Purifiers


Let’s jump right in.


1. Lifetime Warranty


Medify Air is probably the only manufacturer that provides a lifetime guarantee for all their products. As long as you replace filters when you should, they’ll fix your unit or replace it.

Now, compare Medify’s lifetime warranty with 1-2 year warranties typically provided by many brands. See, buying a Medify offers complete peace-of-mind. They surely must have absolute confidence in their products. Think about it again — ALL Medify air purifiers come with a lifetime warranty.


2. Some Medifys Are CARB-rated


Renters and homeowners in California can use some Medifys because they’re CARB-certified. They’re safe to use in this state. California doesn’t allow air purifiers producing over 0.05 ppm of ozone to be sold within the state. So, with the CARB-rated options, you and your loved ones have nothing to worry about.

While researching for this article, I discovered that out of 6 purifiers made by Medify Air, only 3 are CARB-approved. Read more about CARB certification here.

The Medify MA-14, MA-40, and MA-112 are CARB-tested and approved. But the MA-440, MA-18 and MA-Smart aren’t CARB-certified as of this writing. I’ll update this section if and when any new developments happen.


3. Some Are AHAM-certified


AHAM is a private organization that performs a series of tests on air purifiers to rate them.  Manufacturers aren’t required to have their air purifiers tested by AHAM, though. It’s AHAM that provides the CADR info you see on most air purifiers.

But why is CADR info important? Why should you care? There’s a lot of confusion surrounding this number. But what is it, and what does it exactly measure?

CADR is an abbreviation for Clean Air Delivery Rate. It’s a universally accepted language of describing an air purifier’s efficiency. It gives an indication of how fast or slow a purifier is.

AHAM tests air purifiers and comes up with 3 critical CADR numbers for every machine. It bases the ratings on each machine’s effectiveness in terms of handling 3 common particles. These are smoke, dust, and pollen.

The CADR for smoke represents how well a particular type of air purifier removes 0.09- 1-micron smoke particles. Similarly, the CADR for dust showcases the device’s effectiveness in handing dust particles in the 0.5-3 micron range. Finally, we have the CADR for pollen. The number expresses the purifier’s effectiveness in terms of eliminating pollen particles ranging between 5 and 11 microns in diameter.

Two factors come into play when calculating a CADR rating. These are the air purifier’s air flow and filter efficiency. CADR numbers indicate how much sanitized air a device delivers when running on the highest speed. If you run your device on a lower fan speed, you’ll have a lower CADR than what the unit is rated for. Keep that in mind when shopping.

I advise my readers to always buy an air purifier with a greater CADR than they need. Why? It’s because no one runs their air purifier on high the whole time. But everyone wants their machine to work effectively even on low.

Many people in the United States today battle allergies and asthma. Breathing in these allergen triggers makes their life miserable. Luckily, portable room air cleaners have been scientifically proven to help with allergies and asthma. Read more about whether air purifiers offer any relief for allergy and asthma sufferers.

The 3 CADR numbers mentioned above provide a reliable way to compare different air purifiers. If you’re looking at two AHAM-rated air purifiers, always take the one with a higher number. All other things being equal, that device should perform better than its competitor in terms of purifying your air. You’re advised to always pick products whose CADR value is over 100 — the higher the better.

Additionally, this number helps you to estimate the amount of room a given air purifier can effectively clean. If you multiply the CADR number by 2/3, you should get the room size the machine is built for. For instance, a device with a CADR of 330 is designed to treat rooms measuring about 220 square feet.

In the U.S., CADR is expressed as CFM, which means Cubic Feet Per Minute. In Asia and Europe, however, CADR is expressed as CMH, Cubic Meters Per Hour.

I CFM =1.699011 cubic meter per hour.

So, what’s the relationship between CADR and CFM? I’ll answer that. Assume a particular air purifier moves 100 cubic feet of air every 60 minutes (CFM of 100), and its filter efficiency is 80%. This machine’s CADR should be 80. As you can clearly see, CADR is a product of efficiency and airflow. That is, (80/100 x 100).

Good news: ALL Medify air purifiers offer CADR numbers. You can easily compare them with other purifiers and see how they stack up. The Medify MA-40, for example, offers a CADR of 330.

In the promised Medify air purifier reviews, I’ll tell you everything about these air cleaners. I’ll lay bare both the good and the bad. And I never omit ugly things about a purifier if I encounter them.

If I tell you an air purifier works, rest assured it does. Similarly, if I point out that a certain air purifier doesn’t make the grade, don’t buy it. If you do, you’ll almost always rue your decision.


4. Medifys Look Great


Let’s admit it — most air purifiers aren’t cute. I’d even say that the air purifier market today has more than its fair share of ugly products.

So, what do I think about Medify air purifiers? Well, I can’t say they’re the cutest air cleaners I’ve seen. But they look every inch like the sleek, modern devices they are. And because these machines are mostly black or white, they plug nicely into the existing color scheme.


5. They Effectively Remove Both PM2.5 and PM10


With Medify air purifiers, you’ll worry less about asbestos, tobacco smoke, VOCs, construction dust, and more. Also, household dust, pet dander, pollen, and other allergens will have to look for a new home.

If allergies and asthma bothered you, consider buying a Medify. Of course, they won’t cure your allergies or asthma, but you’ll start enjoying your life. You’ll start sleeping much better, and all the sniffling will soon be history. You’ll start looking forward to spring with all the beauty, newness, and hope it brings.

And does your home stand near a busy road? If yes, your air possibly contains loads of benzene and nitrogen dioxides. These pollutants are potentially dangerous. You need the best air purifier for exhaust fumes to handle them.


6. They’re Easy to Use


You don’t need to know much about air purifiers to use Medifys. Simply get your device out of the box and plug it in. The filters come pre-installed. Simply plug them in, turn them on, choose your preferred speed and voila! clean, crisp air.

With most air purifiers, you have to fit the filters in correctly before you can use your machine. And if you insert the filters wrongly, the unit likely won’t work.

Remember: ALWAYS remove the plastic that wraps the filter before plugging any of the Medifys in. If you forget that, you’ll end up complaining your device isn’t working effectively.


Also, filter replacement is a breeze. Grab the cartridge (containing prefilter, activated carbon filter, and H13 filter) and insert it into place. That’s all. Remove the plastic wrapping, though.


7. Made in the U.S.


Most of us have bought a product(s) made outside of the United States. And that’s ok. But here’s a self-evident truth. Products manufactured in the United States trump those made in China and other countries. That’s why US-made goods tend to be more expensive. But they also (often) last longer and perform better than knock offs from god-knows-where.

Medify is a U.S.-owned company. Every time you buy a Medify air purifier, you’re supporting America. You’re creating employment for fellow Americans. That’s a duty every American must take seriously in this day and age of cutthroat competition between countries.

But I also noted that some of the company’s representatives didn’t sound American. I felt English wasn’t their first language. In fact, one of them said he was in Asia. That’s why he couldn’t do for me a small favor I’d asked for. Is it possible the company outsources some of the manufacturing to an Asian country for obvious reasons?


8. Small American Business Owned by a Veteran


You probably didn’t know that Medify is owned by a Vet. Proud of men and women who’ve fought gallantly for America? If yes, you’ll want to support them wherever you can. If you’ve never done an act of kindness to a Vet, now is the time.

You’ve supported faceless behemoths for years. It’s about time you gave a small deserving company like Medify a chance.

Maybe you don’t want to support Medify because it’s a small business or because a Vet owns it. But shouldn’t you support them because they’re an American business that makes effective air purifiers?

9. Filter Replacement Indicator


All 6 Medifys come with a filter replacement reminder so you don’t need to remember dates. That’s really cool feature.


10. Energy Star Certification


The MA-14, MA-40, and MA-112 are Energy Star rated. But the MA-18, the MA-Smart, and MA-440 are not certified yet.

However, Medify said they’re working on getting them certified. An Energy Star certified device consumes a known amount of electricity per hour. Also, it’s significantly more efficient than one that’s not.


11. They Use a Substantial Activated Carbon Filter


Except for the MA-14, every Medify uses at least 1 activated carbon filter. The MA-112 uses 2, though. This filter comes loaded with high-surface area granulated carbon which adsorbs odors and smoke.

According to the Journal of the Air Pollution Control Association, activated carbon filters are great at eliminating smells. In fact, they remove up to 50 percent of their own weight in radioactive gases, odors, noxious gases, and fumes.

So, if toxic exhaust fumes and harmful VOCs such as formaldehyde are your scariest threats, buy an air purifier with a substantial activated carbon filter. Luckily, all Medifys use a substantial carbon filter. Meaning they remove more gaseous pollutants than thinner filters do.


Cons of Medify Air Purifiers


Very few products are 100% perfect, and Medify air purifiers are no exception.


1. Some Are Pricey


Admittedly, Medify air purifiers aren’t the cheapest devices you can buy. The MA-112, for instance, costs over $700 as of this writing. But these options are high-quality products that effectively do the job.

Pricey doesn’t always mean high-quality, though. But in the case of Medify air purifiers, however, the prices seem justifiable.

If money is a serious constraint for you, consider buying any of these budget  air purifiers under $100.


2. Most Medifys Aren’t “Smart”


Only one Medify purifier is Wi-Fi enabled. And it’s not even the one you think — not the MA-112. It’s a lower-priced model, the MA-Smart. Also, the MA-Smart is the only one in the series that’s compatible with Google Home and Alexa.

Well, the MA-440 can also be remotely controlled. But for the MA-440, you don’t even get to use an app to control the device. You get a special tablet that lets you man the thing. But you need to be within 10 feet of the air purify since you’re relying on Bluetooth technology. So, strictly speaking, only the MA-Smart is truly smart.

That doesn’t seem to make any sense to me. I feel these smart features should have gone to the MA-40 or MA-112. But that’s the way it is.

Yes, Medifys are great, but I feel more of them should be Wi-Fi enabled.


3. Some Medifys Produce Ozone


Ozone can irritate or inflame sensitive airways. People struggling with asthma or allergies are generally advised to avoid ozone generators. Some Medifys such as the MA-440, MA-40, MA-18, and MA-112 pump out a certain quantity of ozone. Good news: most of these machines are CARB-certified. I explained why this certification matters above.

I’m about to introduce you to the Medify air purifier reviews I said you’d get. At this point, I’ll answer a couple frequently asked questions about these products.


FAQs About Medify Air Purifiers


1. Do Medify Air Purifiers Work


Yes, they do. With these air cleaners, you’ll definitely detect an appreciable difference in the overall quality of your indoor air with about 48 hours. They work. You SHOULD leave the machines running 24/7 for a few days after plugging them in for optimal results.

Of course, no product clicks with everyone. I’ve read a couple adverse reviews, but the overwhelming majority of them were positive. Taken together, the reviews I saw suggest that Medifys satisfy users.


2. How Do Medify Air Purifiers Work?


These machines work pretty much like other fan-based air purifiers. They use a fan to suck in contaminated air, cleanse it, and finally push it out via into the room.

Not all air purifiers use a fan. I’ve come across some that rely on convection to get untreated air into the device. Airfree air purifiers, for instance, are fanless and filterless. But they don’t come anywhere close to fan-based air purifiers in terms of overall effectiveness.

You probably should stay away from filterless air purifiers if you can afford a Medify or any other fan-based option.

Medifys have a powerful medical grade HEPA filter to thank for their praiseworthy effectiveness. HEPA H13 filters do everything True HEPA filters do, but they go a step further than that.

Like True HEPA filters, HEPA H13 filters eliminate 99.97% of particles whose diameter is > 0.3 microns. But HEPA H13 filters also handle particles that are much smaller than 0.3 microns. Actually, these filters have been shown to remove 99.95% of particles as small as 0.1 microns!

The Medify MA-112 use 2 HEPA H13 filters, 2 substantial activated filters, and 2 prefilters. One set sits at the back of the device behind the cover. The other set stays behind the front panel. Both panels have a customized net-like pattern that improves air intake. Each set is a single cartridge containing 1 H13 filter, 1 prefilter, and 1 granulated carbon filter.

Medify MA 112

This is how the Medify MA-112 works. It uses 2 sets of filters while its siblings use one set. It’s the priciest but also the most powerful Medify there is.

Note: All the other Medifys come with a single cartridge. That means they only have 1 prefilter, 1 activated carbon filter, and 1 H13 filter. I think the Medify MA-112 is the best air purifier for people with allergies and asthma.

The prefilter chips in and captures large particles such as soot, hair, dust, and pet dander. I’m talking about PM10 particles here. The prefilter considerably reduces the amount of work the other filters have to do.

If you vacuum or wash the prefilter regularly, you’ll add longevity to the H13 filter. But that doesn’t help in any way. Why? It’s because the replacement filters come as one compact cartridge.

The activated carbon-rich filter gives the machine odor-removal ability. The filter is quite thick, much thicker than what I’ve seen in most air purifiers.

When buying an air purifier, be sure its activated carbon filter contains as much granulated carbon as possible. A filter that looks like a thin sponge with an even thinner layer of carbon does almost nada for you.


3. Do Medify Air Purifiers Help With Smoke?


Yes, they’re great at that. Medify engineers have demonstrated that their devices are some of the best smoke eliminators ever made. The MA-40, for example, clears all smoke in a 15 feet cubic smoke chamber in just 55 seconds.

If you live in an area where wildfires are prevalent, you really should consider owning one of these behemoths.


4. Do These Air Purifiers Use UV light?


5 of them don’t use UV light, but one does, the Medify MA-440. UV light exterminates bacteria, viruses, mold spores, and other such microorganisms. However, UV light also leads to ozone generation. And ozone is an irritant you should avoid if you have allergies or asthma.


5. Do these Air Purifiers Have Ionizers?


Some of them such as the MA-440, MA-18, MA-40, and MA-112 feature an ionizer. Others such as the MA-Smart don’t. You’ll know the specifics in the Medify air purifier reviews presented down the road. However, the ionizer is an optional addition, one can choose not to use. So, that’s not really a problem. Besides, the machines are CARB-rated (well, not all of them as noted earlier).


6. Do Medify Air Purifiers Give Off Ozone?


Yes and no. Those with an ionizer or UV light do while those without don’t.


7. Do Medify Air Purifiers Help Remove PM2.5?


Yes. As explained above, they remove at least 99.95% of 0.1-micron and 99.97% of 0.3-micron particles.


8. Where Can I Buy Medify Air Purifiers?


Amazon is probably the best place to buy anything these days. And that includes these and other types of air purifiers. Consider signing up as a Prime member to get the most out of being a loyal Amazon customer.

You can also visit the manufacturer’s website and order your product. But I’ve seen manufacturers selling their products at considerably higher prices than Amazon asks for the same products! That’s funny, isn’t it?

Other retailers such as Target, Walmart, and others also carry these air purifiers. I’d love it if you bought it on Amazon.

You know why?

It’s because you and I will win. You’ll get a great product at a great price. And I’d get a small commission to keep this little website up and running.


9. Are These Devices Portable?


Yes, ALL Medifys are portable. The MA-14 is the lightest of them, and it weighs just 5.3 lbs. It’s super light, yet it does the job. The MA-112 is the heaviest Medify air purifier as of this writing, weighing 33.5 lbs. Well, it’s heavier than most air purifiers, but it’s still portable. Besides, its hidden wheels make moving it quite easy.


10. Are Medify Replacement Filters Expensive?


Admittedly, Medify replacement filters are pricey.  The filter for the cheapest Medify — Medify MA-14 — costs $36 as of this writing. And they last 4 months. Meaning you’ll replace them 3 times each year. MA-18’s replacement filters cost the same price.

But that makes sense. These products filter the air down to 0.1 microns, remember. Wouldn’t you expect such a filter to get spent considerably faster than one offering less thorough filtration?

For MA-40, the filters cost $63, and they last about 6 months. You’d have to change them twice every year.

And for Medify MA-112, the filters cost $126, and they should be replaced every 6 months. You’d have to spend $252 annually on filters alone with this one.

Do I feel the prices are justifiable? You bet. These filters deliver much better air filtration than True HEPA ones do. Plus, they allow for longer contact between the filter media and air pollutants, according to Medify. Plus, they’re able to remove 0.1-micron particles. And that’s a huge advantage they have over other filters.


11. Are Replacement Filters for Medify Air Purifiers Available on Amazon?


Yes, they are. You can also buy them directly from the manufacturer.


12. What Types of Filters Do These Air Purifiers Use?


They use a HEPA H13 filter, 1 odor-reducing carbon filter, and 1 prefilter except for the MA-112 which uses two of each type.


13. What Certifications Do Medify Air Purifiers Have?


Some of them are CARB-certified, AHAM-rated, and Energy Star rated. For those that are not, Medify has applied to have them tested.


Medify Air Purifier Reviews


Which is the best Medify air purifier? Let’s scrutinize these 6 Medify air purifiers and see if they’re worth it.

So, let’s dive in.


1. Medify M-14 Review


Editor’s Rating: 4.2 out of 5 stars (4.2 / 5)


A Quick Overview


  • Dimensions: 8.26″ D x 8.26″ W x 12.20″ H
  • Weight: 5.3 lbs
  • Design: Slim rectangular shape. Sleek and simple
  • Color: White
  • Filters: 1 prefilter, 1 HEPA H13 filter, no activated carbon
  • Filter Life: 4 months
  • Air Quality Sensor: No
  • Filter Replacement Light: YES
  • Smart Features: No
  • Timer:NO
  • Ionizer: NO
  • Child Lock: NO
  • Fan Speed: 3
  • Area Purified: 200 square feet
  • CADR: 120
  • Energy Star rating: YES


The Medify MA-14 offers impressive air cleaning effectiveness in a sleek, simple package. It’s designed to freshen the air in bedrooms, dorm rooms, baby nurseries, and enclosed offices. Its cleaning power covers up to 200 square feet.

The unit’s easy-to-use control panel is on the machine’s front-facing side. You can power the machine on and off and choose one one of 3 fan speeds. You can also turn the sleep mode on or off. Or turn off all the lights on the control panel.

Suppose you run the MA-14 on high in an enclosed area measuring 12 ft. x 10 ft. for 60 minutes.  The device would circulate the air at least 4 times. And if the area were larger (470 sq. ft.), the machine would circulate the air once in 60 minutes. The smaller the room, the more the circulations.

Standing only 12.20″, this unit isn’t bulky, so,  no headaches when handling it. Also, it looks cute. You can place it in the living room without worry.

Its HEPA H13 filters remove 99.97% of larger-than-0.3-micron particles and 99.95% of particles 0.1 microns or larger. That means it’s great for PM10 and PM2.5 removal.

Unfortunately, the unit lacks an air quality sensor. So, you can’t see how much PM2.5 it’s removing. It works, though. Users typically notice an appreciable difference in their indoor air quality in about 48 hours.

On low, you might think the machine isn’t pulling at all — it’s super quiet. Place it in your bedroom, and you’ll sleep peacefully through the night.

On medium, the MA-14 moves the air more powerfully, and quite predictably,  it’s a little louder. But it’s a white noise that pretty much anyone can take.

On the highest setting, the highest level of noise the machine produces is 55 decibels. That’s a bit loud, and I doubt a light sleeper would fall sleep at that speed. But that’s the maximum level of noise I’ve seen with many comparable devices.


Maintenance and Energy Consumption


You’ll have to replace the filters 3 times each year. The filters cost around $40 on Amazon. But Medify Air sells them at a cheaper price. So, that’s about $120 on filters annually. That’s about as much as the unit’s cost.


In general, high-quality lower-priced models tend to have relatively expensive filters. But $120 for air with considerably less PM10 and PM2.5 doesn’t look like such a bad deal.

The unit’s rated power consumption is 26 watts or about 227.76 kWh per year. At a rate of 10 cents per kWh, you’re looking at $22.78. The annual cost of operating the MA-14 therefore adds up to about $142.78.




  • Lifetime warranty
  • Portable
  • Simple, sleek design
  • Filter change indicator
  • CARB-approved
  • CADR-rated
  • Energy Star rated
  • No ozone
  • Night mode
  • Great price




  • No activated carbon filter
  • No air quality sensor
  • Not Wi-Fi &Alexa-enabled
  • Night light too bright
  • No timer


Comparable devices come with an activated carbon filter, but this unit doesn’t. That’s not something I like. However, the HEPA H13 filters the air down to 0.1 microns.

And unlike the higher-priced MA-112, this unit offers 1 prefilter and 1 HEPA H13 filter. But that’s pretty much what comparable competitors offer. So I won’t count that against the unit.

But I’d love to see a particle sensor. It’d also be nice if they incorporated smart features such as Wi-Fi and Alexa in future versions of this model. Low-priced models tend not to have smart features, though.

However,lack of smart features doesn’t detract from the machine’s usefulness.

Would you like to check out a couple more low-cost air purifiers that work? Here’s a list of 5 effective air purifiers that cost under $100.

It’s nice that the unit features a night mode, too. You can use it as a night light. Simply turn it on, and you get a blue light that fades in and out of your bedroom.

But this light might be too hard on some eyes. So, how do you shut off the intrusive MA-14’s nightlight? It’s easy — go to the control panel and press the light icon.

And what does Medify’s lifetime warranty mean? I posed this question to Medify Air. They said they’ll replace faulty parts or even the whole unit throughout its life. However, the user MUST have been replacing filters every 4 months (for this unit).

It’d also be nice if it had a timer. Luckily, the unit isn’t a power guzzler.

The MA-18 is among the cutest and easy-to-operate air purifiers I’ve ever seen. It’s a mid-range air cleaning device made for 380 sq. ft. rooms. Unlike some of its siblings, this unit has an elegant cylindrical design. It’s a practical design that supports 360-degree air intake. Sanitized air comes out via the top, in all directions.

Although Medify Air says this unit is meant for 380 sq. spaces, I’d recommend it for a much smaller room, especially if you battle allergic reactions. If you have asthma or allergies, use it for rooms not a square foot larger than 200. In such a room, you should get at least 4 air circulations every hour.

Generally, people with respiratory issues should pick air purifiers whose ACH in their room is at least 4. Pro tip: ALWAYS buy a machine designed for a significantly larger room.

This unit comes in a modern design that offers touchscreen convenience. The control panel sits atop the unit, and it features 4 responsive buttons. There’s a power button to turn the unit on or off. Also, there are 3 buttons marked 1, 2, 3 representing 3 fan speeds namely Low, Medium, and High.

On low, the unit operates surprisingly quietly. The medium setting gets a bit louder, but nothing insane. You’ll sleep soundly at this setting. On high, it gets quite loud, as you’d expect. But that’s because it’s moving tons of air per minute.

This machine uses a 3-in-1 filter comprising of a prefilter, an activated carbon filter, and a HEPA H13 filter. If you have dogs or cats and are a little worried about pet odors, you can use this unit. It removes pet odors, smoke, cooking odors, and other odors pretty well.

Well, your dog’s bed may still smell like your dog. But the smell will stop wafting out to the rest of the house. Other contaminants eradicated include household dust, dust mites, pollen, mold, and pet dander.

It’s also quite effective, like all Medifys, for removing VOCs such as formaldehyde and benzene. That makes this machine a great companion for people living in areas with heavy traffic pollution.

Lastly, there’s an optional ionizer that helps keep the air smelling clean and fresh.

Maintenance and Power Consumption


Filter replacement should be done after every 4 months. But you’ll change the filters sooner than that if you live in a highly polluted area. They cost about the same price as those for the MA-14. So, be ready to shell out about $120 annually for filters.

As to power usage, this unit consumes about 35W. In a year (assuming the unit runs 24/7), you’d spend about 306.6 kWh. At 10 cents for every kWh, your electric bill would grow by about $30.66, bringing the total to about $150.66.

Do you think paying that much for unadulterated air makes sense? I think it does.

At that price, I’d expect the unit to have an air quality sensor. But the thing works, and the air feels clean and fresh within hours of installing it.

Well, the unit produces a certain amount of ozone whenever the ionizer is turned on. However, the concentration stays within safe limits (0.05 ppm). But if you don’t like the idea of breathing in whatever amount of ozone, just turn the ionizer off.


3. Medify MA-40 Review


Editor’s Rating: 4.2 out of 5 stars (4.2 / 5)


A Quick Overview

The MA-40 is the smaller version of the Medify MA-112. And it offers all the features its larger sibling does. But unlike the MA-112, the M-40 uses one set of filters.

It’s black or white, and as you know, these colors blend in well with most colors. When it comes to air purifiers, I’ve seen real eyesores, but this isn’t one of those. Place it anywhere you want around your house. And since its weight is only 15.5 lbs, moving it should be easy.

This unit offers 2 air changes per hour in rooms measuring 800 sq. ft. If you’re asthmatic, though, you’ll want to use the unit for spaces not larger than 400 sq. ft. The device would circulate the air 4 times in 60 minutes in an area that large. Of course, you’d get more air changes per hour in a smaller room.

Like the MA-18, this machine uses a prefilter for trapping pet hair, fibers, pet dander and other large particulates. It also features a highly efficient H13 HEPA filter, like all Medifys. And its medical-grade HEPA filter eliminates 99.97% of particulates equal to or larger than 0.3 microns. This filter takes away your worries regarding pollen, dust, asbestos, dust mites, mold spores, and more.

The unit’s substantial carbon filter with carbon pellets tackles toxic fumes, odors, smoke, and VOCs such as formaldehyde. Evidently, it’d be a great device for people living in areas receiving high levels of vehicular pollution.

Also, it features an optional negative ion generator (ionizer). The ionizer releases anions into the air, giving it a fresh, clean feel. Have asthma or live with allergies? Don’t worry. The ionizer is an optional feature, you can easily turn it off.

Unlike the MA-14 and 18, the MA-40 comes with an auto shutoff timer. This addition lets you instruct your machine about how long it should run before turning itself off. That’s a cool feature for people who are away working for hours each day. Is that you? If yes, you’ll always come home to squeaky clean air that smells fresh and healthy. You can time your device to automatically turn itself off after 1, 2, 4, or 8 hours.

Replacing the filters is very easy, too. Simply remove the panel at the back of the machine and snap them into place. All 3 filters come in a single cartridge, so you won’t waste time.

The control panel is made of high-quality tempered glass that doesn’t scratch easily. And it sits on the top of the unit. It’s the kind of glass used for modern mobile phones. That makes it very easy to clean. Just grab a soft piece of cloth and wipe away the dirt.

All the device’s features are on the control panel. The sensor assesses your room’s air quality and tells the fan what to do. If the air is bad, the fan automatically ramps up the fan speed and vice versa.

The sensor is on the unit’s front-facing side and changes in color to reflect the current indoor pollution situation. If the air is good, the sensor shows blue. And if the air is just ok or fair the color turns green. But if the air quality needs massive improvement, the color becomes red.

I think it’d have been better to have blue indicating “Ok” and green meaning “Good.”

Other features: child lock that keeps kids from interfering with your settings.  There’s also an optional ionizer.

Maintenance and power consumption


Filters should be changed semiannually. At the moment, they cost around $40 on Amazon (prices keep changing), so that’ll set you back $80 every year. It’s Energy Star rated and consumes about 68 watts per hour. If you run it 365 days a year, you’ll ratchet your energy bill by about $59.57. The total costs would be $139.57. That’s how much you’ll part with for a constant supply of clean, healthy air.

  • Not Wi-Fi & Alexa enabled
  • Air enters via the back and exits via the front


Given the unit’s price, I feel Medify Air should have given consumers at least the Wi-Fi feature. I’d have recommended something else, but when I remembered the thing cleans the air down to 0.1 microns, I changed my mind. But this is something I don’t like about this otherwise awesome deal.

With this design, the air enters via the back, gets worked on, and exits via the front. For that reason, you won’t want to place this device behind a wall.

Note: the unit comes loaded with the filter already. But you shouldn’t start using the machine before removing the filter from its plastic cover. So, remove the lid at the back and take the 3-in-1 filter out. Next, remove the plastic cover and then reinsert the filter into place. Finally, plug the device in.

Another thing: make sure the tabs are sticking out when inserting the filter. That makes filer replacement very easy. And that goes for all other Medifys.


4. Medify MA-112 Review


Editor’s Rate: 4.5 out of 5 stars (4.5 / 5)


A Quick Overview


  • Dimensions: 15.3″ D x 15.7″ W x 28.3″ H
  • Weight: 33.5 lbs
  • Design: Rectangular, sleek, modern
  • Color: Silver
  • Filters: 2 prefilters, 2 HEPA H13 filters, 2 activated carbon filters
  • Filter Life: 6 months
  • Air Quality Sensor: YES
  • Smart Features: No
  • Fan Speed: 4
  • Timer:YES
  • Ionizer: YES
  • Child Lock:YES
  • Has Wheels
  • Area Purified: 2,400 square feet
  • CADR: 950
  • Energy Star rated: YES


Despite being the priciest, the Medify-112 is the most popular Medify air purifier. It’s also the heaviest, and about 1.5″ shorter than the MA-440.

Luckily, it has hidden wheels that make wheeling it to where it’s needed a breeze. I like that the wheels stay hidden from view.

It’s not bulky, though. It stays out of the way.

And yes, this purifier is pricey. It costs over $700 as of this date. But it delivers. I can’t think of a more accurate description for it than the following: Cute, Compact, Modern, and Powerful.

Yes, the thing is damn powerful. It moves an insane volume of air on its highest setting. But on that setting, it’s intolerably loud.

On low, most new owners are surprised that such a powerful machine is that quiet. On medium, the noise increases significantly. However, its not worse than white noise that drowns out other noises. In fact, many people like running their machine on medium when going to bed. They say the noise lulls them to sleep.

Unlike its siblings, this unit uses 2 prefilters, 2 substantial carbon filters, and 2 H13 HEPA filters. It features two sets of powerful filters, 3 behind the front panel and 3 at the back. I’m talking of 6 filters here.

Evidently, the MA-112 takes air filtration to a whole new level. That’s another reason I believe it’s the best Medify there is as of this writing.

The device draws dirty air in from two sides, the front and back. Do you know what that means? It means more comprehensive air filtration. Small wonder the MA-112 is the fastest and most powerful Medify air purifier.

Can you believe it changes the air in a 2,400 square feet enclosed space 2 times every hour? And in a 1,200 square feet room, the occupants see 4 air changes in 1 hour.

Doesn’t that sound like the best air purifier for a stuffy basement?

The unit’s 2 H13 HEPA filters remove up to 99.97% of particles with a diameter of 0.3 microns or larger. But what makes these filters special? What makes them superior to True HEPA filters? It’s because they offer a more thorough filtration. These filters have been tested to eliminate up to 99.95% of 0.1-micron particles or larger. This is the one fact that sets Medifys apart from every other category of PRAC (portable room air cleaners).

Do you live next to someone who smokes cigarettes or even marijuana?  Yea, I know how that must feel. The smell seeps into your space the whole time they’re having fun. And that annoys you no end. But it’s their apartment, and they’ll continue having fun whenever they want.

Well, you could sue them, according to the American Nonsmokers’ Rights Association. Strictly speaking, though, no law bars people from smoking in their apartment. But wait, do you you live in a multi-family property?  With respect to such housing, some states and municipalities prohibit smoking in common areas.

You could sue the landlord and argue that they’ve let the place become inhabitable.  Or the weed-loving neighbor and argue that their habit interferes with some of your rights.  But court cases can drain you emotionally and economically. Plus, judges sometimes rule in favor of the smoker. Suing your smoking neighbor isn’t worth the hassle in most cases.

So, what’ll you do? Try out the Medify MA-112. You’ll love it.

Whether your problem is pet odors, marijuana smoke, wildfire smoke, or toxic exhaust fumes, the MA-112 is the real deal. I’ll let you in on a little secret. Of all the recommendations I’ve ever given on this website, the Medify-114 has received the most attention.

My readers buy tons of these air purifiers, and that’s no accident. Within 48 hours, your indoor air should feel a lot more fresher and cleaner than it’s ever been. This is probably the finest and most powerful air purifier in that price range.

How large is your moldy basement? 600 square feet? Don’t worry. Just grab this beast. It has a CADR of 950, and you likely won’t find a better deal at that price. The manufacturer says to use the device for spaces as large as 1200 sq. ft. But my advice is use it for a smaller space to boost effectiveness.

Let’s ignore what the manufacturer says and focus on AHAM’s 2/3 rule. If we follow this rule, we see that this device is best suited for rooms with a square footage of 633. That is, (2/3 x 950). As you can see, the device works best for basements measuring about 600–650 sq. ft.

Want to know what would happen if you selected the highest fan speed? You’d get an ACH of 8,. Yes, that’s right, you’d get 8 air changes per hour. You can now see why I said the machine a monster.

Like all Medifys, this purifier comes with a filter replacement reminder. Also, it has an air quality sensor that changes color depending on how clean or dirty the place is.

When the room is too dirty, the color shown is red. If the air quality is neither good nor bad, the color displayed is green. But when the machine finally purifies the air, the color turns blue. I feel that they should have used green for Good and blue for Fair.

In addition, the device shows you real-time PM2.5 numbers. You’ll see an actual number representing the actual air quality situation in your room. The higher the reading, the worse the quality is and vice versa. I like that the unit shows real-time PM2.5 numbers. These particles are very dangerous because they’re much smaller than PM10. If not controlled, they’ll finally end up in the body’s most sensitive organs including the heart and brain.

The unit’s easy-to-use control panel is the first thing you see when standing next to this thing. It features 6 clearly marked buttons, which makes using the machine completely pain-free.  The first button is the On/Off followed by the fan speed one. The next one is the auto mode button followed by the 1, 2, 4, or 8-hour timer.

Wouldn’t it be nice to be able to shut the thing off after a certain duration so you can save energy? The timer helps you do precisely that.

The auto mode offers lots of convenience. It’s a set and forget it feature that lets the machine operate itself. The auto mode button doubles up as a child lock. When you turn the feature on, your child can’t input a different setting.

Changing the filter for the unit is incredibly easy, too. The nice thing about Medify filters is that they come in one cartridge. You won’t need to insert the 3 filters one after the other. Once you buy the replacement filters, tear the plastic cover and simply fit the cartridge inside the purifier. It’s that easy.

Then there’s the sleep mode. Turning the night mode on dims the control panel’s brightness so you can sleep without issues. This mode also reduces the fan speed so that your device runs on low throughout the night.

Finally, you have the optional ionizer. Keep it turned off if asthma and allergic reactions bother you. If you have no breathing issues, consider leaving the ionizer turned on. It infuses the air with negative ions, and that has it feeling noticeably clean and fresh.

The ionizer gives off a little ozone, though. But the unit is CARB-tested and approved. That tells you that the concentrations pumped out never exceed safe levels (0.05 ppm).


Maintenance and Energy Consumption


Change the filters every 6 months or earlier if your air is really bad. Well, these filters are quite expensive. They’re selling at almost $140 on Amazon as of this writing. But you can get them at a slightly lower price on the manufacturer’s site. Since you’ll buy these filters twice a year, the total cost for filters would be $280.

Luckily, this thing is Energy Star rated. It’s energy-efficient, and its rated power consumption is 95W. And that seems reasonable for a device this powerful. In a year, this sucks about 832.2 kWh of power.

If you multiply this number by 10 cents (assuming  1 kWh costs 10 cents), you get $83.22. The total cost of running this air purifier nonstop for 1 year is about $363.2. Well, that seems like a lot. I’d certainly not borrow to buy this. But if money isn’t tight for you, go for it. It’s worth every penny.

For a device that pricey, I feel the MA-112 should offer smart features, specifically Wi-Fi and Alexa. What’s better than being able to use your smartphone to operate your device? And wouldn’t you love being able to say “Alexa, Tell Medify to turn fan speed to 3?

While these features don’t make the unit any less usable, it’d be really nice if they were included. However, this shouldn’t be a dealbreaker for most people. The many other great benefits the thing delivers sort of compensates for this.

And while it’s pricey, you can’t say the price seems excessive. For me, it’s a terrific machine with a reasonable price.

If it’s in your price range, buy it now. You’ll love it. I’d not be surprised if you came back here and order another Medify a month from now.


5. Medify-440 Luxury Spar 4-in-1 Review



Editor’s Rating: 3.5 out of 5 stars (3.5 / 5)


A Quick Overview


  • Dimensions: 8.26″ D x 8.26″ W x 12.20″ H
  • Weight: 25 lbs
  • Design: A slim, sleek design with a brown, textured front panel
  • Color: Brown and grayish

  • Filter Life: 6 months

  • Area Purified: 700 square feet
  • CADR: 220
  • Additional Features: Spa experience, aromatherapy, 16 relaxing sounds, and humidifier
  • Energy Star rated: Not yet
  • Uses UV light


The MA-440 stands out from its siblings in several ways. Actually, it’s a 4-in-1 deal, one you’ll want to try out. It looks like a giant, sleek smartphone standing on a sturdy base.


The Air Purifier is All of the Following:


  1. It’s a humidifier.


  1. It’s an air purifier.


  1. It’s a mini-spar.


  1. It offers up to 16 relaxing sounds that lull the user to sleep in no time.


Imagine saving tons of money on expensive spar experiences while breathing squeaky clean air scented with refreshing aromas? That’s the exact same experience you’ll get if you install this air purifier in your bedroom, office, or living room. The manufacturer made the unit with hotels as the target market. But who says you can’t enjoy hotel-like comfort right in your room?

The MA-440 is the device you want to use when winter comes around. Winter air should be moist, but it’s naturally drier than air in any other season.

Dealing with a severe winter is extremely challenging, and winter depression happens a lot. According to the National Sleep Foundation, the affected person feels less energetic and irritable. Health experts have given winter depression a technical name: it’s a Seasonal Affective Disorder.

When you’re feeling this down, the last thing you want is more problems. But you can’t stop breathing. And the air is dry and heavy, making things feel a lot worse . If you have an MA-440 humming away in your room, winter will be a lot more tolerable. Even enjoyable.

This air purifier is like a mini-spar. If you’re like 25 percent of Americans, you’ve visited a spa at least once. It’s no accident that spas have become super popular these days.

Visiting a spa delivers quite a few benefits. The spa experience helps reduce stress and makes you feel comfortable. Also, the body sweats, letting toxic substances out the body. I’m talking about natural detoxification of your body here.

Aside from that, the spa experience has been associated with a decreased risk for heart disease, cardiovascular diseases, and even early death. All these benefits add up to improved health and better sleep. Yes, better sleep. If you have trouble falling asleep, use this machine and see what happens. You’ll start sleeping like a log soon after crawling into bed.

Spa sessions aren’t the cheapest experiences out there. A spa session in a decent hotel in a major U.S. city can cost as much as $200. If you enjoy 5 weekly spa treatments, that’s $1,000. Well, that looks pretty much like rent money or car payment!

Fortunately, there’s a way to keep your costs down while enjoying a much better quality of life. Here’s the spar alternative: the MA-440. If costs around $400 or thereabout as of this date. Please note that prices keep changing. The unit may cost significantly less or more by the time you get to read this post.

Maybe you’re not paying $200 per session. Maybe you’re paying something like $50 per 45 minutes of spar experience in your city. If you receive 2 treatments each week, you’ll spend $400 every 1 month. But why continue spending that much when you could just use the MA-440? In just 1 month or so, this thing will have paid for itself.

The MA-440 offers many great features that come together into a comprehensive system that delivers tons of comfort. Its moisture function spews mist out into the room, moisturizing that dry, nasty winter air. And don’t worry about washing the tank — simply put the UV sanitized cool mist function to work.

When researching for this purifier, I couldn’t believe so much technology and functionalities could co-exist in one machine. Can you believe there’s a pump in there so you won’t have standing water ? There’s even a water purifier complete with a UV light so no harmful microbe ends up in your air. What’s not to love about the MA-440?

How long does the water reservoir used by the MA-440 last? It holds about 1 gallon, and that’s enough for one night (about 8 hours).

Now let’s talk about aromatherapy. Different cultures around the world have used aromatherapy, also referred to as essential oil therapy, for thousands of years. Today, thousands of companies have sprouted everywhere, claiming that their oils do this or that.

You might have heard that aromatherapy can help with asthma. But no scientific evidence (as of now) supports this claim. Essential oil therapy DOESN’T help allergy or asthma.

In fact, you may want to avoid these products if you have breathing issues. That’s because inhaling these oils (think VOCs) may cause irritation to your airways, worsening a bad situation. Aside from that, these oils may also cause irritation to the skin. If you have sensitive skin, stay away from them. Finally, these oils may harm children if swallowed. So, keep them out of children’s reach always.

Aromatherapy isn’t meant to treat any disease. So, don’t use any oil purported to help asthma without consulting your doctor. And if you want to use them, make sure to buy from a trusted company. Why? It’s because the FDA doesn’t regulate essential oils.

Now, we’ve got that out of the way. Now, let’s talk about the good side of aromatherapy — its benefits. Aromatherapy is believed to help relieve pain, soothe joints, and even improve digestion. It may also help reduce stress, treat migraines and headaches, and boost the body’s disease-fighting ability.

What’s more, aromatherapy may help users sleep better while making them feel less anxious. Aside from that, it may help address discomfort during pregnancy.

Whether these benefits are scientifically proven or not, users of essential oils love them. Maybe they love them because they work for them? Who knows. Here’s the thing: the MA-440 is an essential oil diffusing air purifier.

It comes loaded with 4 refreshing smells including Eucalyptus, Island Breeze, Vanilla Mist, and Lavender Chamomile. You, your family, and visitors will love the scents that’ll pervade your home or office.

Does it take you hours to fall asleep? That comes to an end with this air purifier. That’s because on top of spewing out healthy, sleep-inducing essential oils, the MA-440 also produces at least 16 relaxing soundscapes.

Some of these sounds are white noise, pink noise, and brown noise. You’ll also get nature sounds such as rain, ocean sounds, and night sounds. There’s also medication and spa sound categories. All of these sounds are an extra addition whose priority is to help you relax and fall asleep.


The Control Pad for the MA-440


You likely imagine this air purifier comes dotted with many hard-to-figure-out buttons. On the contrary, the machine is quite easy to use, not finicky at all. It comes with a detachable 7″ tablet. The tablet has a simple user interface with large buttons, making operating the device a breeze.

Can you remote-control the MA-440? Yes, you can. The tablet is Bluetooth-enabled. It’s a special tablet that connects to your machine, allowing you to remote-control it. You can place the device on your nightstand for hassle-free control. 

Here’s one more benefit of this air purifier. Like the other Medifys, it offers a sleep mode. If you feel that the light coming from the control panel (tablet) is too bright, dim it. Go to the lower left corner of the tablet and tap it until you have a soft enough level of brightness. Dimming the light also lowers fan speed so you can sleep without disturbance.

Also, the tablet reminds you when it’s time to replace the filter which lasts around 6 months. Also, when any component isn’t working properly, you’ll see a notification on the tablet.

Is the MA-440 quiet? The machine struck me as surprisingly quiet on low and medium. It gets quite loud on high and Turbo, though, but it’s not deafeningly so.  That’s because it uses high-quality DC motors that muffle the noise. Even when on Turbo, the machine produces no more than 55 decibels.

The unit offers 4 fan speeds namely Low, Medium, High, and Turbo. High and Turbo are for when you have nasty allergies and allergy season’s just kicked in. Leave the behemoth roaring for some time and then switch back to a lower setting, preferably medium.

Finally, there’s an optional anion generator that ionizes the air, trapping pollutants inside the unit. If you’re sensitive to various allergens, consider keeping the ionizer turned off. But if you have no allergies or asthma, you’ll love what the ionizer does to your scented, purified air. With an ionizer, the air feels fresher and cleaner.

This air purifier treats about 700 square feet rooms by circulating the air 2 times every 60 minutes. If the area is smaller (350 sq. ft.), the ACH rises to 4. Like every other Medify purifier except the MA-112, this one uses 3 filters that come in one cartridge.  There’s a prefilter, an activated carbon filter, and a H13 HEPA filter. The unit removes 99.95% 0.1-micron pollutants and 99.97% of 0.3 micron or larger ones.


Energy Consumption and Maintenance


The MA-440 gobbles up 120W which sums to about 1051.2 kWh annually. Your electric bill will grow by about $105.12. Add the yearly filter replacement of about $250, and the cost grows to $355.2. Evidently, owning the MA-440 is pretty much like owing the MA-112 in terms of costs. While this machines demands serious financial commitment, it delivers tons of benefits as described above. But the price could sure be a little lower than that.



  • Provides spar-like experiences
  • Aromatherapy benefits
  • Humidifies the air
  • Filters down to 0.1 microns
  • Portable
  • Slim, sleek design
  • Optional ionizer




  • Recently released
  • No reviews anywhere
  • Energy guzzler
  • Replacement filter expensive
  • May produce ozone


I’ve not encountered many air purifiers of any kind that consume 120W. But the MA-440 consumes that much energy. But that’s expected considering how much work this thing does. It’s humidifier, an air purifier, and a spa at the same time.

If you buy an air purifier and a dehumidifier, you’ll likely end up consuming the same amount of energy. Also, consider just how much spa money this unit would save you. The additional $106 in your power bill won’t seem like much.

I also noted that the machine entered the market recently. That’s why there isn’t a single review on Amazon and even on the manufacturer’s site. But why worry when you can always return the thing if it’s not working? Remember: the MA-440, like every other Medify air cleaner, offers a lifetime guarantee.

I’m not surprised that filters for this air purifier aren’t available on Amazon as of this writing. But they’re available on the manufacturer’s site. That’s because the unit is newly released by Medify (more on this later). They’re selling them at around $125, and they should be replaced twice every year.

does anyone think a company would sell air purifiers without availing parts and filters at some point? Actually, they told me that a truck carrying replacement filters was on its way to Amazon’s warehouses. They should be available pretty soon.

Well, the thing produces ozone if you leave the ionizer on. And as at 18.10.2019, the machine isn’t CARB-approved. I can’t say whether the quantities of ozone it pushes out are well within safe levels. But I honestly think the MA-440 will get approved just like its siblings were. Medify confirmed to me that this product has been entered for consideration with CARB. I’ll come back here and update this list down the road.

Quite frankly, I’ve not used this machine. I have 2 Honeywells and one Dyson, and they’re still serving me well. But don’t worry, I research extensively and keep engaging with manufacturers to make sure you get accurate reviews. The MA-440 4-in-1 looks like a great air purifier, judging from the specs and features.

NOTE: I dug around a bit about this machine (since it lacks reviews on Amazon) and learned something interesting. Medify, the manufacturer of the MA-440 was established in 2017. But this device itself was released in 2014!

When I questioned that, Medify said that the MA-440 used to be sold under another brand called AireSpa. The brand was owned by a seemingly small company called Innovaci.

So, I checked out AireSpa. And the device I saw there looks pretty similar to the MA-440. But that company had only one product (the AireSpa), and I assumed they must have been acquired by Medify Air or something.

I trust Medify Air, though. Why? It’s because the company has released 6 major products. That means quite a lot. That doesn’t look like a fly-by-night outfit to me. And save for the MA-440, the rest of the air purifiers seem to have rave reviews on Amazon.

Frankly, though, I’d hesitate to buy the MA-440. Even though it’s associated with a seemingly stable company, there are no reviews yet. But there’s no reason not to buy it and see if all its amazing features work as promised. After all, the lifetime warranty protects you. The main reason I rated the unit 3.5 is that it has no reviews at all.

The Medify MA-Smart is the first and only smart Medify air purifier. When was the MA-Smart released? It’s released on May 2, 2019 in New York, U.S.A.

It’s supposed to clean 1,000 square feet every 60 minutes. That’s one air circulation per hour, which isn’t good enough if you’re asthmatic. It’s pointless to use this in a 1,000 square feet area.

If you have the unit in a 500 square feet room, it’ll do 2 air circulations in an hour. That’s better than just one circulation in an hour, but it’s not good enough. Buy the unit for a room not larger than 250 square feet because you’ll get at least 4 air changes per hour. Now, that’s a good enough ACH for everyone, including asthma and allergy sufferers.

The MA-Smart is Wi-Fi and Amazon Echo enabled. You can verbally give it instructions on what to do. You can also control it via your smartphone. If you’re the type that worships at the altar of technology, choose this air purifier.

The unit’s easy-tap control panel sits on the top. All the buttons you’ll ever need to operate the machine are there. It’s a clean, easy-to-operate panel, unlike many finicky ones I’ve seen.

To make the most of the device’s smart features, you’ll need to have the right devices. You need a smartphone/tablet to leverage the unit’s Wi-Fi capability. And you need Amazon’s Echo or other similar speaker to get the most out of Alexa.

Download the Smart Life App and link your phone to it. You should easily control the purifier from any corner of the house. No longer will you need to pad across the room to give a command to the machine. Note: to pair up your air purifier with the Smart App, you need a 2.4 GHz Wi-Fi connection. You can’t use 5 GHz networks currently.

For Alexa, you’ll have to download the Alexa app as well as the appropriate skill and connect your air purifier. It’s easy, takes minutes. Once you do that, you can control your machine from anywhere. And you can actually speak to it, which is cool.

Like all Medifys except the MA-112, the MA-Smart uses a 3-in-1 filter. The filter comes pre-installed. All you’ve got to do is plug it in. But wait, have you removed the plastic sheath that covers the filter? DON’T use the machine until you’ve done that. Same goes for the other 5 air purifiers from this company.

And like the MA-18, the MA-Smart features a simple, sleek cylindrical design. I’d say the MA-18 looks better than its sibling. Maybe that’s just my eyes. But if aesthetic appeal was the only important aspect, I’d rather have the MA-18 sitting in my living room than this option.

Every purifier from this brand uses a HEPA H13 filter to get rid of up to 99.97% of particles larger than 0.3 microns. And this air purifier is no exception. If there are 100,000 mold spores floating in your air now, this machine would bundle out 99,970 of them!

It gets better. This filter has been tested to eradicate about 99.95% of all particles 0.1 microns or larger. It can’t get better than that. The Medifys are a rare cluster of air purifiers with the capability of filtering down to 0.1 microns. That’s a really good thing since the smallest particles are usually the most lethal.

But before the air gets to the H13 filter, it passes via the prefilter. The prefilter is normally included to do preliminary filtration before the air passes on to the medical grade filter. It removes large-size particles including pet hair, pet dander, some dust, lint, and more. As a result, the main particulate matter filter (H13) will have less work to do. And that means it’ll last longer than it would if there was no prefilter. But that’s of little consequence since the filters come as a single cartridge. Meaning they’ re changed at the same time.

The last filter in the 3-in-1 cartridge is the activated carbon filter. This filter is included to help reduce odors and toxic VOCs such as formaldehyde.  The 3-in-1 filter will typically serve you for 4 months before replacement.

With this or any other Medify, formaldehyde, benzene, and other VOCs will stop adulterating your indoor air. Or at least, they won’t bother you as much. I think this machine and all its siblings are the best solutions for road traffic pollution. They’re also great at removing construction dust, mold, asbestos, pollen, tobacco smoke, and more.

Ask any allergy and asthma sufferer that uses a Medify. They’ll tell you there’s nothing better in life than being able to breathe without difficult. They no longer fret over the possibility that they’re inhaling gallons of PM2.5 every day.

Using a powerful motor, this device sucks in dirty air from all directions. Most air purifiers pull in just one or two directions. Such air purifiers must be positioned  centrally, sometimes getting in the way. Good thing is you can place this smart thing behind a wall, and its effectiveness won’t reduce dramatically. The air comes out via the top, just like it does in all air purifiers offering 360-degree air intake.

You can choose any of 4 fan speeds, or you can opt to have it purify on auto. On low, it’s very quiet. One medium, it gets louder, and that’s not surprising. But it’s not disturbingly loud on the setting. At worst, it’s white noise which most people actually like. On high, it does get pretty loud, and a light sleeper probably won’t sleep well.

Other features offered by the MA-Smart include filter replacement indicator, air quality sensor, sleep mode, and auto shutoff timer.

The sleep mode switches the unit to low which dims the control panel lights. And the timer makes it possible to decide how long your device should clean the air before shutting itself off. The available options are 1,2,4, and 8.

In my opinion, a timer is one of the most important features in an air cleaning device. It boosts the unit’s convenience. Plus, it can save you lots of energy over the long term.

Let’s now look at this air cleaner’s air quality sensor. You’ll see a 360-degree base light that changes color in accordance with changes in the room’s air quality.

When the quality is good, the color stays green and when it needs a little improvement, it displays yellow. But if the air is swarming with allergens, the color you’ll see is red.

Consider setting the unit on auto so it can adjust its fan speed in accordance with your room’s current air quality situation. If the air needs a bit of filtration, the sensor commands the unit to crank up the fan speed. And once the air is clean, the reverse happens — the unit returns to a lower speed.


Maintenance and Energy Consumption


Filter replacement should happen every 4 months. At this point, I can’t seem to find replacement filters either on Amazon or the producer’s site. But I emailed Medify Air, and they did say they’ll release replacement filters for this unit in 2 weeks. Actually, they said a load of filters was on its way to Amazon. The filters will cost $59, which is kind of steep. That’s going to be $177 annually on filters and electricity.

I engaged Medify Air about the issue of Energy Star certification. They said the unit isn’t rated yet. However, they did say they’d applied for the same, and they’d get back to me once they heard from the EPA.

However, they told me the thing uses 50W, and that adds up to 438 kWh per year. That’d cost you around $43.80, and the total costs would come to $220.80.

Well, that’s more than the cost of the device. The thing works, though. You must decide whether $221 seems reasonable to you. One thing you need to know is that high-quality filters aren’t cheap. And cheap filters usually don’t do a thing for the user.

This purifier is yet to get approved by CARB, and it’s not Energy Star rated. But the manufacturer told me they’d applied to CARB for consideration. The machine’s siblings got a clean bill of health from CARB recently. And there’s no reason to believe this unit won’t endure the tests.

Even though it’s not CARB rated, you have nothing to fear since it doesn’t produce ozone (has no ionizer). And while it’s not Energy Star rated, it consumes only 50W. That’s how much energy your laptop consumes in an hour.

I love that the device is smart. You can turn it off or on from a different room. You can also fire it up or power it off even when you’re away from home. It’s Wi-Fi enabled; you can connect it to the Smart Life app for more convenience.

Also, you can link the MA-Smart to Amazon Alexa. If you do that, operating your device becomes easy and fun. Simply tell the thing, “Alexa, turn on air purifier.”

However, you can’t pair the unit up with the Smart App unless you’re using a 2.4 GHz Wi-Fi connection. So, you may need to adjust the settings on your router.  Currently, 5 GHz Wi-Fi networks aren’t supported. But that’s not a problem. Why? Because the 2.4 GHz frequency happens to be the standard with all internet providers.

But why won’t the ring of light that encircles the MA-Smart’s base turn off? Luckily, the light isn’t too hard on the eyes. It wouldn’t bother most people. Besides, you can always select the sleep mode which automatically turns the light off.

The MA-Smart is the only Smart Medify I’ve seen. I asked the company why the MA-112 wasn’t a smart device despite it being pricey. The answer I got seemed to make some sense. They researched and found that many consumers actually didn’t value smart features that much. And that people usually operated their purifier without using these features even when the machine had them. Do you think they’re right? Let me know in the comments.


Medify Air Purifier Reviews: Overall Winner


You’ve read all 6 Medify air purifier reviews. Have you identified the Medify MA-112 as the best Medify air purifier like I have?

The MA-112 circulates the air in a 2,400 square feet room 2 times every hour. And if placed in a 1,200 square feet room, it does 4 circulates every hour. In a room measuring 600 sq. ft., you’ll get 8 air changes every hour. Doesn’t that make the unit a great buy for your basement?

Unlike all other Medifys, this one uses two sets of filters. That translates into more comprehensive air filtration. It’s not surprising that its CADR is 950.

With a CADR of 950, this thing pushes out an insane amount of sanitized air on the highest setting. But even on medium and low, you’ll still get enough power. Most users prefer leaving it on auto. And at bedtime, you’ll want to select the sleep mode so you can sleep as deeply as a baby.

Its modern, easy-to-use touchscreen control panel makes utilizing this purifier a breeze. There’s even a programmable timer. This feature lets you turn it off automatically after a predetermined amount of time. You can time it to shut off after 1, 2, 4 or 8 hours.

You’ll  also love that the MA-112 generates real-time air quality reports. You get actual PM2.5 numbers. In addition, the overall air quality situation displays as a distinct color.

Finally, it comes with a child safety lock so your children won’t mess up with the settings.

Overall, the Medify MA-112 is a terrific air purifier that cleans the air efficiently and effectively. It’s powerful and fast.  But it’s pricey. However, the price seems reasonable enough.

Whether your main concern is nasty allergies, mold, VOCs, toxic fumes, MJ smoke or wildfire smoke, grab the Medify MA-14 HEPA GRADE H13.  You’ll love it. Check it out on Amazon.
