Airthereal Reviews

Last Updated on

Do Airthereal air purifiers do the job? Are they worth it? How do they work? Are replacement filters affordable? Do they use UV-C technology or ionize the air? Do they produce ozone? What filtration technology (ies) do they use? What’s the best Airthereal air purifier on the market today? As I researched for and prepared these Airthereal reviews, I kept all these questions in mind.

Want to go straight to Amazon and read customers’ Airthereal reviews?  Well, why not?

My goal here is to help you become a smarter shopper. I envision a better informed you. I see someone who can decide without hesitation whether Airthereal air cleaning devices are a good bet.

Who Manufactures Airthereal Air Purifiers?


Airthereal, a medium-sized company based out in Las Vegas, Nevada, makes these air cleaning devices. It’s an American company, a business that needs your and my support.

Founded in 2017, it’s pretty young. Doesn’t that mean it lacks the experience bigger, older companies have? Well, not really. The founders boast years of experience earned working in the air purification industry. And the company’s engineers are as good as any.

I also noticed that these air purifiers are sold pretty much everywhere. They’re on Amazon, Walmart, and other places. They’re also selling them on the company’s website. That convinced me that they’re a serious and financially stable business. You needn’t worry that they might disappear suddenly, leaving you with an air purifier you can’t use. Because you can’t find replacement filters.

When I contacted Airthereal for some information about their products, I noted something I’ll share with you. Not that I think it’s particularly important, though. But I noted that some of customer service reps didn’t speak very good English.

At least, 2 of them certainly didn’t sound like native-English speakers. It felt like they struggled with answering some of my questions. Luckily, I finally got connected with someone who finally provided all the info I needed. Maybe they should have more English-proficient people at customer support.


How Many Options Does Airthereal Offer?


The company (as of this writing) has 3 models available on the market. All of these air purifiers are relatively new in the market, and they’re quite affordable. You would find thousands of reviews on them, but there are reviews to help you along. You can read airthereal air purifiers reviews on Amazon now.

The 3 options include the following:


  1. Airthereal APH260 Pure Morning 7-in-1


  1. Airthereal ADH80 Day Dawning (7-in-1)


  1. Airthereal Day Dawning ADH50B (7-in-1)


Important: For some reason, Amazon sells these air purifiers at a lower price than the manufacturer. Do I need to encourage you to buy from Amazon as opposed to the company’s website?


How Do Airthereal Air Purifiers Work?


All Airthereal air purifiers feature a compact filter cartridge. You get all the filtration benefits in one easy-to-insert package. Each cartridge has a prefilter, a 5-in-1 activated carbon filter, and a True HEPA filter. The activated carbon filter is a combination of 5 different filters.

These 5 filters include an activated carbon filter, Nano Mineral filter, Cold Catalyst filter, Photo Catalyst filter, and a Molecular Sieve. This filter is superior to regular odor removers in many ways owning to the additional filtration layers. It offers more comprehensive filtration than what you’d get from a regular activated carbon filter.

The APH260 pulls air from two vents, each on either side. It then cleans it and sends it out via the top. By comparison, the ADH80 exerts a 360-degree pull on the air, sanitizes it, and blows it out via the top. It’s a cylindrical design, and that’s how such designs typically work.

Finally, we have the ADH50B. Even though the design isn’t cylindrical, the unit sucks dirty air in from all sides. Once purified, the air is forced out via the top.

Note: the filter for this air purifier is only accessible from the unit’s bottom rather than the front or back. But wouldn’t you expect better air circulation from such a design?

As you have seen, all these devices push treated air out via the top. And that’s a good thing. It means you can place them pretty much anywhere in the room. Still, it’d be advisable to place them in a location that promotes better circulation.


Airthereal Air Purifiers Offer 7 Stages of Filtration


All 3 air purifiers offer multi-stage filtration. I imagine that more filtration stages means better filtration. But I’m not saying only buy devices with the highest number of filtration stages. In fact, some of the most powerful air purifiers I’ve seen offer no more than 3 stages of filtration. A good example is Medify air purifiers.


ALL Airthereal Air Purifiers are CARB and ETL-rated


Being CARB-rated is critical when it comes to choosing a safe air purifier for your home. A CARB-rated device ships to California. In addition, such a product pushes out ozone levels whose concentration never surpasses 0.05 ppm.

The APH260 became CARB-certified on 16th October, 2018. The ADH80 earned its certification on 19th August, 2019 while the ADH50B got it on 5th September, 2019.

All of these air cleaners are also ETL certified. The APH260 is also FCC & CE-certified.

But what do these certifications mean?

Let’s start with FCC. The U.S. Federal Communications Commission wants companies to make electronic devices whose electromagnetic interference (EMI) stays within certain limits. An air purifier that’s FCC-certified won’t interfere with other appliances placed in close range. Note that Only the APH260 is FCC-certified.

An ETL-certified product is one that’s been tested by the nationally recognized testing lab, Intertek and ETL Semko. Such a product (air purifier in this case) may bear one of the following identifiers:


US & C: This identifier means that the item complies fully with the safety standards favored by UL and CSA. UL stands for Underwriters Laboratories Inc. while CSA is an abbreviation for Canadian Standards Association. Both UL and CSA are nonprofits that focus on testing products for safety.

US: A product bearing this identifier ONLY has only complied with the safety standards spelled out by UL.


C: If a product bears this mark ONLY, understand that it’s fully compliant with CSA standards (only).


What about CE certification? A product that’s CE-certified can be sold in any country within the European Union.  Such a product has met all the mandatory safety and health requirements spelled out in relevant EU directives.


Are Airthereal Replacement Filters Expensive?


No, they’re quite affordable.

Of all 3 Airthereal options, the APH260 has the most expensive filter, costs around $30 for the single pack. If you go with the 2-pack option, you’ll save around $10. And that’s a really good deal. You can get the 2-pack deal for around $50.

For the ADH80, the single pack’s cost stands at around $ 20 while the 2-pack deal costs around $36, letting you keep $4 every year.

Finally, we have the ADH50B whose single pack offer costs around $16. It didn’t seem like Amazon or the manufacturer carried a 2-pack for this one. Buying 2 of these would set you back about $32 annually, which seems reasonable to me.

As you’ve seen, the smarter thing to do is to buy the 2-pack 7-in-1 filter rather than the single pack filter. Not only will you save money, but you’ll also save time since you’ll shop only once a year.

Please Note that prices keep changing, and the amounts shown here are ONLY correct as of this writing.

What Do the Running costs Look Like?


As you’ve noted, replacement filters for these air purifiers don’t cost an arm and a leg. And that’s good news because the running costs for these devices stay where you want them, that is, down there. Even when you factor in the initial cost and power cost, none of these machines is too expensive to own.

If you buy these things and keep for 3 years, here’s what the overall costs would look like:


APH260: {Unit Cost + (Filter Costs + Electric bills) x 5}

{$111 + ($60 + $43.80) x 5}

= $630 in 5 years or $126 per year.


ADH80:   {Unit Cost + (Filter Costs + Electric bills) x 5 }

{$80 + ($40 + $17.52) x 5 }

=$367.60 over 5 years or $73.52 each year


ADH50B:  {Unit Cost + (Filter Costs + Electric bills) x 3 }

{$50 + ($32 + $3) x 5}

= $225 over 5 years or $45 every year.


Evidently, it’s comfortably affordable to own and run Airthereal air purifiers.




Note 1: The first option’s energy consumption is about 50W, the second one about 20 W, and the third one around 3.5 W.

Note 2: It’s assumed that you’d be paying 10 cents per kWh drawn.

Note 3: It’s assumed that you’ll run your unit 24/7/365, which is what’s recommended especially for those with respiratory illnesses. Or those with breathing challenges.

Note 4: The prices used for the calculations above are ONLY applicable as of 03.11.2019. Please insert the actual costs in case they’ll have changed by the time you get to read this post.



  • Affordable: the cheapest Airthereal is super affordable
  • 7-stage filtration = very thorough filtration
  • They purify the air down to 0.1 microns
  • Ideal for allergy and asthma
  • Look cute
  • Don’t take up much space
  • The largest Airthereal consumes just 50W
  • All are CARB and ETL certified
  • Portable



  • Filters aren’t the cheapest but still affordable
  • The APH260 produces ozone
  • The ADH80 &ADH50B clean very small spaces


As you can see, these air purifiers aren’t perfect. But they do the job. These products are some of the newest entrants into the air purification market. And that does mean something. Airthereal’s engineers have had many powerful existing filtration technologies and engineering designs to tinker with before creating these products.

Not surprisingly, very few air purifiers, especially those with True HEPA filters, offer 0.1-micron filtration. And that’s a huge difference between these devices and other brands.

Plus, they’re super affordable, with the largest and best airthereal air purifier retailing at under $115 (*as of this writing). Please note that prices keep changing, and what may be correct price now may be incorrect the next minute. So, keep that in mind as you read these Airthereal reviews.

Airthereal Reviews


Let’s roll.


1. The Airthereal APH260 7-in-1 Review



This air purifier is a great solution for odors, VOCs, smoke, dust, and more. That makes a great option for asthma and allergy sufferers.


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


Price: Under $115 as of 03/11/2019


Coverage: 355 sq. ft.

Weight: 10.4 lbs

Dimension: 13″ x 6.7″ W x 21.2″ H

CADR: 152

Filter Life: 6-8 months

Power consumption: 50W max

Warranty: 2-year limited


The APH260 is a mid-range air purifier that offers 7-stage filtration. It uses a True HEPA filter, and that’s great. With this unit, up to 99.97% of indoor air pollutants 0.1 microns in diameter or larger won’t bother you anymore.

Unfiltered air enters the device from two vents. One of the vents is on the right side and the other one on the left side of the unit. See the vents on the pic above.

If you install and operate this machine 24/7 for a day or two, you’ll see much less indoor air pollution.  You’ll have much less dust, pollen, pet dander, mold spores, bacteria, and more.


How the APH260 Works


How the APH260 Works

Look at how the thing does the job.


Basically, you’ll stop fretting over PM2.5 and PM10 particulates. There’s a table in this air purifier buying guide that lists more than 20 particles and their sizes in microns. Check it out to know all the particles this machine might help you eradicate.

And if you smoke, odors, and VOCs are a problem in your home, the unit’s improved activated filter has got you covered. This is a 5-in-1 activated carbon filter that’ll help you drastically reduce gaseous pollution. This activated carbon filter comes attached to a Nano Mineral filter, a Cold Catalyst filter, and a Photo Catalyst filter. In addition to these, there’s a molecular sieve.

Together, these filters, the True HEPA, and the prefilter purify the air down to 0.1 microns. Anyone who values cleaner, fresher air will want to try out this option.

Look at its filters

APH260 Filter-1 PACK

You can buy the 1-pack option above or the 2-pack option below. It’s large surface area filter so you can breathe the purest air possible. 


APH260 Filter-2 PACK

Buy the 2-pack option and forget about replacement filters for a whole year.


But does the APH260 kill germs and mold? Yes, it does. The unit offers UV-C filtration along with an ionizer. The UV-C light combats microbes including mold spores, viruses, and bacteria. The technology works by changing the DNA structure of these microbes, which makes them completely harmless.

And don’t worry — the UV light won’t harm you. The manufacturer has taken steps to ensure users stay safe from UV radiation.

The unit’s ionizer spews out anions that combine with positively charged ions, forming larger, heavier particles. The neutralized particles are then captured by the other filters. That leaves your indoor air feeling noticeably cleaner and healthier than ever. The UV-C and ionizer can be effortlessly accessed on the unit’s sleek, easy-tap control panel.


Here’s How the Control Panel Looks Like

Control panel APH260

It’s a clean, easy-to-use control panel with clearly indicated buttons.


Although the control panel features several options, it’s not finicky.

With the APH260’s automatic mode, operating the unit is easy and convenient. It’s basically a set-it-and-forget-it feature.

When on auto mode, the thing knows when it needs to take action to restore your room to safe air quality levels. What’s better than that? Nothing!

There’s also a PM2.5 counter that displays numbers indicating the room’s actual air quality. Most air purifiers that feature a particle sensor show the room’s air quality in terms of colors rather than actual numbers. I see that as a clear advantage the unit has over many of its competitors.

And if you choose the unit’s sleep mode, your device switches to the lowest of 3 fan speeds. Once you select that option, you’ll sleep without disturbance.

Note: the PM2.5 sensor doubles up as the filter change reminder. When the time comes, the sensor lights up and flashes continuously until you take action.

After replacing the filter, you should reset it. To reset the timer, presshold the fan speed and timer buttons for about 3 seconds.

What about the UV-C light bulb? When should it be replaced? It’s supposed to last 5 years. However, you can always change it before then if its effectiveness diminishes substantially.

In addition, there’s a 12-hour programmable timer. You can easily input auto shutoff instructions to save energy.

What about its noise levels?


On low, the unit is almost inaudible — about 28 dB. But on speed 3, the noise can be as much as 49 dB, which is not crazy-loud. Still, you won’t want to choose this speed for bedtime. Select the sleep mode, instead.

What about power consumption? The unit consumes 50W max. That’s not much. The typical laptop consumes about the same amount of power. That’s about 438 kWh per year or about $43.80.

What filter does the APH260 use? Is the filter expensive? The filter (1 pack) goes for about $30 (as of this writing). And since you’ll change it semiannually, you’ll fork over about $60 annually. Reasonable filter costs if you ask me.

The APH260 is ideal for those terrible odors wafting out of your cat’s litter box. It’s also great for tobacco smoke and wildfire smoke as well as VOCs such as cooking smells. While I can’t say it’s the #1 solution for horrible smells, it’s accurate to say it does a pretty good job.




  • UV-C kills germs and microbes
  • Light + portable
  • Under $115
  • Filters down to 0.1 microns
  • Enhanced odor removal filter
  • 12-hour timer
  • CADR-rated
  • CARB-certified, ETL, FCC &CE certified



  • Produces ozone
  • Not ideal for large rooms


Even though the unit produces ozone, it’s CARB-certified. It ships to California — it’s safe. But my opinion is that people with asthma should keep the ionizer and UV-light turned off. Or buy a different option altogether.

But I have a little issue with the recommended coverage area. I noticed that the unit’s CADR is 152, and it’s meant to clean up to 355 sq. ft.

Well, I’m not sure the thing will work effectively for a room that big.

But what informs my doubts? AHAM’s 2/3 Rule, that’s what. According to AHAM’s 2/3 rule, an air purifier with a CADR of 152 is best suited for rooms measuring about 228 square feet.

My advice: Buy this unit to purify no more than 250 square feet.


2. Airthereal ADH80 Day Dawning HEPA (7-in-1) Review

Choose this for treating the air in your car. It comes with a car adapter that boosts ease of use.


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


Price: Under $100 as of 03/11/2019

Coverage: 160 sq. ft.

Weight: 4.8 lbs

Dimension: 7.1″ D x 7.1″ W x 11.7″ H

CADR: 47

Filter Life: 6-8 months

Power consumption: 20W max

Warranty: 2-year limited


The Airthereal ADH80 Day Dawning is a small-room air purifier. It’s CFM (Cubic Feet Per Minute) is just 47. It’s the sort of device you want on your desk at work or in a smaller than average bedroom. I assume the average small bedroom in the U.S. has a square footage of 110.

It’d also be a great buy for your car. With it humming in the car, you’ll see considerably less car exhaust. Unfortunately, the unit is too small to remove traffic pollution in a large room. You may want to check out these 5 best air purifiers for exhaust fumes. It comes with a 12V adapter so you can effortlessly plug it in and start sanitizing the air in your car. You’ll love traveling more.


Here’s How the ADH80 Works


how the ADH80 works

See this air cleaning device at work.


Even though the manufacturer says it should clean up to 160 square foot, I have a different opinion on that. Going by AHAM’s rule, this unit is best for a room measuring about 9 x 8 feet or about 72 sq. ft. That’s about the average small bedroom size in the U.K.

It’s cylindrical in design, and it stands only 11.7.” As you can see, it’s nowhere near being bulky. Also, it features a 360-degree air inlet, which allows flexibility in relation to where to place it.

As noted above, the filter can only be accessed from the unit’s bottom area. Positioning the filter there leaves every side free to do what the thing is meant for: letting in unfiltered air. And like all Airthereal air cleaning devices, this one lets treated air out via the top.

Like its larger sibling, the APH260, the ADH80 offers multi-stage air filtration. Air passes through 7 stages before it returns to the room cleaner and fresher. It’s a single filter made up of several layers of different filters that perform different roles.


Replacement Filters for the ADH80


ADH80 Filter-1 Pack

It’s easy to replace and offers multi-level air filtration.

ADH80 Filter-2 Packs

Buy this 2-pack filter for your ADH80, and that’s a year’s worth of purified air..


The prelim filter (prefilter) exists to capture course particles such as fibers and pet hair. The True HEPA filter follows next. And it removes fine particles such as pollen, pet dander, mold spores, dust, pollen, and more.

The last filter is the powerful 5-in-1 activated filter. It contains a carbon filter, a Nano Mineral filter, a Cold Catalyst filter, a Photo Catalyst, and a molecular sieve. These five filters are there to neutralize smells and VOCs. If you have this little purifier in your car, you probably won’t need to use an air freshener.

But unlike the APH260, this unit doesn’t display air pollution in numbers. Instead, you’ll see 4 different colors. Each color represents a particular air quality situation. If the air quality is good, the color displayed is green, and if ok, the color is yellow. And when bad, the color displayed is red. Finally, there’s blue for when the air quality is very bad. To use the air quality sensor, you MUST leave the little device to operate on auto.

It also features an auto timer allowing the user to choose 2-hour, 4-hour, or an 8-hour duration.


Here’s its control panel


ADH80 conttrol

Its control panel sits on the top, and it displays the current air quality using 4 different colors: Green, Yellow, Red, and Blue: Good, ok, bad, very bad.

Noise Levels


When on sleep mode, the unit produces just 22 decibels. And that’s pretty quiet. Even the lightest sleeper should have no trouble falling asleep.

As to power usage, the unit comes rated for 20 W max. If you ran the thing 24/7/365, it’d consume roughly 175.2 kWh, which works out to just $17.52. That’s quite economical. But you won’t want to use this air purifier unless your room is very small. Or unless you’re mainly interested in addressing car exhaust inside of your car.




  • Comes with a child lock
  • Extremely light
  • Very quiet
  • Nice-looking
  • Under $100 (as of 03.11.2019) on Amazon
  • CARB and ETL certified
  • Car adapter so you can purify your car
  • Timer: 2,4,8 hours




  • Purifies a small area
  • Cleans a much smaller area than indicated
  • Not FCC and CE certified


There’s a reason I’ve given the ADH80 a rating of 3.5. I’m not sure it’s as great as some other air purifiers I’ve seen in that price range. Actually, one or two people said they didn’t think the little thing did anything for them.

That said, majority of users seemed quite satisfied with their device.


3. Airthereal Day Dawning ADH50B 7-in-1 (Under $50)


Pick this for purifying your cubicle at work. It’s small, super light, and cute.


Editor’s Rating: 4 out of 5 stars (4 / 5)


Price: Under $50 (As of 03.10.2019)


Coverage: 110 sq. ft.

Weight: 2.5 lbs

Dimension: 6.3″ D x 6.3″ W x 10.2″ H

CADR: 30

Warranty: 2-year limited

Filter Life: 6-8 months

Power consumption: 3.5 max


Finally, let’s take a look at the ADH50B. This is the smallest of all 3 Airthereal air purifiers. It’s also the lightest, shortest, and quietest. In addition, it offers the least CFM (just 30).

The manufacturer recommends that the unit be used for treating rooms with a square footage of 110 or smaller. But in my opinion, this is not what you need for 110 square feet rooms.

AHAM’s 2/3 rule suggests that this small purifier is best suited for areas not larger than 45 square feet. Now, that’s a very small area. Much smaller than what would be considered a small bedroom. That’s about 8 ft. x 6 ft. I think the ADH50B would work best if used to purify the standard cubicle (48 square feet).

The unit offers 7-stage filtration just like its 2 larger siblings. There’s a prefilter for capturing large particles, a True HEPA filter for fine particles, and a 5-in-1 odor-removing filter. It should filter the air down to 0.1 microns just the other 2.

ADH50B Filter

This is how the filter for the ADH50B looks like. Looks pretty much like the one for its sibling the ADH80.


I expected that the ADH50B wouldn’t offer more than basic features. And it didn’t disappoint. It comes without an air quality sensor. It also lacks a PM2.5 particle sensor, and there’s no auto mode. One more thing, it has no timer with this choice. But at that price, one can’t justifiably complain that the unit lacks these options.

Good news: the unit offers a night mode and a filter replacement indicator. I’ve come across many comparable alternatives that don’t have these features. And it purifies the air, which is what matters most.

On the lowest setting, the noise hovers around 22 decibels. Simply launch the sleep mode, and your unit will automatically operate at the lowest fan speed. At the highest fan speed, the noise never goes past 40 decibels. It’s possible to sleep through that level of noise. But if you’re a very light sleeper, you’re better off with the sleep mode.

The control panel for the unit sits on the top, just like it does for the APH260 and ADH80. The panel is very simple and easy to use, featuring only 3 buttons. These are the power button, the sleep mode, and the fan speed button.

When you select the power button, you’ll see a blue ring light up on the unit’s side near the top. The same goes for when you choose the night mode — a small blue bead lights up next to the power button.


See the control Panel of the ADH50B



This is the control panel for the air cleaning device above. It features only 3 buttons; operating it is a breeze.


This air purifier features a 360-degree air intake. And it you’ll always love how awesome it looks. It’s a two-color design: the lower part that features the inlet is silver while the upper part is beautifully black. One look at this device and you’ll think it’s a smaller, cuter version of the Blue Air 211+.

Filters last about 6 months, and a built-in indicator lights up so you won’t forget to replace them.

When it comes to power consumption, this unit needs 3.5W max. That adds up to about 30.66 kWh. Assuming an energy cost rate of 0.1 cent per KWh, you’ll pay just $3 dollars annually!

Believe it or not, I’ve never reviewed an air purifier whose energy costs were that low. The downside, though, is that the area purified is very small.


How the ADH50B Works


ADH50B works like this

Can you see that the filter is inserted at the bottom side of this air purifier? It fits snugly so you won’t have unfiltered air passing through and coming out untreated.




  • Extremely light
  • Consumes just 3.5 W of power
  • Inexpensive
  • 360-degree air intake
  • A sleek, cute design
  • A 3-button control panel
  • Super quiet especially on low
  • CARB & ETL-certified




  • Purifies an extremely small area
  • Lacks particle sensor
  • No air quality display
  • No smart auto mode


No one should be surprised that this unit lacks these smart features. At that price, that’s expected. My only gripe is that the unit cleans a very small area in reality. Ignore what the manufacturer says when it comes to coverage.

I’d recommend this unit for cleaning cubicles rather than small bedrooms and other larger spaces. Good thing is it works. You’d notice a difference in a day or so if you left humming away 24/7. It consumes a very little amount of energy — no mounting bills to worry about.


Airthereal Reviews: Overall Winner


So, which is the best Airthereal air purifier? The APH260 Pure Morning emerged as the clear winner.

First off, its CFM of 152 is significantly larger than that of its two smaller siblings. Second, it features an easy to replace 7-in-1 filter that includes a True HEPA filter. Thanks to this filter, the unit does a great job of removing particles down to the 0.1 micron range.

Third, there’s an ionizer that freshens the air. In addition, there’s a long-lasting UV-C light bulb for decimating disease-causing microbes.

Fourth, it offers a quiet night mode, a PM2.5 counter, an auto mode, and a 12-hour auto off timer.

Finally, the Airthereal APH260 Pure Morning 7-in-1 has bagged 4 important health and safety-related certifications while its siblings have only 2. It’s CARB, CE, FCC, and ETL-certified while its smaller and less powerful siblings boast only CARB and ETL certifications. Clearly, this option trumps its two contenders for the top spot.

The only issue I have with the APH260 is that it won’t clean the manufacturer-recommended 355 square feet. Expect no more than 250 square feet coverage. But that seems like a reasonable coverage area for the price.

But if you seek something to keep your car smelling clean as you drive to work or wherever, pick the ADH80. You can also choose this for a very small bedroom.

And for treating your cubicle at work, go for the ADH50B.
