7 Best Air Purifiers with Washable Filters:


Here they are. And please note that the list isn’t organized in any particular order.

1.Pure Enrichment PureZone 3-in-1 Review


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


Why do I believe the Pure Enrichment PureZone 3-in-1 is one of the best air purifiers that use washable filters? First off, you’ll love the way it kicks out air pollutants from your office, bedroom, or kitchen. Its coverage is 200 square feet or roughly 15″ x 13.” That’s small room, and it’ll purify it really well.

What about the unit’s general appearance? I’d not say it looks amazing. However, it looks much better than the comparable Honeywell HPA100.

The air purifier eliminates 99 percent of pollen, odors, household dust, pet dander, mold spores, and more. And since it also features UV-Light filtration, it kills microbial organisms including germs, viruses, bacteria, and fungi. It’s the kind of companion you’ll want when flu and allergy seasons come around.

A friend of mine who battles terrible allergic reactions can’t live without her Pure Enrichment PureZone 3-in-1. She’s noticed a dramatic improvement in the symptoms. That’s why she’s vowed to replace the unit with itself should it ever break down.

It’s easy to set up. It’s a 5-minute job. And it’s one of the quietest 3-speed washable-filter air purifiers I’ve ever researched. On low, the sound is almost inaudible. On the other 2 speeds, you have peaceful white noise. It’s like beautiful “soft” music that lulls you to sleep after a hard day at the office.

The HEPA filter requires replacement every 6 months. Good thing is they’re available and affordable. So, how is the Pure Enrichment PureZone 3-in-1 a washable-filter air purifier? It’s because the prefilter is washable. The prefilter is an integral part of the unit’s 3-in-1 HEPA filter. You should remove it and vacuum it. Alternatively, you may wash with soap and water.




  • Easy to maintain
  • Kills viruses, bacteria, and mold
  • Auto shutoff timer (2,4,8 hours)
  • Affordable
  • Filter-change light
  • Small & Portable
  • Intuitive control panel
  • Quiet on low
  • White noise on medium + high
  • Very few unhappy users




  • Washing the prefilter can’t be fun
  • Ozone produced
  • Prefilter doesn’t last long


If you’re asthmatic, turn off the UV-C light mode. Ozone is a known irritant, you know. The prefilter is made of felt-like material. It’s built into the 3-in-1 HEPA filter and should be removed and washed separately. It’s easy to tear it as you detach it from the HEPA one. Actually, you shouldn’t expect it to last more than a few washes. It’s best to just change the prefilter as you replace the HEPA one.

Good news: the replacement filter is quite affordable. It’s considerably cheaper than many other comparable replacement filters I’ve seen. Still, the manufacturer should improve the prefilter so it stops getting torn when removing it to wash it.




5 years. That’s much longer than I’ve seen with many other options.


2.Honeywell 50250-S Review


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


A cylindrical air purifier weighing 21.2 lbs, the Honeywell 50250-S looks somewhat bulky. However, it’s quite easy to transport around the house. It’s not cute or whatever, but it does the job. Also, the install is super easy. You won’t need any tools. Just your hands.

The unit leverages a special technology called SurroundSeal. The technology ensures that no untreated air ever exits your air purifier. The device uses a powerful motor that sucks in dirty air from all directions. Even if you place it against the wall, it’ll still work superbly. Once it’s purified the air, the motor exhales it via the top.

It’s designed to clean medium-sized rooms and large spaces up to 390 sq. ft. In an enclosed space of 390 sq. ft., the air purifier operates at an impressive ACH of 5. That is, it circulates the air 5 times within 60 minutes running on its highest speed. In a smaller room, say 80 square feet, this portable air cleaner has a considerably higher ACH. It’s been shown to circulate the air up to 23 times per hour.

The Honeywell 50250-S spews out a wide range of microscopic air pollutants. Its washable HEPA filter handles pet dander, mold spores, bacteria, household dust, pollen, and more. All these particles range between 0.3 to 100 microns in size. The device is tested and proven to remove air pollutants down to 0.3 microns.

Although the manufacturer says it removes viruses, I’m not sure I agree with them fully. Viruses are in the range of 0.005 to 0.3 microns in diameter. The machine certainly can’t remove any viruses that are smaller than 0.3 microns. It’d only eliminate those viruses whose diameter is equal to or exceeds 0.3 microns.

But does the Honeywell 50250-S remove smoke? Yes, but you won’t get 100 percent thoroughness. That’s because smoke particles are in the 0.01 – 4 microns range. Any smoke particles equal to or larger than 0.3 microns will get sucked out of your indoor air.

How long does the washable filter for the Honeywell 50250-S last? It lasts roughly 3-5 years when you’re running the thing 24/7. It’s not a permanent filter. You’ll have to replace it at some point. Regarding the prefilter, you should get rid of it every 3 months.

How long should I run the Honeywell 50250-S? Run it 24/7 if you have asthma or contend with allergies. But if you just crave cleaner, healthier air, you can operate it only when you’re at home.




  • Draws in air from all directions
  • Pushes air out the top in all directions
  • Compact, stable design
  • SurroundSeal technology minimizes air leakage
  • Filter-change indicator
  • Users love it
  • Long-life HEPA filter
  • No rattling noises
  • Filter replacement a breeze




  • White — no variety
  • Relatively expensive
  • Won’t remove viruses and gases perfectly
  • Prefilter replaced every 3 months
  • Too much LED display light
  • Washing HEPA filter not enjoyable
  • No indicator for filter cleaning


Few air purifiers remove smaller-than-0.3-micron particles, and the Honeywell 50250-S is no exception. Also, and not surprisingly, they’re not excellent when it comes to eliminating gaseous pollutants.

I’ve also found that this air cleaner’s blue LED display light might disturb light sleepers. But placing a cover of sorts should sort out the problem.




5-year limited warranty. I like this, and I think you will, too.

3. Winix 5500-2 (3-Stage Air Purification) Review


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


The Winix 5500-2 is another one of the best air purifiers that use washable filters. This portable room air cleaner is AHAM-tested and verified. It’s been subjected to a number of tough engineering tests and has endured. You’re getting a product that’s endorsed by experts and trusted by many, many discerning consumers.

Well, some people might say that the Winix 5500-2 is an eyesore. I can’t blame them. But while it doesn’t look terrific, it’s not particularly ugly either.




Winix 5500-2 uses 3 filters. The first one is the prefilter. You encounter the filter upon removing the front panel. The prefilter for the Winix 5500-2 is permanent. In other words, you need not replace it. However, the manufacturer says to wash it every 2 weeks. The filter captures larger contaminants and reduces odor.

The second filter (middle filter) is the Advanced Odor Control filter. It’s a carbon filter and protects you against pet odors, kitchen odors, smoke, and VOCs. The AOC is washable. It can help you save a bundle in the final analysis.

The third filter is the HEPA filter which captures 99.97 percent of a set of airborne allergens. It delivers peace-of-mind by removing smoke, dust, pet dander, mold spores, pollen, and even microbial organisms such as bacteria. But this filter needs regular replacement. Make sure to check the indicator so you can change it when the time comes.


The PlasmaWave Technology


How does the PlasmaWave Technology work? This technology works pretty much like an ionizer. However, there’s a clear difference between how the PlasmaWave Technology and ionization work.

While ionizers only produce negation ions (anions), this technology pumps out both anions and cations. It reduces the amount of static electricity in indoor particles by neutralizing their charge. After that, these neutral particles are sucked into the air purifier’s air flow and eliminated. The PlasmaWave technology slows down mold grow rate while reducing odors and smoke.

In addition, the technology also addresses viruses. Yonsei University tested the PlasmaWave Technology and found interesting results. According to the university, the technology decimates live influenza virus by up to 99.6 percent in just one hour.


But Is the PlasmaWave Technology Safe?


Yes, it is. Admittedly, though, the Winix 5500-2 releases ozone into your indoor environment. However, the amounts emitted aren’t excessive. The air purifier is CARB-certified. It’s proven to generate ozone quantities that stay within what “strict California” considers to be safe limits.

The emissions are well below the state’s Air Resource Board’s safety standard for ozone. The standard requires ozone levels to stay below 50 parts per million levels (ppm).


Smart Sensor


Lest I forget, this air purifier uses a smart air quality sensor. The sensor’s job is to monitor your indoor air quality. If your air is dirty, the sensor authorizes the air purifier to spring into action to sanitize it.

Note 1: place the Winix 5500-2 at least 18 inches away from the TV, radio, and other electronics. That’s because these electronics emit electromagnetic waves. And these waves will cause your air purifier to malfunction.

Note 2: Can I wash the HEPA filter for the Winix 5500-2? No, don’t do that. It’s not washable. Instead, make sure to replace it every 12 months.

Note 3: Can I wash the AOC carbon filter? Yes, wash it once every 3 months. Also, replace it every 12 months.




  • PlasmaWave Technology
  • 2 Washable filters
  • Durable
  • Highly effective
  • Smart sensor for air quality control
  • Affordable
  • Easy to carry and install
  • Comes with remote control
  • Easy to use control panel
  • Filter replacement light




  • HEPA filter requires replacement
  • AOC not a permanent filter
  • Bad smells
  • Annoying noise
  • No color options (only black)



Bad smells are sometimes noticeable for a couple days after the install. If the smell continues, chances are that the AOC filter needs replacement. But there’s another possible explanation. Maybe you’ve placed your Winix 5500-2 in an area with too much dust, odors, or smoke. At least, that’s the explanation Winix have offered.

But what’s causing my Winix 5500-2 to vibrate and rattle? You’ve likely placed it on a surface that’s uneven or slanting. Solution: Always place this air purifier on a hard, level surface.




1-year limited warranty


4. Hathaspace Smart (6-in-1) Review


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


The Hathaspace Smart is one the more modern air purifiers on the market today. It’s a sleek design with an aerodynamic curvature that boosts air flow efficiency. The unit looks good, and it blends in perfectly with pretty much all kinds of décor.

But what contaminants does the Hathaspace Smart (6-in-1) remove? It helps eradicate dust mites, odors, smoke, VOCs, mold spores, pet dander, and pet hair. It filters your indoor air all the way down to 0.3 microns.


The Hathaspace Smart Features 6-Stage Filtration


The first filter is the Nano Cold Catalyst filter. The name may sound like something complicated, but it’s actually a regular prefilter. Its job is to eliminate pet dander, dust, ammonia, formaldehyde, and benzene. This prefilter removes more contaminants than most of the washable prefilters I’ve seen.

The second one is the Cellular Activated Carbon filter. This one helps reduce VOCs, odors, gaseous pollution, and smoke. The Third one is the Antibacterial filter. The filter contains nano materials designed to kill fungi, bacteria, and viruses.

The fourth one is the popular HEPA filter. The filter helps handle 99.97 percent of a category of air pollutants equal to or larger than 0.3 microns. These include pollen, dust, pet hair, and mold spores. The fifth filter is actually not a filter. It’s a 245-nm UV-C light that obliterates bacteria and viruses. The “filter” sterilizes viruses and bacteria, making them harmless. The UV light also helps you take care of smoke and mold.

Now, are the filters for the Hathaspace Smart washable? They should be, but the manufacturer says to just expose them to the Sun occasionally. The reason for that is to annihilate bacteria. That seems thoughtful to me. Still, I wonder what I’d do during cool seasons such as winter. Luckily, such seasons don’t last forever.


The Ionizer


Finally, there’s an ionizer that helps address stubborn odors. The ionizer works by neutralizing positively charged contaminants using negatively charged ions (anions).  So, does Hathaspace Smart pump out ozone? Yes, it does, and ozone can worsen asthma symptoms. Luckily, you can easily turn off the ionizer any time you want.


What’s the Purification Coverage of the Hathaspace Smart?


In my opinion, this air purifier won’t clean 350 sq. ft. well. Why? It’s because its ACH is 2 in an enclosed area of 350 sq. ft. at its highest speed. I’d expect more “vitality” from a machine of this size.

The manufacturer states that the Hathaspace Smart is designed for treating spaces as large as 350 sq. ft. These are medium-sized and large rooms. In an enclosed area that big (350 sq. ft.), the unit should replace the air 2 times on the highest fan speed.

Do you have asthma and your room is large (300 to 350 sq. ft.)? If yes, I advise you not to buy the Hathaspace Smart. People with breathing difficulties need air purifiers with an ACH of at least 4. But if your room is much smaller than 350 sq. ft., you can buy it.

I’ve figured out that this unit may not work well for rooms that are 350 sq. ft. in size. Given its CADR for smoke, pollen, and dust (160 for each), I imagine it’d work best for rooms not exceeding 250 sq. ft.

The device uses an advanced sensor that monitors the air quality in the room. If the air isn’t clean, the sensor instructs the machine to adjust its fan speed instantly. There are 3 air quality levels namely Green (good), amber (ok), and Red (bad).

What about noise levels of the Hathaspace Smart? On low, you get 18-decibel noise. On high, the noise never exceeds 43 decibels. Evidently, it’s a quiet machine.


Filter Replacement


The following 4 filters must be replaced every 6 to 9 months:


  • Nano Cold Catalyst filter (prefilter)
  • HEPA filter
  • Antibacterial filter
  • Carbon filter


When the time comes, you’ll need to buy a set of these 4 filters. But they’re not as expensive as you might imagine. In fact, the set is considerably cheaper than some single replacement filters used by certain models.




  • Reasonable price
  • High tech look
  • Eliminates bacteria and viruses
  • CB, CE,and RoHS-certified
  • Quiet
  • Portable
  • Ionizer optional
  • Auto shutoff timer (1-12 hours)
  • Long-lasting filters
  • Multi-stage air filtration
  • No need to wash the filters




  • Generates ozone
  • Filters (4 of them) must be replaced every 6 to 9 months
  • Relatively more expensive than many alternatives
  • Not Energy Certified
  • UV light must be replaced every 3 years
  • Exposing filters to the Sun demands time
  • Cleans smaller areas than manufacturer recommends


The air seems somewhat more expensive than some other pretty decent options. Still, I feel the consumer is getting real value for their money here.




Hathaspace covers this product with a 1-year warranty. You can also make it 2 years by registering with the company.

In addition, the unit offers a 60-day money-back guarantee. I like that. You’ll enjoy stress-free shopping. The company boldly advises consumers to return the product if it doesn’t help relieve asthma and allergy symptoms. If no noticeable changes are seen, simply send the item back.


5. Blue Pure 121 Review


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


The Blue Pure 121 uses 3 efficient filters designed to treat areas as large as 620 square feet. If you install the air purifier in an enclosed space of 620 square feet and run it on high, you’ll see an ACH of 5.

It’s made of durable ABS plastic and aluminum, and it’s long-lasting. It features 2 washable prefilters designed to deal with large particles including lint, pet hair, dust, and more. The prefilters come in two matching colors, blue and gray. Don’t like these colors? Good thing is you can buy other colors separately. That lets you choose a prefilter color that blends well with your room’s décor.

There’s also an Activated Carbon filter meant to remove 99% of a number of indoor air pollutants. These contaminants include wildfire smoke, kitchen odors, pet odors, pollen, pet dander, mold, dust, viruses, and bacteria.

Does the Blue Pure 121 remove PM2.5? Blueair have asserted that it does.


Blue Pure 121 Noise Levels


On high, the Blue Pure 121 is quite loud. But you’d still be able to hold a conversation without needing to raise your volume. On medium, you get a soothing, consistent white noise. And on low, the thing is super quiet. The beauty of it all is that it delivers great air filtration performance while on low. If you have asthma, though, you’ll want to run it on medium or high.




  • Filter replacement indicator
  • Air drawn in from all sides
  • Portable
  • Exceptional performance
  • Portable
  • Energy Star rated
  • Easy on the eye




  • No auto shutoff timer, VOC & particle sensors
  • Chemical odor
  • Relatively expensive
  • Prefilters need to be washed regularly
  • Filters are pricey


The Blue Pure 121’s Bad Smell


Some people have reported noticing a plastic odor upon setting up their Blue Pure 121. Is the smell toxic? Who knows, maybe it is. And that’s not a pleasant possibility.

As I researched the problem, I found that notifying the manufacturer of the issue helps. One user had the company send a new filter and the problem disappeared. Blueair explained that glue on the filter caused the bad plastic smell.


No Air Quality Sensor


In addition, the Blue Pure 121 doesn’t tell you how good or bad your air quality is. At that price, you’d think they’d include this useful feature.

But the thing sanitizes the air. And that’s what matters most. That said, that’s an addition I’d love to see in future improved versions of this device. However, it features a filter-change indicator so you won’t have to track replacement dates.


No Shutoff Timer


I also think they’d have included an auto shutoff timer. That’s pretty much the standard for air purifiers sold at that price. I think that’d be a bit of a bummer for people who don’t spend much time indoors. Who does?

What would happen if you went away for a month and forgot to power it off? You’d find the thing still humming and purifying the air when you came back. You’d also get a higher electric bill. But for some reason, many people seem to love this air purifier. That’s because it does the air purification satisfactorily.

Here’s one more thing. This air purifier’s replacement filters are relatively more expensive than most, but they’re quite effective. Well, these costs can really add up over the long term. But if you’re ok with forking out for quality replacement filters, go for this option. It works.

Here’s why I recommend the Blue Pure 121. One, it’s great at cleaning the air. Two, it’s easy on the eye. Three, it uses washable prefilters. Finally, it’s easy to install and maintain.




The Blue Pure 121 comes with a 1-year warranty and a 30-day money-back guarantee.

I like that you can extend the warranty to 2 years by registering with Blueair. I also love that they refund shipping charges should the unit be defective and you return it.


6. Honeywell QuietClean Compact Tower (HFD-010)


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


The HFD-010 is an S-shaped Honeywell that uses a patented ifD filter to exit up to 99% of ultrafine particles. It looks simple yet beautiful, and its control consists of nothing more than one knob. No finicky touchscreen, and you’ll never complain that your touch didn’t register or something like that.

It’s one of the most affordable (under $100 as of this date) air purifiers with permanent filters on the market today. Well, it lacks the “smartness” a growing number of people crave in an air purifier. But it works; it cleans the air.

And while it features a tower design, it’s not bulky. It stands just 17 inches, definitely not the tallest air purifier ever made. It’s also very light, weighing only 7 pounds. Moving with this one won’t be much of a hassle.

Small wonder this air purifier is insanely popular. It’s drawn hundreds of 4 and 5 stars, and its overall rating is 4.0. Doesn’t that say something about its potency? I guess it does.

This air purifying machine handles a whole range of contaminants. But its cleaning ability may vary depending on the impurity in question. For instance, the device is excellent at eliminating dust, pollen, and pet dander. But when it comes to smoke, it does an “ok” job. If what bothers you most is tobacco smoke or wildfire smoke, there are much better options. And while it helps with mold spores, it’s not the most perfect tool for the job. Nor is it great for tackling odors and VOCs.

Yes, I’ve read lots of glowing reviews left by happy asthma and allergy sufferers. Most praised the purifier for its usefulness as an allergen remover. But as someone who’s used and reviewed quite a few purifiers, I can tell you this isn’t the best choice for allergy and asthma.

What I like most about the HFD-010 is that it boasts a permanent filter. You’ll NEVER need to budget for replacement filters ever again! But you must be ready to clean the filter from time to time (more on this later).

Picking this option equates to choosing to save money in the long term. But you need to hear this: this air purifier can’t and won’t offer the same level of performance as a True HEPA purifier. That’s why lots of people choose True HEPA air purifiers even though they’ll replace filters forever.

Sure, the thing makes a difference in your air quality. And you’ll wake up with a less stuffy nose. But this isn’t the perfect choice for an asthma or allergy sufferer. For such people, True HEPA or medical grade filters are the best solutions. Also, don’t place this one in a large room and expect spectacular performance. You won;t see it. It’s suitable for very small offices and bedrooms.

Does the HFD-010 have an ionizer? Yes, it ionizes the air. And the ionizer isn’t optional. That’s another reason not to buy this one if you have asthma. An ionizer is a useful addition that makes your air feel cleaner and fresher. For healthy people who breathe without any challenges, an ionizer is a great-to-have feature.

And it shouldn’t harm you since this air purifier is CARB-rated. It cranks out no more than 0.05 ppm of ozone, and that’s the maximum level allowed by CARB. That means California residents can order this machine.

Pro Tip: NEVER buy a machine that doesn’t ship out to California if you have breathing difficulties.

I recommend this unit for healthy people who want to save money on filters. It’s ideal for people whose indoor air isn’t laden with odors, VOCs, and smoke.

Buy the Honeywell HFD-010 ONLY if your main concern is pet dander, dust, and pollen.

Note: the unit comes with only 2 speed levels. You’ll want to choose speed 2 if you want powerful filtration. The machine is pretty quiet because it uses an ifD filter. I mean ifD filters have been shown to be noticeably quieter than HEPA filters.

However, few users have heard clicking sounds inside the unit. I have found that the noise mostly comes from loose parts in the fan. If you’re the handy type, you can dismantle the machine and fix the problem. While this problem doesn’t seem to be happening to everyone, it happens. And it’s my job to ensure you’re aware of that.

Dear reader, I’m an affiliate marketer. And I love it when fans of this blog (people like you, that is) buy something on Amazon through my affiliate links. That’s how I keep this site running. BUT I’ll never conceal IMPORTANT product information from my readers just because I crave commission. NEVER!

I always say it as it is and call things exactly what they are. Believe it or not, some companies have contacted me complaining that I presented their product in negative light. But I owe no manufacturer positive reviews or something like that. My readers sustain this blog, and they’re the only reason I spend hours researching products. They’re the boss, and they’re who I want to please.

Now that we’ve got that outta way, let’s look at the pros and cons of the HFD-010.




  • Attractive price: Under $100 (as of this writing)
  • Sturdy
  • You’ll never buy filters
  • Doesn’t take up much space
  • One-knob operation, not finicky
  • CARB-rated
  • Portable and not bulky
  • 5-year warranty



  • Releases ozone
  • Not ideal for allergy and asthma sufferers
  • Ionizer not optional
  • Only 2 speed levels
  • Oily substance on the front vents + chemical smell


It’s CARB-rated, though. So, the ozone issue shouldn’t worry you if you’re healthy. But I don’t like the ionizer because it isn’t optional. What if you don’t want to breathe ozone the whole time?

Some users have also noticed a greenish-yellow, oily substance on the front vents. Quite frankly, this is an issue that’s been noted by more than 3 users on Amazon. Well, use a cotton swab to clean out the oil leak. But could this be an indication that the motor inside has issues?

Luckily, the oil leak issue isn’t a widespread issue. Many users love this Honeywell, and they can’t imagine starting to pay for oppressively expensive filters.


oil leak HFD-010

A few users have seen oil leaking through the front vents, and it appears to be greenish-yellow. That’s not happening to everyone, though.


In addition, a number of users have  noticed a strong chemical or electrical odor upon opening the box and even after installing it. Luckily, the smell resolves after a couple days in most cases. Smells aren’t uncommon with new appliances, though.


7. Honeywell Washable Filter (HFD-120-Q) Review (Winner)


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


The HFD-120-Q is an appreciable improvement of its smaller sibling, the HFD-010. Like the HFD-010, it comes in a tower design. One great thing about a tower design is that allows for a larger air intake than shorter designs do.

Compared to the HFD-010, the HFD-120-Q is almost 2 times heavier (12.32 lbs). Still, it’s light enough to move around the house. In addition, it’s much taller than the HFD-010 (16.7″ vs 28.74″). Be sure to have ample space to accommodate this air cleaner.

If you added this purifier to your interiors today,  you wouldn’t need to change a thing in your home to accommodate it. That’s because it’s black , and black works well with virtually all colors.

The unit looks like a thin, cute tower standing on a circular base. Well, it does seem like it’d be quite easy to topple the thing. For that reason, you’ll want to place it out of the way. But the build seems solid. I doubt it’d break if it got knocked over.

You can count on this filter to remove up to 99% of particles starting from from 2 microns in size. It’s best for relatively large particles such as dust, pet dander, mold, and pollen. It also removes smaller particles, but it’s not excellent for eliminating very small particles, including gases and VOCs.

Also, the machine is AHAM-rated. Its CADR for smoke is 110, for dust it is 100, and for pollen 132. Any purifier with a CADR of above 100 should be a great pick if it ticks all the other boxes.

This air purifier uses two kinds of filters to help you manage indoor allergens. The first filter is a permanent, washable prefilter that captures pet hair, fibers, and other large particles. The second one is an ifD filter, and it handles smaller particles ranging from 2 microns in diameter to much larger particulates.

This air purifier gives the best results if used to clean about 170 square feet. In a room of that size, it delivers 5 air exchanges every hour.

Unlike most Honeywell air purifiers, the HFD-120-Q oscillates. Oscillation is a mightily useful feature in an air cleaning device. It ensures that the unit’s streams of cleaned air reach the farthest places in the room unhindered. The beauty of it all is that you can stop it from oscillating any time you want. But why would you even want to do that? Wouldn’t you want clean air in every crack and crevice?

The manufacturer throws in a bonus: an ionizer. The ionizer shoots out negatively charged ions to freshen your air. These anions also draw positively charged particles like a magnet, forming larger, easy-to-capture particles.

But ozone is dangerous and actually contaminates the air, right? There’s a whole lot of misunderstanding around ozone. While this oxygen-based gas can inflame airways and worsen symptoms in people with respiratory illnesses, it may not harm healthy people if it stays within safe levels.

So, the trick is to buy an air purifier whose ozone concentrations aren’t an iota more than 0.05 ppm. For that reason, ALWAYS pick CARB-certified devices. And the HFD-120-Q is CARB-certified.

Controlling the unit is very easy, too. The control panel features an LED touch button that allows you to effortlessly choose between 3 air cleaning speeds. Compare that with the HFD-010’s 2 cleaning speeds.

Thanks to its ifD filter that has more resistance to air flow, the unit operates quietly on speed 1 and 2. But you’ll encounter louder noise at speed 3. But even on the highest speed, you get no more than tolerable white noise.

And don’t worry about power consumption. The machine is Energy Star rated. Plus, there’s a reminder so you won’t forget to clean the filters. I like that.

Before you whip out that card to place an order, listen to what I don’t like about this machine. The thing isn’t ideal for allergy and asthma sufferers. Why? It’s because it’s not very effective with particles whose diameter is smaller than 2 microns. The smallest particles wreck considerably more havoc than relatively larger ones. So, you’ll likely inhale tons of tiny particles even with this thing running the entire time.

And yes, I’m recommending it. But not for asthmatic folks who also battle different kinds of allergies. Anyone looking for ultra-filtration should buy a device tested to filter the air down to 0.1 microns or even smaller than that.

I also don’t like that at that price you don’t get many smart features. I’ve seen air purifiers in that range that come with features such as Wi-Fi and even Amazon Alexa. It’d be nice if users could remote-control their device or even operate it verbally. But that’s not much of a bummer. I’d not hesitate to buy it based on that shortcoming alone.

Can the ionizer for the HFD-120-Q be turned off? Unfortunately not. The ionizer in this machine is an integral part of its air filtration mechanism, just like it is for the HFD-010. And I’ve heard that breathing ionized air can cause headaches. Well, very few people complained of headaches. But you should know that’s a possibility no matter how remote.

Overall, the HFD-120-Q is a great product, one I recommend with a straight face. It works. I’m not surprised it commands a star rating of 4.3 after nearly 1,500 reviews on Amazon (as of this writing). And did I also  tell you that it comes with a warranty of 5 years? Yes, you heard me right: 5 long years. Doesn’t that show that the manufacturer feels a substantial level of confidence about their product? Honestly, there’s very little not to like about this device.

Best Air Purifier With Washable Filter (Buying Guide)


Buy washable filers save money

An effective air purifier with a washable filter can save you tons of money in the long run.


You want to save money. That’s why you seek a great air purifier that doesn’t have you spending a small fortune over the long term. But you must understand the following fact:


Air purifiers with permanent filters may not perform as well as those with replaceable ones. And the difference can be significant.


Typically, devices with permanent  filters DON’T use True HEPA filters. You’re never going to see 99.97% of 0.3-micron contaminants removed, as is the case with True HEPA purifiers. It’ll always be a lower number, typically 99.00% of 2-micron particulates. They won’t remove bacteria, viruses, and smoke particles very well since these particles are smaller than 2 microns in diameters.

Here’s a couple considerations to keep in mind:


1. Replaceable Filters  vs Permanent Filters vs Washable Filters


Very few air purifiers use permanent filters. In most cases, air purifiers with washable filters also use replaceable filters. Typically, only the prefilter is washable and permanent. Which means you’d have to buy the main filter (s) if you chose such a device. Luckily, some air purifiers use permanent filters. With these, you won’t ever need to buy replacement filters.

Note: ALL permanent filters are cleanable/washable filters. But not all washable filters are permanent filters. Some of the purifiers I’ve described in this post use permanent washable filters while others use both washable replaceable filters + permanent filters. Obviously, you should buy one with a permanent filter if you DON’T want to ever again spend money on filters.


2.Filter Cost


For air purifiers that use both replaceable and permanent filters, know what replacement filter cost looks like. You don’t want to be stuck with enormous filter costs when that’s exactly what you’re running away from. if you’re paying more than $30 for a filter that lasts just 6 months, find better a deal. Since saving money is a critical consideration for you, go for an option with permanent filters. The HFD-010 and HFD-120-Q are great examples of such air purifiers.


3.Your Health Situation


If you battle allergies or have asthma, go for a machine that uses medical grade or True HEPA filters. Please note that washable filters are rarely true HEPA. And HEPA-type filters can’t be expected to remove more than 99% of 2-micron particles.

As an asthma and allergies sufferer, you need a device that’s capable of obliterating even the smallest particles. Medify air purifiers offer down-to-0.1-micron filtration. And they use medical grade H13 filters designed for residential use.


4. Maintenance


Washable prefilters should be washed at least once every month. To clean a prefilter (specifically those types that look like plastic screens), vacuum them first. Then, give them a quick rinse under the faucet. By contrast, HEPA and HEPA-type filters need at least one wash every 3 months. However, you must be ready to wash these filters (prefilters + other filters) more frequently if your area’s air quality is terrible.


5. Filtration Technology


Be sure you understand all filtration technologies a particular option uses. Some air purifiers may use only HEPA filtration + carbon filtration. Others may combine HEPA filtration with carbon filtration +UV filtration and/or ionization.

Generally, the more filtration technologies a device offers, the better. Unless you have asthma and allergies, go for a unit that uses HEPA (washable), carbon, and UV filtration/ionization. Such an air purifier handles odors, particulates, and microbes effectively.


How to Wash a Washable Air Filter


1.Remove the filter from the air purifier. Follow the manufacturer’s instructions to do it properly. It should be pretty easy for everyone.


2. Grab your vacuum cleaner and start suctioning out contaminants.


3. For the prefilter, vacuum it and then give it a quick rinse under your kitchen faucet.


4. Once you rinse the prefilter, dry it in the sun for 24 hours.


5. Also, leave the vacuumed filter (IFD filter) out in the sun to kill germs.


6. Put the two filters into unit and crank it up to continue enjoying clean air.

Pro tip: When it comes to HEPA filters, it’s always best to vacuum them. Washing them isn’t a good idea. And subjecting them to the mighty force of an air compressor isn’t the smartest approach, either.


Vacuum-cleaning filter

Vacuuming vs washing air purifier filters:what’s better? Vacuuming is the best option when it comes to cleaning air filters. Move the end of the vacuum up and down rather than from side to side. 


Even though many people wash filters, it’s just not a good idea. It’s best to just vacuum off the dirt using a powerful HEPA vacuum. I’d also advise you to stay away from air compressors.

Tests have shown that washing is the worst way to clean air filters. Using a compressor is better than washing, but it’s not the best method. Vacuuming is the best thing you can do for your filters. Note: over the long term, vacuuming disturbs the filter’s general fiber structure, making it less effective.

It’s not advisable to wash the filter for the HFD-010. If you don’t have a vacuum cleaner, start saving toward acquiring one soonest possible. Especially if allergen-laden environments tend to be hell on Earth for you.

While washable filters can be washed, washing them reduces their effectiveness appreciably. Vacuum them, instead.

And Now the Winner is…..


The Honeywell HFD-120-Q. I’m convinced that this is the best air purifier with washable filters out there. And why do I think so?

It’s because this air purifier demonstrates impressive performance in terms of sanitizing the air. In addition, its prefilter and HEPAClean filter are permanent and washable. You’ll save a bundle over the long term.

Also, it runs surprisingly quietly even on medium and high. What’s more, setting it up is easy. Finally, the price is reasonable enough. Plus, it offers a 5-year warranty. You also get an ionizer which boosts the machine’s filtration ability while making the air feel cleaner and fresher.
