Best Air Purifier with Washable Filters

Without further ado, the Pure Enrichment PureZone 3-in-1 is the best air purifier with washable filters. With this unit, pollen, pet dander, dust, odors, and VOCs will stop bothering you. It bundles out fully 99% of allergens and indoor air contaminants. And its UV filtration ability empowers it to remove bacteria and viruses.

What’s more, it’s portable, easy to install, and easy to maintain. In addition, its replacement filter is among the lowest-priced deals I’ve seen. Throw in a 5-year limited warranty, and you have a hard-to-walk away from air purifier with washable filters. All these reasons add up to why many people have given it rave reviews online.


5 Best Air Purifiers with Washable Filters:


  1. Pure Enrichment PureZone 3-in-1

  1. Honeywell 50250-S (390 sq. ft., True HEPA Air Purifier)

  1. Winix 5500-2 (True HEPA+With PlasmaWave + Washable AOC Carbon Filter)

  1. Hathaspace Smart (6-in-1) with True HEPA

  1. Blue Pure 121 with Two Washable Pre-Filters


The Pure Enrichment PureZone 3-in-1 may be the best air purifier with washable filters, but there are others. Hopefully, the information provided here will help you decide whether any of them sounds right for you. Note: These air purifiers aren’t presented in any particular order.

Let’s roll.


  1. Pure Enrichment PureZone 3-in-1


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


Why do I believe the Pure Enrichment PureZone 3-in-1 is the best air purifier that uses 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.


  1. Honeywell 50250-S


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.


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


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


  1. Hathaspace Smart (6-in-1)


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.


  1. Blue Pure 121


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.


The Pure Enrichment PureZone 3-in-1 Won


I’m persuaded that the Pure Enrichment PureZone 3-in-1 is the best air purifier with washable filters out there. Why do I think so? It’s because this air purifier demonstrates impressive performance in terms of sanitizing the air. In addition, the prefilter is washable.

Also, the unit runs surprisingly quietly even on medium and high. It produces a pleasantly consistent white noise. What’s more, setting it up is easy. And filter replacement is almost effortless. Finally, the price is great, and it offers a 5-year warranty.

But I don’t like that you can’t replace the prefilter separately in most cases. Luckily, the replacement filter’s price is reasonably low.

Don’t like the Pure Enrichment PureZone 3-in-1? No problem, visit Amazon. I’m almost certain you’ll bump into an air purifier you’ll love.
