Best Air Purifiers with Permanent/Washable Filters
Air purifiers are some of the most valuable products to keep in the home–but their recurring costs with filters can be a big problem.
Air purifier filters accumulate debris and pollutants and lose their effectiveness over time to the point where they become completely unusable. That means that if you want an air purifier that keeps working indefinitely, you will need to consider replacement filters.
This article explores air purifier options with at least one permanent/washable filter. This means that some of them may come with a reusable filter along with conventional ones that still need to be replaced, but they nevertheless will offer lower costs in the long run by being cheaper to maintain.

According to Winix, the 5500-2 is a formidable weapon against particulates, pet dander, germs, smoke, volatile organic compounds (VOCs), and odors. And we agree: an air purifier that sports the combination of a 99.97% True HEPA filter, a carbon filter, and plasma technology exudes promise and potential. Its room coverage and CADR specs are also great selling points.
The pre-filter is permanent, but it has to be cleaned every 14 days. The carbon filter, on the other hand, is washable and should be cleaned every three months. As such, it’s not exactly the most low-maintenance air purifier on the market. Washing the carbon filter significantly extends its lifespan, yet Winix still recommends to jointly replace the HEPA and carbon filters annually. Luckily, the 5500-2 has a filter replacement indicator to help you out with this.
Aside from its impressive filter lineup, this model makes a mark for having extra bells and whistles that benefit the user experience. Its smart sensors detect VOC, odor, and lighting levels in the room, enabling it to automatically adjust the fan speed and LED brightness to suit its environment.
The 5500-2 also has a sleep mode for silent operation, and at a mere 27.8 dBA, it really is an exceptionally-quiet machine. Aside from a bunch of dedicated indicators and controls, the included remote control brings in added convenience. While it’s true that the short warranty and bulky design can be discouraging for some consumers, this air purifier is so loaded with features that make it impossible to write off.
The Winix 5500-2 boasts a 3-stage purification process that includes a True HEPA filter, a washable carbon filter, and PlasmaWave technology, all on top of a permanent, cleanable pre-filter. Covering areas up to 360 sq. ft. in size, it’s a great all-around option for highly-discriminating consumers considering its robust array of features.
- HEPA filter
- Sleep mode & air quality indicator
- Fights germs
- Automatic fan speed adjustment using Smart Sensors
- Bulky and heavy design
- Filters need to be cleaned regularly
The Envion Therapure TPP240 is chock-full of features and boasts four stages of purification: a permanent HEPA-type filter for particle contaminants, a UV bulb to combat germs, a photocatalyst filter to eliminate smoke and VOCs, and an ionizer to aid the HEPA-type filter. Since it doesn’t use a True HEPA filter, you can’t expect it to be as effective as the Winix model described above. This might explain why Envion decided to add a supplementary ionizer in the mix.
Its CADR ratings are on the modest side of the spectrum, but it’s not the weakest of the bunch. It also technically doesn’t have any filters that need replacing since the HEPA-type filter is permanent and only requires regular vacuum cleaning, but the UV bulb (to which the photocatalyst filter is attached) needs to be replaced every year.
Another selling point that really stood out is its 24-hour timer, seeing that it’s the only model on this list that offers such a convenience. Along with convenient dedicated controls for the ionizer and UV bulb, it’s clear that Envion didn’t leave ease of use out of the equation.
Overall, the TPP240 definitely seems like a steal, as it offers promising features and a great value for the price. If you don’t require outstanding CADR ratings, then you can definitely consider this air purifier a strong contender.
- Has a digital display
- With a timer

The Honeywell QuietClean Tower Air Purifier is the sole model on this list with filters that are all washable and permanent, which makes it a compelling choice for the savvy penny pincher. It captures up to 99% of airborne pollutants like dust, pet dander, tobacco smoke, and pollen using an ionizer and iFD technology—the latter being a relatively-new filter type that’s comparable to HEPA in terms of performance.
The filter requires only rinsing and drying. There’s an electronic filter check indicator that tells you when it’s time to clean the patented filters, but generally, you shouldn’t have to bother washing it more frequently than once a month. Regularly running your vacuum cleaner over the filters should further lengthen the duration between washes.
Note that it has the lowest CADR ratings of the bunch, which makes it ideal for use in smaller spaces up to 170 sq. ft. Its CADR values also suggest that it purifies air at a slower rate compared to the other models listed here. Though it lacks a timer function and a carbon filter for handling odors and VOCs, its lengthy 5-year warranty should tell you that you can depend on it for a long time. In summary, the Honeywell HFD-120-Q is an excellent option if you’re looking for a small-room air purifier that screams dependability and demands minimal maintenance costs.
- iFD filter
- Oscillation controls
- Electronic filter check indicator
- Easy to maintain
- Small room coverage
- Relatively-low CADR ratings
- No timer
- Not as effective against germs and VOCs
Our final air purifier pick utilizes a unique filtration system and offers one of the highest overall ranges–making it a great choice for larger homes and apartments.
The OION Technologies S-3000 air purifier uses what the manufacturer refers to as ultraviolet germicidal irradiation–which can reduce respiratory issues and symptoms. Likewise, the filter works in conjunction with a carbon filter, which gives a considerable edge to purification volume.
However, we weren’t able to find official CADR ratings for any of the filters included in this unit–which means that there’s no clear way to compare the purification levels with the other picks on our list.
Still, the higher volume and larger overall capacity of the OION Technologies S-3000 air purifier, alongside some seriously powerful purification, makes this a great option for getting large rooms purified. Likewise, this is one of the most affordable options on our list by a considerable margin, so if cost is a concern, there are lots to be gained by taking a chance on this tower purifier.
- Quiet fan
- Energy efficient design
- Night light included
