How Do We Measure?

The Washable/ Permanent Filter The most important criteria for this list. All the air purifiers listed here must have at least one washable and reusable filter. Whether if is a HEPA or pre-filter, we will compile, compare, and test the quality of the permanent filter. Priority will be given to filters that can withstand long-hour usage while retaining efficiency. Extra bonus point if there is more than 1 permanent filter in the air cleaning machine.
Room size/ Coverage The bigger room size a washable filter air purifier can cover, the better chance of it holding its place. We will also measure the airflow delivery rate or CADR to determine how effective is the air cleaner. The higher the numbers, the faster the air purifier can remove airborne contaminants.
Cost of ownership Pricing is an important factor when determining the best air purifier with a washable filter. We will look into every aspect including the HEPA filter quality, airflow performance, dimension, ease of use, and features. As most air purifier comes with multiple filters, we will take the cost of replacing the non-washable filter into consideration as well. After all, what is the point of buying a washable air purifier that is going to cost as much as a conventional HEPA air cleaner?

How to Choose the Best Air Purifier with Permanent/ Washable Filter

There are many features to consider when picking the best washable air purifier with a permanent filter. To assist you in your buying journey, here are the things to look out for when purchasing an air purifier with a washable filter.

  • Types of washable filters - Every filter has different functionality and capabilities. A multiple filtration setup is great at removing different types of pollutants in the air.
  • Permanent pre-filter - Designed to capture large particles and withstand constant cleaning without disintegrating. The extra layer of filtration can also help extend the life of other filters.
  • Reusable HEPA-type filter - A popular washable filter that can remove 99% of airborne particles as small as 2 microns.
  • Activated carbon filter - Remove smoke and odors from cigarettes, pets, fireplace, VOCs, and cooking. Because of the absorption chemical, carbon filters are non-washable and require replacing when it is due.
  • Coverage area - Very important as it determines if the air purifier can cover the room size you need it to purify. Measure your room size and pick a model that can support at least the minimum requirement. Most air purifiers with a permanent filter can cover small to medium room sizes.
  • Dimension - The good thing about an air purifier with a washable/ reusable filter is the overall size. Most models are in slim tower form thus will fit well in tight spaces. If you plan to place the air purifier on a desk or somewhere with limited space, choose the most portable model.
  • Warranty - The longer the warranty period, the better peace of mind you will have with the air purifier. Keep in mind that the manufacturers' limited warranty may not cover the same thing. Also, take into account the customer service and service center location. When there is a defect, you might need to ship back the air cleaner with self-incurred cost.
  • CADR - Acronym for Clean Air Delivery Rate. A numerical rating set by AHAM to determine how many particles have been removed in a fixed area. Since this is not a compulsory measurement, not all air purifiers will participate in the test. If you are very specific on a type of filtration like dust, go with the model that has the best dust CADR output.
  • Noise level - Look for a model that has the option of low noise output. Having multiple fan speeds allows the air purifier to run silently without any distraction. Auto mode will autonomously control the fan speed based on surrounding air quality. Activate sleep mode will dim the indicator light and set the fan speed to low.
  • Cost of ownership - The biggest advantage of owning an air purifier with washable filter is the running cost. Rather than having to replace the filter at a cost, you can clean and reuse the permanent filter for an extended period of time.
  • Energy efficiency - An air purifier does not consume a lot of electricity like most are led to believe. However, some models are Energy Star Rated therefore more energy-efficient than the others. Compare the power watts output and buy a model you are comfortable with.
  • Other features - While an air purifier's sole purpose is to clean the air, there is no harm in having more supporting features to help you achieve that. For start, a timer would be very helpful to manage the runtime while you're away. Air quality indicator will let you know how dirty the surrounding air is. The filter change indicator will alert you to wash or replace the filter when the time is up. The remote control allows you to control the air purifier remotely without having to get up.

A washable filtered air purifier that many will be familiar with. Honeywell AirGenius 5 is the top-of-the-line model that goes beyond what most reusable air purifiers would offer. House in a modern black exterior with bottom blue accent light, the 11.5 x 29 x 11.5 in dimension and 14 lb weight is not overly bulky for small home use. Being a Honeywell, build quality is great where you can move it from room to room every day without ever feeling the whole thing would fall apart. There are nice touches added to the design such as the premium touch screen control, rear hidden air inlet, and a 7 preset timer that can be set when to turn it off. Complimenting all that is the 5 years warranty that would give the owner worry-free ownership.

The best air purifiers with permanent filter for large room. The only thing you need to add or replace is the optional odor pre-filter.

Here is Honeywell AirGenius 5 specification:

  • Room Coverage - 250 sq. ft.
  • Fan Speed - 5
  • Air Filtration - ifD Micro-Filter, Washable pre-filter, Ionizer
  • Maintenance Cost - 0
  • Washable Filter - Yes

Honeywell AirGenius 5 patented QuietClean ifD technology is one of the most effective reusable filters of all time. It can remove up to 99.9% of airborne particles including dust, mold, pollen, pet dander, bacteria, and viruses. There is also an optional ionizer that emits millions of negative ions into the air. The released ions cause other particulates to merge and eventually fall for the ifD to capture due to the increased weight. Finally, there is a washable foam pre-filter that is reusable yet great at trapping large particles. We highly recommend you opt for the odor & gas reducing pre-filter upgrade that does the same thing plus removes toxic fumes like VOCs.

With a highly adjustable 5 cleaning mode (Sleep, Germs, General cleaning, Allergen, Max cleaning power) plus oscillation, there is a use for every scenario. Ideal for bedroom and living room with the option to crank it up the performance during allergy season. At full speed, AirGenius 5 can cover up to 250 square feet of room space. CADR mirrored the coverage at 160 cfm for dust, 170 cfm for pollen, and 161 cfm for smoke.

Let's address the elephant in the room. The drawback of a permanent filter over a conventional HEPA filter is the efficiency. Adding to that, you will have to deal with the hassle of filter cleaning compared with a conventional HEPA filter that only has to be replaced annually. Lastly, all carbon filter is non-washable as it uses chemical adsorption materials. You will still need to replace it in due time. Then again, if you prioritize convenience over absolute performance, Honeywell AirGenius 5 will serve you well.

In short: The best air purifiers with permanent filter for large room. The only thing you need to add or replace is the optional odor pre-filter.

Winix 5500-2 is not a washable air purifier by any stretch of the imagination. We decided to include it on our list is because the overall package is too good for you to skip it.

A hybrid washable and HEPA air purifier that exceeds in every aspect. This would be the perfect model if you don't mind the high annual recurring cost.

Housing the multiple filtrations is a 15 x 23.6 x 8.2 inches body with 15.4 lb in weight. Not the smallest and lightest in its class but still portable enough for room to room purifying. The front panel can easily be detached to remove the permanent pre-filter for cleaning without the need to flip around the air purifier. As with all Winix models, fitting is tight with no leakage and harmful gas released during operation.

Winix 5500-2 does not hold out on features either. You'll get dual sensors, a front air quality indicator, remote control, filter change indicator, and a timer. There is also the auto mode that automatically sets the fan speed to high when the air quality drops. Sleep mode activates once the light is off and locks the fan speed to the lowest with dimmed down indicator light.

Here is Winix 5500-2 specification:

  • Room Coverage - 360 sq. ft.

  • Washable Filter - Yes

As for odor and smoke particles, the activated carbon filter will have no trouble removing the harmful particles from cigarettes, cooking, VOCs, pet, radon, and asbestos. Lastly, PlasmaWave will produce Hydroxyls to break down stubborn allergens for the filter to capture.

That said, Winix 5500-2 is more of a hybrid washable air purifier with a permanent filter. Bar the permanent pre-filter and PlasmaWave, every filter is non-washable with a limited lifespan. You are expected to replace the true HEPA filter and activated carbon filter annually in order for it to work. Noise level is also on the louder side when compared with other washable air purifiers.

A triple-action purification with a huge running cost. Envion Therapure TPP230H is not your typical washable HEPA filter air purifier. It is a mix between a conventional and a permanent air purifier. For example, you can clean the HEPA-filter to boost performance by removing trapped dust, mold, pollen, and dander. At the end of 6 months, you will still need to replace the HEPA filter. The UV-C Germicidal lamp is excellent at killing bacteria and viruses but again, there are limited usage hours. Finally, there is the non-washable photocatalyst filter that can remove chemical odors like asbestos, VOCs, tobacco smoke. Very useful but can be a hassle to change.

A wonderful UV air purifier with a washable HEPA filter that can be reused for years to come. You do have to replace the UV light to enjoy light sanitization.

Here is Envion Therapure TPP230H specification:

  • Room Coverage - 350 sq. ft.
  • Fan Speed - 3
  • Air Filtration - HEPA-Type filter, Ionizer, UV-C light + Photo catalyst filter
  • Maintenance Cost - +- 83 dollars
  • Washable Filter - Yes

Envion Therapure TPP230H is centered around a HEPA-Type filter that captures microscopic particles. While it is not the same filtration level as a True HEPA filter, you do gain the advantage of being able to clean and reuse it many times. Another filterless technology is the ionizer that releases millions of negative ions into the air. The charged ions will merge with other positive ions pollutants so it will fall for the HEPA filter to capture. Lastly, there is a UV lamp + photocatalyst filter that kills and halts pathogens like mold, mildew, germs from spreading. Very effective even though the light intensity will drop as time goes by before it is needed to be replaced.

Ideal for medium to large room purifying. At full speed, Envion Therapure TPP230H washable HEPA air purifier can cover up to 350 square feet of room space. With its low noise output, you can place it in a bedroom, living hall, office, basement, or anywhere you spend the most time in. Official CADR is at 132 cfm for dust, 155 cfm for pollen, and 152 for smoke. Not the finest but certainly far from weak as well.

An inexpensive air purifier with a washable HEPA filter and a few flaws of its own. The main one is the filter replacement can cost higher than a brand new unit in just 2 years' time despite being washable. CADR is slightly on the lower side compared with its purifying coverage. Controls and features are a little bland as well with zero autonomous support. If you want an air purifier with a permanent HEPA filter and zero recurring cost, look elsewhere.

In short: A wonderful UV air purifier with a washable HEPA filter that can be reused for years to come. You do have to replace the UV light to enjoy light sanitization.

Let's get this out of my chest. Hamilton Beach TrueAir Compact Pet is not the best air purifier with a permanent HEPA filter. However, it still offers good filtration and more importantly, it is dirt cheap with almost zero maintenance cost. The small 8.1 x 16.4 x 10.8 inches framework size fits perfectly for most homes even if you don't have any room space. Thanks to the unique design, you can place it standing up or lying flat without affecting its airflow distribution. Fitting is solid with a removing panel that snaps in and out with ease even after multiple rounds of cleaning. A standard 1-year warranty is inclusive that is expected even at this price point.

An affordable, compact air purifier with a washable HEPA filter. Adding the cheap carbon zeolite filters helps remove nearby smoke and odors that most filtration can't.

Here is Hamilton Beach TrueAir Compact Pet specification:

  • Room Coverage - 140 sq. ft.
  • Fan Speed - 3
  • Air Filtration - Pre-filter, HEPA-grade filter, Carbon zeolite filters
  • Maintenance Cost - +- 10 dollars
  • Washable Filter - Yes

With proper cleaning, no dust, hair, or pet dander will be too difficult for this pet machine. Inside the 3-stage filtration, there is a permanent pre-filter that can be wash and reuse indefinitely. It is there to trap large particles like dust, hair while protecting the washable HEPA filter. The permanent HEPA filter also does not require replacing where it can be clean with a vacuum cleaner. At full capacity, the HEPA-grade filter can trap 99% of airborne pollutants like mold, pollen, mildew, and germs that are too tiny for our naked eyes. For smoke and odors coming from cigarettes, pets, or food, you have carbon zeolite filters that can deal with it. Unfortunately, it is the only filter that is non-washable and has to replace on time to maintain its efficiency.

Hamilton Beach TrueAir Compact Pet can reach up to 140 square feet of room size. Not the widest in air purification but will serve its purpose well. You can set it to WhisperClean for a completely silent operation or QuickClean for maximum performance. This compact air cleaner is best used on top of a cabinet, work desk, or tabletop lying either vertically or horizontally. Do not expect anything more than that and you'll be fine.

Hamilton Beach is a washable HEPA filter air purifier that everyone could afford. There are some downsides to it though. First, it has a rather weak airflow output that is only meant for close-range purifying. Features wise it is as simple as it gets with only 3 fan speeds to tinker around with. The non-washable carbon filter also requires replacing in order for it to function properly. All in all, this is specifically for people that need clean air yet do not need all the fancy stuff.

In short: An affordable, compact air purifier with a washable HEPA filter. Adding the cheap carbon zeolite filters helps remove nearby smoke and odors that most filtration can't.

The third ifD ready model we have in our best air purifier with a washable filter list. Honeywell HFD-120-Q QuietClean Tower is one of the more dated models here. You can tell from the exterior design and clunky controls that may not be appealing for some. However, the 9.6 x 26.1 x 7.9 inches dimension is highly usability that isn't too tall or big to fit in most homes. You can easily move it around by grabbing on the handle or bring it out for cleaning. Build quality is great and you do get the Honeywell comprehensive 5 years warranty as standard.

An older, dated washable air purifier that still works like a charm in removing airborne pollutants. Go with this if you want the cheapest ifD powered model currently available.

Here is Honeywell HFD-120-Q specification:

  • Room Coverage - 170 sq. ft.
  • Fan Speed - 3
  • Air Filtration - Washable pre-filter, ifD filter
  • Maintainence Cost - 0
  • Washable Filter - Yes

Honeywell HFD-120-Q QuietClean uses the familiar ifD filter that requires no replacement. Same case with the permanent pre-filter that can be reused after cleaning. The washable air purifier can remove airborne mold, spores, pollen, dust mites, pet dander, and even germs. At the end of the month, simply vacuum out all the pollutants and the filter will be good as new. Like every other Honeywell series, smoke and odor filtration can be done with the HRF-K2 Filter K Pre-filter upgrade.

Take nothing away from its air cleaning capacity as it is still a 3-stage filtration air purifier classic setup. Honeywell HFD-120-Q can cover a good 170 square feet of space silently thus perfect for offices, bedrooms, or a laundry room. CADR is acceptable too at dust-free 100 cfm, pollen-free 132 cfm, and smoke-free 110 cfm range.

So what's the con with this washable air cleaner? It is not effective against smoke particles unless you opt for the carbon pre-filter upgrade. Features are rather plain compared with the AirGenius series. Interval cleaning is unavoidable and can be a hassle depending on how dirty is the indoor air. Lastly, it is not a direct replacement for a True HEPA filter. Go with HFD-120-Q QuietClean if you want to save up some cash and don't mind the slightly weaker performance.

In short: An older, dated washable air purifier that still works like a charm in removing airborne pollutants. Go with this if you want the cheapest ifD powered model currently available.

How Long Do Air Purifier Permanent Filters Last?

Generally, a permanent pre-filter and permanent HEPA filter will last 2 to 5 years before requiring replacing. A non-washable carbon filter sheet will have to be replaced every 3 months. The types of filters and how well it is made play a role in the longevity of the filters. If the permanent filter is made of mesh metal steel or other durable materials, the filter can last longer with proper care and maintenance. Read the manufacturer's instructional manual for more details on the filter usage life.

What Are The Differences Between Washable And Permanent Filters?

For performance, permanent filters are better at trapping finer particles like pet dander, mold, bacteria than washable filters. Maintenance wise, a permanent filter is much quicker to clean with a vacuum cleaner and you can reinsert it back into the air purifier straight away. A washable filter can be clean thoroughly with mild soap and water. It is more time-consuming though as you will have to wait for the filter to dry before inserting it back to the machine. These are the subtle differences between them. Since both filters are reusable, you will save a lot of money in the long run.

What Is A Permanent HEPA Filter?

Permanent HEPA filter is a washable and reusable version of a normal HEPA filter that can trap 99.97% of particles in the air as small as 0.3 microns. By cleaning the permanent HEPA filter when it is dirty, you do not have to bear the extortionate filter replacement cost. However, its efficiency is typically one notch below a certified True HEPA filter.

How To Clean A Reusable Filter and Permanent Filter?

First, check the manual if the reusable filter can be wash with water or vacuum. Turn off and unplug the air purifier from the power source. Remove the front cover and carefully take out the permanent filter. Use a vacuum cleaner and gently vacuum on a vertical stroke without applying too much pressure. For a washable filter, rinse it with water for a couple of minutes, shake out the excess water, and most dust should fall off. For stubborn dust that is still stuck in the filter, use a brush and gently scrub away the trapped dust. Leave the filtered air dry to prevent mold and germ growth. Once dried, reinsert the filter accordingly, and close the front panel. Repeat the steps every 2 to 3 weeks or when the air purifier filter check indicator light is up. The washable filter needs to be clean regularly to maintain the filtration performance and lifespan. You can learn more about how to clean an air purifier with a permanent filter here.

How Much Money Would You Save With Permanent/ Washable Filter?

On average, you will save 80 to 100 dollars annually on filter replacement. The total cost of 2-3 years filter replacement can be equivalent to a brand new model. The longer you own the air purifier with a permanent filter, the more money you will save on filter cost. Since most washable air purifiers are priced affordably, it is perfect for a person that doesn't want to spend too much money on one.

Are Washable HEPA Filters As Effective?

Permanent and washable HEPA filters are effective in removing particles in the air similar to a HEPA filter. For example, iFD filter from Honeywell is washable, reusable, and has a 99.99% air cleaning efficiency. A washable HEPA filter is also eco-friendly and cost-saving with no expensive filter replacement to incur.

Air Purifier Permanent Filter VS Replaceable Filter

A permanent filter can capture airborne particles as small as 2 microns with an efficiency of 99%. A replaceable filter can capture finer particles as small as 0.3 microns with an efficiency of 99.97%. A permanent filter is reusable but requires cleaning every 2-3 weeks to maintain its efficiency. A replaceable filter cannot be clean and needs to be replaced once it is worn out. There is no maintenance cost for an air purifier with a permanent filter. A replaceable filter will cost you between $50-200 annually depending on the model.

To recap, here are the pros and cons of a washable permanent filter.

Pros

  • Can capture most household contaminants in the air.
  • Reusable thus saves money on filter replacement.
  • No dip in filtration performance with proper cleaning.

Cons

  • Less effective than a True HEPA filter.
  • Requires constant cleaning especially in a poor air quality environment.
  • Improper cleaning and maintenance may damage the filter.

Opt for a filterless air purifier instead if you need a completely 100% filter-free model without the hassle maitainence.
