How We Chose These Top Picks

When choosing an air purifier with washable filters, there are certain factors to remember. To ensure that our list of air purifiers featuring washable filters has only the best of the best, we took into consideration the following aspects:


One essential aspect to remember is the size of the room it will be used in. The suction level needed depends on whether the purifier is meant to cater to large rooms or small ones. Using a purifier in a large room that is meant for a small room will only reduce its efficiency. On our list, we’ve included units that work equally well in large rooms as in small rooms.

Mobility Features

Some units can weigh even up to 20 pounds or more.

When looking for a unit, it’s best to look for mobility features such as handles, wheels, and other ways to help you move it from one room to another. Doing so ensures that you can use the same unit in various parts of the house.

The Winix 5500-2 can be truly called a formidable weapon against various particles, such as VOCs, smoke, germs, odor, and pet dander. It comes with a combination of a carbon filter, a 99.97% true HEPA filter, and plasma technology. In other words, it is a unit full of potential and promise, making it our top pick.

While the unit comes with a permanent pre-filter, it must be cleaned every two weeks. Meanwhile, the carbon filter is washable and must be cleaned every three months. Washing this carbon filter significantly expands its lifespan. The company recommends that you replace the filters annually and it has incorporated a filter replacement indicator to assist you with this.

Apart from the impressive lineup of filters, the model also has several extra whistles and bells that are beneficial for the user’s experience. For instance, the smart sensors are highly capable of detecting lighting levels, odor, and VOCs, enabling it to adjust the LED brightness and fan speed automatically to suit the environment.

The unit also comes with a sleep mode, which allows near-silent operation with a noise level of only 27.8 dBA. Aside from a few dedicated controls and indicators, the remote control that comes along with it also adds convenience. Its bulky design can be slightly discouraging for some, but the features this purifier is loaded with make it truly exceptional.

Bottom Line

Pros and Cons of Having an Air Purifier with a Washable Filter

When you see the price of a replaceable filter which you have to replace after every few months, it’s clear why people prefer buying a purifier with washable filters. Of course, not needing to purchase new filters means you get to save money. On the other hand, while washable filters have several advantages, they have some drawbacks too.


  • Reusable filters can catch various airborne particles such as dirt, dander, dust, pollen, and spores.

  • By not purchasing new filters, you save a good amount of money in the long run.

  • The maintenance of the filter is pretty fast and doesn’t demand too much time.

  • You can clean these filters as often as you would like. Frequent cleaning only makes them highly efficient.

  • Some washable filters can’t remove airborne particles larger than 2 microns. So, capturing viruses, allergens, and bacteria with such filters is quite hard.

  • Using washable filters in large rooms means that filters will get dirty faster and will demand regular cleaning.

  • Cleaning the filter often can damage it, rendering the unit not as effective as it was when it was new.

What to Look for When Buying an Air Purifier With Washable Filter

Here are a few things to keep in mind when looking for one of these:


Air purifiers are designed to clean a specific air volume, which limits the maximum square feet they can effectively clear of airborne pollutants and particles. It is important to check the coverage for an air purifier before buying. You will then be able to know which unit is suitable for your space. The coverage will determine the efficiency of the unit. It is pointless to place an air purifier with lower coverage in a large area where it can’t sufficiently improve your indoor air quality.

Cleaning Capacity

An air purifier will be most helpful if it can trap different types of pollutant particles that are in your space. Thus, a good air purifier has to be able to capture all these particles if it is to be useful to you. 

The most effective filter for controlling odor, harmful gases, and air airborne pollutants like VOCs is an activated carbon filter. 

In contrast, a HEPA filter is best for removing airborne particles. A true HEPA removes over 99.97% of particles larger than 0.3 microns, a category that includes common indoor pollution sources like pet dander, dust mite, pollen grains, and mold spores.

Energy Efficiency

It is important to assess the rate of energy consumption of an air purifier before buying. You do not want to have a device that will consume a lot of energy and force you to foot hefty electricity bills. You can check if the purifier has an Energy Certification badge. This will show you whether the product has optimal energy consumption. Even with lower electrical energy usage, you have to ensure the performance is optimal as well.

Air Purifier Filter Comparisons

Here are some filter comparisons to help you decide”

Washable Air Filter vs Disposable


Both filters have a high Minimum Efficiency Reporting Value (MERV) rating. The MERV rate can go up to 16. This means the filters are very effective in capturing minute particles in the air. 


A washable filter can be washed using a vacuum and some water and soap. You will have to clean, rinse, and then dry your washable filter in an open space. 

Disposable filters cannot be washed. You can use the disposable filters for up to one year at most, after which you need to buy a replacement filter.

IFD Filter vs Hepa Filter


Both an IFD and HEPA filter can capture air particles that are at least 0.3 microns or more. This means smaller particles than this size cannot be captured in the filters.


A true HEPA filter captures at least 99.97% of air particles that are 0.3 microns or more.

Filtering happens by physically trapping particles present in the air that passes across them. To remain effective, a HEPA filter has to be replaced after a certain duration.

RabbitAir BioGS 2.0

An IFD filter, short for Intense Field Dielectric, is a type of ionic air purifier that traps 99.9% of particles that are 0.3 microns or more. Trapping occurs through charging them while in the air, which causes them to stick on the filter. 

The filters can be washed to remove the trapped particles. They have a leg up on HEPA filters because they trap particles more effectively without ever requiring a replacement filter.

How Often Should I Wash the Filter on My Air Purifier?

You will need to clean the filters after every thirty or sixty days. Regular cleaning will enable them to work to their greatest capacity. It is important to clean the filter to avoid the build-up of dust and any other air particles that could lead to the formation of mold.

If you do not clean it on time, then you risk spoiling the filter and its efficiency will be reduced. The situation may be worse for users who suffer from asthma and extreme allergies as the accumulation of debris may aggravate these conditions. 

Are Washable and Permanent Filters The Same?

Both permanent and washable filters require low-cost maintenance and help save money. However, there are some prominent differences between the two.


Washable filters can be cleaned with soap and water to remove all the dirt and pollutants stuck to it. After cleaning, the filter must be completely dried for at least an hour before putting it back.


Meanwhile, permanent filters must not come into contact with water at all. However, they can be cleaned with a vacuum. Once you’ve vacuumed it, you can just put it back, and it will be ready to use.
