Best Air purifier with Washable Filter in 2020

Let’s get real.

While you want the air in your house to be pure; dust, dander, pollen, smoke and odor free, you do not want to buy an air purifier which you will be incurring extra costs every time you want to replace the filter, right?

You want an air purifier which once you buy; you never have to dig into your pocket again to buy anything.

And that is why you are looking for an air purifier with either washable or permanent filters, right?

Come on, the energy costs that you have to meet every month for your air purifier are enough. You do not want yet another cost coming your way.

And that drives us to a very important debate about HEPA filters. Though they are highly effective in cleaning the air in your home to 0.3 microns of cleaning, you will have to replace them every 6 months.

Say for example that you have the Honeywell hpa300. It means that after every six months, you will be replacing three HEPA filters.

And there is still the carbon filters that do away with bad odor that might want to be replaced time and again.

So, do you really want to meet all those costs?

If you are like most people, then the answer is no.

Other than high replacement costs, HEPA filters also bring another challenge. That after every 6 months, you have some old filters that you need to dispose. That in itself is an environmental disaster.

Best Air Purifiers with Washable Filters

So, are there air purifiers with washable or permanent filters that one could buy and forget the replacement headaches?

Well, yes.

In fact, there is a ton of air purifiers with washable or permanent filters out there.

So, let’s dig into them.

But before that, let’s look at the difference between washable and permanent filters.

Washable vs Permanent vs Replaceable filters

As the name sounds, washable filters need nothing but a wash. While they will have indicators that remind you on when you should clean your filter, I would advise that you wash the filters every month.

Washing needs nothing but soap and cold water. So you will be unplugging the air purifier from your power source and remove the filters.

Add soap to your water and dip the filter into the water. Let it sit as the debris, dust and pollen come out of the filter.

You can also shake and agitate the filter a little to remove all the dirt.

Once you are done, rinse it and allow it to dry.

You can use a drier or just leave it in the sun to dry on its own.

Putting a wet filter back into your purifier could lead to mold building up and you do not want this.

For permanent filters, you should not touch them with water. Use a vacuum cleaner to suck out the dirt from them and once you are done, you can put them back.

Replaceable filters (read HEPA filters) should neither be washed nor vacuum cleaned. Anytime you feel that it has done its work and it is full of debris, remove it and dispose.

Get a new one to replace the old one.

Washing or vacuum cleaning would denature the arrangement of the fibers arranged inside the filter.

Top 10 air purifiers with washable/ permanent filters

  1. Honeywell HFD-120 QuietClean

It comes with washable iFD (Intense Field Dielectric) filters that only need a wash after every three months.

Now how an iFD filter works is through electricity. It infuses a charge on the particulate pollutants in the air and then the charged air is passed through the honeycomb of iFD filtering polymers.

Since the particulate pollutants such as dust, pollen and dander are charged, they will get attracted to the filter and stay there. Clean air on the other hand is able to pass through the filter.

Now this working mechanism is nothing but similar to how an air ionizer works.

And we all know that an air ionizer is bound to emit ozone gases since when oxygen molecules are charged, they are bound to combine and form ozone.

So, this should throw you into panic, right?


But the guys at Honeywell have been CARB certified meaning that their filters produce less than 0.05 ozone parts per million and this gives you an assurance that you will not get headache when using the purifier.  I would however not advise anyone suffering from asthma, bronchitis or emphysema to use these iFD filters as the ozone gases could be inhaled and cause lung irritations which could lead to their deterioration of health.

Other than the ionization of air, the electric working of this iFD filters might make you worried about the energy efficiency of the Honeywell HFD-120. But they have an Energy Star Rating showing that they are efficient and will not incur you humongous power bills.

As per the AHAM guidelines, this air purifier has a high CADR of tobacco smoke 110, dust 100 and pollen 132.

What we Loved about the Honeywell HFD-200

  • It oscillates as it works picking dirty air from all corners of your house and then delivering clean air back to all the corner. So every side of your house gets the love.
  • The iFD filters are washable. You need not spend so much money on replacement filters.
  • It is a high tower that picks dirty air over a large surface area.
  • For a 170 square room, you get it purifying the air 5 times in an hour.
  • It is noiseless and will clean air in your house quietly. So you probably have it for your bedroom.

What we did not like about the air purifier

  • It produces ozone and therefore would not be very good for people with asthma, bronchitis or emphysema.
  • The iFD filters are not as effective in removing particulate pollutants from your house as compared to the true HEPA filters.
  • You can only control it manually. No bluetooth or remote control.

2. Envion Therapure with Permanent Filters

With HEPA type filters, the Envion Therapure air purifier is able to clean out dust, pollen and dander from your air. The HEPA type filters are permanent and so you do not need to dig deep into your wallet every six months to replace them.

No, all you need is a vacuum cleaner to suck out all the particulate air pollutants from the filters.

It also features a further UV Germicidal technology filter that will help in cleaning out volatile organic compounds (VOCs) such as paint and carpet fumes.

A third optional filtration feature is the ionizer that will help in removing allergens that were not sieved by the HEPA type filter. This however would pose a danger as it is bound to emit ozone gases into your house.
If you are asthmatic, then do not turn the ionizer on.

It has a high CADR of smoke:137, dust:132 and pollen:155.

What we Loved about the Envion Therapure air purifier

  1. It has permanent filters which do not need any replacement but some simple vacuum cleaning
  2. It is able to clean VOCs from your house.

What I did not like about the air purifier

  1. It produces ozone gases that could be dangerous for people with lung problems.
  2. The HEPA type filters are not as accurate like the true HEPA filters and so they will not clean your air off as many pollutants.
