HEPA Air Purifiers with Washable Filters: Buying Guide

What Does a Washable Filter in the Air Purifier Mean?

As you might have guessed, a washable filter is one that you can wash with water and soap. You simply have to soak, agitate, and rinse the filter, and it is ready to use again!

Washable filters are of two kinds:

Both are almost equally effective at eliminating pollutants from your home. The only difference between them is the design, so you can buy either of the two without worrying about their efficiency. 

Why Buy an Air Purifier with a Washable Filter Over Other Kinds?

When looking for air purifiers, you will also come across models with disposable and permanent filters. So, what makes washable filters the better choice? Let’s have a look:

Washable vs. Disposable Filters

The name of these filters is pretty self-explanatory.

As mentioned above, washable filters are the ones that you take out of your air purifier, wash and rinse with water and soap, and install them back once they dry out.

Disposable filters have a short life – usually 12 months – and once they’re at the end of their life, you will have to remove them.

The problem with disposable filters is that they are very expensive. And since you’ll have to replace them after every few months, the total cost of running air purifiers with disposable filters goes quite high.    

Washable vs. Permanent Filters

Both types require little maintenance and can easily work for up to 15 years without bearing much damage. However, both types require different kinds of maintenance.

You can’t wash permanent filters. In fact, water will completely destroy them and render them useless. So, to clean a permanent filter, you will have to vacuum it to get rid of the accumulated dirt and grime.

Vacuuming a permanent filter is easier and quicker than washing a washable filter. However, vacuuming doesn’t leave the filter as clean, so it will eventually start losing its effectiveness.

What to Look for When Buying an Air Purifier with a Washable Filter

A HEPA air purifier with permanent washable filters is a big investment in your family’s health and well-being. To make sure it’s not a wasted investment, make sure to look out for: 

Coverage Area

The square footage rating of an air purifier is one of the most important things to look out for. The square footage rating is basically the size of the room it can cater to.

You might be tempted to invest in a smaller model for a large room, especially if you’re on a budget. However, it won’t be as effective and your air won’t be as clean. 

Another related factor is the ACH of the unit. ACH refers to the air changes per hour and is the number of times it can completely filter the air of the stated area.

High-powered HEPA filters can change the room’s air multiple times per hour. And while they are expensive, they ensure cleaner air.

Note that the ACH mentioned in the product description is what you will get if you run the unit at the maximum fan speed. 

Filter Life

It’s easy to forget when you last washed your filter. Plus, without opening up the unit and taking out the filter, it can be hard to determine when you need to wash it.

So, if you’re forgetful or busy, look into getting a HEPA air purifier with a filter life indicator. Usually, you will find it in the form of a light and will turn on when you need to wash the filter. 


Since air purifiers with washable filters can’t cater well to large spaces, you will often have to move them around.

Plus, chances are, you will end up getting a fairly large air purifier. So, look for features like caster wheels and handles that will make it easier for you to move it around. 

Build and Durability

Since the air purifier will be cleaning the air for your family, make sure it is made from quality materials. And of course, you wouldn’t want your money to go to waste by investing in a poor-quality unit.

One indicator of good build quality is the warranty. Better warranty coverage usually means higher quality and improved durability.

Apart from the quality, do look for the build. It should be aesthetic and seamlessly fit into different interiors. Of course, this won’t affect the unit’s operation, but it will increase your room’s appeal

Noise Levels

Running a HEPA purifier at full speed can be quite loud, so it’s better if you look for air purifiers with multiple speed options.

Most units have an almost silent operation, so you can place them in your bedroom, too. However, in other cases, air purifiers will make an annoying sound if you run them at high speeds.

But these faster-cycling options are great for purifying your house when you’re out or when you’re doing something where some noise won’t bother you.

Air filters with washable filters can only cater well to rooms up to 250 sq. ft, so they are not suitable for large rooms.

Moreover, you won’t find any innovative features or upgrades on these purifiers. In fact, most of them don’t even have Wi-Fi or remote capabilities.

Lastly, you will only come across limited options. Most manufacturers opt for replaceable permanent filters instead of washable ones. 

Cleaning and Maintenance

Cleaning and maintaining washable filters is very easy. Usually, the unit will inform you when it’s time to wash the filter. Once you get that notification, remove it from the air purifier.

Cleaning the filter is very simple.Just wash it with warm soapy water and then wipe it dry with a cloth. Then let it air-dry completely before inserting it back. Remember, you should never insert a wet filter since it will reduce the unit’s efficiency and may even lead to the growth of mold.

Even if your air purifier doesn’t tell you that it’s time to clean up the filter, it’s necessary that you keep an eye on it. Your filter could be dirty even if the indicator did not light up.

Frequently Asked Questions

Is it recommended to purchase washable air filters?

The initial prices of air purifiers with and without air purifiers are roughly the same. You don’t have to pay anything extra at the time of purchase.

With replaceable filters, you have to pay for the filter replacements every few months. This cost can total up to $200 a year. However, washable air filters help save you from this cost.  

How often should I be cleaning the washable air filter?

It’s best to clean washable filters every month or as soon as the indicator light on your unit lights up.

What’s better? An air purifier with a washable filter or a standard air purifier?

This is more of a personal performance. Most people prefer air purifiers with washable filters because they help save money that you would otherwise have to spend on filter replacements.

Final Verdict: What is the Best HEPA Air Purifier with a Washable Filter?

We found the Hamilton Beach TrueAir air purifier to be the best HEPA air purifier with a washable filter available in the market because of its quiet operation, compact design, and effective True HEPA filter. However, make sure you go through all the models mentioned above and choose the one that stands out to you the most.
