Most air purifiers utilize a replaceable filter that helps the device purify the air properly. These filters collect debris and pollutants and are usually quite effective. But, the downside of using these filters is that they need replacing from time to time, which represents a cost.

Some filters can be quite expensive. While the prices of these filters vary, you will have to be prepared to spend hundreds of dollars on these filters every few months or years. Luckily, there is an alternative to that: air purifiers with permanent and washable filters.

These devices have filters that will stay there forever, saving you from the cost of replacing one. But, you will have to be prepared to spend more time on maintenance.

These filters will have to be cleaned regularly, and even more so if the purifier works in a highly-polluted environment. Like regular, replaceable filters, these will get dirty after some time and will start to lose effectiveness. Cleaning them is a must. Perhaps we compromise on the performance a bit, but not by much.

The technology of purifiers with permanent filters has evolved in recent years. They are almost as effective as regular purifiers with replaceable filters and more cost-effective in the long-term.

Though, picking the right one matters a lot, which is where we will help you out. Here are the five best air purifiers with permanent/washable filters.

Best Air Purifiers with Washable Filters

The True HEPA filter is a replaceable filter that will last you 2-5 years, depending on the demands of filtration.

The other two filters (the carbon filter and the PlasmaWave filter) are permanent. It means that they are washable, so proper maintenance is required. It is recommended to clean the weekly or bi-weekly for better results, especially if the purifier is put in a very demanding room to clean.

This purifier features smart sensors that detect and measure the air specifications, so it turns on and off automatically, based on those measurements.

This purifier features a relatively unique technical design. It provides a three-stage filtration: first, it has a washable pre-filter, which is used for capturing larger particles from the air. Then, the air moves through a combination filter – the particle and odor filter combined in one filter. This filter utilizes activated carbon fur better purification, while also saving plenty of space.

Perhaps the best feature of this purifier is its very quiet operation. Even at the highest performance levels, it will still be tranquil compared to other filters (56DB).

  • It will fit anywhere
  • Relatively quiet at slower speeds


  • Not as powerful as True HEPA filters

Are Washable Air Filters Good?

Washable air filters bring a lot of convenience to the table. Those who want to minimize the long-term running costs that True HEPA filters bring will find washable air filters a good option.

One thing that might be leaving behind the washable air filters is the filtering proficiency. But let’s get one thing straight: the difference between True HEPA filters and washable filters is usually not as big as some people try to portray. That is especially the case for the higher-level washable filters; the technology is pretty advanced, so the difference is often minimal.

Some washable air filters have a replaceable True HEPA filter in combination with a washable carbon filter or pre-filter. That is an excellent combination to have: you will get the powerful filtration system from the HEPA filter, and the convenience of having a washable carbon and pre-filter.

Washable filters are only for those people who are willing to put in the time weekly to clean the filters. As the filters work for prolonged periods, they will lose effectiveness due to the accumulation of mold, particles from the air, and other residues, which is to be expected. Especially with higher loads and where the air is worse, these filters will need more regular cleaning.

Replacing filters can be quite expensive, and that is where washable filters have the advantage. Although the initial investment might be higher (sometimes), the long-term costs will be zero or close to zero.

Washable vs Replaceable Filter – Which is Better?

Some owners of purifiers with replaceable filters will argue that it is simply not worth compromising the performance, but is it the case?

Let’s take a closer look at the comparison between washable and replaceable filters.


Yes, the replaceable filters might be more useful for cleaning, especially the smaller air particles. Some True HEPA filters will remove up to 99.7% of all the harmful particles from the air, including bacteria. The truth is that washable filters are not that far behind, though.

Many of these washable filters will get rid of up to 99% of all the particles, although the numbers vary quite significantly here. For a more robust filtration, you might need to spend more. In terms of performance, replaceable filters might have the edge.

Winner: replaceable filters.


Let’s talk about price. In terms of short-term investment, the difference between washable and replaceable filters is not that big. For the higher performance replaceable filters, you will have to spend a lot, just like with washable filters.

It is the long-term costs that set the washable filters apart here. With replaceable filters, you will have to consider spending additional hundreds of dollars on replacement filters. Some will have to be replaced every few months or even years, depending on the quality. With washable filters, you only need to wash them regularly.

Winner: washable filters


When it comes to comfort, it boils down to what you are personally looking for. If you are prepared to spend time cleaning the filter weekly, then washable filters are the way to go. If you don’t have that luxury, then replaceable filters are for you.

The fact is that washable filters require much more time for cleaning them regularly. With replaceable filters, you will only need to replace them every once in a while. So it depends on your preference here.

Winner: tie


At the end of the day, it is really up to personal preference. Some people will love the cost-effective nature of washable filters, while others will look for a higher performance of the replaceable filters. But the difference is minimal, and the long-term costs are higher for replaceable filters.

How to Wash & Disinfect Air Purifier Filters?

Cleaning washable filters is more comfortable than imaginable. Depending on the type of the filter, here are some guidelines as to how to wash and disinfect them.

  • Look out for the indicator to see whether it needs cleaning. If you don’t have one, then wash it every week.
  • Check out the instructions of the provider. If they allow you to clean the filter with water, then do so. You can also use mild soap with it if the filter allows you. Some filters require only regular vacuuming.
  • Make regular checks on your filter and clean it weekly or bi-weekly.

Wrapping Up

Washable filters are certainly a popular option for many people. They represent a more cost-effective option in the long-term, as you won’t need to replace them. In the end, it depends on each person’s preferences.
