Buyer’s Guide: How to Choose the Best Air Purifier with Permanent/Washable Filter

There are many air purifiers with permanent filters on the market. It is important to know what to consider when selecting the best one.

First of all, understand the difference between permanent and washable filters. While the two terms are often used as synonyms, they’re not the same.

A “washable filter” is one that you can wash with water and soap to remove the accumulated contaminants. The process only takes a few minutes.

They come in two varieties:

  • HEPA filter (kills 99.97% pollutants)
  • iFD filter (kills 99.99% pollutants)

When it comes to performance, the difference of .02% is not much of an issue. They work at the same level, hence you may opt for any of the two.

The second option is a “permanent filter”. These filters require no cleaning. In fact, exposure to water may ruin the filter. They are cleaned with a vacuum cleaner.

Other than this, some units let you add additional filters as well. This factor can be important when selecting an air purifier.

Some other things to remember:

  • Area: The choice of a purifier depends largely on the size of the room you need to clean. Calculate the size of the room and pick a purifier that can circulate and filter air about 5x per hour. A weak purifier will not be able to clean a big room. Our personal favorite is Envion Therapure TPP240 Permanent HEPA Type Air Purifier as it’s suitable for 500 sq. ft. rooms. You may also opt to use two purifiers in a single room but this will cost you more.
  • CADR Rating: Shortened for Clean Air Delivery Rate, the ratings indicate how reliable a purifier is. The higher the rating, the better it is at cleaning specific contaminants. For example, look at “smoke” CADR rating to know how well a purifier can remove tobacco smoke. You may use this rating to compare different options. Our personal favorite is Winix 5500-2 Air Purifier with True HEPA, PlasmaWave and Odor Reducing Washable AOC Carbon Filter as it’s rated quite high.
  • Size and Weight: This is of huge importance if you want a mobile purifier. While most units weigh about 15 pounds, you may even be able to find purifiers under 5 pounds. Our go-to option would be Honeywell HFD-120-Q QuietClean Tower Air Purifier with Permanent Washable Filters as it’s quite easy to move around.
  • Environment: Consider the kind of pollutants and contaminants found in your surroundings when selecting a purifier. One purifier may not be able to fully eradicate all kinds of contaminants. For example, Honeywell AirGenius 5 Air Cleaner/Odor Reducer 250 sq. ft can be a good choice if you have pets as this purifier can reduce the risk of allergens and also make the room smell fresh.
  • Looks: While not the most important factor, looks can make a difference since you’d be keeping the filter out in the open for one to see. Choose a machine that looks good and goes well with the overall theme of your house. Blue Pure 211+ is a good pick as it offers color customization.

Other than this, make sure to pick a unit that matches your budget, comes with a decent warranty, offers good customer service, and is easy to use.
