HEPA Filter Replacement

Please see Owner's Manual tab for full instructions on changing the HEPA filter.


  • Replace the HEPA filter every 12 months for optimum performance.
  • Remember that the filter's service life is related to the volume of air that passes through the purifier and the amount of contaminants in the air. If your indoor air has unusually high levels of airborne particulates or contaminants, the filter's service life may be shortened.
  • Regular maintenance helps to prolong the life of the HEPA filter. Keep the area surrounding the air purifier clean, and be sure to change the pre-filter approximately every 3 months.
  • Replace the HEPA filter if you notice a significant drop in air flow or if the filter media is excessively darkened.
  • Do NOT immerse the HEPA filter in water - it is NOT washable.

I have had my air purifier for a few years and, despite having a whole house air cleaner, I find that our second story bedroom benefits from the extra purification.
Does a good job of filtering dust and cat hair (I have two cats). Doesn't last as long as claimed (I have to change the pre-filter every two weeks or so). My Whirlpool air purifier isn't that quiet, but I'm so used to it now that I can't sleep without it. I wish the HEPA filter wasn't so expensive so I could change it more often.
I've used both the Whirlpool brand pre-filters and the no-name ones and although there is a slight difference in the appearance of the products, I'm not sure there's a difference in performance. Both work quite well. I find the pre-filters do not last as long as they are supposed to, but that's because they are doing their job. It's kind of gross how much stuff they pick up and if you have carpet, you will notice a reduction in the amount of dust that comes up when you vacuum. Replacing the pre-filter more frequently if it looks dirty definitely seems to reduce my allergies. The HEPA filter really does last a year, however, which is good, as it's expensive.
The Whirlpool air cleaner is one of the best (have tried others). Very, very quiet operation and easy filter replacement. I love it!
These really collect the dust and other particles you can really see them. These are a good price too.
Price is reasonable and it does a wonderful job of cleaning the air with my air purifier. No problems. Will buy again.
These filters really trap the dust. I have used them throughout my time of owning the Whirlpool Air Cleaner & rely on them to do the job.
Great at trapping dust and pet hair!!
The internal and external replacement filters deliver great performance and are reasonably priced. Also, this Whirlpool unit is amazing.
We have had the Whirlpool room filter unit for two years and these filter are what make it so effective.
