Pre-Filter Replacement

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


  • Replace the pre-filter approximately once every 3 months.
  • The pre-filter captures large airborne particles that enter the air purifier:
    • Therefore, it is helpful to keep track of filter replacements for your records, as following this important maintenance schedule will help preserve the life of your air purifier.
    • One way to tell it's time to replace the pre-filter is by its color. Pre-filters are almost black to begin with, and turn a light gray color when they need to be changed.

NOTE:   Do NOT immerse the pre-filter in water - it is NOT washable.

We have used these for many years in our home to clean and filter the air we breathe through our Whirlpool Air Cleaner. The unit we bought from them over a decade ago is still going strong, and we continue to use these pre-filters to this day. We even got a prompt e-mail from Nat'l Allergy when the Whirlpool pre-filter was no longer sold; now we are using this recommended filter which seems to be working perfectly.

Great place to buy allergy items from.

Have been using this product for a long time. Has never failed to perform as expected.

I order these for my old Whispure air filter. They fit perfectly and work perfectly, even though they are made for a more current model.
This pre-filter does not seem to fit well on the air purifier. There is nothing to adhere it to the edges of the HEPA, so I taped it with duct tape on the edges. That said, it is obvious that the pre-filter does collect dust, as it is supposed to, and the entire HEPA-filtered unit does a good job of lowering the dust level in the room.
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.
good product; good price; good value
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.
The pre-filters really trap the dust and are reasonably priced.
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.
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!
