Enviracaire 20500 HEPA Filter Fits 10500, 17000

Time to Change the HEPA Filter on Your Air Cleaner?
Before ordering a replacement HEPA filter for your Honeywell (or other brand) Air Cleaner, be sure to check the model number on the unit. This filter is for the smaller round unit (Model 10500) and for the smaller of the two upright units with handles (Model 17000). I replace my HEPA filter every year because I am very allergic to cigarette smoke, pollens, dust, molds, and other allergens and irritants. Also, this HEPA filter has pre-filters that wrap around it, so you may want to order a box of those, too. The pre-filters should be changed every 3 months, but I check them more often and vacuum off any accumulated pet hair.

NOT a Honeywell product. Doesn't quite fit
It was not clear from this listing that this is NOT a Honeywell product -- though it says it is next to the name at the top of the page. When I opened it, it was immediately evident that it is not the same as the filter that came with my product and is of inferior quality. And worst of all, it does not quite fit correctly. I was able to get the door into place on the unit, but it does not quite close all the way. Very disappointed with the deception and the product.

Note: My item was sold by Alergy Be Gone. Other vendors may offer a different item, but beware.

just as good as any other HEPA filter
HEPA filters were developed by the US Atomic energy commision to remove radio active particles from a contaminated environment. So they are more than sufficient for removing dust, mold spores, cockroach feces and dust mites which have been known to cause respiratory problems such as asthma.

Don't go by the light on the your Honeywell unit to tell when it's time to change the filter because the manufacturer wants you to change it as frequently as possible. When you find that the flow of air has slowed down and dust in the vicinity of the unit tends to collect more, then it's time to change the air filter. Also, vacuuming the outside of the filter may prolong the life. I vacuumed my HEPA and found that there was an increase in air flow afterwards and less dust collecting around the unit.
