 Pre-Filter Fits All Honeywell HEPA Air Cleaners March 17, 2001
94 out of 98 found this review helpful
I follow the manufacturer's recommendation to change the pre-filter every 3 months on all my Honeywell Air Cleaners with HEPA filters. These replacement filters come boxed in a set of two. The pre-filter simply wraps around the round HEPA filter, which is inside the unit, and attaches to itself by means of two velcro fasteners. It takes less than five minutes to change the pre-filter. In between changes, I vacuum my pre-filters to remove accumulated dust and pet hair from them. These pre-filters do help to remove some odors from rooms, especially if you are able to keep the space enclosed where you have the air cleaner running.Be sure to keep a box or two of these pre-filters on hand in case they become back ordered. The HEPA filter needs to be changed in 1-3 years, depending on conditions where it is located.

This filter is larger (taller) than it needs to be for most machines. You simply trim the filter (and it's got pre-made perforations) to the height of your machine. And yes, this means that if you have one of the smaller machines, one which is less than half the height of the pre-filter, you might get two pre-filters for the price of one. Bonus.

I'd recommend getting the Honeywell version over the cheaper imitations, so as such, this receives my highest rating. It comes with good installation instructions, and getting it out of the box and onto your Hepa filter is a breeze, so if you're in the market for one of these suckers (which if you're like me, means you're in the market every 3 months), then grab it, it's cheap and you can count on the quality since it's made by Honeywell.
It's my choice in universal replacement pre-filters! June 13, 2007

Changing my Enviracare pre-filter is one of the great pleasures of my life. Just knowing that we're not breathing in all that gunk makes it all worthwhile. Honeywell has a very low-tech solution to fitting this oversized filter: cutting it with a scissor. I would recommend trimming the filter material over a newspaper, as it can leave carbonaceous residue. Also, remove the old dirty filter inside a large garbage bag, as it's very easy to shake loose and spread around the dust and particulate crud you're trying to contain.
Good filter, I've used it for years December 14, 2007

This is a good prefilter for my Hepa machines. I live in a congested part of NYC with lots of traffic and have two filters running at all times to keep the apartment's air clean. These prefilters last between 2 and 3 months, depending on local air quality. When I change them I can really appreciate them - all that disgusting gunk on the filters instead of in my lungs. As others have said, the filters come two in a package. Cut them in half widthwise (do it over a counter because the charcoal gets all over), then wrap the prefilter around the Hepa filter and secure with the supplied velcro strips. That's it, quick and easy.
