Frost King Air Conditioner Filters 15 in x24 in x3 16 in Open Cell Foam

Perfect replacement. Very easy installation. Each envelope contained 1 sheet of thin foam, which was more than enough material to replace filters in 2 of my through-the-wall air conditioners. This foam filter is thin; you can actually see through it. For cutting the correct sizes, I used the original filters as templates. With these new filters in place, my air conditioners are now working fine, blowing and cooling Dust Free. The new filters did not impede air flow. Read more

I bought this to make intake filters for my gaming pc. It worked so well that i also cut one to size and added it to my air purifier for an extra layer and it catches more dust than all of the other 3 filters. Read more

I needed a lightweight and thin filter for my space heater. The original filter was too old and dirty. It was very easy to cut this filter to size to fit it into the back of the space heater to replace the old one. It is thin enough so that airflow doesn't get impeded while still able to trap small debris and dust. Read more

I like these. I know, they’re old school. I use them as a kind of prefilter over the plastic mesh filter in my combo ac/heat unit. They are quite thin, easily installed, no bulk to impact airflow or closing the cover. They cut like a dream for custom fit. As to air quality, well they’re thin and porous so they’re not going to get small dust particles, but getting larger ones, cat hairs, etc., I think they’re worth helping even a little with air quality.

My BedJet II uses a small rectangle shaped foam filter (5" x 10" x 3/16") that catches dust, lint, etc. at the air inlet end of the machine (think inflow on a vacuum). The filter that comes on the BedJet is a simple thin piece of foam that's hand washable or can be gently cleaned with a vacuum. It's a really cheap filter, it's just a piece of foam that doesn't have a frame or anything like that. (Since this functioned as a light duty filter, a foam filter with rigid frame would have been overkill. I first searched the BedJet company website, didn't see anywhere on the site that the Company sold the filters. (Probably no money in selling 10 cent pieces of foam.) So since it was a pathetically simple filter I decided to fabricate my own. Ordered this foam sheet based on it being 3/16" thick; the BedJet one measured about the same thickness. Warning: Compared to the foam filter on the BedJet, this foam is NOT as dense. Will that matter, i.e., is this foam less protective? I dunno. I'm going to keep an eye on how much dirt, lint, or other debris (e.g., the lint from flannel bed sheets) this filter catches compared to the "heartier" BedJet stock filter. If it's not working as well, I will need to search for another foam/filter solution. The foam arrived, I quickly used the existing filter as a template to form the filter. Tools were a pair of full sized scissors for the long cuts, and manicurist scissors for the small cuts. A few snip snip snips, I was all done. At the moment of truth if fit perfect and the machine works great. With one sheet I can make four filters. Can't beat that price point, $1.50 each total cost. (My labor is free.) So subject to the density issue, if you need to make a homemade filter, if this is the thickness and dimensions you need I highly recommend the product. Between me and my family we have four BedJets. So I'll be ordering more sheets so I don't have to think about making filters for a long time. And at this price point I will buy some extra sheets because one can never have enough filter foam for cutting to shape and size and placing it on or in any device that sucks in air. Read more

Great price, arrived on time, works as expected. Read more

Good product, I improvised and adapted it to my Ridgid vacuum because the dust filter was no longer filtrating properly. It was very easy to install and good for this purpose. Thank you! Read more
