Review: Perfect replacement, Easy installation, Inexpensive! - 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.
Review: Needed To Cut Into Air Filters For My BedJet - PERFECT FOR THE JOB! - 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.
