At your local discount store, you should be able to find some fairly large
scouring sponges, I've found that these work adequately as filters,
provided you put a layer of porous cloth over the downstream side to catch
the finest particles. If you're fortunate enough to find the really fine
ones, the cloth isn't needed. These come in 1/4" thick postcard-sized
sheets, which I usually cut up anyway, so give these a try and see if they
meet your needs.

Subject: source for foam filter material
Does anyone know where I might be able to buy some thin
black foam filter
material, to replace the stuiff that was used on my Teral computers?
These systems have a large fan that draws air into the computer, and
the intake air goes through this very thin filter, in order to capture
large particles such as lint.
After 22+ years, that foam is nothing more than dust.
I would need something almost 5 inches wide, that i could then trim to
the proper shape.
