source for foam filter material

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.
