Posted 2 Years, 10 Months ago WonjTpl Expert Boarder Posts: 124   Does anyone know where I can get some Sponge material to be used as a Filter. All I find in the catalogs are precut to fit certain types of filters. I need to be able to cut it to fit a homemade filter. Any ideas? The administrator has disabled public write access.

I get 1' thick foam and cut-to-fit it to my filters......Frank The administrator has disabled public write access.
