I think polyfil batting is so cheap you can just replace it, isn't it?

Does anyone know a type of sponge that can be bought in 12" wide x 16"
deep
x 12" thick pieces. I am looking for the stuff used in aquariums by
companies like Fluval. I am looking for mechanical filtration to put in my
stream. I looked at polyfill batting but I don't think you can clean it.
