The sample in question, 3 x 3 x 0.75, took about 5 lbs to compress. I don't know the material but it shouldn't be too hard to figure out.
It's too late for me, having just bought some ceramic filter media, but I can't think of a good reason why it wouldn't be a MUCH cheaper and lighter approach for shower filter media.
And lastly, if the media - ceramic or foam rubber - does clog, only one of them can be "wrung out." So what's wrong with this idea?
