Replaced the old foam filter on my Honda cm250. I just used some zip ties to wrap it around and it's running great.

Large Sheet of Foam Filter Media
I needed to replace the no-longer-available air intake filter on my ancient air compressor. I just cut out a chunk to fit my filter housing. Worked great. I should have enough left over to last for the rest of my life. Note that you should not oil the filter if you are using it on an "oil-less" air compressor. All other uses require that you add some light filter oil to the foam before installing. ... show more

I bought a larger sheet of the foam to use for other air filter projects such as a pair of SU/Stromberg sidedraft carburetors. Regardless, the air induction system on the pressure washer now works properly and the engine has it's necessary clean air supply. ... show more
