and the back-pressure caused by the filter wont burn out the motor?

Polyfill is often used in aquaria (to filter water actually) but doesnt seem to burn out pump engines.

Yeah, as long as you don't pack it ultra tight, it won't unless your pump is ultra-cheap.

LOl my pump IS ultra cheap (6$ and 240 liters an hour max). It was an bargain, normal price wasnt that high either I believe about 20$.
But untill now I wasnt planning on filtering my air. And arent contams more likely to affect incubated jars more then colonized cakes/casings in the pmp/fruiting chamber?

Couldn't you just put the air pump in the middle of a big box of polyfill? (Or is heat a problem?)

I used to have an air pump called a "Silent Giant". It was a heavy monster. When if finally died I did a post mortem. Inside was a tiny little stinker of a pump packed in lots of fine gravel.
