another idea for air compressors, if you have an attic space, is to run the air inlet from the compressor into the attic with large pvc pipe, then use a scavenged automotive air filter housing on the end of that (I used an S10 filter housing) for quick easy and cheap filter changes. firstly, the noise of the compressor inlet is not inside the shop area where you are working, secondly, the compressor is getting cleaner air so less filter changes, thirdly, for my scenario in Canada anyway, it is likely getting cooler air for most of the year so less condensation build up in the system. just having the inlet outside the shop cuts down on a lot of noise-save that hearing.
