Affordable Compressor Water Filter

90% of it is in the piping. All my piping is 3/4 copper. It runs all the way down the length of the shop and back, then up to the ceiling. Then it gets distributed to each bay. I run a particulate filter near the tanks. I have a dessicant cartridge filter on one drop that is used for plasma, sand, and paint. I only use it for those purposes so it doesn't get beat up too much. For doing small paint stuff it's good enough, but when spraying a car I will buy a disposable, inline, dessicant snake.
