AirLine Moisture - How to Remove?

I used to have a coil of 3/8 pipe in a five gallon bucket that I would fill with water and ice, kind of on the order of a large "Kool Can", when the humidity got higher when I painted. I would put it at the far end of the shop from the compressor with a water filter immediatly following. It was amazing how much water would be extracted after the air was cooled.
