Well, if you put two identical filters in the air line, the second will 
also extract water -- perhaps 20 or 30 per cent as much as the first 
one. If you really want dry air, you need a refrigerant drier. Think big 
bucks. Wnat clean air? Get some coalescent filters. More bucks. That's 
how they do it innstrument and medical systems. Don't forget, in the 
typical environment in which most industrial and commercial air 
compressors are used, some moisture and even small bits of solids aren't 
going to cause any problems.
