I have to tell you something guys, if you need a filter at the gun, your system has some problems. Your air should be free of junk long before it gets to your gun. With a proper free flowing piping designed to cool the air and trap the water, simply by design, along with a filter before the hose leading to your gun, you just don't need anything more. The typical use of these filters are only there to make up for poor plumbing and filtering prior to the gun.
Devilbiss does make a pretty decent in hose filter, but even it is a CFM robber.
I use the following diagram as an example and it has worked wonders. In my garage I used it but went all the way to the end before installing the filter. I only have one hose outlet (in your garage, are you going to be using more than one tool at a time?) It is 35 ft from compressor to that outlet. I have zero water problems.
