The invention is directed to a portable and easy to use end-line filter designed to be utilized between a source of compressed air such as a pneumatic hose with an air chuck on its terminal end, and the inlet valve of an inflatable such as a pneumatic tire, to remove moisture from the compressed air before the compressed air enters the inflatable. The invention may also be utilized between the end of a pneumatic hose and a compressed air powered tool. A porous filter media is utilized which has pores that allow the passage of air but do not allow the passage of water or moisture. As the filter becomes saturated, the pores progressively close and eventually block the passage of air. In this manner, the filter automatically indicates the need for a replacement filter element.
