A portable filter for a compressed air system is described. The filter is intended to be worn by an operator, and contains a diverter valve whereby air from a remote air compressor enters the filter, and is divided into a flow to a work line, and a regulated flow to a conventional respirator mask to provide breathing air to the operator. The air diverted to the operator passes through a three-stage filter consisting of elements in series which are designed to both remove impurities from the air, and register excessive moisture content therein as a warning to the operator. The flow to the work line is typically a five foot line to an air-driven implement such as a paint sprayer or the like.
