Abstract

An exhaust filter (10) removes pollutants from exhaust emitted by an internal combustion engine without producing substantial back pressure on the engine. The exhaust filter (10) is assembled from a frame (16), a mounting sleeve (14), and a replaceable filter cartridge (12). A series of baffles (40, 42, 44, 46, 48, and 50) are located along an exhaust passageway (84) within the cartridge (12) for diverting a first portion (88) of a flow of exhaust (80) through a filter media (78). An outlet (86) passes a second portion (90) of the flow of exhaust (80) from the exhaust filter (10) independently of the filter media (78).
