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).

A method of filtering pollutants from exhaust emitted by an internal combustion engine without producing substantial back pressure on the engine comprising the steps of: connecting a filter to an exhaust system of the engine; directing said exhaust through an inlet into a passageway through the filter; deflecting a first portion of the exhaust through a filter media contained within an outer wall of the filter; passing a second portion of the exhaust from the filter through an outlet independently of the filter media; and passing the first portion of the exhaust from the filter through the outer wall independently of the outlet.
