A gas filter assembly for removing particulates from the exhaust gas of a diesel engine comprising a housing having an inlet pipe for coupling to the engine and an outlet pipe open to the atmosphere is disclosed. The inlet pipe and the outlet pipe define an exhaust gas flow path. A self-contained filtering means is disposed within the gas flow path. The filtering means includes a plurality of inlet cells, microporous filter elements, filter support elements, and the outlet cells. The components of the filtering means are disposed such that the exhaust gas flows through the inlet cells, then through the microporous filter elements and filter support elements, and finally through the outlet cells. Each of the components of the self-contained filtering means are highly resistant to excessive temperatures, so that the filtering means may be regenerated by heat, which burns off accumulated, typically hydrocarbon, particulates.
