A filter for the separation of impurities from exhaust gases, and in particular, from the exhaust gases of an internal combustion engine, is disclosed. The filter is provided with a filter body comprising a plurality of compression-moulded and sintered filter plates having high temperature stability. The plates are made from powdered metal, metal filings, metal fibers or a mixture thereof, which are disposed over one another or behind one another, and are spaced by spacers to form a plurality of flow ducts between them. The flow ducts are open on one end and closed on the other, with the walls of the filter plates lying between the inlet and outlet ducts representing filter surfaces. One insert or several inserts consisting of catalytic materials or coated with catalytic materials are inserted into the outlet ducts.

A filter, suitable for the separation of impurities from the exhaust gases of an internal combustion engine, including a filter body comprising a plurality of compression-moulded and sintered filter plates made from powdered metal, metal filings, metal fibers or a mixture thereof, which are disposed against one another and separated by spacers to form a plurality of flow ducts therebetween, with the flow ducts being alternately open on one end and closed on the other end so as to form alternating adjacent inlet and outlet ducts with the walls of the filter plates lying between the inlet and outlet ducts providing filter surfaces and the outlet ducts containing catalytic inserts which are made of catalytic materials or which are coated with catalytic materials, said inserts comprising plates extending parallel to said flow ducts and generally extending over the entire length and width of said outlet ducts.
