An exhaust gas purification device is described that comprises a housing 10, a chemically active matrix 20 arranged in the housing 10 to define within the housing a supply 14 and a discharge 16 plenum chamber on opposite sides of the flow end faces of the matrix, and supply 11 and discharge 18 pipes connected to the respective plenum chambers. In the invention, the supply pipe 11 is positioned near to the edge at a side wall of the matrix 20 to direct the flow of exhaust gases into the supply plenum chamber 14 generally parallel to the front face of the matrix 20 and the discharge pipe 18 is connected to the discharge plenum chamber 16 near to the opposite edge at the same side wall of the matrix as the supply pipe 11.
