A filter is disclosed for treating a gaseous stream to remove therefrom undesirable components, especially from exhaust gases of engines, and particularly from internal combustion engines, such as, for example, Diesel engines and the like. The filter includes a filter body or element having a plurality of inlet and outlet channels, with the inlet channels being separated from the outlet channels by walls or partitions to provide reaction chambers. The filter body is made a high-temperature-resistant, sintering material, and can be made of metal wire or metal chips which are compacted and subsequently sintered.

A gas filter, suitable for removing soot from a combustion exhaust gas stream, which comprises a plurality of identically sized and shaped gas-permeable formed metal plates, each plate having a front face and a back face, each front face containing a plurality of longitudinal channels positioned between longitudinal channel-separating pieces, each channel having an open end and a closed end provided by a transverse closing cross-piece, with adjacent plates of said plurality of plates being positioned with front faces against back faces and with adjacent plates being rotated 180°with respect to each other to provide a head-to-toe arrangement of adjacent plates for providing rows of inlet channels alternating with rows of outlet channels within said gas filter.
