In a hot operation, the particles accumulated is oxidized catalytically due to the catalytically active layer applied to both of the surfaces of the catalytically active layers applied to both of the surfaces of the corrugated inlet and outlet plates. The catalytic treatment of gasified components is carried out on the catalytically active layer applied to the surfaces of the grid unit layers. To heat the catalyzer, the Z-shaped electric heater is interposed between the folds of the grid layers. The heater is connected periodically to the battery or generator in a cold operation. To balance flow rates through the filtering unit and minimize the pressure drop at the filter, the corrugated plates are to be mutually perpendicular, variable in height as well as the distance between the corrugation are to be variable and corrugations are to be made of dense network metallic fiber sintered materials.
