摘要： A filter bag for a pocket air filter includes two side walls. Both lateral edges of the side walls, and the edge of the base are welded to each other. The side walls are made of an air-permeable filter material which can be ultrasonically welded, and at least part of the surface of said side walls is joined by means of interconnected welded spacer elements running substantially parallel to said side walls. The spacer elements are formed by an intermediate layer made from a strip of flexible material, which is alternately welded to the side walls in zig-zag fashion.
