Abstract (en)
[origin: US6312489B1] A filter element for an air filter, including a filter insert (2; 8; 10) and a seal (6) extending around the outer edges of the filter insert on the flat side thereof; the filter insert being folded in a zig-zag or pleated form and being composed of filter paper or filter fabric. The filter element (1; 7; 9; 10) rests against parts of a filter housing through the seal (6). The folded filter insert has a contour on one side which deviates extensively from a plane, at least in certain predetermined areas, thus creating a continuous zig-zag fold.
