ABSTRACT:
A filter element for an air cleaner including a sheet-like filter medium for purifying air when the air is transferred from one side to the other side of the filter medium, a frame member having a flange confining the filter medium and a side wall formed on the flange, and a fibrous mat having cushioning effect. The filter medium is folded in a sawtooth-shaped pattern and extends along a plane. The filter medium has a base contour contained in the plane and has a sawtooth-shaped peripheral edge section extending along a part of the base contour. The flange outwardly projects from the frame. The side wall is airtightly bonded to the sawtooth-shaped peripheral edge section of the filter medium. The mat continuously extends along the base contour and is fixedly bonded to a surface of the flange facing the other side of the filter medium.
