Abstract
A box-shaped air filter element has a laterally air-tight frame (20) comprising four lateral walls, a corrugated filter means (16) closing the opening formed between the lateral walls of the frame and through which air to be filtered is intended to be led, means (26) arranged at the frame for holding the filter means in place between the lateral walls, and means (14) located at at least a first (13) of the two lateral walls extending substantially perpendicularly to the wave tops of the corrugated filter means and arranged to influence the filter means to maintain the shape by guiding it in a path corresponding to the corrugation. Said first lateral wall (13) and the guiding means (14) are formed from one single continuous sheet element having an outer portion (13) forming a lateral wall and guiding means portions (14) folded inside thereof to bear against the filter means (16).
