ABSTRACT:
An air filter, particularly for the intake air of an internal-combustion engine, including a housing 13, an air filter insert 16 arranged in the housing, and a cover 10 closing off the housing 13. The air filter insert 16 is essentially a rectangular cartridge which has a surrounding seal 18. This seal 18 is clamped in between the housing 13 and the cover 10 in such a manner that it separates the unfiltered-air space from the filtered-air space. In addition, clamps 19 are provided which fasten the cover and the housing to each other and the filter cartridge is simultaneously secured in the housing. Direct supporting contact between the cover 10 and the housing 13 occurs only adjacent the clamps 19, and simultaneously the seal has a very low Shore hardness. As a result, the cover no longer rests as previously on the housing over the whole length of the seal, but only in the area of the clamps.
