Abstract: A filter element includes: a frame having a peripheral elastomer body in which a reinforcement element is embedded; and a filter pocket. The frame is connected to an opening in the filter pocket with a connection established integrally by the elastomer body. In an embodiment, the elastomer body is molded on the filter pocket.
