Abstract
A cartridge filter including a plurality of filter media sets, wherein two of the plurality of filter media sets are arranged in a V-shaped manner, and a frame for receiving the filter media sets. The frame is formed by four elements which are each configured in one piece: an inflow-side upper plate, an outflow-side base plate and two side plates.
