Abstract

A filter cartridge for a filter for filtering of fluid is provided with an inflow surface, an outflow surface, and a main flow direction extending from the inflow surface to the outflow surface. A filter body is provided. A filter cartridge frame supports the filter body. A seal is disposed on the filter cartridge frame in the area of the outflow surface and separates a filter interior of a filter into a clean side and a raw side. Another configuration of the filter cartridge is provided that has an edge protection extending externally circumferentially about the filter cartridge frame in the area of the inflow surface. The edge protection connects the filter body and the filter cartridge frame with each other.
