Abstract

A filter element for filtering a fluid has one or more filter bellows with a specified raw side and a specified clean side oppositely positioned relative to the specified raw side. The filter bellows has a filter medium that is folded along fold edges in a zigzag shape to folds, wherein the folds extend between oppositely positioned end edges of the at least one filter bellows, wherein the filter bellows has parallel extending end edge faces at oppositely positioned end faces. At least one pre-separator embodied as a flat mat is arranged at the raw side of the filter bellows. A frame is injection-molded from plastic material around the filter bellows and seals the end edge faces. The pre-separator is fastened to the raw side with fastening elements arranged at the frame. A filter system with a filter housing is provided with such a filter element.
