Abstract

The invention relates to a filter element and filter system for filtering a fluid. The filter element (10) includes at least one, in particular flat filter bellows (12) made of a filter medium (14) having an intended raw side (52) and an intended clean side (50) situated opposite thereof. A flatly affixed sideband (28) is disposed at the front faces (16, 17, 18, 19) surrounding the filter bellows (12). A circumferential seal (32) is disposed at an outside of the sideband (28). The sideband (28) has a flap (36) projecting over the clean side (50) of the filter bellows (12), the flap (36) being arrangeable at the front faces (16, 17, 18, 19) in a V-shaped back-folded manner over the seal (32).
