    摘要： The invention relates to a filter element (10) for filtering a fluid. The filter element (10) comprises at least one filter bellows (12) with a defined raw side (52) and, opposite this, a defined clean side (50), the bellows being made of a filter medium (14) which is folded along fold lines (26) to give zigzag-shaped folds (34) that extend respectively between opposite end edges (22a, 22b) of the filter bellows (12), and which has respectively on opposite end sides (18, 19) mutually parallel end edge faces (20a, 20b), and at least one pre-separator (30) that is in the form of a planar mat and is arranged on the raw side (52) of the filter bellows (12). In that context, plastic is injection-molded around the filter bellows (12) in the form of a frame (28) so as to seal the end edge faces (20a, 20b). Furthermore, the pre-separator (30) is secured by means of securing elements (32) arranged on the frame (28). The invention also relates to a filter system (100) having such an interchangeable filter element (10), and to the use of the filter system (100) for air filtration, in particular for air filtration for an internal combustion engine or as an interior filter of a vehicle.
