Filter element, housing for a filter system, and filter system comprising a filter element and a housing

A filter element comprising:

• a first end;
• a second end;
• and
• a filter bellows arranged between the first end and the second end comprising a filter media having folds with outer fold edges;
• wherein the folds are oriented such that the folds extend between the first end and the second end with adjacent outer fold edges a distance apart;
• wherein the first end comprises a first notch having a length along the filter bellows from the first end towards the second end;
• wherein the first notch comprises a first outer fold edge and an adjacent second outer fold edge separated a first distance at the first end, the first distance greater than a second distance between the first outer fold edge and the adjacent second outer fold edge at the length of the first notch;
• wherein a distance between the first outer fold edge and the adjacent second outer fold edge tapers down from the first distance at the first end to the second distance at the length of the first notch;
• wherein the length of the first notch extends to a fixation element arranged around the filter bellows;
• wherein a plurality of the outer fold edges are deflected by the first notch;
• and
• wherein the plurality of the outer fold edges cease being deflected at least after interaction with the fixation element arranged around the filter bellows, the fixation element being arranged at least at the length of the first notch along the filter bellows from the first end towards the second end.
