Filter element and air filter

An air filter comprising:

• a filter housing comprising a housing interior, at least one inlet for air to be purified, and at least one outlet for purified air;
• a filter element arranged in the housing interior such that the filter element separates the at least one inlet from the at least one outlet;
• the filter element comprising a filter bellows having
• an inflow face for fluid to be filtered, the inflow face arranged a first axial side of the filter bellows;
• an axially opposing outflow face arranged an at axially opposite side of the filter bellows;
• wherein the inflow face and the outflow face are arranged such that a filter element axis extends through the inflow face and the outflow face on opposing sides of the filter bellows, the filter element axis defining a Z axis of a filter element coordinate system;
• the filter bellows having a front side and a laterally opposing rear side arranged on opposing sides of the filter bellows relative to an Y axis of the filter element coordinate system, the front side and the laterally opposing rear side extending from the inflow face to the outflow face;
• the filter bellows having a first end face side and a laterally opposing second end face side arranged on opposing sides of the filter bellows relative to an X axis of the filter element coordinate system, the first end face side and the laterally opposing second end face side extending from the inflow face to the outflow face and extending from the front side to the laterally opposing rear side;
• wherein a first flow face is either the inflow face or the outflow face relative to flow of fluid to be filtered, the first flow face having
• a first flow face edge defined where the first flow face meets the front side;
• a second flow face edge defined where the first flow face meets the laterally opposing rear side;
• a third flow face edge defined where the first flow face meets the first end face side;
• a fourth flow face edge defined where the first flow face meets the second end face side;
• a plurality of support elements configured as feet arranged on the filter bellows and adapted to support the filter element relative to a filter housing in which the filter element is to be arranged, the plurality of support elements having:
• a first end arranged at the first flow face and on at least one of the flow face edges of the filter bellows;
• an opposing second end, the second end forming a foot, the second end positioned outwardly away from the first end in a direction defined by the Z-axis, the foot configured to contact against the filter housing in which the filter element is to be arranged;
• wherein the plurality of support elements project in the Z axis direction, outwardly away from the first flow face and away from the filter bellows.
