Air filter

An air filter for a fresh air system of an internal combustion engine, comprising:

• a filter housing including a housing pot with a pot bottom, a housing lid, a raw air inlet, and a pure air outlet;
• a filter element including an annular filter body composed of a filter material, a first end plate which faces the housing lid disposed on a first axial end side of the filter body, and a second end plate which faces the pot bottom disposed on a second axial end side of the filter body;
• an inner frame including an annular grid body arranged coaxially in the filter body;
• wherein the second end plate includes:
• an annular first seal bearing sealingly against the housing pot;
• an annular second seal bearing sealingly against the inner frame;
• at least one first annular web projecting axially therefrom, a free end side of the at least one first annular web coupled to the first seal via one of welding and plasticizing;
• and
• at least one second annular web projecting axially therefrom, a free end side of the at least one second annular web coupled to the second seal via one of welding and plasticizing.

• wherein the second seal is supported radially on an annular step disposed on an annular collar of the inner frame, the annular collar projecting radially from an axial end of the grid body facing the pot bottom and extending in a circumferential direction;
• wherein the second end plate further includes at least one of:
• at least one first annular web projecting axially therefrom, a free end side of the at least one first annular web coupled to the first seal via one of welding and plasticizing;
