An air filter (10) includes an openable filter housing (12) and a filter element (18). The filter housing (12) includes an inlet (26) and an outlet. A filter element (18) with a filter medium (46) is disposed replaceably in the filter housing separating the inlet (26) from the outlet (22). The filter element (18) features on an exterior side facing away from the element interior space (52) on an axial front face relative to the element axis (32) at least one supporting element (58) having at least one supporting lateral surface (60, 61) with at least one cylindrical portion and/or at least one portion with a variable cross-section in the direction of a main axis. The supporting element (58) is supported at least transversely in relation to the element axis (32) with the at least one supporting lateral surface (60, 61) against at least one corresponding support portion (42) on the side of the filter housing (12).

The air filter according to claim 1, wherein the filter element includes a second axial end face;wherein the at least one supporting element (58) is disposed centrally on the element axis (32) on one of the axial end faces of the filter element (18). 3. The air filter according to claim 1, wherein the at least one corresponding support member (42) is disposed centrally on the housing axis, which coincides with the element axis (32) when the filter element (18) is installed in the filter housing. 4. The air filter according to claim 1, wherein a plurality of supporting elements (158; 258) are disposed on one of the axial end faces of the filter element (118; 218). 5. The air filter according to claim 1, wherein a plurality of support members (142; 242) are disposed on the filter housing (112; 212). 6. The air filter according to claim 1, wherein the at least one supporting element (58; 158; 258) and the at least one corresponding support member (42; 142; 242) are arranged at a raw air side of the filter element (18; 118; 218). 7. The air filter according to claim 1, wherein the at least one supporting element (58; 158; 258) is disposed or integrally molded directly on an end disk (54; 154) of the filter element (18; 118; 218). 8. The air filter according to claim 1, further comprising: a sealing member (36; 136; 236) is disposed between, sealably compressed between and contacting the filter element (18; 118; 218) and the filter housing (12; 112; 212). 9. The air filter according to claim 1, wherein an inlet-sided inlet room section (28; 128; 228),an element room section (30; 130; 230) in which the filter element (18; 118; 218) is disposed, andan outlet-sided outlet room section (24; 124; 224) of the filter housing (12; 112; 212) are disposed in sequence and linearly along a flow path of the air through the air filter (10; 110; 210), one after the other. 10.
