• a filter body comprising a filter medium folded to a folded bellows comprising folds including two rim folds, wherein the folded bellows is of a one-piece configuration;
• each fold comprising a first fold sheet and a second fold sheet, wherein the first and second fold sheets adjoin each other at a fold edge;
• each fold comprising two oppositely positioned fold end faces;
• wherein the filter body is configured to be installed in an pre-defined installation space vehicle which delimits and defines an installation space volume by a base free-form surface having a shape, a cover free-form surface having a shape, and a side free-form surface having a shape;
• wherein the folds comprises a fold edge height, respectively, and the fold edge heights are adapted to an uneven or slanted course of a contour of the cover free-form surface;
• of the base free-form surface;
• or of the cover free-form surface and of the base free-form surface;
• wherein the folds include one or more first folds with a first fold edge height and one or more second folds with a second fold edge height, wherein the first fold edge height and the second fold edge height differ from each other;
• wherein the folds include third folds whose fold end faces are adapted to a course of a contour of the side free-form surface facing the fold end faces of the third folds;
• wherein a shape of an envelope extending around all of the fold end faces and around the two rim folds deviates from a rectangle.
