A method adapts a filter medium to predefinable parameters, such as electrostatic charge, flow-rate behavior, dynamic pressure behavior or differential pressure behavior, fraction filtration efficiency and preservation of a constant quantity and quality of fluid additives. At least one of these parameters is adapted by the targeted influencing of the surface energy of the filter medium ().

Method for adapting a filter medium to predefinable parameters and preferably a filter medium produced according to said method

A filter element (), with a preferably multilayer structure of a filter medium (), in pleated form has filter pleats () of different pleat heights (h, h). The filter pleats () with a first pleat height (h) oppose the filter pleats () lower second pleat height (h). The filter element has a throughflow direction for fluid to be cleaned away from a dirty side to a clean side (R). The transitions arranged adjacent to the inner side all conclude along a fictitious circular cylinder (), which penetrates the filter medium () coaxially to its longitudinal axis (LA).
