A filter device for filtration of fluid has a filter element of a zigzag-folded filter medium that is flowed through in a radial direction of the filter element. An additive for functional change of fluid properties of the fluid to be filtered in the filter device is provided. The additive is applied circumferentially on the filter element onto outwardly positioned fold tips of the zigzag-folded filter medium of the filter element. |
