Abstract

A flat filter element to be mounted in a filter housing has an inflow surface and an outflow surface downstream of the inflow surface in a flow-through direction. A filter medium extend between the inflow surface and the outflow surface. A sealing section extends circumferentially relative to the flow-through direction. A seal fastened to or interacting with the sealing section is provided, wherein the seal, when the flat filter element is mounted in a filter housing, separates an inlet of the filter housing for air to be purified from an outlet of the filter housing for purified air. A first functional element section is arranged on at least one circumferential side of the filter medium so as to be spaced apart from the circumferentially extending sealing section. The first functional element section is attached to a lateral strip and the lateral strip is attached to the filter medium.
