    Abstract: A filter insert has a filter medium body to be flowed through in flow direction from an inflow face to an outflow face. A support element held at the filter medium body has latches to latch the filter insert to a housing cover. A circumferential seal element is held at the support element. The support element has a grid section extending across the outflow face of the filter medium body. The grid section is integrally formed with the latches. A filter device has a filter housing with a housing cover with an inlet and a housing bottom part with an outlet. The housing cover has latches corresponding to the latches of the filter insert. In a mounted state of the filter device, a raw side in the filter housing is sealed relative to a clean side by the circumferential seal element of the filter insert arranged in the filter housing.
