Abstract: A filter has a filter housing with a filter housing cover coupled to a filter housing part to close a receiving space configured to receive a first filter element and a second filter element each provided with a filter medium body and a frame device around the filter medium body. The filter housing has a radially projecting, circumferential contact shoulder in the receiving space. The filter housing cover, when mounted, exerts an axial clamping force on the frame device of the first filter element. The clamping force is transmitted through the frame device of the first filter element to the frame device of the second filter element. The frame device of the second filter element has a circumferential seal with a hollow chamber profile pressed by the clamping force on the contact shoulder to seal-tightly contact the contact shoulder.

Abstract: A filter has a filter housing with a housing cover coupled to a housing part to close a receiving space receiving filter elements each provided with a filter medium body and a frame device around the filter medium body. The filter housing has a radially inwardly projecting, circumferential contact shoulder in the receiving space. The housing cover, when mounted, exerts an axial clamping force on the frame device of a first filter element. An axial end of the first filter element facing away from the housing cover rests on the frame device of a second filter element. The clamping force is transmitted through frame device of first filter element to frame device of second filter element. The frame device of the second filter element has a circumferential seal with a hollow chamber profile pressed by the clamping force on the contact shoulder to seal-tightly contact the contact shoulder.

Abstract: A cabin air filter system for a vehicle, includes at least one particle filter element and a cyclone separator positioned upstream of the at least one particle filter element. The system includes a particle agglomeration device positioned upstream of the cyclone separator. A method for cleaning air to be supplied to a cabin of a vehicle, with the cabin air filter system.

Abstract: A cabin air filter system for a vehicle includes at least one particle filter element and an adsorption filter element that is spatially separated from the particle filter element and having at least one adsorbent honeycomb. The system further having at least one heating element adapted for heating the adsorption filter element for regeneration and a regeneration flap, wherein the regeneration flap is adapted to switch a regeneration outlet to the environment. The system is operable in a regeneration mode in that the heating element is activated so that the adsorption filter element is heatable to a temperature above a predefined regeneration temperature and the regeneration outlet is opened by the regeneration flap so that a regeneration air flow processed by the adsorption filter element is releasable to the environment. A method for cleaning air to be supplied to a cabin of a vehicle with the cabin air filter system.

Abstract: A filter element has a filter medium body with a raw side and a clean side. A support element is connected to the filter medium body and supports the filter element in a filter housing receiving the filter element. The support element is arranged on the clean side of the filter medium body. The support element is separated from the raw side of the filter medium body by the material of the filter medium body. A filter device with such a filter element and with a corresponding filter housing is provided.
