    Abstract: A flat air filter element for an air filter has a filter medium of cellulose material and a sealing element extending circumferentially about the filter medium. Sealing element and filter medium have at least one recess at an outer contour of the flat air filter element. The sealing element has a circumferentially extending holding groove to be engaged by a housing part of a filter housing. The filter housing has a housing pot, a housing cover to cover the housing pot, and a closure element for closing the filter housing. The flat air filter element is secured in the closed state of the filter housing by circumferentially clamping the sealing element between housing pot and housing cover. The circumferentially extending holding groove of the sealing element is engaged by housing pot or housing cover. The closure element of the filter housing is arranged in the region of the recess.

    Abstract: A filter element is provided with a filter bellows that has an inflow side and an outflow side for a fluid to be filtered, wherein the filter bellows is made of a zigzag-folded filter medium with folds with fold edges. The inflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the inflow side and the outflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the outflow side. At least one filter element holding device is provided that holds the filter element in a filter housing. The at least one filter element holding device is connected directly or indirectly with the filter bellows. At least one supporting element supports the filter element in the filter housing; the at least one supporting element is separate from the at least one filter element holding device.

    Abstract: A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.
