A filter element may include a filter medium extending in an extension direction and including a filter material separating clean and raw sides of the filter element, and two seals arranged at two end faces of the filter medium located opposite one another in the extension direction, so that an inner side of each seal may be arranged lying against the associated end face in a fluid-tight manner. The two inner sides, jointly with an inner circumferential side of the filter medium, may partly limit a filter element interior space. The filter medium, in a section running perpendicularly to the extension direction, has an open U-geometry or V-geometry with two legs.

A brake dust particle filter for a disc brake assembly has a ring segment-shaped housing configured to at least partially accommodate a brake disc. The housing has first and second housing side walls which are axially spaced apart from each other. The housing has a housing circumferential wall section extending radially outwardly in a circumferential direction and arranged between the first and second housing side walls. One or more guide ribs project inwardly with an axial component into the housing interior away from the first housing side wall. The guide ribs are arranged adjacent to a respective opening in the housing side wall. The guide ribs are covered at least partially by a filter medium. The respective opening connects the housing interior in fluid communication to an exterior space not enclosed by the housing so that an air flow is enabled between the housing interior and the exterior space.

A filter cartridge for an air cleaner assembly is disclosed. The filter cartridge can include a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter. The filter cartridge can also include a circumferential shell surrounding at least a portion of the media pack outer perimeter. A radial flange extending from the circumferential shell proximate the media pack inlet end can also be provided. The flange can define a plurality of openings that are configured to receive protrusions on a housing body of the air cleaner assembly. The interaction between the protrusions and openings operates to ensure a secure seal between the housing body and the seal member.

An active field polarized filter includes a scrimless filter media that includes a mixture of polypropylene fibers with polymethaphenylene isophtalamide fibers. This mixture may be in the form of a nonwoven material having a weight ratio of polymethaphenylene isophtalamide fibers to polypropylene fibers ranging between 5:95 and 50:50, and even more preferably between 10:90 and 30:70.
