    Abstract: An air cleaner assembly is disclosed, along with related methods. In one aspect, the air cleaner assembly has a housing including a housing body and a removable cover that together define an interior volume for holding a filter cartridge. The housing can include a first part of a first connection arrangement. The air filter cartridge can include a second part of the first connection arrangement. In one aspect, the first and second parts can be secured together place the air filter cartridge in a latched position by moving the air filter cartridge in a first direction. In one aspect, the first and second parts can be disconnected from each other to place the air filter cartridge in an unlatched position by moving the air filter cartridge in the first direction. The air cleaner assembly can include a second connection arrangement securing the air filter cartridge to the housing cover such that the housing body and housing cover are secured together.

    Abstract: The technology disclosed herein relates to a filter assembly. The filter assembly has a double-sided adhesive layer having a first side and a second side and defining a filter opening. A first membrane extends over the filter opening and is directly coupled to the first side of the double-sided adhesive layer about the filter opening. An adsorbent element is directly coupled to the first membrane, where the adsorbent element and the first membrane are coextensive. A second membrane encapsulates the first membrane and the adsorbent element. The second membrane is directly coupled to the first side of the double-sided adhesive layer around the first membrane and adsorbent element.

    Abstract: An air filter element includes a filter arrangement, an elbow, and a filter element seal member. The filter arrangement includes a filter media pack having a dirty air inlet and a clean air outlet, wherein air flowing through the clean air outlet flows in a first axial direction and the clean air outlet defines a filter arrangement cross sectional area. The elbow has a first end constructed to extend from the filter arrangement clean air outlet, a second end wherein air flowing through the second end flows in a second axial direction, and an air flow enclosure extending from the elbow first end to the elbow second end. The air flow enclosure includes an air deflector constructed to direct air from the first axial direction to the second axial direction, wherein the second axial direction is different from the first axial direction, and an interior volume between the elbow first end and the elbow second end. The filter element seal member is located on the elbow second end, wherein the filter element seal member is constructed to seal to a clean air intake, the filter element seal member located on the elbow second end defining a seal member cross sectional area. The filter element can be characterized as having a ratio of the seal member cross sectional area to the filter arrangement cross sectional area of at least 0.5. The filter element can have a z-filter media pack for a pleated media pack. The air filter element can be arranged in an air cleaner.
