Abstract: An air cleaner assembly is described and shown which includes a housing having an air flow inlet, an air flow outlet and a housing body and access cover. A serviceable filter cartridge is positioned within the housing. A projection/receiver arrangement providing for engagement between the cartridge and the access cover is provided. The projection/receiver arrangement can be configured in a manner that inhibits both cantilevered motion and rotational motion of the cartridge, once installed. An example projection/receiver arrangement is provided, which includes a serpentine receiving groove on the access cover and a serpentine projection on the filter cartridge.

Abstract: An air cleaner assembly and components therefor are provided. Features are described providing for a cantilevered support of a filter cartridge contained therein, and also, in some examples anti-rotational support. Also, a supported housing seal is shown. A filter cartridge arrangement is described and shown. Methods of assembly and use are also described.
