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.
