Abstract
Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly cannot be fully closed, even if a cartridge is nested therein, and appears to be sealed, unless that cartridge is a proper one for the system of concern. The effect is to prevent an inappropriate cartridge, that does not properly seal, from being inadvertently installed in the assembly.

An air filter cartridge comprising:
- (a) a media pack having a rectangular outer perimeter and opposite inlet and outlet flow faces;
- (i) the media pack rectangular outer perimeter having a first pair of opposite ends and a second pair of opposite sides;
- and
- (ii) a first pair of panels covering the media pack first pair of opposite ends;
- (b) a housing engagement member including a seal arrangement having:
- a seal member extending around the media pack first pair of opposite ends and the media pack second pair of opposite sides, and having a seal surface located on at least one of an upstream side of the seal member or a downstream side of the seal member;
- a seal support portion;
- and, a receiving trough between at least a portion of the seal member and the media pack;
- and,
- (c) a receiving member of an air cleaner security, housing closure, inhibition arrangement positioned in the housing engagement member, wherein
- the receiving member is a pocket having an opening and a recess, wherein the pocket is located along one of the media pack first pair of opposite ends, the receiving member opening is located radially interiorly from the seal surface, and the seal surface located radially outwardly from the pocket extends in a straight path.
