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.
