Abstract

The present disclosure relates to filter assemblies. The features described and characterized are typically applied in gas (for example, air) cleaner assemblies. A typical use is in air cleaner assemblies for vehicles or other equipment. The techniques described relate, at least in part, to provision of assemblies with preferred configurations for convenient servicing and operation, while ensuring a proper cartridge is appropriately positioned, oriented and secured for use. Many of the techniques relate to arrangements in which features at opposite ends of a housing and/or cartridge are eccentrically positioned as described.
