According to the present disclosure, air cleaner assemblies, housings, serviceable filter cartridges and features, components, and methods, relating thereto are disclosed. In general, the features relate to systems that are configured to aid in inhibiting an improper cartridge from being installed in an air cleaner housing, during servicing. A variety of features are characterized, and in many examples, the cartridge includes a seal arrangement having radially directed seal surface with at least a first non-wavy or non-projection/recess section and a second wavy or projection/recess section. Examples are shown and described in detail.

Filter cartridges; air cleaner assemblies; housings; features; components; and, methods

According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided with variations therein, to advantage. These variations can be in either or both of an outer peripheral edge surface and a housing seal engagement surface. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.

The disclosure concerns air cleaners. Preferred air cleaners are shown which include a housing and a removable and replacement primary filter cartridge. Optional and advantageous features are shown. The preferred primary filter cartridge is conical in shape. A preferred optional safety or secondary filter cartridge is shown. Preferred methods of assembly and use are provided.

Air cleaner; replaceable filter cartridges; and, methods

A filter element, a safety element and fluid cleaner assembly. The fluid cleaner assembly generally includes a housing having a cover and a primary fluid cleaner section. The element generally comprises z-filter media, arranged in a straight through configuration, and an axial seal gasket positioned to extend continuously around at outer perimeter of the straight through flow construction. The fluid cleaner assembly can have a precleaner positioned therein. Methods of assembly and use are provided.
