## Abstract

An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

## Claims

### Claim 1

A side-load air filter cartridge comprising:
a. a media pack configured for installation into a side opening of an air cleaner housing, the media pack extending along a longitudinal axis and defining an outer perimeter; and
b. a first seal arrangement operatively positioned with respect to the media pack, the first seal arrangement defining a first axial seal surface facing generally towards the inlet flow end or outlet flow end, a portion of which is arranged at an oblique angle to the longitudinal axis;
c. wherein a second segment of the first axial seal surface deviates away from a first segment of the first axial seal surface in an axial direction such that the first axial seal surface second segment falls outside of a plane defined by the first axial seal surface first segment.

### Claim 2 (depends on 1)

The side-load filter cartridge of claim 1, wherein the first axial seal surface first segment is disposed at a first oblique angle and the first axial seal surface second segment is disposed at a second oblique angle, wherein the second oblique angle is greater than the first oblique angle.

### Claim 3 (depends on 1)

The side-load air filter cartridge of claim 1, wherein the first segment of the first seal arrangement crosses a plane defined by the media pack outlet end.

### Claim 4 (depends on 1)

The side-load air filter cartridge of claim 1, further comprising a second seal arrangement operatively positioned with respect to the media pack, the seal arrangement defining a second axial seal surface facing away from the first axial seal surface, wherein the second axial seal surface is arranged at an oblique angle to the longitudinal axis.

### Claim 5 (depends on 4)

The side-load air filter cartridge of claim 4, wherein a second segment of the second axial seal surface deviates away from a first segment of the second axial seal surface in an axial direction such that the axial seal surface second segment falls outside of a plane defined by the axial seal surface first segment.
