Abstract
An air cleaner assembly includes a filter housing extending axially along a longitudinal axis and a cover. The filter housing includes at least one sidewall (e.g., an annular sidewall) extending between a first housing end and a second housing end and a retainer formed proximate at least one of the first housing end and the second housing end. The cover is removably coupled to at least one of the first housing end and the second housing. The cover includes a handle assembly having a latch configured to releasably engage the retainer of the filter housing. The filter element includes filter media and is axially insertable into the filter housing when the cover is removed from the filter housing.

An air cleaner assembly comprising:
- a filter housing extending axially along a longitudinal axis and comprising:
- at least one sidewall extending between a first housing end and a second housing end;
- and
- a retainer formed proximate at least one of the first housing end and the second housing end;
- and
- a cover removably coupled to at least one of the first housing end and the second housing end, the cover comprising:
- a flexible latch portion positioned on an axial surface of the cover, the flexible latch portion having a protrusion configured to releasably engage the retainer of the filter housing, and
