Publication number: 20150013292Abstract: An air cleaner having a housing body and a removable cover and a filter element, in which the cover and the filter element rotationally interfere with each other by engagement between an inside surface of the cover and an outer radial periphery of the filter element. A filter element includes a pair of end caps, filter media, and an outer wall on the end cap circumscribing the filter media, in which the outer wall is non-circular. A method of installing a filter element into a housing includes orienting a cover over an element and a housing body by engaging an inside surface of the cover and an outer radial periphery of the filter element to rotationally interfere with each other.Type: ApplicationFiled: June 16, 2014Publication date: January 15, 2015Inventors: Paul R.
