Abstract
A filter assembly comprises a filter element and a housing. The filter element comprises a filter media, and an alignment feature positioned on at least a portion of an outer surface of the filter media. The alignment feature comprises an alignment channel. The housing defines a housing internal volume. At least a portion of the filter element is positioned within the housing internal volume. The housing comprises an alignment protrusion extending axially from a housing inner surface towards the filter element so as to mate with the alignment channel. The alignment feature comprises a ring member positioned circumferentially around the filter media at a filter media first end proximate to the housing, and a filter baffle extending from the ring member. The filter baffle is circumferentially positioned on at least a portion of the outer surface of the filter media and defines the alignment channel.
