Abstract
A filter element may include first and second pairs of opposing walls extending along a longitudinal axis of the filter element. The first and second pairs of opposing walls may create a flow passage between an inlet end and an outlet end of the filter element. The filter element may further include filter media configured to separate particulates from air flowing through the flow passage, and a wedge element associated with an exterior surface of at least one of the first pair of opposing walls. The wedge element may be configured to cooperate with an interior surface of a filter housing configured to receive the filter element. Outlet edges of the opposing walls of the first pair of opposing walls may extend at a first oblique angle with respect to the longitudinal axis, and the wedge element may extend at a second oblique angle with respect to the longitudinal axis.
