A filter element comprising: a first pair of opposing walls extending along a longitudinal axis of the filter element; a second pair of opposing walls extending along the longitudinal axis, the second pair of opposing walls coupling the first pair of opposing walls to one another, wherein the first and second pairs of opposing walls create a flow passage between an inlet end of the filter element and an outlet end of the filter element in a direction substantially aligned with the longitudinal axis; filter media associated with the filter element and 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 opposing walls of the first pair of opposing walls, the wedge element being configured to cooperate with an interior surface of a filter housing configured to receive the filter element, wherein each of the opposing walls of the first pair of opposing walls has a respective outlet edge at the outlet end of the filter element, wherein the respective outlet edges extend at a first oblique angle ( α) with respect to the longitudinal axis, and wherein the filter element further includes a seal member associated with the outlet end of the filter element, the seal member being configured to provide a substantially air-tight seal between the outlet end of the filter element and an outlet shoulder of said filter housing, wherein the wedge element extends at a second angle ( β) with respect to the longitudinal axis, the first and second angles being different from one another, wherein the wedge element includes at least one of a groove, a ridge, a shoulder, or one or more protrusions, and wherein the wedge element is configured to cooperate with a wedge receiver of said filter housing to compress seal member against outlet shoulder of said filter housing. a first pair of opposing walls extending along a longitudinal axis of the filter element; a second pair of opposing walls extending along the longitudinal axis, the second pair of opposing walls coupling the first pair of opposing walls to one another, wherein the first and second pairs of opposing walls create a flow passage between an inlet end of the filter element and an outlet end of the filter element in a direction substantially aligned with the longitudinal axis; filter media associated with the filter element and 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 opposing walls of the first pair of opposing walls, the wedge element being configured to cooperate with an interior surface of a filter housing configured to receive the filter element, wherein each of the opposing walls of the first pair of opposing walls has a respective outlet edge at the outlet end of the filter element, wherein the respective outlet edges extend at a first oblique angle ( α) with respect to the longitudinal axis, and wherein the filter element further includes a seal member associated with the outlet end of the filter element, the seal member being configured to provide a substantially air-tight seal between the outlet end of the filter element and an outlet shoulder of said filter housing, wherein the wedge element extends at a second angle ( β) with respect to the longitudinal axis, the first and second angles being different from one another, wherein the wedge element includes at least one of a groove, a ridge, a shoulder, or one or more protrusions, and wherein the wedge element is configured to cooperate with a wedge receiver of said filter housing to compress seal member against outlet shoulder of said filter housing.
