A filter element comprising: a tubular member having a longitudinal axis and including: a partition at least partially defining a first chamber and at least partially defining a second chamber, the partition extending longitudinally in the tubular member and being configured to prevent flow communication between the first chamber and the second chamber within the tubular member; an end portion at least partially defining an inlet port configured to provide flow communication into the first chamber, and at least partially defining an outlet port configured to provide flow communication from the second chamber; at least one outlet aperture in the tubular member configured to provide flow communication out of the first chamber; at least one inlet aperture in the tubular member configured to provide flow communication into the second chamber; and a cover portion at the end portion of the tubular member, the cover portion extending from the partition, wherein the cover portion is configured to at least partially cover a longitudinal end of the second chamber with respect to the longitudinal direction; wherein the filter element further comprises a filter medium comprising a first portion and a second portion, wherein the first portion is located exterior and adjacent to the at least one outlet aperture and the second portion is located exterior and adjacent to the at least one inlet aperture, further wherein the filter element is configured such that fluid passing through the filter element from the inlet port to the outlet port passes through both the first chamber and the second chamber, further wherein the tubular member includes an exterior wall extending in the longitudinal direction, and wherein the outlet port is an outlet aperture in the exterior wall of the tubular member, further wherein the cover portion is configured to substantially prevent flow of fluid into the second chamber without first passing through the first chamber. a partition at least partially defining a first chamber and at least partially defining a second chamber, the partition extending longitudinally in the tubular member and being configured to prevent flow communication between the first chamber and the second chamber within the tubular member; an end portion at least partially defining an inlet port configured to provide flow communication into the first chamber, and at least partially defining an outlet port configured to provide flow communication from the second chamber; at least one outlet aperture in the tubular member configured to provide flow communication out of the first chamber; at least one inlet aperture in the tubular member configured to provide flow communication into the second chamber; and a cover portion at the end portion of the tubular member, the cover portion extending from the partition, wherein the cover portion is configured to at least partially cover a longitudinal end of the second chamber with respect to the longitudinal direction; wherein the filter element further comprises a filter medium comprising a first portion and a second portion, wherein the first portion is located exterior and adjacent to the at least one outlet aperture and the second portion is located exterior and adjacent to the at least one inlet aperture, further wherein the filter element is configured such that fluid passing through the filter element from the inlet port to the outlet port passes through both the first chamber and the second chamber, further wherein the tubular member includes an exterior wall extending in the longitudinal direction, and wherein the outlet port is an outlet aperture in the exterior wall of the tubular member, further wherein the cover portion is configured to substantially prevent flow of fluid into the second chamber without first passing through the first chamber.
