Filter assemblies utilizing full cross-section

A filter element configured to be disposed within a filter housing having an inner cross-section that defines a maximum inner cross-sectional distance, the filter element comprising:

• a filter media pack, at least a portion of the first filter media pack having an outer cross-section defining a maximum outer cross-sectional distance that is substantially equal to the maximum inner cross-sectional distance of the filter housing;
• and
• a support structure coupled to at least one longitudinal end of the filter media pack distal.

A filter element configured to be disposed within a filter housing having an inner cross-section defining an inner cross-sectional distance, the filter element comprising:

• an axial flow filter media pack, a channel defined through the axial flow filter media pack along a longitudinal axis of the filter element, the axial flow filter media pack configured to allow a fluid to flow therethrough along the longitudinal axis in a first direction and be filtered, the filtered fluid flowing through the channel in a second direction opposite the first direction towards the outlet, at least a portion of the axial flow filter media pack having an outer cross-section defining an outer cross-sectional distance that is substantially equal to the inner cross-sectional distance of the housing;
• and
• a support structure coupled to at least one end of the axial flow filter media pack.
