A filter cartridge includes a substantially cylindrical filter media having a first end and a second end wherein the second end has an opening adaptable to receive a fluid outlet. The filter media is adapted to allow fluid to pass from an exterior of the filter media to an interior space of the filter media. A divider is positioned adjacent to the exterior of the filter media, and the divider has a closed end connected to the first end of the filter media and an open end that is longitudinally-spaced from the second end of the filter media such that at least a portion of the filter media located adjacent to the second end of the filter media is not directly adjacent to the divider. The divider extends a majority of the distance from the first end to the second end of the filter media.
