A filter cartridge for installation within a compatible pressure vessel is provided. The filter cartridge comprises a filter head comprising a fluid inlet and a fluid outlet, a filter media attached to the filter head, the filter media being in fluid communication with the fluid inlet and the fluid outlet. The filter cartridge further comprises a polymeric film attached to the filter head and forming a fluid-tight casing around the filter media, the polymeric film comprising an inner film wall facing the filter media and an outer film wall facing the pressure vessel. One or more depressions in the outer film wall create one or more fluid passages between the polymeric film and the pressure vessel when the filter cartridge is installed in the pressure vessel.
