A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path; and a tube sheet that is supported across the filter housing, that is disposed just before the outlet zone and that provides the support for the plurality of filter elements. The plurality of filter elements are disposed in an array and includes bridging members or elements that connect between adjacent filter elements, and that forms with the filter elements, a closed interstitial space between adjacent filter elements for liquid flow; a nanoscale barrier on interior surfaces, including that of the regenerative media itself, providing a mechanism to disrupt the cell wall of microscopic viruses and organisms.

A filter assembly for filtering liquid includes a filter housing and a filter cartridge disposed in an enclosed space of the filter housing. The filter housing including a cap affixed to the bowl to form the enclosed space. The cap including a fluid inlet port, a fluid outlet port, and a gas venting port for the enclosed space. The filter cartridge includes radial projections disposed in slots of the bowl blocking rotation of the filter cartridge relative to the bowl. A method of making a filter assembly includes inserting a filter cartridge into a bowl, and affixing the cap to the bowl.
