Reserve Filter Systems, of Twinsburg, Ohio, offers gradient density filter cartridges to fit BB housings. The melt-blown, microfiber filter cartridges are made from FDA compliant and NSF-certified materials. They’re manufactured using a microfiber process that thermally bonds pure polypropylene microfibers with lower density at the outside surface and progressively higher density toward the center. This results in a cartridge that provides high flow rates, high dirt-holding capacities and fewer filter change-outs.
