The water purification cartridge treats water with a halogen liberated from halogenated hydantoinyl resins and polymers, resulting in the safe, complete, and economical purification of non-potable water at low flow rates typically found in gravity feed filtration systems and at water pressures of less than 1 psig. The cartridge of the invention purifies non-potable water of bacteria, viruses, and some protozons without the need for additional power sources or risk to the consumer for exposure to chemicals that have been identified to have harmful, long-t...


The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A gravity fed water purification cartridge, comprising: an inlet head cap configured to be coupled to a prefilter, wherein said inlet head cap provides an inlet for untreated water; a ring member in fluid flow communication with the inlet head cap, wherein said ring member is configured to evenly distribute the untreated water to a purification medium; a purifier vessel in fluid flow communication with the ring member, wherein said purifier...
