A water filter will sterilize and detoxify water by taking advantage of two technologies in the field of water disinfection and detoxification—ultraviolet “C” (UVC) and photocatalytic oxidation (PCO). The water filter includes a filter body that contains a water inlet, a flow header and granular activated carbon. A UVC lamp sleeve extends into the filter body into which a UVC lamp is disposed. The filter body, the UVC sleeve and the granulated activated carbon are coated with titanium dioxide, turning all these surfaces into a semi-conductor that triggers a powerful PCO process when UVC photons comes in contact therewith. The carbon media adsorbs organic compounds present in the incoming water, allowing the PCO and UVC ample time to complete the oxidation process. Continuous break down of organic compounds by PCO and UVC allows the carbon media to self-regenerate itself indefinitely. The technology is scalable to any size and application.
