Camco's Evo Water Filter reduces bad taste, odors, sediments, bacteria, chlorine, and much more. It includes a filter housing, (1) extension hose, and (1) replaceable premium spun polypropylene filter cartridge. Filtration begins with water traveling through a porous shell with openings no greater than 5-microns in diameter. Filtered water then passes through a bed of KDF and GAC (Granulated Activated Carbon) for further filtration and bacteria control. The result is fresh, clean, great-tasting drinking water straight from your tap. For exterior use.
