The Ultra Biolyte™ Counter Top Ultraviolet Purifier is designed to be both portable and cost efficient. It features a three stage filtration system. First the water is filtered down to 20 microns to filter out any sediment in the water. Then the water passes through a 1-2 micron compressed block of activated carbon to remove chlorine, taste, odor, and chemical impurities from the water. The water then enters a stainless steel disinfecting chamber where it is exposed to high levels of ultraviolet light which attacks harmful microorganisms, bacteria, viruses, and sterilizes them. The 12 volt design plugs into any standard household outlet using an adapter, and is ideal for campers and boats also.
