The ultraviolet purifier takes a page from the technology of nature, as the UV rays penetrate bacteria, disinfecting your water while sterilizing 99.99% of harmful microorganisms. This neutralizes harmful bacteria that can create waterborne illness within your home. Unlike chlorine, UV does not alter the taste or odor of water and will not impart any toxic by-products. Treating your water supply with UV disinfection is not only more effective than traditional treatments, but it is also environmentally responsible.
