Ultraviolet light (UV) systems are good at killing bacteria but they do not filter anything! These UV systems also have a maintenance issue, the lights have a clear glass tube that surrounds the light bulb from water. If the glass leaks and the water hits the light bulb the system is done. That very seldom happens but the real problem is that the glass tube sleeve collects dirt which stops the full spectrum of the UV light from penetrating the glass and killing the microorganisms in the water. This glass needs to be removed and cleaned every six months to be effective and the UV light needs replacing every year. The Nano Ceram does not have any of those issues.
The full line of Nano Ceram water filters reduces thousands of contaminant's, including bacteria, virus and drugs, with no power, no moving parts and no chemicals.
