The quality of drinking water affects our well-being and the germicidal light is proven to destroy viruses, bacteria, protozoa, molds, and other harmful pathogens. The lamp features a wavelength with lethal effectiveness of  253.7nm that helps disrupt harmful microorganisms' DNA and renders them harmless. Measuring 33.19 inches in length, the UVC lamp has a long-lasting life rate of 10,000 hours, you get a 12-month worry-free water sanitizing operation. After that time the light may still be visible but the germ-destroying ability of the compatible UV light bulb may have been reduced so we recommend you replace the lamp bulb.
