Clean Shield Lamp | For UV-250

A UV lamp is the heart of your water disinfection system. It uses ultraviolet (UV) light—a specific wavelength of light energy—to neutralize harmful microorganisms like bacteria, viruses, and protozoa.

Scientifically, UV light works by damaging the DNA and RNA of these organisms, preventing them from reproducing or causing illness. This process happens in a matter of seconds as water flows past the UV lamp inside the system’s chamber.

When working properly, a UV lamp can inactivate up to 99.99% of waterborne pathogens—without adding any chemicals, changing the taste of your water, or leaving behind harmful byproducts.

It’s a safe, powerful, and eco-friendly way to protect your home’s water—and your health.

The technology of UV disinfection uses a translucent lamp that emits UV radiation which is created inside the lamp by an arc between the two filaments of the lamp.

This electronic arc is vaporizing a bead of mercury inside the lamp, and once the mercury is used up, the lamp will only shine blueish, but not emit UV rays any more so it will have to be replaced.

Our UV lamps are rated for a lifetime of 11,000 hours, which is a bit more than 1 year for a light that is on all the time 24/7/365.
