UV light has germicidal properties

Ultraviolet Sterilization Effectively Kills Bacteria, Viruses and Parasites such as Cryptosporidium & Giardia. Chlorination only keeps bacteria at low levels. The difference between Chlorination and UV is the difference between Sanitization and Sterilization. UV Sterilization provides complete protection for your family, employees and customers, from Microbes in your water.

It is estimated that seven to 30 million Americans develop a gastrointestinal illness each year, from drinking contaminated water. The Center for Disease Control and Prevention estimates 900 to 1,000 deaths occur from microbial illnesses from US drinking water. You can Protect Your Family, Company and Customers health, simply, easily and inexpensively by adding a UV Sterilization System to your home.

How does Ultraviolet Sterilization Work?

The germicidal energy of ultraviolet light destroys harmful microorganisms by attacking their genetic core (DNA). This powerful dose of UV light eliminates their ability to reproduce, and the organisms simply die.

Water is purified by running it through a watertight chamber that contains an ultraviolet lamp. As water flows past, microorganisms are exposed to a lethal dose of germicidal UV energy.

Purification with the UV Max is a safe, natural process that adds no chemicals and does not affect the taste or odor of your water.

Specialized, high output UV lamps maximize the output of germicidal UV energy.
