Ultraviolet light disrupts the DNA structure of bacteria and other living organisms (aka: organic contaminants) sometimes found in drinking water. Cooler temperatures in water storage tanks contained in water coolers can create ideal conditions for biofilms and other types of ‘slime’ to build up and reproduce — especially since the water also contains no sort of disinfectant or sanitizing agent (i.e. chlorine).

UV sanitation stops biological contaminants from reproducing if present in drinking water. Granted nothing SHOULD have had a chance to get into the ‘guts’ of your water cooler in the first place, but if it did, the fact that the crystal clear, pristine water you expect that machine to produce contains nothing to prevent a colony of bacteria from breeding makes inside your water cooler a great place to live, breed and raise a family.

UV water sterilizers for home use?

The simplest UV systems for home use typically function as inline water filters. As an example, Crystal Quest manufacturers an easy-to-install home uv water sterilizer available in three sizes, each with a different flow rating: 6, 8 and 12 gallons per minute.

Many people choose to add an ultraviolet water sterilizer to existing whole house water filter systems or any other filtration system where bacteria could possibly exist.

A good number of folks with well water also choose to install a UV sterilizer system in their homes. After all… well water does come from an unfiltered, untreated source that could very easily become with bacteria.

Other places where a UV sterilizer would work well?

The hard glass germicidal lamps in UV sterilizer systems provide a 99.99% reduction of bacteria, virus and protozoa. They accomplish that feat without the use of potentially harmful chemicals. Environments such as health care facilities (i.e. doctor offices, hospitals, dental offices, etc.) and residences with small children, elderly or immunocompromised individuals can also definitely benefit from the use of UV sterilization on their water supply.
