Ultraviolet Water Purifiers

If you are looking for a system that can purify your water without using chemicals, you should consider installing an ultraviolet water purifier. Ultraviolet light is part of the light spectrum; ultraviolet light with wavelengths from 100 to 280 nanometers is germicidal, meaning that it destroys the DNA of bacteria, viruses and other pathogens. By exposing the microbes in water to the right dose of ultraviolet light for the correct amount of time, water can be inexpensively purified in an easy to maintain system.

Ultraviolet light can be used to purify household water used for drinking, ice making, cooking, bathing, and washing. It is especially useful where water supplies depend on wells or cisterns. It can be used on aircraft, boats and recreational vehicles, for swimming pools and hot tubs, and for aquariums. If you are thinking of buying an ultraviolet water purifier, consider the following:

  • Purifiers made from stainless steel will last longer than those made from plastic, as the ultraviolet light damages the plastic. Also look for purifies with processing chambers that are easy to drain in place.
  • Better units have a light that glows to show that the ultraviolet germicidal lamp is on. This lamp must be periodically replaced. Look for those that last for about a year and that are easy to replace when necessary. The easiest systems do not require any tools, and replacement of the lamp can be accomplished in less than five minutes.
  • Ultraviolet light will not remove foreign particles from the water. For this, you will need some form of filtering.

Systems that come fully assembled and that have been pressure tested are the easiest to install. Check to make sure that the system meets U.S. Public Health guidelines before purchasing.
