Collection: Ultraviolet Purifiers

Ultraviolet purification is a proven technology (EPA approved) that can protect your family from waterborne disease-causing microorganisms, such as bacteria, viruses, algae, and fungi. Ultraviolet (UV) disinfection works by delivering concentrated amounts of UV light energy to the reproductive mechanism of the microbe, effectively killing it. As water passes through the UV chamber, it instantly disinfects it. The only homeowner maintenance is to replace the bulb once per year.

Chlorine is widely used as a disinfectant, but it has several drawbacks. Chlorine requires constant monitoring for proper dosage, as well as a holding tank to allow proper contact time. Chlorine reacts with naturally occurring organic matter in water to form byproducts such as chloroform, a known carcinogen. In addition, chlorine leaves an objectionable taste and odor in the water. UV purifiers have none of these drawbacks - it disinfects without chemicals.

Two types of UV purifiers are available - point-of-entry, which installs on your main water line to purify all the water in your home, and point-of-use, which purify water at a single faucet.

Manufactured by Viqua point-of-use ultraviolet purifiers can be used alone, or with combined with other filter configurations. See our whole house water filters. The stainless steel chamber has 1/4" MNPT ends. It carries a 10-year warranty on UV Reactor, 3 years on Ballast, and 1 year on lamps.

Sterilight / Viqua point-of-entry ultraviolet purifiers connect to the main water line to purify the entire household water - all faucets, showers, and baths. The stainless steel water chamber has 3/4" MNPT ends. The control module/monitor can be installed in a convenient location.
To determine your peak flow rate, time how long it takes to fill a 5-gallon bucket at an unrestricted outlet, such as an outside hose bib. You can then calculate the gallon per minute flow. For example, if it took 30 seconds (0.5 minutes) to fill, that would be 10 gallons per minute (5 divided by 0.5).

Note: it is recommended that a 5 micron or better sediment prefilter be installed ahead of the purifier. Water that is over 7 grains per gallon hard should be softened ahead of the purifier. Iron should be less than 0.3 ppm.
