Pure water starts with the purest of technology.

You hope your water quality is never in question, but if it is, you want the assurance of our VIQUA Systems. Engineered to eliminate variable water conditions, this environmentally conscious system uses ultraviolet light to clean the water flowing through your home. Easy to maintain, you can trust that the water your family consumes is safe and free from potentially harmful bacteria and viruses.

Peace of Mind

Enjoy clean, safe, purified water distributed to every tap in your home.  Aging water infrastructures in many cities can lead to an increased risk of contamination.  Rest assured you’re protected from the potential of contaminated water supplies.

Protect Your Health

Eliminate the potential health threat microorganisms pose to you and your family.  VIQUA systems provide a safe solution against chlorine resistant microorganisms such as Cryptosporidium and Giardia, which cause thousands of documented health cases each year.

Environmentally Friendly

UV treatment is a safe, natural process. No chemicals are used and the taste of your water is not affected in any way. UV treatment promotes low energy consumption, about the same as a 40-watt light bulb.

Minimal Maintenance

Simple annual replacement of the UV lamp and occasional cleaning of the quartz sleeve that surrounds the UV lamp is all you’ll need to do to keep your VIQUA system working properly. BACK TO TOP
