Spa & Hot Tub Ultraviolet (UV) Systems

Shift Away from Hot Tub Chemicals for a Safer Spa

Just the thought of soaking in a spa or hot tub after work, during a vacation or with a loved one can be relaxing. While warm water therapy can be great for your stress levels and your sore muscles, hot tubs and spas can turn into a toxic soup of chemicals over time.

Why are Hot Tubs More at Risk Than Pools?

Higher temperatures, smaller water volume, and a higher bather load increase the risk of contaminants. SpectraLight hot tub disinfection systems harness the power of ultraviolet light to eliminate waterborne pathogens, lower chemical levels, and eliminate chlorine by-products. The result is a hot tub that is safe, healthy, and easy to manage.

Are Hot Tubs Safe?

Hot tubs and spas rely on the same chemicals that have been in use for more than 40 years. It's no surprise that some of these chemicals will burn your eyes or irritate your skin. But you may not know that the bubbling water can be full of bacteria and other pathogens. Now researchers have proven that pool and hot tub chemicals increase the risk of allergies, asthma, and even some forms of cancer. We share with you three alarming studies that are turning the pool and hot tub industry upside-down.

Hot Tub Disease

Hot tub diseases are more common than you think. The hot tub can be home to bacteria, viruses, and fungi. Bacteria such as mycobacteria, E. coli, and pseudomonas aeruginosa can thrive in hot tubs, causing infections to unsuspecting users. Contact with infected people in the spas and hot tubs can lead to both bacterial and fungal infections— and herpes virus infections.

How Hot Tub and Spa UV Works

Our UV spa systems were built on a visionary model for the pool and spa industry. The science behind our UV spa models was inspired by municipal drinking water treatment. As water passes through the disinfection chamber, a high intensity UV germicidal light ray targets the DNA and RNA of bacteria, viruses, algae, parasites, cysts and more.
