A common solution to purify spas and hot tubs is adding chemicals like chlorine. Although chlorine kills most microorganisms, they are also the cause of the most issues for bathers (eye-, skin irritation, breathing difficulties). In addition, they have a big negative effect on the materials in and around the spa or hot tub.


UV-C technology is becoming a standard for water treatment in pool filter systems. The problem for spas en hot tubs has been that the UV units for pools are to large. Blue lagoon developed a few UV-C units especially for spas and hot tubs were there is limited space but still high disinfection needed. The units provide safe, clean and healthy water to relax in.
