Dual Defense Purification System

Clearwater Spas Clean Light™ UVC and ozone purification system is combined into a Dual-Unit – DDPS™


This combination of an Ultra-Violet germicidal (UVC) and integration of Mazzei-injected ozone offer the ultimate in water purification.  Clearwater Spas DDFS™ is a powerful disinfection system that breaks the vicious cycle of hot tub chemical use, reducing the need for high chemical doses.  This system helps destroy bacteria, viruses, algae, yeasts, unused oxidizers, and other contaminants; reduces odor and chloramines, prolongs equipment life, reduces maintenance time and cost, and purifies naturally.
The Clean Light UVC and Ozone functions as a complete purification solution when used along with the normal filtration functions of hot tubs and monitoring of water chemistry.

The Clean Light™ UVC and ozone provides enhanced sanitation through:

  • UVC water irradiation and sterilization of micro-organisms
  • Oxidation of pathogens, viruses and molds through ozonation
  • Advanced oxidation process (AOP) via ozone reaction with UVC light
  • Reduction or elimination of chloramines in the spa water
  • Dual and redundant sanitizing processes (UVC and ozone)
  • Higher levels of oxidation in the water due to AOP and UVC mixing chamber
  • Elimination of dead-zone smells above the water surface when cover closed

This system drastically reduces chemical use and provides easier spa water maintenance.  This environmentally friendly solution also prolongs the life of your spa shell and equipment.

Ultraviolet UVC light, how it works.

The sun emits invisible light – ultraviolet light. Through leading edge technology, this natural phenomenon is reproduced inside the sanitizers of the Clearwater UVC System Technology lamps. At approximately 254 nanometers, the optimum wavelength for destroying micro-organisms (viruses, bacteria, algae, yeast, mold, etc.), these UVC rays penetrate and disrupt their DNA, permanently deactivating germ cell metabolism so they cannot reproduce.

Phase 1

The UVC light kills the micro-organisms

Phase 2

Ozone oxidizes (eliminates) the destroyed micro-organisms
