All USA Spas are be equipped with the Del Ozone Natural Spa Sanitizing System. This system utilizes the latest ozone technology and injects ozone consisting of three oxygen atoms, directly into the spas water to kill bacteria. The ozone sanitation is completely biodegradable and 100% natural with the only byproduct being oxygen.
 

Ozone used in combination with a residual amount of Chlorine or Bromine can effectively provide a clean, safe bacteria-free spa and dramatically reduce chemical use.
