Watkins highly recommends the Freshwater III Ozone purification Accessory (pn 72603) for your Hotspring® spa. The Freshwater III ozone system utilizes Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by competing ultraviolet light (UV) ozone systems. 

The ozone works in harmony with your regular sanitisation routine as the spa 
water passes through the generator and is zapped with ozone to kill off the bacteria. More information on your ozone and how to care for it can be found in your Owners Manual.


The Ozone generator uses an electrical current to generate ozone and injects an extra oxygen atom to produce O3 that when it comes in to contact with any organic matter, including bacteria and viruses the atom leaves the oxygen and oxidizes the organic matter to kill it. The only byproduct of this process is oxygen O2.

The benefits of having an ozone.

  • Natural ozone is a form of oxygen and is a very powerful spa sanitiser.
  • Automatic sanitation that helps to provide an easier way to maintain your hot tub water.
  • Ozone reduces the need for chemicals such as chlorine and bromine by appx  60 – 90%.
  • Ozone kills up to 99.99% of dangerous microbial agents like bacteria and viruses on contact.
  • Ozone oxidizes the widest range of organic materials, including human fluids, of any spa sanitizer.
  • The only byproduct of ozone is ordinary oxygen – and oxygen actually contributes to the sparkling clarity of your hot tub water.
  • Has a life expectancy of up to 5 years.
