Replacement Ozone generator (fits all H2O models)

This is a direct replacement ozone for all the H2O hot tubs range, these should be changed every 2-3 years for maximum spa performance.

The spa ozonator is an ozone generator that injects dissolved ozone into the spa water where it is one of the most powerful oxidizing disinfectants on earth, yet virtually undetectable by human touch. This natural form of oxygen combines with organic matter of all kinds to kill or neutralize it. Ozone is 200 times more powerful than chlorine and up to 99.99% effective against bacteria and viruses that can lurk in a hot tub. As an added benefit, the only byproduct of ozone is ordinary oxygen – no chemical residues.
