From the 1st January 2025 the new law across Europe regarding corona discharge ozonators is basically : we can sell you an ozonator but you are not allowed to fit it to your spa.

We do not pass on your details to anybody about you purchasing an ozonator.

Ozone is active oxygen. Ozone (at the levels used in hot tubs) is harmless and reacts quickly with contaminants in water, making it ideal for use in hot tubs to help purify the water. Ozone is generated by ultraviolet (UV) light or by corona discharge (CD). Older units found in hot tubs use UV light ozonators, now largely replaced by the more efficient CD chip units. Ozone is very gentle to skin and eyes and is pH neutral.
