Ozone is approved by both USDA and FDA as GRAS (Generally Recognized as Safe).Exposure to a high concentration of Ozone gas may not be good for us,
but this risk is greatly mitigated as OZONO devices infuses the Ozone
gas into the water (Aqueous Ozone). Due to its extremely short half-life, the Ozone gas will have broken down and returned into Oxygen by the time the water exits the drainage system. Ozone has been used in professional cleaning for decades as a powerful disinfectant and cleaning agent. Since the Covid-19 pandemic, Ozone has become a cleaning agent of choice, especially in high traffic locations such as Singapore’s Changi Airport (as of 2022).
