In 1740 Schonbein discovered ozone, and in 1891 the molecular composition was modeled. Observation soon revealed that ozone reacted with and destroyed bacteria and other organisms. Nikola Tesla began one of the first ozone companies, in 1900. Ozone was widely used by many American doctors.

During the First World War, the application of ozone to war wounds served primarily as a disinfectant. In 1934, the dentist E.A. Fische and the surgeon Erwin Payr found that ozone saturated water was a great bactericide and began using it. This usage slowed temporarily because the ozone would quickly destroy the rubber tubing it flowed through. The arrival of Teflon and silicone tubing overcame this problem.

Today the largest commercial use of ozone is in the purification of water. Both the FDA and EPA certify ozone as destroying 99.9992% of all pathogenic germs, while simultaneously oxidizing 99.9992% of all water-borne pollutants.
