The Ozone and SARS-CoV-2 experiment:
SARS-CoV-2 was cultivated and applied on a stainless steel plate in an air tight box installed in a safety cabinet. The Ozone concentration within the air tight box was controlled and maintained from 1.0ppm to 6.0ppm.
SARS-CoV-2 was inactivated with variable results in reference to the PPM level achieved.
- 90-99% at 1PPM
- 99.99% at 6PPM
The findings from the Nara University study confirm that a high concentration of Ozone is capable of a 4-log (99.99%) kill on the SARS-CoV-2 virus.

How does Ozone kill a virus?
Viruses are small independent particles, built of crystals and macromolecules that multiply only within the host cell. The new coronavirus is considered an “enveloped” virus and as such is more sensitive to physiochemical challenges. Ozone destroys viruses by diffusing through the protein coat into the nucleic acid core resulting in damage of the viral DNA. At higher concentrations, ozone destroys the exterior protein shell by oxidation.
Primary spread is through the air however research has shown that the virus can live on surfaces such as doorknobs or tables for several days. A study conducted at the Cleveland Clinic has shown the virus can live on glass for up to 5 days, wood up to 4 days and plastic and stainless steel for up to 3 days.
As a gas, it can penetrate all areas within a room, including crevices, fixtures, fabrics, and the under surfaces of furniture, much more efficiently than liquid sprays, aerosols, or ultraviolet light.
