NARA University Medical Study confirms Ozone inactivates SARS COV-2
Ozone kills air-borne viruses – read what the research says.
The greatest challenge the world is facing today is to win the battle against COVID-19. Alongside the vaccine, keeping indoor spaces sanitised and sterile, with clinically proven methods are the most important tools we can use to equip ourselves with in the fight against SARS-CoV-2.
Universities globally are researching the techniques used to kill coronavirus. The Nara University study demonstrates that the SARS-CoV coronavirus is killed by the application of ozone.
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.
Ozone machines sterilise surfaces and air at the touch of a button
The Nara University study highlights the powerful capabilities of ozone generating technology. The OZO Compact and OZO Sanitiser are well received in health care and nursery settings and most commercial environments where duty of care is paramount. Achieving sterilisation at the touch of a button is welcome and well received to face the challenges created by the COVID-19 pandemic.
