Low Level Ambient Ozone Effectively Neutralizes Coronavirus

It is no surprise that ozone will neutralize coronavirus. Ozone is well known to be a powerful disinfectant. It is especially effective with small pathogens such as viruses and bacteria. Some of the more recent studies have demonstrated that coronavirus can thrive in the air in the form of aerosols breathed from people. Recent research has demonstrated that low levels of ozone gas effectively neutralizes coronavirus.

Ozone is a simple high-energy molecule of three oxygen atoms and will irritate sensitive tissue such as our lungs when ozone concentrations exceed 0.1 parts per million. The good news is that coronavirus is much more sensitive to ozone than our lungs are. “Scientists at Fujita Health University told a news conference they had proven that ozone gas in concentrations of 0.05 to 0.1 parts per million (ppm), levels considered harmless to humans, could kill the virus.”


The important details are the ozone level and the contact time. Coronavirus exposed to ozone concentrations of 0.1 ppm for 10 hours reduced the potency of the virus 90%. Ozone is not a magic bullet, but it is a valuable tool in our arsenal for fighting the virus. It is a safe, comfortable, and effective tool that can provide secondary benefits. The ultraviolet rays of the sun and lightning naturally produce low levels of cleansing ozone. Well-controlled equipment is already available to bring some of the fresh outdoors into our living and working spaces to stand side by side with others in the battle against viruses.

Oxidation Technologies has worked for years to produce safe and effective ozone generating equipment. We specialize in equipment controls to precisely maintain specified ozone levels for commercial applications. We have the equipment and expertise to maintain safe levels of ambient ozone that will greatly reduce the ability of coronavirus to thrive. We would be happy to assist in your efforts to get employees back into the workplace.

Ozone: A Potential Oxidant for COVID-19 Virus (SARS-CoV-2)

New white paper available from the IOA on the use of ozone to inactive the COVID-19 (SARS-CoV-2) virus. Abstract and summary below, full paper can be found HERE:



Currently, no medicine has demonstrated efficacy in treating the ongoing pandemic COVID-19 caused by SARS-CoV-2 virus. Being a potent oxidant, ozone is lethal against most bacteria and viruses found in water, or on surfaces and aerosols. Ozone has also been successfully used to treat several viral diseases such as Ebola and HIV Hepatitis B and C. Using molecular modeling, this study evaluated the reactivity of ozone toward representative key molecules in the structure of SARS-CoV-2. The results show that ozone is able to attack the proteins and lipids of the virus’s spikes and envelope, particularly the amino acids tryptophan, methionine and cysteine, and the fatty acids, arachidonic acid, linoleic acid, and oleic acid. Ozone also attacks the N-glycopeptides of the spike protein subunits 1 and 2, though at lower reactivity. Disruption of the structure of SARS-CoV-2 could inactivate the virus, suggesting that ozone could be an effective oxidant against COVID-19 virus. If incorrectly applied, ozone is toxic and contact with the respiratory tract must be avoided.


Ozone has been used successfully to inactivate pathogens and viruses in many applications and has a long history of success. Based on this the assumption is made that ozone will also inactivate the SARS-CoV-2 virus. This study uses representative viruses, and molecular modeling to provide that ozone could be an effective oxidant against SARS-CoV-2. Ozone was able to attach the proteins and lipids of the virus destroying the integrity of the virus rendering it unable to cause further infection or reproduction.
