How does ozone kill a virus? Typically, viruses are small and independent particles, built of crystals and macromolecules which multiply only within the host cell. The new coronavirus is considered an “enveloped virus”. Enveloped viruses are usually more responsive to physico-chemical challenges. In past studies, 99% of viruses have been destroyed or damaged after 30 seconds of exposure to ozone (O3). Ozone smashes viruses by diffusing over the protein coat into the nucleic acid core, arise in damage of the viral RNA. At higher concentrations, ozone (O3) destroys the external protein shell by oxidation.
When disinfecting large areas, ozone (O3) gas has been confirmed to kill the SARS coronavirus. Because the formation of the new 2019-nCoV coronavirus which is almost identical, is somewhat safe to believe that it’ll also work on the new coronavirus. Presently, there are more than 17 scientific studies which prove ozone gas is able to destroy the SARS coronavirus.
How Ozone Works
Because of the way that ozone turn back to oxygen over time, ozone can’t be delivered in tanks. Instead, ozone must be produced on site by an ozone generator.
Ozone generators produce ozone by adding energy to oxygen molecules (O2) which cause the oxygen atoms to split and temporarily rejoin with other O2 molecules, creating ozone (O3).
Ozone in Action
Once ozone is produced it reacts with a pollutant, often long chain carbon (organic) molecules and breaks it down into less complex (typically less harmful) molecules via a process called oxidation.
This process happens in nature by two ways:
Either Lightning (Corona Discharge) or Sun (UV light).
Ozone that has not reacted with other molecules will decompose into oxygen over time.
Sources of Oxygen
In light of ozone’s characteristics, it cannot be stored or transported, and must be made on site. Ozone can be produced from:
- Ambient Air – air that is available in the environment, whether it is placed indoors or outdoors.
- Dry Air – air that has moisture evacuated so the dew point is -70° F or lower
- Concentrated Oxygen – an oxygen supply, which is at least 90% pure, with moisture evacuated to a dew point of -40° F
Industrial ozone (O3) generators work very identical to ambient air units.
