Ozone is a powerful oxidizing agent which produces a broad spectrum biocide that destroys all bacteria and viruses when dissolved in water. At the proper concentration, ozone can com-pletely inactivate most enveloped viruses such as SARS CoV-2. Ozone gas has a high oxidation potential which is 1.5 times greater than chloride when used as an antimicrobial agent against bacteria, viruses, fungi and protozoa.
