Does ozone kill viruses

Yes.

Ozone, also known as superoxide, is an allotrope of oxygen. At room temperature, it is a pale blue gas with a distinctive odor. At normal temperature and pressure, the stability is poor, can be decomposed into oxygen. Ozone has a grassy taste, inhaled a small amount of good for human health, inhaled in excess of certain harm to human health. Non-combustible, pure stuff. Oxygen can be changed into ozone by electric shock. Ozone is a strong oxidant, its REDOX potential in water is 2 eV, second only to fluorine, and its oxidation capacity is higher than that of chlorine and chlorine dioxide. It can destroy the cell wall of decomposing bacteria, quickly diffusing into cells, oxidizing and decomposing glucose oxidase, which is necessary for the internal oxidation of glucose in bacteria and can also directly interact with bacteria and viruses. The process of bacterial metabolism and reproduction is destroyed.

Usually, you can use industrial ozone generator.
