According to this recent article by Reuters, Japanese researchers have claimed that low concentrations of ozone can neutralize coronavirus particles, potentially providing a way for hospitals to disinfect examination rooms and waiting areas. 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 experiment used an ozone generator in a sealed chamber with a sample of coronavirus. The potency of the virus declined by more than 90% when subjected to low level ozone for 10 hours. “Transmission of the novel coronavirus may be reduced by continuous, low-concentration ozone treatment, even in environments where people are present, using this kind of system,” said lead researcher Takayuki Murata.

Additionally, a recent study at the Georgia Institute of Technology showed that ozone may be effective in disinfecting gowns, goggles and other medical protective equipment.
