Japan researchers say ozone effective in neutralising coronavirus
TOKYO (Reuters) - Japanese researchers said on Wednesday that low concentrations of ozone can neutralise 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. (This time frame would be greatly reduced with higher levels of medical grade ozone used in our larger machines. For more information please contact us.)
