The generated ozone gas is generated in the test tank space.
It has been demonstrated that it has an inactivating effect on the new coronavirus.
This result was obtained by a research commissioned to Nara Medical University.
This experiment:
A test piece with the new coronavirus attached is placed in a 6.7 L enclosed space.
Ozone generated from the ozonizer was irradiated with a fan for a certain period of time.
The test was carried out three times in an environment with a humidity of 50.0 to 59.7% and a temperature of 19.6 to 21.8 ° C.
Confirmed inactivating effect:
The virus was recovered from the test piece after the action time, and the virus infectivity titer, which is the number of particles of the virus having cell infectivity, was measured by the plaque method.
In “Ozone permissible concentration of Japan Society for Occupational Health, 0.1ppm”, “Inactivation effect of 99.9% or more after 120 minutes” was confirmed.
