a 22ft x 24ft x 10ft garage, we place the items directly in the generator's air flow and run it for 30 minutes.
Thats 1mg per cubic foot I think.
This is the chap I met with he has a page on it:
https://ozofreshplugin.co.uk/corona-information/The following is true to the best of our knowledge in relation to the effectiveness of ozone and how this applies to our products.
Ozone based products are known to be effective in controlling virus (such as swine flu) and this means it will likely be effective against other strains.
The amount and method of use must be appropriate for effective application.
We cannot state (for the reasons above) that our or any ozone product will be totally effective.
Some ozone products, such as our ProCleanz environmentally friendly surface cleaner have tested to the EN1276 standard which means they are effective against the flu virus H1N1, E-coli, Salmonella and have a 99.9% bacterial kill rate.
We understand several apparently legitimate sources in China and Thailand are recommending the use of ozone-generating devices such as ours to protect against the coronavirus.
Ozone products must not be relied upon to eradicate Corona Virus, however, they are known, when used correctly, to be effective against other similar pathogens.
But nothing on dose.
