Aqueous ozone for hand sanitation

Hi Jana -- this is a bit of a late response, but I just joined the group and am looking through recent posts. First off, I would like to applaud that company for providing some links to the scientific literature (see the FAQs page).  Those papers and other independent research papers I could find suggest that ozone in water is safe (ozone in air is another matter) and that it is effective at inactivating SARS-CoV-2.  However, one of these papers suggests hand sanitizers (70% alcohol tested) are even more effective at inactivating SARS-CoV-2 than ozone. 3Oe Scientific claims their process (including the spray system) kills 99.9%+ of the SARS-CoV-2 viruses in 7 seconds, but without publishing their research and/or having independent confirmation, that is in the realm of marketing speak and should be trusted accordingly. My takeaway is that it is an effective option for combating Covid transmission, but its not so clear that it is any better than a (much cheaper?) alcohol-based hand sanitizer station.  The ozone-cleaning technique is supposedly gentler on the skin and it is hands-free, so there are some benefits, but it also requires you to hold your hands in(?) the device for 7+ seconds, whereas the hand sanitizer can be applied as you walk away from the dispenser.  And if studies of hand-washing in bathrooms is any indicator, you cannot rely on a substantial portion of the general public to devote that kind of time to simple hygiene.
