If these quacks were actually producing ozone concentrations they claim to be producing - 119 micrograms per mL, which corresponds to over 60,000 ppm - the output of their device would be lethal in one breath. Fortunately, I think we can be quite sure it doesn't. But in any case, I'll be passing on the link to the FDA.
In the meantime, please stop offering potentially fatal medical advice on FR, and peddling snake-oil.
Bump for later reference...
