The State of California has banned ozone generators wherever there are people nearby.
Once sold as a miracle device to cure Anemia, Hay Fever, Coughs, Catarrh, Asthma, Bronchitis, Insomnia, Nervous Debility and Tuberculosis, California’s Department of Air Resources says that marketers of indoor ozone generators are once again deceiving the public.
“There are thousands of peer-review studies showing ozone is dangerous,” states the American Lung Assn. of California. Anyone caught selling the devices after a two-year phase-in period  could be subject to fines starting at $1,000 a day. [story]
