In a nutshell, the reason why we can and do sell ozone generators in California (from our website, not Amazon, they block all ozone products from sale in California) is that our ozone generators are not air purifiers, they're commercial shock treatment ozone generators and are marketed and labeled as such. First, here is the law:
Standards for Indoor Air Cleaning Devices. Except as provided in Section 94803 (Exclusions and Exemptions), title 17, California Code of Regulations, no person shall manufacture for use in California 24 months after the effective date of this regulation, or sell, supply, offer for sale, or introduce into 4 commerce, any indoor air cleaning device for use or intended for use in occupied spaces unless the device is certified by ARB to produce an ozone emission concentration not exceeding 0.050 ppm, as specified in Section 94804; is labeled as required in Section 94806; meets all requirements of this article; and continues to meet all requirements of this article, including the ozone emissions limit as determined by the test procedure in Section 94805. § 94803.
Exclusions and Exemptions. (a) Industrial use: The provisions of this article do not apply to indoor air cleaning devices manufactured, advertised, marketed, labeled, and used solely for industrial use as defined in Section 94801(a)(15) above, provided that they are marketed solely through industrial supply outlets or businesses and prominently labeled as “Solely for industrial use. Potential health hazard: emits ozone.”
“Industrial use” or “industrial application” means the use of ozone in the following manner:
(A) purification of water in an industrial plant, water treatment facility, municipal water facility, or similar facility, and swimming pools and spas
(B) the destruction of microbes on produce in an agricultural processing plant, refrigerated transport truck, or related facility
(C) chemical oxidation and disinfection in the electronics, pharmaceutical, biotechnology and chemical industries
(D) bleaching and other processing purposes in the pulp and paper industry
(E) odor control from industrial stack gases or wastewater treatment facilities
(F) odor and smoke control in the hotel industry, provided no people are physically present
(G) mold remediation, provided no people are physically present
(H) fire and smoke damage remediation, provided no people are physically present
(I) odor control in the motor vehicle reconditioning and detailing industry provided no people are physically present.
Ozone shock treatments are approved and used in various industries to sanitize, clean, and remediate odors, smoke damage, kill mold, and remove the stench of decaying organic material. The smell of rotting flesh creates a funk that sticks to all surfaces, and the only way to remove it is with an ozone shock treatment. We only sell industrial strength ozone generators that emit ultra high levels of ozone, 10, 20, 40 grams of ozone per hour! That is so much ozone it can in no way can it be reasonably used as an air purifier in an unoccupied room! Ozone air purifiers typically utilize MICA ozone plate technology. This older technology uses wire mesh to produce low levels of ozone, usually 300-400 milligrams per hour per ozone plate. That amount of ozone cannot get rid of odors, all it can do is freshen the air. However, when it gets cold, or if the room is too small, the ozone can build up to 1 ppm or higher and cause health issues to asthmatics or folks with reduced lung function. Every year people using ozone air purifiers (or mistaking specific types of ozone generators for air purifiers which is never an issue with our science project looking machines) are rushed off to the hospital because they have difficulty breathing. In almost all cases, the ozone machine is turned on at night, and the problems happen while people are sleeping since ozone is "self-regulating". By self-regulating I mean that ozone makes you cough if you breath too much and if you don't cough, no worries, you didn't breath too
The state of California passed this law to protect their citizens from using ozone generators as air purifiers because it is true that a certain percentage of the population is not bright enough to read or follow instructions or log onto the Internet to figure out the correct way to use a device that has a fan and a filter and looks like an air purifier and produces a nice fresh scent (ozone). Every Forever Ozone machine comes with a sticker that states that 1) This is an industrial ozone shock treatment machine and 2) It is only to be used in unoccupied areas as it emits high levels of ozone. Nowhere on our website or out manual do we state that it is okay to breathe ozone or be in the area when the ozone shock treatment is being performed. The homeowner, in this case, is acting as a contractor, per our terms of service, to perform an industrial process on their own and agree to adhere to our safety suggestions and use the device only as intended, in unoccupied rooms.

Thanks for your help passing the word on Forever Ozone shock treatment ozone generators to California businesses and homeowners!
