The California Air Resources Board (CA ARB) finalized the regulation order for limiting ozone emissions from indoor air cleaning devices. Indoor air cleaning devices for use or intended for use in occupied spaces can’t be sold, provided, offered for sale, or introduced into commerce unless the device has been certified by ARB to produce an ozone emission concentration that does not exceed 0.05 part per million.
The International Ozone Association (IOA) has stated at CA ARB meetings that ozone may be effective for reducing the odors that are released by fire damage, cooking, animal and smoke odors, mold and other organisms from air and surfaces in a building if applied and controlled at sufficiently high concentrations.
These levels are generally higher than what is considered to be safe for prolonged exposure in most plants, animals, and people. IOA, therefore, supports regulations that limit the use of air purifiers that emit ozone in occupied spaces.
Indoor air pollution is one of the top five environmental hazards to human health, according to the EPA. You can read more about EPA’s guidelines about using ozone. According to California’s Air Resources Board, Americans spend 90% of their time indoors. California spends around $45 billion a year on premature deaths, lost employee productivity, and medical treatment due to indoor air pollution.
Over the next 15 years, asthma is expected to increase by around 22 percent. Approximately 532,000 (39%) of 1.36 million doctor-diagnosed cases in children under six are anticipated to be prevented if indoor pollutants and allergens are eliminated from housing.
