Fourteen percent of homes may be at risk. Two percent (2%) of California households own an air cleaner that intentionally emits ozone (ozone generator), while eight percent (8%) own an air cleaner that may emit ozone as a by-product. An estimated 828,000 Californians (about 282,000 households) may be exposed to potentially harmful levels of ozone from ozone generators. Get the facts & get involved! Not all air-cleaning devices are appropriate for home use — some can be harmful to human health. The ARB recommends that ozone generators, air cleaners that intentionally produce ozone, not be used in the home. Ozone is a gas that can cause health problems, including respiratory tract irritation and breathing difficulty (Ozone and Health).
