Ozone Generators That Are Sold As Air Cleaners

Ozone generators are sometimes marketed as air cleaners, but scientific research has shown that ozone can pose health risks when present at elevated levels. Ozone is a highly reactive form of oxygen that can irritate the lungs and worsen respiratory conditions such as asthma. Evidence indicates that ozone concentrations considered safe for human exposure are generally ineffective at removing indoor air pollutants, while higher concentrations needed for disinfection may exceed health safety limits. Because ozone levels indoors are influenced by many factors—such as room size, ventilation, and proximity to the device—controlling exposure can be difficult. Experts recommend focusing on proven methods to improve indoor air quality, including source control, proper ventilation, and effective air filtration systems.

, which explains that using ozone generators in occupied spaces can create health concerns and should only be done in controlled conditions with proper ventilation.
