Use of ozone generating devices to improve indoor air quality

Am Ind Hyg Assoc J. 1995 Jun;56(6):590-8. doi: 10.1080/15428119591016827.


Room ozonization has been in widespread use to "freshen" indoor air for more than 100 years. This use is sometimes promoted with the claim that ozone can oxidize airborne gases, and even particulates, to simple carbon dioxide and water vapor. Aside from whether ozone can improve indoor air quality, the potentially deleterious consequences to public health of overexposure to ozone are of concern. The literature on both allegations is reviewed. It indicates that ozone is not a practical and effective means of improving indoor air quality, especially in light of its potentially serious risk to health.
