Ozone generators and mold
Question submitted on 5/4/06

Do ozone generators kill mold?


U.S. EPA has a factsheet addressing this issue. It also includes a substantive bibliography and links to other resources:

Ozone Generators That Are Sold As Air Cleaners
The purpose of this fact sheet is to provide accurate information regarding the use of ozone-generating devices in indoor occupied spaces. This information is based on the most credible scientific evidence currently available. Whether in its pure form or mixed with other chemicals, ozone can be harmful to health. Some studies show that ozone concentrations produced by ozone generators can exceed health standards even when one follows manufacturer’s instructions. Available scientific evidence shows that, at concentrations that do not exceed public health standards, ozone is generally ineffective in controlling indoor air pollution. The public is advised to use proven methods of controlling indoor air pollution.
