Air Cleaners
Indoor air pollutants are unwanted, sometimes harmful materials in the air. Usually the best way to address this risk is to control or eliminate the sources of pollutants, and to ventilate a home with clean outdoor air. The ventilation method may, however, be limited by weather conditions or undesirable levels of contaminants contained in outdoor air. If these measures are insufficient, an air cleaning device may be useful. The following publications will provide information on different types of air cleaning devices and how they work.

| Ozone Generators That Are Sold As Air Cleaners
For general audiences, this fact sheet provides 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. 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 proven to be both safe and effective to reduce pollutant concentrations, which include controlling pollutant sources and increasing outdoor air ventilation.
