The American Lung Association recently issued a health warning to American consumers regarding the use of ozone generators. They state that people using the devices may be jeopardizing their health and that the American Lung Association considers ozone devices a public health hazard. For more information the Internet site of the American Lung Association can be found at www.lungusa.org. You can also call the American Lung Association at 1-800-lung-usa and request a copy of their brochure entitled “A Guide to Residential Air Cleaning Devices.”

Health Canada has issued an advisory regarding ozone generators which states:

Ottawa — Health Canada is advising the public not to use air cleaners designed to intentionally generate ozone (ozone generators) in their homes. Health Canada is concerned with the adverse effects that may result from the deliberate exposure of the public to ozone from air cleaners that intentionally generate ozone gas. Ozone is an irritant that can cause coughs, chest discomfort, and irritation of the nose and throat. The direct and purposeful generation of ozone indoors should be avoided.

“Following a review of current information and in consultation with Health Canada and others, the Canadian Standards Association recently made the decision not to certify these products for household use and issued the new interim requirements for commercial units.”

“Health Canada advises all owners of ozone generators to stop using them in their homes. Health Canada is working with manufacturers and distributors of air cleaners designed to intentionally generate ozone to voluntarily recall any ozone generators (residential or commercial) sold to consumers for household use.

The Environmental Protection Agency (EPA) has issued a paper entitled “Ozone Generators that are sold as Air Cleaners: An Assessment of Effectiveness and Health Consequences.” This can be found at their Internet site http://www.epa.gov. In this 13 page paper they state:

Ozone generators that are sold as air cleaners intentionally produce the gas ozone. Often the vendors of ozone generators make statements and distribute material that lead the public to believe that these devices are always safe and effective in controlling indoor air pollution. For almost a century, health professionals have refuted these claims (Sawyer, et al 1913; Salls, 1927; Boeniger, 1995; American Lung Association, 1997; Al-Ahmady, 1997). The purpose of this document 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.

Some vendors suggest that these devices have been approved by the federal government for use in occupied spaces. To the contrary, NO agency has approved these devices for use in occupied spaces.
