CONTRIBUTION TO INDOOR OZONE LEVELS OF AN OZONE GENERATOR
Steiber*, R S. CONTRIBUTION TO INDOOR OZONE LEVELS OF AN OZONE GENERATOR. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-93/177 (NTIS 93-234557), 1993.
This report gives results of a study of a commonly used commercially available ozone generator, undertaken to determine its impact on indoor ozone levels. xperiment were conducted in a typical mechanically ventilated office and in a test house. he generated ozone and the in-room ozone concentrations were measured. he results showed that, when the unit was operated at the manufacturer's recommended setting, it generated little if any ozone. he indoor concentrations in this case were not significantly above natural background. hen operated at the maximum setting, the generator produced large amounts of ozone - over 100 ppb in well ventilated spaces, and nearly 1 ppm in poorly ventilated spaces. hen the ozone generator was turned off, ozone levels quickly returned to background. o measurements were made to determine the effect of the device on other aspects of indoor air quality such as the elimination of volatile organic compounds.
