Description:

The report gives information on home/office ozone generators. It discusses their current uses as amelioratives for environmental tobacco smoke, biocontaminants, volatile organic compounds, and odors and details the advantages and disadvantages of each. Ozone appears to work well against household odors and environmental tobacco smoke, but caution needs to be exercised in its use because of the production of byproducts such as formaldehyde. Ozone has biocidal effects, but its use in household settings is limited by the high concentrations needed for complete kills. Ozone has decremental effects on lung function in humans that persist for 24-28 hours. In the experiments conducted at the indoor test house, each of the three ozone generators studied produced concentrations in excess of the Occupational Safety and Health Administration limit for workplace exposures. In addition when interior doors were left open, adjoining rooms were also subjected to such exposures. Total ozone decay times for all the concentrations studied did not exceed 12 minutes.
