Overview
With public concern about indoor air quality rising, many people are unknowingly making it worse by using air purifiers or other devices that intentionally inject ozone into the indoor spaces. Manufacturers and vendors of ozone generators often claim that these devices eliminate bacteria, mold, and chemical contaminants from the air, and that they help persons with asthma and allergies. This is not true or backed up by any scientific research. Independent studies by the Environmental Protection Agency (EPA) and others have shown that these devices do not effectively destroy microbes, remove odors, or reduce indoor pollutants enough to provide any health benefits. In fact relatively low amount of ozone can be harmful to health and worsen chronic respiratory diseases.
This 4-hour course provides guidance on ozone’s true capabilities, potential benefits and limitations in improving indoor air quality. This course attempts to address the common vendor claims and myths associated with use of ozone in indoor spaces.
This course is applicable to general public, HVAC engineers, facility engineers, architects, environmentalists, operations and maintenance personnel, as well as consultants and contractors who construct, build and manage facilities.
