ABSTRACT
Indoor air purifiers are advertised as safe household products for health-conscious individuals, especially for those suffering from allergies and asthma. However, certain air purifiers produce ozone ([O.sub.3]) during operation, either intentionally or as a byproduct of air ionization. This is a serious concern, because [O.sub.3] is a criteria air pollutant regulated by health-related federal and state standards. Several types of air purifiers were tested for their ability to produce ozone in various indoor environments at 40-50% relative humidity, including office rooms, bathrooms, bedrooms, and cars. [O.sub.3] levels generated by personal wearable air ...
