Indoor Air Quality

Most people spend about 90 percent of their time indoors and are unaware that air pollution levels inside buildings may be higher than outdoor pollution levels; U.S. Environmental Protection Agency (EPA), studies of human exposure to air pollutants indicate that indoor levels of pollutants may be 2 to 5 times—and occasionally more than 100 times—higher than outdoor levels.
