Summary:

Ozone, the main component of air pollution, or smog is most often associated with outdoor air but it also infiltrates indoor environments like homes and offices and with people in industrialized countries spending as much of 80 percent to 90 percent of their time indoors, eliminating ozone is a health priority. University researchers studied the effects of three common houseplants on reducing ozone concentrations in a simulated indoor environment and found positive results.
