Is Your Indoor Air More Polluted Than Your Outdoor Air?

For most of us summer means closed windows and doors and conditioned air, The Environmental Protection Agency (EPA) says, "Indoor air pollutants are unwanted, sometimes harmful materials in the air. Indoor air pollution is among the top five environmental health risks. Usually the best way to address this risk is to control or eliminate the sources of pollutants, and to ventilate a home with clean outdoor air. The ventilation method may, however, be limited by weather conditions or undesirable levels of contaminants contained in outdoor air. If these measures are insufficient, an air cleaning device may be useful.
