Indoor Air Quality

American adults spend about 90% of their time indoors, and thanks to our more tightly insulated/sealed homes and workplaces, the concentration of pollutants indoors may be even higher than outdoors.

Major indoor pollutants include environmental tobacco smoke (secondhand smoke); radon; combustion products stemming from sources such as pet dander, pollen, molds, and dust mites; volatile organic compounds present in paints, cleaners, pesticides, copiers, printers, glues, and adhesives; lead dust from old, lead-based paints; and asbestos.

Here are five easy steps you can take to reduce pollution at home:
Vacuum and clean regularly. Wipe your feet on a doormat. Better yet, take your shoes off when you enter your home. Avoid smoke from wood stoves, fireplaces, and cigarettes. Use less toxic products for managing pest problems in your home and garden. Use fans or open windows to reduce moisture in bathrooms and kitchens and reduce build-up of indoor pollutants.
