Facts About Indoor Air Pollution

  • Indoor air quality is one of the top five of the EPA’s environmental risks to public health.
  • Common indoor air pollutants include pollen, mold, dust mites, carbon monoxide, excessive carbon dioxide, radon, and other chemical fumes.
  • Indoor pollution is typically two to five times worse than the air outdoors. Sometimes up to 100 times worse.
  • Secondhand smoke from tobacco is a major indoor air pollutant. It contains about 4,000 chemicals, including 200 known poisons.
  • Secondhand smoke causes over 150,000 respiratory problems in infants and 38,000 deaths annually.
  • 10% of Americans have never changed the filter on their heating and air conditioning unit.
  • 75% of Americans live with someone who suffers from asthma, allergies, or other respiratory illnesses.
  • Poor indoor air quality can cause or contribute to asthma, headaches, dry eyes, nasal congestion, nausea and fatigue.
  • One out of 15 American homes has a dangerously high radon level. Radon naturally emits from the earth and enters the home through cracks in the foundation floor and walls, drains, and other openings. Indoor radon exposure is estimated to be the second leading cause of lung cancer.
  • Only 27% of Americans have carbon monoxide detectors at home. Carbon monoxide is a gas that can stop coordination, worsen heart conditions, and at very high levels, can cause death.
  • Asthma accounts for 14 million missed school days annually. (Centers for Disease Control and Prevention)
  • Health effects from indoor air pollutants may be experienced soon after or, possible, years later.(Environment Protection Agency)
  • Heating and cooling systems are the largest single consumers of energy in buildings. (Energy Star – EPA / DOE)
  • A dirty evaporator coil or condenser coil will reduce cooling capacity and degrade equipment energy efficiency. (U.S. Department of Energy)
