How is your Indoor Air Quality?

Here are some interesting facts from the American Lung Association:

  • 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.
