Data released in the AirAdvice State of Our Indoor Air Report 2007, a landmark report developed by AirAdvice Inc. based on the analysis of 49,130 indoor air quality tests conducted in homes across North America, shows that people in 9 out of 10 American homes are breathing unhealthy indoor air.

Overall, 96.7% of all homes tested had at least one of six indoor air quality (IAQ) problems analyzed in the AirAdvice study -- particle allergens, chemical pollutants, carbon dioxide, temperature, humidity, and carbon monoxide.

Most homes had multiple indoor air problems. Eighty-three percent of all homes tested exhibited two or more of the six problem types; nearly half (49.8%) had three or more problems; 18.9% had four or more.

The most rampant indoor air quality problem in North American homes is particle allergens (e.g., dust, dander, pollen, spores, bacteria, and other airborne pollutants). Over 91% of homes tested showed elevated particle allergen levels. Occupants of homes with elevated particle allergen levels are at risk for adverse symptoms and diseases including asthma and allergies. According to the American Lung Association, in 2004 an estimated 30.2 million Americans -- more than 1 in every 10 people -- had been diagnosed with asthma in their lifetime.

Chemical pollutant problems were the second-most frequent type of problem found. Elevated chemical pollutant levels were found in 7 out of 10 homes (70%). Some chemical pollutants are known carcinogens (cancer-causing).

Carbon dioxide, temperature, and humidity levels were outside recommended ranges in many homes -- 45%, 30%, and 49%, respectively. Carbon monoxide, a clear, odorless, and potentially deadly gas, was found at elevated levels in 2% of homes.
