Indoor Air Quality (IAQ)

Indoor Air Quality (IAQ) refers to the condition of air inside a house or building. This fact sheet provides general information about IAQ problems in the home and ways to correct them.

Many things can affect indoor air quality including:

Temperature – how hot or cold it is.
Humidity – the amount of water vapor in the air.
Indoor Pollutants – gases or particles from sources inside the home, such as cigarette smoke, household products (paints, cleaners) or building materials (pressed wood products, carpeting).
Outdoor Pollutants – contaminants that make their way into the home from outside, such as car and boiler exhaust, fires, or chemical releases.
Ventilation – odors and pollutants can build up indoors when there is not enough fresh air getting into the home.
Building maintenance – poor home maintenance can lead to cracks and leaks, which can cause pest infestations, mold growth and building damage.
