Factors Affecting Indoor Air Quality

by Wendy Brandt Martinenas

On average people spend 90% of their time indoors so it’s important to know that indoor air can be more polluted than outdoor air. Primary causes are sources that release gases or particles into the air, inadequate ventilation and high temperature & humidity levels.

There are both indoor and outdoor sources that lead to poor indoor air quality. Some of the culprits from the indoors are:  oil, gas, tobacco, asbestos containing insulation, wet or damp carpet, household cleaning products, and central heating & cooling systems.  And from the outdoors:  radon, pesticides and car exhaust fumes.     Moisture exacerbates the problem because when bacteria, mold & pollen are exposed to water for prolonged periods of time they breed.  Water can accumulate in ducts, humidifiers and drain pans, or where water has collected on ceiling tiles, carpeting, or insulation.

For good indoor air quality you should have adequate transfer of air from the inside to out and your home should be kept dry.
