Air ducts pick up lots of debris that contribute to poor indoor air quality. Even worse, they recirculate dirty air, making the problem worse. Here are a few examples of how this happens.
Excess moisture from several sources accumulates in homes with poor ventilation further aggravated by dirty air ducts. This can quickly lead to indoor air contamination. Here are few examples of how moisture can build up:
• Insufficient ventilation in bathrooms and/or kitchens
• Air conditioners that have not had at least yearly cleaning and maintenance
• Dirty humidifiers and filters
Mold can easily sprout inside these environments, particularly in high humidity regions.
Smoke and Particulates
Smoke and the particulates it emits are another source of indoor air contamination. This comes from fireplaces, wood stoves, and dirty furnaces. Gas space heaters in rooms with poor ventilation are another sources. Even candles can contribute to polluted indoor air. Tobacco products are well-documented sources for chemical contaminants as well.
Volatile Organic Compounds (VOCs)
Some cleaning agents, paints, adhesives, graphics and craft materials and other products emit harmful VOC chemicals that can easily become vapors or gas. If they are used or stored in the home, they can release air pollutants. Some of these products are in tobacco products as well.
In certain areas the ground beneath the home emits natural radon gas another source for indoor air pollution.
