What causes indoor air pollution?

Many everyday household items may contribute to poor indoor air quality. Compounds found in carpeting, furniture, upholstery and drapery fabric constantly emit gases or fumes. Other sources of pollutants are cleaning agents, paint and personal care products.

Though they are often more efficient, modern homes do not breathe (ventilate) the way older homes have. Tight-sealing weather stripping and storm doors keep indoor air in and outdoor air out. This provides higher energy savings, but the limited exchange of outdoor and indoor air can mean a buildup of contaminants inside your home. In these circumstances, a whole home ventilation system is recommended. Ventilation systems exchange stale indoor air for cleaner outdoor air, without sacrificing energy savings.
