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 include cleaning agents, paint and personal care products.

Though they are typically more efficient, newer 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 poor indoor air for fresh outdoor air, without sacrificing energy savings.
