With the emphasis on energy conservation and efficiency, new home construction can create a problem of indoor air pollution. Vapour barriers, thermal windows, weather-stripping and caulk have reduced or stopped fresh air from infiltrating and replacing stale air. Entering and exiting the house through doors isn't always enough air changes. Cooking, aerosol sprays, cleaning agents, paints, and in some cases excess humidity if the house is sealed too tightly can create an undesirable environment. Keeping windows or doors open does not conserve energy. A device known as an air-to-air exchanger is used to recover heating or cooling and improve air quality.

Heat-recovery air exchangers capture heat from stale moist air and transfer that heat to the fresh air intake so that your heating system will not have to work so hard to condition that air.
