Homes without adequate ventilation can have lingering odours and high humidity levels. ENERGY STAR® certified ventilation or exhaust fans including bathroom/utility room fans and range hoods, can provide the necessary ventilation to minimize or eliminate these problems resulting in a healthy indoor environment.
Ventilation fans have an electric motor that powers a fan. Moist air is drawn up through the fan into ductwork that exhausts to the outside.
