Carbon dioxide–or CO2–is a natural byproduct that occurs when we exhale. Reduction in CO2 level through proper ventilation has been associated with increased mental performance of occupants in numerous studies cited by the Environmental Protection Agency (EPA).
A properly installed and operating BROAN Fresh Air Systems can remove and dilute CO2 in the home and replace it with fresh air in a very energy efficient manner. BROAN air exchangers with Heat Recovery or Energy Recovery are designed to recover heating or cooling energy from outgoing air and transfer it to the incoming air. This provides your home clean, fresh air for pennies a day.
