Supply ventilation systems allow better control of the air that enters the house than exhaust ventilation systems do. By pressurizing the house, supply ventilation systems minimize outdoor pollutants in the living space and prevent back drafting of combustion gases from fireplaces and appliances.
The issue of good ventilation in a home is essential for the occupants of the building and for the building itself. Home ventilation systems has their advantages and disadvantages.
