Ventilation is the process of "changing" or replacing air in any space to provide high indoor air quality. In our homes and businesses some of the benefits of good ventilation are removing unpleasant smells and excessive moisture, to keep interior building air circulating, introduce outside air, and to prevent stagnation of the interior air.
