Because most modern homes are sealed, the air is laden with moisture and pollutants created from the daily activities of its inhabitants. The installation of an air exchanger inside the house will remove stale and polluted air from the house to the outside and replace it by an equivalence of fresh air. Generally, an air exchanger system installed properly will renew the air of all the important parts of the house.
Through a ductwork system installed in the walls; those ducts ending with fresh air distribution grilles and stale air exhaust grilles. Fresh air distribution grilles are located in each room of the house needing fresh air (which are, among others, bedrooms, kitchen and living room). The stale air to outside grilles are generally located at the highest level of the house, where the excess humidity and pollutants build-up.
The fresh air distribution and stale air exhaust ducts are connected to the air exchanger. Two other ducts are also connected to the unit: one for gathering fresh air from outside and the other one to exhaust the stale air to the outside. The air exchanger manages the ventilation for the whole house.
