Air Exchanger Ventilation:

To prevent the "Sick House Syndrome" we have installed dual flow passive/active air exchangers in both bedrooms. These act as passive air vents when in the 'Off' position, allowing a small amount of air to flow in and out of the house. In the 'On' position they use a small fan to both push and pull air from the inside and outside of the house. The air runs through a filter system as well and these are great in keeping dust and pollen out of the air as well! The first picture is the mounting plate and the second is the actual unit itself. There will also be external vent covers on the outside of the house, which we custom ordered (I will post a pic when they arrive and are installed). We also have a system of passive vents throughout the house to allow for air pressure differences, 'sick house' prevention, humidity control, and fresh air for the wood stove. This is shown in the bottom picture.
