Despite our home being the centerpiece of our lives; the quality of the air that we breathe is often overlooked. When the price of heat rose in the late 20th century, we began to take measure to conserve heat in our homes and make them more energy efficient. In doing this, we have sealed up homes, often to an extent that can become unhealthy.
The lack of adequate ventilation can lead to high levels of relative humidity and promote condensation on cold building materials (exterior walls, windows, toilet tanks, carpeting laid on poorly insulated flooring, etc).
This moisture promotes the growth of mold that can attribute to respiratory irritation. Furthermore, the lack of adequate ventilation can also contribute to the buildup of other pollutants such as: VOCs, formaldehyde, fragrances, cleaning agents, cosmetics, etc.
