Gerkin recommends utilizing air exchange ventilators in your home. With the increase of energy efficient (tight) homes being built and older homes being upgraded, it is even more important to properly ventilate the indoor air.
Vapor barriers, home super insulation packages, thermal windows, weatherstripping, and caulk have reduced or stopped fresh air from infiltrating and replacing stale air. Entering and exiting the house through doors doesn’t provide enough air exchange. Proper ventilation is needed in all four seasons of the year.
Carbon dioxide (CO2), dust mites, mold, pet dander, dust, smoke, Volatile Organic Chemicals (VOCs), and other airborne pollutants are forced to stay inside the home if the house is sealed too tightly and can create an undesirable environment. Excess humidity increases the potential growth of mold, mildew, and can cause deterioration to your home and structural damage to wood framing.
Indoor air contains up to 100 times more pollutants than outdoor air. People now spend up to 90% of their time indoors. If your house is stuffy, odors linger or humidity is high in fall and winter, it is likely that your house does not have adequate ventilation. If someone in your house has headaches, chronic fatigue, poor concentration, respiratory conditions, such as chronic colds and flu viruses, aggravated allergies, asthma, or bronchitis, getting the proper amount of ventilation is even more important.
