As America moves away from the use of natural gas and propane for home heating and cooking, the danger of carbon monoxide will disappear, but there are many other pollutants that are getting homeowners’ and builders’ attention.
It’s rare that a home buyer doesn’t order a radon measurement and demand that the level of radon gas be reduced through mitigation to below the EPA action level.
Also of concern are “volatile organic compounds,” which come from carpeting, particle board and other construction materials and furnishings.
Exhausting these gases and bringing fresh air into a home is just as important as filtering the air that is in your home. A new appliance that you’ll hear more and more about and begin seeing alongside furnaces and water heaters in your utility room is the Energy Recovery Ventilator (ERV) or the Conditioning Energy Recovery Ventilator (CERV), which monitors air quality and responds accordingly. Google it to learn more about it.
