With autumn on our doorsteps we will be soon closing the windows to keep us from the cold air and proper ventilation. On average, people in the New England States spend much of their fall and winter time indoors. This means that the atmosphere inside our homes makes an impact on our health. Research has shown that indoor air pollution can have more damaging effects on health than pollution in the air outside.  
Our health benefits from the removal or reduction of mold producing moiusture, allergens, VOC’s and other gasses found in homes such as Radon.
The EPA states: “Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house. Opening windows and doors, operating window or attic fans, when the weather permits, or running a window air conditioner with the vent control open increases the outdoor ventilation rate. Local bathroom or kitchen fans that exhaust outdoors remove contaminants directly from the room where the fan is located and also increase the outdoor air ventilation rate. The introduction of outdoor air is one important factor in promoting good air quality. Most residential forced air-heating systems and air-conditioning systems do not bring outdoor air into the house mechanically, and infiltration and natural ventilation are relied upon to bring outdoor air into the home.”

As Fresh As All Outdoors

Kitchen and bathroom vents should lead directly outside and should never be vented into the attic, where moisture can cause serious problems and pose potential health problems. • Consider adding controlled ventilation after you air seal. It may be necessary to provide fresh air to avoid buildup of stale air and indoor air pollutants.
