Many factors can contribute to your home’s overall indoor air quality, such as when the home was built, ventilation design, how well-sealed/insulated your home is, and more. The single most important factor, however, is your home’s air exchange rate, also known as its ability to change air. This all boils down simply to how often your home circulates new air inside.
With windows open, the average home experiences four to five changes per hour. This is decreased by more than 60%, down to only one to two changes per hour with windows and doors closed. This decreased airflow can expose you and your family to higher concentrations of VOCs (volatile organic compounds) from off-gassing of building materials, carpet, flooring, and even household chemicals. Other allergen triggers such as pollen, dust, and pet dander are trapped inside your home and can be a nightmare for family members who suffer from seasonal allergies and asthma.
Since it only makes sense to not waste energy by having the windows open, we often sacrifice our indoor air quality for efficient heating and cooling. However, whole home indoor air quality systems are available which are designed to drastically reduce indoor pollutants and increase the quality of the air we breathe indoors, all while still allowing energy to be cons
