Ventilation / Energy Recovery Ventilator
Trade stale indoor air for fresh air all year round. Energy
efficient windows and doors, thicker insulation and air tight
vapor barriers have made homes more efficient, saving both
energy and money. While this has made many homes more
efficient, it has also made it nearly impossible for these
homes to “breathe”, to expel the stale polluted indoor air and
exchange it for cleaner, fresher outdoor air.

“If too little outdoor air enters a home, pollutants can
accumulate to levels that can pose health and comfort
problems. Unless they are built with special mechanical
means of ventilation, homes that are designed and
constructed to minimize the amount of outdoor air that can ’
leak’ into and out of the home may have higher pollutant levels
than other homes. However, because some weather
conditions can drastically reduce the amount of outdoor air that
enters a home, pollutants can build up even in homes that are
normally considered ’leaky.’”
