SmartAir Graph (image)
Caption
This graph shows that when a home heating and air conditioning system turns on and off based on temperature alone (Normal), the air quality in the home can result in the dirtiest air based on 2.5 particulate matter. Meanwhile leaving the heating and air conditioning on all the time (On) results in the cleanest air at the expense of using the most energy. The SmartAir plot shows that a system that turns on and off based on both temperature and air quality can result in a home with much cleaner air but without a much higher cost in energy.
