I am interested in your home ventilation system to provide a healthy air exchange in our house.

Mary, thanks for asking. Aprilaire has a couple of choices when it comes to ventilation systems. One is an Energy Recovery Ventilator (ERV) which is better for larger homes and and in addition to adding fresh air, can reduce excess humidity levels.
The other is the Aprilaire Ventilation Control System, which is less complicated (and less expensive) than an ERV, but still provides fresh air into your home in a much more controlled way than passive ventilation that is often standard in most home construction practices; especially from years ago.
Ventilation Control System uses a sensor to "test" the outside temperature and humidity conditions so that it only allows fresh air into your home when the conditions are less severe from a temperature and humidity standpoint. The results are that you get fresh air in your house without letting in severely humid, hot or cold air. So you can maximize energy efficiency.
It's important to do your homework, Mary; which by your inquiry it appears that you are. Ultimately you'll need to talk to a indoor air quality specialist in your area to assess your home's specific needs before you make a decison. A good place to start is our Find A Dealer locator on our home page.
