Input:
A little pricy but good product.  The sound is slightly quieter than a standard box fan that I was previously using in the window trying to accomplish the same thing.  The perk is it has low, med, and high in both intake and exhaust.  Intake works great pulling air into a single room.  Exhaust is a little slower in pulling heat out and cool air into the house with other windows open but overall effective.
