A dehumidifier is simply an air conditioner that has both hot and cold coils in the same box. A fan draws the room's air over the cold coil of the air conditioner to condense the moisture (which normally drips into a bucket). The dry air then passes through the hot coil to heat it back up to its original temperature. This is a good way to keep the inside of your home free of moisture. You can find dehumidifiers at any home store. Another option is a air exchange system. Air Exchange Systems are kind of like a dehumidifier but they do much more. Essentially they bring air from the outside (cold or hot) and replace it with air from the inside (cold or hot). In cases where the air is humid inside, it pulls the air out of the house and replaces it with air that has been dehumidified from the outside. So not only does it dehumidify the interior air but it replaces stale air with fresh air. There are many systems out there, although I specify The LifeBreath System by Nutech Brands Inc.

That's it for Part 1. I hope this helped in some way. In Part 2 I will talk about moisture from the outside and things that can be done, or not done, to work with straw bale design and construction. Thank You!
