In the past several decades, indoor air quality problems such as mold and its subsequent health issues have received increased awareness and attention from the public and the country as a whole. There are many types of molds and each type has the potential to cause unique health problems. In homes, mold spores are always in the air. In commercial buildings, there is always a continual flow of air circulation from bottom to top through the duct and venting system. So when moisture and humidity are introduced for a sufficient amount of time and inappropriate levels, air borne spores will start growing, reproducing, spreading, and damaging many household items and or the structure itself.
