ABSTRACT:
An apparatus is provided for removing airborne moisture from a designated area. In one embodiment, the apparatus includes a bucket, a liquid absorption medium (such as ground corn cobs) placed in the bottom of the bucket to form a media bed, a tray placed over the absorption media bed, and a moisture absorption medium (such as calcium chloride) placed in the bucket over the tray. A method is also provided for absorbing moisture from a humid environment using the apparatus. When the apparatus is exposed to humid conditions, the CaCl2will absorb moisture and become hardened. As the CaCl2media hardens, it will expand. However, its lateral expansion is restricted by a side wall of the tray. Over further time, the CaCl2will begin to dissolve into a brine. The brine will gravitationally seep through the through-openings in the tray and be captured by the corn cob medium.
