DESC: This dehumidifier is perfect for moisture control in cold areas with space constraints or crawl spaces. Its unique size of 1 ft. high x 1 ft. wide and low energy consumption make it an excellent choice for smaller areas. This unit is very quiet with a sound level similar to a quiet conversation, and can remove moisture down to 33°F thanks to Ebac's Hot Gas defrosting feature which automatically eliminates frost build up on evaporator coils, providing continuous, effective dehumidifier operation at low temperatures.
