Improve the comfort level of your home with Danby 70-Pint portable dehumidifier. This energy efficient unit operates quietly on 2 fan speeds (high/low) in rooms up to 4,500 square feet. It has a smart dehumidifying function that allows the unit to automatically control humidity by factoring in ambient room temperature. If the unit shuts off unexpectedly due to a power outage, it will automatically restart with the previous function settings when power is restored. The automatic de-icing system ensures the coils are always ice-free while the low temperature feature allows the system to continue to operate at temperatures as low as 41F. Maintenance is easy with the removable air filter and direct-drain system. Plus, Danby 70-Pint dehumidifier has four built-in caster wheels making it easy and convenient to move the unit from one room to another.
