A true workhorse, this BLACK+DECKER portable dehumidifier can extract up to 70 pints of water from the air in a 24 hour period. The extra large, 16.9 pint bucket means having to emtpy it less and there's also a continuous drain mode to avoid emptying altogether by adding a hose and finding an external receptacle. On castors, it moves easily from room to room and operates in a wide 54 degree range.
