This portable air conditioner earned The Best rating from the Hammacher Schlemmer Institute because it cooled most effectively and offered more convenient features. The Best Portable Air Conditioner lowered the ambient temperature by 7.33º F in two hours, while competing models could only muster a 2.33º F decrease. Unlike lesser portable air conditioners with limited controls, The Best model has an energy-saving mode that automatically chooses the fan speed based on the current ambient temperature and the unit's set temperature. The unit can be programmed to turn on and off automatically at pre-set times, and its louvers can be set to oscillate for more even air distribution. The 14,000 BTU unit cools a room up to 400' sq. and also functions as a 12,000 BTU heater, a fan, or a dehumidifier. The Best model rolls on four casters, its exhaust system rests between a sill and an open window, and it has a washable air filter. Includes remote control. 32 3/4" H x 19" W x 17 1/2" D. (83 lbs.)
