This portable air conditioner provides cooling where ordinary models can't--such as in a windowless office--because it doesn't require venting to the outdoors. The unit produces 7,000 BTU of cooling power and has an integrated exhaust fan that expels warm air away from you, enabling it to cool over a 225' sq. area. The flexible duct can be rotated 360º and twisted any which way to direct cooling breezes where they are most needed. Instead of a thermostat, the unit has two fan speeds, dehumidifies by collecting water in a removable tank, and traps dust from the surrounding air with a built-in washable filter. Though powerful, the air conditioner operates as quietly as a fan, and it maneuvers easily on four casters. The unit's 5' power cord comes with a GFCI plug for added safety. 23" H x 18" W x 10" D.
