This swamp cooler offers three functions-blowing, humidifying, and cooling-to keep your home comfortable in hot weather. Designed with wheels and side handles, the portable unit can be easily moved to your outdoor patio without worrying about water in the tank spilling.With adjustable airflow up to 2100 CFM, it can effectively cool a room of about 750 sq. ft. You can manually adjust the vertical angle of the louvers for optimal comfort, and it also automatically oscillates horizontally from 0° to 72°, ensuring cool air reaches every corner of the room.To enhance cooling, it comes with 4 ice packs (to further lower water temperature) and 3-sided rigid high-density cooling pads (which increase evaporative surface area for more cool air). It also features easy operation: both the touch panel and remote control let you adjust fan speed, oscillation, sleep mode, and the 12-hour timer-so you won't need to wake up to turn it off after falling asleep.Plus, it has a water shortage protection function and a large 7-gallon tank. The tank can connect to a garden hose for non-stop cooling (no frequent refills needed), and it also supports top refilling-convenient for the elderly and pregnant people, who won't have to bend over. Color: white.
