● Not Just a Fan: This air cooler reduces temperature through water evaporation. It can be used as a fan or humidifier. It performs best in hot/dry climates where humidity levels are <50%, and ideal for use in the home, office, dormitory and so on.

● Easy to Operate: This air cooler is mechanical. You can easily choose between 3 wind speed settings (Low/Middle/High) for optimum comfort by turning the knob. Besides, you can put two ice-crystal boxes into the water tank in order to enhance cooling performance.
● Easy to Move and Storage: The compact and lightweight air cooler is easy to carry and store, and fits discreetly in most spaces. 4 caster wheels make it easy to move your unit from room to room.
● Swing Mode: Under the swing mode, the wind can be swung automatically on left and right and choose the wind-up and down by hand. The swing feature can distribute the air around the room and make the whole room cool.
