This cooling fan is more gentle than an air conditioner, and efficiently cools your body with a near-natural wind that is more cool than a fan. Utilizes vaporization heat and disperses cold air by applying wind to the wet filter. Large capacity tank reduces the hassle of water supply. The included cooling pack can be inserted into the tank with water, so you can feel even cooler breeze. Comes with a louver that automatically moves left and right and right hand louvers, so wind will flow through the entire room. You can choose between 3 kinds of driving modes: continuous mode, rhythm mode and sleep mode. 4 levels of wind strength can be switched. Comes with a convenient shut-off timer. Set up in 1, 2, 4, and 8 hours. Tank can be removed during cleaning.
