The CoolZone CZ250 Desktop Dry Misting Fan by SUNHEAT is designed to keep you cool and comfortable during the hot season with many beneficial features. The design, based off the original CoolZone CZ500, was engineered to allow the comfort of dry mist to be used in small places or on a desk. Dry Environments can lead to dehydration and accelerated aging, but the CoolZone misting function uses ultrasonic high frequency oscillation principles to atomize the water into 1-5 micron ultra-fine particles, then diffuses water into the air, leaving you cool and refreshed, but not feeling wet. A remote control is included for convenient and easy use. One year limited warranty.
