This 3-in-1 evaporative air cooler combines a fan, cooler, and humidifier in one unit, offering three cooling modes (air-cooled/water-cooled/ice crystal). Featuring a three-sided evaporative cooling pad design with two large-capacity ice crystal boxes, it accelerates heat absorption and moisture evaporation, transforming dry, hot air into cool, humid air. The unit supports a 110-degree wide-angle automatic oscillation, adjustable both horizontally and vertically, with an airflow of up to 3000 cubic feet per minute, covering a maximum area of 950 square feet, suitable for large spaces such as living rooms, garages, and patios. The extra-large 16-gallon water tank allows for manual top-filling or continuous water supply via an external garden hose, and a transparent water level window allows for easy monitoring of the water level. It also features three fan speed settings, a 24-hour timer, and four smooth-slip casters for easy movement.
