Keep the air around you cool inside and outside your home. With the Hessaire Portable Outdoor Evaporative Cooler Humidifier, you can stay cool out on your patio or at your campsite. Just plug it in and you're ready to chill. This portable air cooling system cools warm, stale air with natural evaporation. As the water inside the evaporative cooler evaporates into the air circulating through the cooling system, the air lowers in temperature. 3 simple rotary controls allow the fan to be on high, medium, or low pump, and oscillation motor can be controlled independently. This Hessaire outdoor humidifier has a 10.3-gallon water tank capacity that has a garden hose hook-up with a float valve for a continuous water fill. 3-sided firm high-density cooling pads increase evaporative surface area generating cooler air. This evaporative wet air cooler is ideal for areas with low humidity since water must be able to evaporate easily. This Hessaire Outdoor Cooler Humidifier moves where you need it thanks to its lightweight design, heavy-duty wheels, and convenient handle.
