Keep the air around you cool inside and outside your home. With the Hess Aire Portable Evaporative Air Cooler, you can stay cool inside your home, out on your patio, or at your campsite. Just plug it in and you're ready to chill. Evaporative coolers are more commonly known as "swamp coolers." These air cooling systems cool warm, stale air with natural evaporation. As water inside the swamp cooler evaporates into the air circulating through the cooling system, the air lowers in temperature. Evaporative wet air coolers are ideal for areas with low humidity since water must be able to evaporate easily. The MC37M air cooler can cool areas as large as 1,600 square feet. The fan draws air in and circulates it back out at a rate of 5,300 cubic square feet per minute. This portable swamp cooler has a 14.6-gallon water reservoir that you can fill through the cooler's manual water fill or through your garden hose connected to its water hose adapter. Get the cooling you need thanks to 4 fan-only settings and 2 evaporative settings. The air vents also oscillate to direct air throughout your room or space. This portable evaporative cooler moves where you need it thanks to its lightweight design, heavy-duty wheels, and convenient handle. Incredibly mobile, this portable swamp cooler weighs only 57 pounds and measures 28 inches long, 17 inches wide, and 45 inches tall.
