Title: Very disappointing
Review: Here in New Mexico where the humidity is often in the single digits, good evaporative coolers can be very effective. Not this one. On a bone-dry day with the temperature in the high 80s, it lowered the temperature in my small 400-square-foot office by only 1 degree Fahrenheit. I am returning it to Amazon.
