Works great in Colorado, even in 100 degree weather

I noticed all the bad reviews on evaporative coolers but having lived in a dry climate most of my life (Colorado), I can tell you this is a high quality EC and any decent EC will work fine if you follow a couple of rules. Please understand these are coming from people in non-humid climates or people who are in dry climates and don't understand how these work differently than ACs.

TIP 1: Leave two windows cracked open for cross ventilation - This would be stupid if we were talking about AC's but if a EC is left running in a closed up house or room, it will make the room humid and not cool it down. You want to have dry (outdoor) air come in through the EC so it cools down the air and blows it through the room. When it cools the air down, it makes a little more humid than it was before so you also want a cross draft so the warm air and any humidity has a place to escape. I put my EC about a foot in front of a cracked window so it gets a fresh supply of dry air and I leave another window cracked open on the other side of the room so warm and humid air will escape. If it gets very hot outside I sometimes close the cracked windows until it gets a little too humid for my liking then open them again - this method works well for me but your milage may vary.

TIP 2: Use ice water in the water reservoir - Putting ice and or cooling packs in the reservoir along with water will help keep the water cold which in turn make the EC work more efficiently.

TIP 3: Clean your EC out occasionally - ECs will accumulate dust and dirt from the air so it if the air it's blowing out smells dusty or is causing allergies it probably just needs a good rinse. Fortunately this unit is very easy to clean.

LIMITATION 1: Won't work if it's humid. Get an AC if you live in a humid climate.

LIMITATION 2: Won't cool down 105ºF air down to 65ºF - No EC will do this or at least not in a reasonable amount of time. If you follow my tips though, you can get 105 degrees down to 78.

ECs are cheaper, more efficient and better for the environment than AC's but definitely have their limitations. If evaporative coolers are right for you, this a is a good buy.
