Quilo 3in1 Super Quiet Energy Efficient Portable Tower Fan & Evaporative Cooler & Humidifier

I live in the High Desert of California, and this is the best room-sized stand-alone evaporative cooler I have found. Nothing else comes close for ease of operation, low-noise operation and effectiveness. On another note, the manufacturer is out of stock with this product, which I desperately needed - but Walmart is not!!! I bought two. Thank you, Walmart!

I love my Quilo!! This is the second year that I have been using it. It is extremely easy to run and has four fan settings. When its hot, I run the turbo setting and boy does it blow out some nice cool air. It is extremely important to remember that this is not technically an "air conditioner." It is a swamp cooler and runs on the rules of all swamp coolers. The humidity needs to be 55% or less in order for the air to be nice and cold. For most people, it will not cool off the room so much, but cools off the space around you, so its important to have it sitting nearby. The lower the outdoor humidity, the better this unit will work. I live in North Dakota and there is only small windows of time during June and September that it works really at its best. When it gets above 85 degrees outside, our humidity usually goes up too high for this unit to operate well. Use a humidity gauge to help you. It does save me on electricity during the June and September months when I can use it exclusively to keep me cool. I also HIGHLY recommend that you use a bacteriostatic in the water as it prevents mold, and seemingly even calcium deposits from being glued to the inside components. Purchase one designed for water-based coolers and add a couple of teaspoons to the water per gallon. Do routine maintenance as recommended and you will love this unit too!! I soak the filter in white vinegar water for 30 minutes as part of the routine. Its a light-weight unit and easy to clean.
