Rated 3.8 out of 5 by 40 reviewers.
Rated 5.0 out of 5.0 by better tthan we thought Although larger than the unit being replaced, we were concerned that the rated square footage was less than our house size but since this is used only to supplement the refrigeration and installation size was important, we decided try this small model. No worries! Air flow is more than adequate. Do be careful installing the plastic drain fitting. It's not possible to get it really tight and it can loosen when tightening a drain hose. It needs too be held on the inside so put on a hose before closing the back. April 14, 2015
Rated 5.0 out of 5.0 by Great in low humidity places! I set this up the beginning of May in Denver, CO. It works great! Last year I had a portable evaporative cooler that was horrible (It would just circulate hot humid air.. yuck). DO NOT BUY A SWAMP COOLER IF YOU LIVE IN A HUMID PLACE THEY DO NOT WORK IN HUMID PLACE (FL I'm looking at you!). Not much to setup (Other than running a water line). Easy to setup and I haven't had to service it yet but it looks simple to clean and maintain too. Fantastic! Highly suggest you get one before the summer hits you in the face! May 26, 2013
Rated 5.0 out of 5.0 Cool Cool Summer! I bought this about a week ago and installed the very next day! It great for keeping my house cool upstairs - No more sweaty nights on top of the sheets! Was easier to install than putting together a bookcase and I cracked the window in my bedroom about 3 inches and the air moves right through my room and humidity carries out. Yeah make sure to crack a window just a few inches so the air will flow in the direction you want, otherwise it will just get humid and act as a fan. Great for Denver weather, since it's so dry. The length of the cord could have been a little longer (just saying). July 6, 2012
Rated 1.0 out of 5.0 by Do NOT buy this product Living in Las Vegas, we are not strangers to evaporative coolers and find them preferable to reconditioned air. Generally, they work great and, when maintenance is required, prove to be simple and accessible. NOT SO with this Champion/Essick Air model. Problem number 1: the back louvered panel offers the only access to the inside. After removing the single screw at the top (marked), we fought to get the panel off. It eventually yielded to the use of a putty trowel. The problem, as we discovered, was the incredibly poor construction of the parts. Problem number 2: during the set-up, we discovered that the float valve stem had to be inserted through the media in the side - and that the side panels are not removable without literally taking the box apart. Problem number 3: having managed to complete the set-up and fill the box with water, we plugged in the cooler. The pump operated well, but when the fan was started, a major issue was exposed. This is a design flaw, exacerbated by shoddy construction: instead of a single squirrel cage, this model has two, attached to either side of the motor and supported by brackets. One cage was properly seated - the other was listing to a degree that it knocked against the fan housing when it turned. This discovery led to problem number 4 . . . In order to access the motor/cage/bracket assembly, the ENTIRE box has to be disassembled. Why? Because: the screws that hold the fan housing are behind the front panel tunnel assembly . . . and the mounting brackets for the housing are screwed into the side panels, which have to be removed in order to disengage the bracket from the lip of the panel after it is unscrewed . . . but first you have to remove the top of the box so you can remove the side panels. After performing this vivisection on the machine, we discovered that the welded housing that holds the motor/cage brackets was crooked - which meant there was no way to adjust the listing cage. It didn't matter at that point, though, as we realized that the "yearly oiling" of the motor would require this same disassembly - that even replacing the pads would be a nightmare. Champion makes some good products - but this is NOT one of them. June 1, 2014
Rated 4.0 out of 5.0 Works Great...Economical to Operate I've purchased 2 or 3 of these coolers in the past few years for different applications. As long as you're not trying to cool a large house, they work great. We use it in Arizona in April through June, and again in September and October. Generally, July and August are too humid for effective use of an evaporative cooler. It adds very little to our electric bill each month...way cheaper than refrigeration. Swamp Cooler hints...keep a window open at the opposite end of the house of the cooler so the cool air will flow through the whole home. Rinse out the cooler once per week...drain the old water out. It tends to get concentrated with minerals that shorten pad life and cooling effectiveness. Keep the cooler on all night and you'll have a cold house in the morning. Turn off the cooler and close up the house and it should stay cool for many hours. June 9, 2010
Rated 1.0 out of 5.0 by Bad design. The blower sucked water off of the pads and into the motor. The motor did not last a month. I had to design and install shields to keep the water out of the blower. The clearance between the blower and the pads is less than three inches. June 6, 2014
Rated 5.0 out of 5.0 by works great Use this in my 2 car garage. Mounted it on the side wall high up thru wall. Nice having a cool place for the cars in the 115 degree days. It will usually lower the outside temp about 30 degrees when the humidity is under 20%. I also have a chest freezer in the garage. Installed a purge pump, and ran a 1/2" PVC line to the backyard for the drain water, as I didn't want it going down the driveway. Don't have a thermo on it yet, so I use a 1500 watt wall timer.

Rated 3.0 out of 5.0 by You need to provide a vent You people complaining about the CFM. This is a once thru unit, you cannot ciculate through an evaporative cooler. In order for it to blow air in, you have to provide for air to blow out. Open a window across the house enough that you feel the air slowly leaving the house. If you close up your house this unit will not work. Also you have to be somewhere dry, like less than 20% RH on the hot days. And if your night RH rises to 70% it might not do much through the night, just use a regular fan then. July 3, 2012
