This is a great portable cooler. I debated whether to get a whole home cooler or just a portable cooler. I’m glad I went this route as many reviews had varying ratings. Here’s my situation which may help others decide. I have a 2 story home. The upstairs is approximately 900 sq ft and is basically an open floor plan loft which has a bedroom, bathroom, and livingroom area. The downstairs is about 2200 sq ft that has the livingroom and kitchen centrally located with other rooms located around this central location. I explain this because I get great circulation in my home due to the layout. I live in SW Colorado and our typical humidity in the summer season is under 20% and most of my home never gets direct sun for too long in one location. Due to this, my home rarely gets warm until about 3-4pm in the west side. And it’s only gets a bit warm for me until about 8-9pm when the heat breaks due to the sun setting. So with that info, I bought the unit for approximately 900 sq ft. I placed my unit in the western most room and have it facing at an angle towards my centrally located rooms which is the livingroom and kitchen. On Low Setting, this thing easily knocks the heat out on the main floor. I’ve not had to use the Medium or High Settings what-so-ever even in mid to high 90s. I run a window fan upstairs to just pull heat out of the upstairs, run my ceiling fans (2) per normal, and typically I don’t have to open up any windows downstairs. While it’s recommended to run in front of an open door or window, I never do. When it begins to cool off in the evening, I may or may not open up a window while this thing is running. Due to how dry it is out here, typically I do not get any mugginess in the home from running as I do. Your situation may differ depending on humidity. Installation of the wheels was a breeze. The only thing I’d suggest is DO NOT use power tools such as a drill driver and DO NOT over tighten the screws for the wheels. I just hand tightened to snug and had zero issues with stripping out the plastic. You just have to take care. My wheels were loose within the box as the plastic storage cover was not securely screwed down. It was a non-issue for me and I didn’t have to build any wood base. The only real issue I had was the whole thing is molded plastic and my water storage section has a small area that is a tad warped. It was also a non-issue for me. As for loudness... I can hear my tv just fine with it on Low and I’m sure would hear everything just fine on the other settings. When I set a box fan next to it, I can hear the box fan on low over the cooler to give ya an idea. The only part that I find a bit annoying is the oscillating setting. It sounds like plastic rubbing on plastic with just little creaks. I’m sure a little Teflon spray, chain wax spray, or even a little WD-40 could curb that, but I don’t bother with the setting. All in all this is a great cooler and I waited to pick it up when it had a price reduction. It cools pretty much my entire downstairs, with the central house receiving the most benefit and the hallway and rooms that the breeze is directed towards in my home. I’d say it easily knocks the home temp into the mid to low 70s for about 1500 of the almost 2200 square feet I have in the main level and that’s on low. The remaining 700 sq ft is cooler, but not as noticeable. It could be if I ran it on the other settings, but no one is in those rooms or upstairs until after 9pm and my house is opened up at that point since I get temp drops of 25-30+ degrees when that sun sets. If you have my situation, this thing will easily cool your main level of your home beyond it’s minimums depending on your situation. I’ll end this review with this thought, just take into consideration your home layout, your typical humidity, the rooms that actually need cooling during the times it’s uncomfortable for you. Each situation is different. My cooler usually only gets run on 85+ degree days for about 4-6 hours, due to my locale. Once the outside temp drops into the 70s, my home gets opened up. Your situation may vary.

OK, let's get the basics out of the way. Evaporative (swamp) coolers work best when you live in a dry climate. If you live in an area with high humidity, they don't make the air cooler, they just make it wetter. Got it? I'm baffled by the bad reviews from people living in 80-100% humidity complaining about a swamp cooler not cooling. If you live in Mississippi, don't buy this. It won't work. You need refrigerated air. But for those of us in the desert SW, this unit is a Godsend. It cools VERY well. It holds 10 gallons of water, or you can hook it directly to a hose (recommended). Turn the pump on first, let it soak the pads for about 1 minute, and turn the fan on. The pump moves a lot of water, and soaks the pads quickly. The pad material is very efficient. So efficient, in fact, that I estimate the unit uses about a gallon of water every 15 minutes. See why hooking it to the hose is a good idea? But it also has a gauge where you can tell how much water is in the unit at a glance. If you plan on using it indoors, position it where it can draw in hot outdoor air and exhaust through another opening, like a window or door. I use it in my garage and storage barn, and just place it in front of the access door. Draws air in from the bottom, exhausts it out the top. Easy peasy. Cools the area without getting too muggy. It has 3 fan speeds, and moves a LOT of air. The low speed is usually sufficient. And it works fantastic outdoors. Yard work, wrenching on the car, enjoying the patio, you name it....this unit will keep you comfortable. Build quality seems good. I like that it's plastic and won't rust. If I have any complaint, the plastic seems a bit cheap, and the fit and finish is mediocre. But these are very minor flaws on an otherwise great product. It has locking casters and rolls easily....and when you're ready to move it, just pull the drain plug and let the water out...and then the unit is light weight. All in all, I couldn't be happier with it. My only regret is not buying it ages ago. If you're torn between which portable swamp cooler to buy, go with this one. Excellent bang for the buck!

I waited until the end of summer to leave my review, so I could have an idea of how this evaporative cooler would hold up after months of use. I live in So Cal, and specifically bought this for work. I work in a large outdoor booth without any kind of cooling. After several summers of suffering from sweltering heat, I finally decided to take the plunge and buy a portable swamp cooler. Initially I was hesitant, as a few hundred dollars is a lot to spend on something I’d likely only use for 3 or 4 months. But I am sooo glad I did! This cooler really does blow out cool air! I was surprised and delighted! The wheels glide across the concrete floor with ease, and the drain is easy to plug and unplug. I don’t have access to a hose, so I can’t attest to how the hose connector works. But it’s very easy to add water manually. And no leaks! You can also add small chunks of ice, although I don’t think using ice made much of a difference. Also, the little window showing the amount of water left in the tank is very convenient. Be prepared for the air flow being strong, and a bit loud. Even on low, which is the only setting I used. Being outdoors a little noise is not a big deal. But I think it might be too loud to use indoors. If I have one thing that’s negative, it’s that the latch on the manual fill door, which is only a tiny piece of plastic, broke after a couple of days. All in all, this portable cooler works great and was worth every penny!

It was delivered the day after I ordered it so excellent delivery time! If it weren’t so loud I would give it five stars. You can’t sit right next to it and carry on a conversation. I bought it as a back up for when we have family come to visit. I would have to put it in the other room to be comfortable with the noise. It would be fine for outside or in the shop. I’m sure if it gets hot enough we will use it! Right now it’s 90° in Arizona where I live and we have our swamp cooler running in our house. I expect it to get very hot before the monsoons and I wanted to have the ability to cool off the house if I need to. We have very little humidity so it works great! The review where the man said take it out of the bottom of the box was a great tip. It’s easy to put the casters on and lift the box off the top. It seems very sturdy I’m not concerned with the construction. It worked as soon as I hooked up the water and plugged it in. It only took a few minutes of the pump running to cool off the house. It’s also a good tip to take it out of the box and try it right away. Don’t wait until you need it to try it. I think it’s worth the money and it definitely cools very well!

My partner and I LOVED this swamp cooler. For context, we are renovating a 1970’s house in the mountains of Southern California, which is dry and hot in the summer as it gets the Palm Springs desert heat. I purchased the middle size unit meant for a 950 sq ft location, but used it in a ~500 sq ft open floor plan area with ~15 foot vaulted ceilings, located on the third floor of the house. It worked wonders. Since the house is old, the sun beats on the siding and cooks the inside, but with this we stayed in the upper 70s/low 80s; without it we would easily be hitting 95°. I don’t mind the added humidity, and our indoor temp monitor listed the maximum humidity at around 60%; for me it helps my breathing so I’m fine with that. It was a little noisy, but not nearly as noisy as the portable AC unit I bought. It pushed out so much airflow that the whole floor stayed comfortable. It was a little complicated to fill, as I don’t have the right kind of sink to hook up a hose, but I purchased a dollar water pitcher and it didn’t take much effort to fill it with that. Once the water is halfway used, there is more dripping noise than when it is full. Again, loved the unit and am looking to get another (probably the smaller one) for our downstairs area as it’s far superior to an air conditioning unit which is more costly to run and dries out the air.

I purchased this Evap Cooler to cool off my Greenhouse. The unit came quickly and was easy to setup. The only task is attaching the caster wheels. I connected the hose with the included nozzle and waited for it to fill. Waited.....Waited....Nothing. The hose was turned on, water flowed thru it but the float valve inside of the unit would not open its valve. I added water manually thru the front latch door and the unit did operate. It is very loud. Especially on the highest fan setting. Testing the unit with a sound meter shows between 68 - 75. 75 decibels can be annoyingly loud to some people. I am one of those people. Compare that sound level to A/C powered vacuum cleaner. By comparison, The Honeywell Evap Cooler that I purchased a month ago registers 71 on its highest setting. Decibels are an incremental scale, not linear so there is large difference between 71 and 75 Since its arrival I have been trying to work thru Amazon and Hessaire to get a replacement float valve. Hessaire has no customer service phone number so the requests just go into the website and remain unanswered. Amazon seemed concerned but only offered to replace the entire unit, which is large and heavy. Using the instructions that came with the unit, I tried to adjust the valve. The valve only operated when the unit was almost completely empty and the pump was sucking air instead of water. I tried to adjust it, but it would hit the plastic housing preventing me to raise the ball (like a float valve in a toilet, but entirely plastic) I regret trying to save a few dollars by buying the Hessaire unit instead of another Honeywell. The Honeywell works perfectly and is quieter. One year later, the unit died. It popped the circuit it was on when I tried to turn it on. I ordered a part from Hessaire, two weeks later still waiting for the part. Horrible machine and a waste of money

Purchased for a barn party when my AC wasn’t installed correctly. It did exactly what I hoped it would. Well packaged, easy to put together, and filled with the hose then a large water bottle. The water reservoir is easy to see with the clear window and bright level bubble. There’s a swing option & two fan speeds. I put it in an area approx 450 sq feet with 8-12’ ceilings. Literally cooled it 15’. You need to keep an eye on the water level but it lasted a couple hours without needing to be filled. The blower fan is great, it’s loud, but with the cool air coming out of it and music on, I barely noticed. Caster with a locking feature are great for easy moving. Attaching a little video with me holding a cloth napkin 12’ from it and the movement of the napkin when the swing hit it. Additionally, I rented three same sized “cooling” machines from a rental company for the other part of the barn at $100 ea plus $195 delivery fee. This unit I purchased, blew those machines out of the water!! Had I known, I’d have bought two more of these units! Highly recommend!

I’ve seen other reviews of people complaining about it making their rooms humid and leaving negative reviews, but that isn’t a flaw with the product. This type of cooler works by evaporating the water you put into it, in turn removing heat from the air. As such, its intended use is as a spot cooler either outdoors or in a well ventilated area (such as a shed with the door open). And let me tell you, this cooler does an excellent job at spot cooling. On a hot day it’s the best thing ever to take a break and cool down in front of this cooler. I’ve also seen people complaining about how loud it is, but again, it’s designed to be used outdoors and I don’t think it’s even close to too loud when used as such. The plastic case seems a little bit flimsy, but for the price I don’t think it’s too bad. For filling, this cooler has a brass port to attach a hose, and a float valve to keep it full without overfilling. It also has a door on the front so that you can put water in that way. I normally just fill it with a hose from the door, because it’s only used a couple times a day and the water reservoir is large enough to last 2 to 3 hours of runtime on the highest fan setting. That way I don’t have to run a hose to it. Anyway, this makes a great stationary spot cooler for use in a shed, I just wouldn’t recommend using it as a portable cooler as I’d be worried that the case would be damaged rather quickly. Overall I’m happy with it and would recommend it to anyone who works outdoors in a hot place with low humidity.
