Product Description
Evaporative cooling fans are designed to pull hot, dry air through a water-soaked media filter using a water pump and fan. As the water evaporates into the air, the air's temperature will lower. They are optimal when used in hot, dry climates used to filter ambient air while increasing the condensation and delivering cool airflow. Evaporative cooling fans do not use refrigerants to remove heat like an air conditioner, so they are less effective in high humidity areas.
Hessaire’s MC37M is the best and most effective cooling fan on the market for its size. It’s compact and yet packs a powerful blast of cooling with a patented winged prop design and three panels of high-density rigid media. Take it on the go easily with its four casters. It features oscillating louvers to cover a wide area quietly and efficiently. The manual controls make it easy for you to adjust between the four temperature settings to obtain optimal cooling anywhere you take the MC37M Evaporative Cooler.
Cooling the air is only a part of the process; propelling the chilled air into your space is what brings you needed relief. Specially engineered features from Hessaire allows this mobile evaporative cooler to provide an airflow of 3,100 CFM to your area. Proprietary fan propeller design with winglets throws the blast of cool air further and yet is very quiet. Additionally, the air swing delivery system moves cool air left to right across the room to ensure that air is evenly distributed.

There was a problem filtering reviews right now. Please try again later.
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.
=====================
edit: Water stopped pumping on 11th day I've used this. I have yet to open it up and see if a pipe fell off or the pump just died. It sounds like the pump is working, but no water flow. Very disappointed for the money. Not unexpected since this thing is so cheaply built, but I'd hoped it would have lasted at least the whole summer. Right now 80F (27C) when outside environment is 92F (34C) at RH12%
======================
This is pretty cheaply made, but is sufficient for what it does. Right now I have it temporarily in a 2,000sf house and it kept the temperature at 78F (26C) when outside environment is 93F (34C) at RH13%, so I expect it to work in a 900sqf house just as well or better.
I'd say it works great but am worried about longevity. My parents had one that lasted 4+ decades, but it was built in the 60's or 70's.
This is much more economical to run than an AC, but does not blow at 55F (13C) like they do. It is much more environmentally friendly unless it winds up failing in 5 years and I end up paying for it 8 times.
Easy to setup and connect. Arrives mostly assembled (coasters/wheels under bottom of cooler). 4 fan speeds. High speed is loud enough to make it difficult to hear general conservations levels if seated near the cooler. It will cool the inside of an 800sq house at least 15F but creates high levels of humidty in the house. Works great for outdoor garages, patios, activities. Makes it tolerable to sit outside in Tucson when it's 111F (if you sit in the line of the fan output). Also bought a filter (RV in-line hose filter) and pressure regulator to connect with a garden hose. There is no built-in water level shut-off for when it is full. It claims it has an auto shut-off when water level gets too low. Will hold 10 gallons of water which makes it very heavy when full. Wheels roll it well on smooth/flat ground. Very difficult to move on gravel, rock, outside, etc. Does not have designated handles on the sides for lifting/carry. Have been unable to work in my workshop in Tucson during the summer because of the extreme heat. This cooler changed that. I open one of my doors to the shop and put the cooler on high. This greatly reduces the humidity substantially and cools the immediate area almost 15F.

I find the directions are lacking, and they need to be more specific on how it is used for indoors. We didn't realize you needed to use it with an open window and the house got so humid it was like a swamp, LOL! Then I had to do some research online and re-read the minimal instructions before I understood how to use it properly. ;)
