HessaireMC18M 1,300 CFM Evaporative Air Cooler

So I'd start out by saying you're going to need to check a map to see if you live in a dry enough area to use this. Does not work in humid environments, not a chance. Secondly you need to draw in dry air from outside, humidify it with cold water, and have a place for it to escape (google search evaporative coolers beforehand). If you use this in a closed environment it will not work and make your room no cooler and incredibly, yes incredibly, humid instead. Where this really shines is in a dry place like Colorado with dry air and lower evening temperatures. Many temperature sensitive areas have been seeing much higher temperatures from climate change than builders (decades ago) anticipated, resulting in heaters but no AC units, and record breaking highs each year. That's where this gem comes in. If you really want it cold you can put a ton of ice in with the water. It's as loud as a regular box fan, which I personally don't have a problem with. And if you don't have AC in your house or apartment, it might turn out to be your new favorite fan. Once we move into a new house, this beauty is going on the back deck for hot summer days, but for now it's used every evening to bring our temps down to a comfortable level on the main floor. If you need more you can look at portable AC units (Black and Decker makes a good one BTW) but they use a lot of electricity and require a window or door for a heat exchange duct and adapter. We have those upstairs (where we can install them easily). Good luck to you! For what it is, where it's operating (again check a map), it's a great swamp cooler! Highly recommend!

I was a bit hesitant in seeing some of the reviews but I determined that some of the reviewer’s must not be very familiar with how swamp coolers work. This is a great cheap evaporative cooler! as with any swamp cooler you must prime it first which means you must set the pump action on for a couple minutes to saturate the filter with water before turning the dial to the fan with water drop symbol. I read several reviews on here which stated that the knob indicators are backwards- that’s incorrect the knob is fully functional in the manner in which it is supposed to be used- prime function pump is a water drop symbol, then there’s two fan only settings ( High and low) and two fan with pump settings (low and High) then the off switch.I Love that the water indicator is in the front of the unit to show how much water is in the cooler as swamp coolers only work if there is water. This machine has a Nice 5 gallon tank and it does suck up a lot of water (about 4 gallons in 4 hours) on the High setting ( that’s normal) The noise level is the same as any other crap cooler we’ve used before, I actually like the soothing waterfall sound it makes.The ONLY con so far is that the door to fill the machine with water is a cheap little plastic door with a not so great flimsy plastic tab handle to open/close That will probably break but It’s been over 100° here in the southwest this week and without A/C this unit has kept our Adobe house ( which traps heat) a comfy 75. As with any portable swamp cooler, you should have it in front of an open window/ door for inside use along with a cracked window to avoid humid mugginess. We Look forward to using this evap cooler during the hot heatwave we are expecting, we might even purchase another for outside use now. Shipment came in a day early too! Great value for the money and if you live in dry heat I definitely recommend

It's a very simple device, but it does its job very well. I wouldn't say it's a replacement for an A/C unit, but even just running in fan-only made the room it's in noticeably cooler (note: mine is being used in a medium-sized room to great effect. If you're trying to cool a larger room or maybe many rooms, you might want to consider buying at least a couple units). Not sure the how much adding the water does to improve performance, but I'll take the added humidity. Overall, well worth the money!

Ordered this to use in our bedroom in the summer as our room was an add on so it got a little warmer than we wanted. Set this thing up, pointed it at the bed and it works great. Filled it up once a day going to bed and it lasted all night(8 hours) with the tank full. Things to know. it is throwing a lot of moisture in the air, so we noticed the blanket where it was hitting more or less damp. Not enough to leave water on your hand when touching it but just wanted to let you know. In later months when it was hot in the day and got cooler in the night, you will notice the air is heavy. Like when you go out and there is a heavy fog outside. But never had issues with mildew or moisture in walls. The size of the room will depend on that. We also used it to help the main unit in the living room when it was above 100 in the heat of the day. Fan is a little louder than a standard standup fan and you can hear the water running. But after a bit, it was actually making us go to sleep faster with the water running. Had to get used to it being gone when it got cold.

So this thing works great in a 12x30 insulated trailer at 7,000 feet in Arizona. If you're sitting in front of it. But seriously does help a ton. But they charge $40 for a new, cheap, paper filter. FYI

Our air conditioner went out with temps hovering around 108 degrees outside. We suffered through with just fans for a few days until inside temps got up to 90 degrees. I ordered this, was delivered in five days and it has been a lifesaver for us. We do have to use it about 10-12 feet away from us because our great room is pretty big and it won't really cool down the whole room. Plus we have "open concept" to the kitchen. Anyway, it has cooled the room down from 90 to 86 but feels cooler since we are getting cooler air blowing right on us. Warning though; it uses a lot of water and I mean a lot!! We put a few gallons of water in the frig and fill the cooler about every 3 hours. Businesses are having trouble getting parts or new units so I don't know how much longer we will have to use this but it has definitely made it more comfortable for us. Once we get our new a/c installed, my husband said he will use it when he is working in the garage. Win Win!!
