on 2016-06-03 Very compact cooler, it is rated higher on CFM/Sq Ft then other units in its price range and performs well.
Background; I live in Arizona, currently in Yuma. I have owned many evaporative coolers over the years and have owned an MCP59 for 5 months. MCP59 is the same cooler as the MCP44 but with a 1/2 HP motor vs the MCP44 1/3 HP motor. Currently the MCP59 isn't on amazon.
To start, this is an evaporative cooler and it performs the same tasks as a classic style side draft windows unit still sold today. It is also similarly priced as a steel unit and shares many stander cooler components. Installation is also very similar to most units and should take 1 to 2 hours in general. The temperature is 112 F in Yuma today and my 1700 sq ft house is 80 F with the motor on medium speed all day. On medium fan setting with the pump on, the cooler draws about 302 W at 117 V. This is the setting I have it on most of the time. I would also assume the medium setting on the 1/3 HP motor is going to move a little less air and draw even less power. It still uses the same cooling method as other evaperative coolers so it share the same PROs/CONs vs air conditioning.
I am going to focus this review on what sets this unit apart; plastic construction, slim size, ridge filter media, purge pump prewired, built in micro controller, capacitive buttons, and replay board.
1. Plastic construction - A big pro from me because the biggest killer of steel units in rust. Since most evap coolers are completely rebuild-able, they do not get replace until they are rusted out beyond repair. Regular maintenance will prolong the life of the unit but unfortunately most units do not get serviced enough. That being said, most plastic doesn't hold up to the suns UV rays, especially in Arizona. My unit is installed under a well covered porch and doesn't get any direct sun light. Only time will tell how long this will last but after installing and using this unit I am optimistic.
2. Slim design - Also a pro from me as it is installed on my porch and it is not a big eyesore like its steel full size counterpart. The compromise here is to accomplish this the unit uses a direct drive motor mounted in the window sill. This is uncommon in evap coolers and means there is no squirrel cage or belt. This removes the flexibility of being able to under drive or over drive the unit with a pulley change and as you may have read this unit is very loud on the high setting. I think this is a combination of the fan type and the fan being half way in the house. The motor does have 3 speeds to compensate for this but depending on where you install the cooler in your house high is almost unusable because of the noise.
3. Ridge filter media - Best filter media by far. You can research this yourself with a quick google search. It last longer and cools better then everything else. The down side is replacement of these custom sided pads is expensive, there is a link to it. Essick Air Products Pad Media Replacement Mcp44 MCP44-PAD
Hopefully I will get a few years out of them because I need to buy replacements.
4. Purge pump prewired - (READ THIS,READ THIS,READ THIS). Sorry about the caps but this is a important note even for a experienced evap cooler installer. This unit is wired for a purge pump but it is not included with the unit. The manufacturer says you have to use this kit MasterCool Purge Pump Kit
. The kit is over priced and not necessary but that does not mean a standard purge pump kit will work in this system either. The mirco-controller sends power to the purge pump on a internal timer as opposed to a standard purge pump kit with a build in timer. So you need to use a low volume main pump as a purge pump, I would go with something like a dial 5000 pump. These are about half the price of the manufacturer's recommend kit. I had an old one laying and it works great.
5. Micro controller, capacitive buttons, and replay board - This is a nice feature that I was skeptical about at first. Mostly because I like to use my cooler on a timer or a thermostat depending on the situation. I do have to go out of town for work and like to give my dogs some cold air during the day. My concern was if I used a simple mechanical outlet timer, it would disconnected and then reconnected the cooler's power and the cooler would not return to the same pump and fan setting. It turns out the micro controller does save its last setting, which means you can do a lot with the unit. I have since installed a $8 thermostat/relay board that I wired to switch the 5v power from the replay board to the micro-controller, effectively turning the whole unit off and on. This works pretty well but I might change it to just switch the pump off and on instead. That way I can leave the fan on to circulate cool air at night and save power and water. This is a pretty simple mod of most DIYer as both circuit boards are well labeled.
To sum it up, this is a very compact cooler, it is rated higher on CFM/Sq Ft then other units in its price range and performs well.

I have had this working for two months now. It cools my house from 100 degrees and 15% humidity outside to 75 degrees inside. What a space saver. I installed it as a thru wall unit.

The pump stopped working within 6 months and no way to contact the seller.

Poor design, VERY LOUD!
I purchased this from a large home improvement center. I didn't find many reviews online before I made my purchase but I did call the manufacturer. I was concerned that such a compact design might not be capable of performing as well as the large conventional evap cooler it would replace on my home. They assured me that because this cooler uses high performance rigid media pads it does cool as well as a much larger conventional cooler. I took the chance and purchased one. While installing it I found that 3 of the 4 plastic fan motor mounts were completely broken off and the flimsy plastic nut on the fourth mount was also broken. There was nothing solid connecting the heaviest part of the cooler to the housing! Using larger and all metal bolts and fender washers I was able to reattach the fan motor assembly. I planed to contact the manufacturer for a replacement fan housing later but I just wanted to get it installed and working for now. Anything can be broken by rough handling during shipping but I believe the plastic motor mounts on this product are much too weak and will probably break eventually due to normal vibration of the cooler. I also think there is no excuse for using plastic nuts with the stainless steel motor mount bolts. The entire housing and frame feels flimsy as well. I was attracted to this unit because it is made of plastic and therefore can never rust out like normal swamp coolers do but the plastic on this seems too thin and flexible.
Once I finished the installation and turned it on the really big problem with this model came out. The noise! This thing is LOUD! I can't imagine sleeping anywhere near this thing. Even when it's running on it's lowest speed it makes this loud, annoying droning sound. When it's on high you can forget having a normal conversation in the same room. I had to crank the TV way up to hear it at all. It's a ridiculous amount of noise for a home cooler. Using my sound level meter at ten feet from this cooler I got 68db on low, 71db on medium and 75db on high. That's crazy loud for something that is going to run all day and maybe through the night inside your home. It was a lot of work, but I removed it, returned it and purchased another large conventional all steel evap cooler and I am very happy with it's performance and noise level. Any evap cooler is going to make more noise than a regular refrigeration type air conditioner because evaporative coolers move so much more air but the type of fan they use in this Mastercool evap cooler just makes way too much noise. The larger conventional evap cooler I replaced it with is far quieter even though it actually moves 1,000 cfm more air! My new conventional cooler measured only 59db on low and 67db on high. I can deal with that.

POOR ELECTRICAL CONTROL WORKMANSHIP
I just purchased this at Lowe's, got it installed and then disaster. when I pressed the pump to on, the fan went crazy on high speed, but the low speed light was on? (It has three speeds)...after three minutes of extreme high speed, the fan hut down? I then shut it down and started the fan on low without the pump being on. It worked great, but the I turned on the pump and the fan went crazy fast again, then after three minutes the fan quit? Called the Manufacture (Essex) and was told the fan switch and controller was bad and they would ship me a new one, but I have to totally take apart the unit to fix it. I asked where the Controller assembly was made, I was told "China!" Well, another piece of poor workmanship from China where no inspections are done and we all get crappy products. So, I have a bran new product with hours taken to instal, and it fails the first time I use it!

Pretty "cool" unit, but...
Lightweight. I was able to install this by myself and I have some disability issues.
Will never rust out like the metal "swamp coolers" I grew up with in the desert area around El Paso where everyone had evaporative coolers when I was a kid and everyone had to fight rust in their coolers and do lots of maintenance.
Compact design doesn't "pooch-out" very far out of the exterior wall and interior wall.
Although one reviewer stated these are "very loud" I don't think they are and I suggest they are "not noisy."
Cools great in dry parts of the country.
The electrical control unit is made in ðŸ‡¨ðŸ‡³ and mine quit working 6 weeks after I installed it. I purchased (May 8, 2017) a replacement unit that the customer support rep said was redesigned. Still made in ðŸ‡¨ðŸ‡³ and probably in some sweat shop that doesn't have a quality-control department. I hope this one (set me back $75) will last at least a year. I've owned my original cooler 2.5 years now.
The plastic snaps that hold the small electric control unit in place, two out of four broke when I pulled them back gently to get the controller out. (This is a cheap design flaw and at the bare minimum, the controller should be held in place by some hefty screws instead.
After 18 months of the outside part being exposed to sunlight, I'm noticing the plastic isn't holding up really great, and I suspect the factory in China does NOT add a UV inhibitor additive in the "soup" that the plastic parts are made out of. In fact today as I was working on the interior part of the cooler, I broke one of the slots on the vent side that is not even exposed to sunlight.
The evaporative pads work really great BUT they are expensive and you can't buy them at your local hardware store, like you can for a regular "swamp cooler."
I use this cooler in a metal shed near Abilene, TX that is painted dark green and gets wicked-hot. I built the shed to put my car in while it is parked and charging and since it is an EV (electric vehicle) it's critical that the car not get hot when it's charging. This cooler works GREAT in the shed for keeping my EV from melting and the large lithium battery from heat. Typically, when it 100 degrees outside, I can measure a 30 degree drop on the remote temperature guage I leave in my car to keep tabs on the heat.
Would I install one of these in my home? Answer is "no" unless I lived in the desert area from El Paso to Yuma, AZ. Where I live is a little too humid for this to be comfortable for me to use in my house, but it works great in my car shed and does not use anywhere near the energy that conventional refrigerated air conditionsers use.
Please note the attached photos show this unit as I am installing the new controller (in the inside of my shed) and a new water pump on the outside of the shed. The outside housing is a real "bear" to remove and install alone. The inside part is difficult to reinstall because of the extensive conglomeration of wires that have to literally stuffed back into tight and difficult to reach voids inside the front facing.

I wouldn't buy this cooler. I replaced a similar CFM conventional evaporative cooler with this slim model. The pad area is too small and gets overwhelmed by the fan. This lowers the operating efficiency even at low humidity (10%) outside. I've had swamp coolers for 40 years in all parts of the country so I do have some experience. The conventional cooler, which I had for 8 years would keep the house near 76 on days where it was 108 and 10% humidity outside ( my experience is a 30 degree drop when conditions are optimal). This slim model has the house at 81 when it was 108 and 10% humidity outside. I've taken it all apart and yes the pads are wet and there are no blockages.And don't even try it on high fan speed because it just blows warm air. This is another symptom of insuffcient pad area. This unit is more suited to Albuquerque where relative humidity is around 6% most of the time.

Excellent coolers and they save money
We love this cooler. We actually purchased one to try it, then purchased a second one since it works so well., Our house is long and somewhat divided in half. We cut holes in the house and permanently mounted them, one on each side of the wall that runs down the center. They are extremely efficient, and cool the 2400 sq ft house nicely, and we generally just run one at a time. We live in the low desert, and they cool efficiently up to about 110-115 degrees. We have very hard water here, so we installed a purge pump for each, and just purchased a cheap pump from Home Depot that works great. It is pre-wired and automatically runs the purge pump on its own timer, so you don't have to purchase an actual purge pump, just a standard pump. We have been using them for 3 years now, and are just changing the pads. They run 24/7 all summer and our house is quite comfortable. They have also saved us hundreds each month on the electric bill, not needing to use the AC.

Poorly designed plastic parts break easily and do not fit together well
I bought this from an online national supply house (Zorro which is owned by grainger). Poorly designed plastic parts break easily and do not fit together well. Lots of leaks and holes, if you do manage to tape it together well enough to turn it on, it does cool pretty good. The outside temp is right now is about 98, and it is cooling it to about 75, with 15% humamidity and a 45 dew point. So that is equal to 85% direct saturation efficiency, much better than those old school coolers.

A VERY UNSATISFACTORY PRODUCT
The electrical control was defective, I requested a replacement and I had to pay for shipping to get the replacement in less than two weeks, really bad service. the low setting is way too high and very noisy. There is no way to direct the direction of the air into the room. The whole unit is poorly made and not an easy install. I WOULDN'T BUY THIS UNIT AGAIN AND I EXPECT I WILL REPLACE IT WITH A MORE SUITABLE UNIT BEFORE NEXT SUMMER.
