Hessaire MC37M Indoor or Outdoor Portable Oscillating Evaporative Swamp Air Cooler for 950 Square Feet of Space with Water Reservoir

I can’t be happier with this purchase. Works great, especially on the hot days. We put it on our porch and it cools it 15 degrees. Works better than the portacool unit we have on the back porch, which is 3 times the price and this one bit does the same thing. Depending on humidity outside, water reservoir last 6 hours before needing filled.

This swamp cooler was wonderful. Definitely did what it was made to. Water tank in the bottom was perfect to keep the air chill!

I liked that it humidified the air and cooled down a portion of my great room allowing me to read in a very comfortable atmosphere.It is fairly noisy even at low level. Relatively inexpensive to buy and operate. I added a shut off at the hose inlet and used that to shut off the water overnight. Both pump and fan were turned off and the outside faucet was just barely open. The high pressure from the outside Faucet must have overcome the shut off at the water tank in the unit. Flooded the kitchen the water leaked into the ceiling below soaked through the drywall & dropped the gooey mess on my truck. in spite of all the smoke in the air I had to leave the house open for three days to dry out. I should’ve shut the water off at the outside Faucet & made sure that the pump was turned off so I didn’t end up running it with no water. The open water tank is a problem anytime the unit is moved it sloshes over. I am going to buy a portable air conditioner. No advice given on how to best use the unit. You are on your own to figure it out. Obviously I didn’t. Do not recommend.

I purchased this unit at the beginning of Summer when my AC was out. Replacing the AC takes time in a NYC Co-Op, so this unit was exactly what the Doctor ordered,....literally. The early heatspell of nearly ninety degrees is dangerous to the health and this unit arrived just in time to cool things off, even in the humidity of NYC. Granted, this is not Houston or Tampa, as temps creep up toward a hundred, fans only would not suffice. This cools things down by an estimated fifteen to twenty degrees in half an hour or less. Up to eighty degrees, one only needs to use the fan on this unit. I am confident it will cool at a hundred degrees or more, a rarity fortunately in NYC. It may not be AC cool or cold, but it is cool like a spring breeze and the three speed fan pushes plenty of air around, especially if the swivel function is used. I only use it on the low setting and I am quite alright, even shutting the water evaporative function off in the evenings. It delivers and does so only drawing current for the fan and pump motor. It can save the life of an older person or one who has breathing difficulties. Just let it blow out a distant window or use another fan to pull the humid air out a distant window. It produces a lot of humidity and you should be well aware of this, because it can go through its large tank fairly quickly over a day. The noise level is acceptable on the low setting and it may not be the most attractive thing to look at, but it does its job well and the noise would be no issue in a garage or outdoors. Even if I give it four stars taken down by its looks and moderate noise, this is one of only a few items on Amazon I can so highly recommend. This is a unit all about the practical function of cooling. You get what you pay for and worth the going price.

This product does not function efficiently as was described on the website. It blows very hot air and moisture that it exudes causes mold to build up especially when used in an enclosed place, such as a garage. Will never recommend it to anybody. I used this product in my garage and my garage became hotter than before it was used. Nobody can enter the garage when this product is in use. I had to stop using it just after 1 day. The moisture from this product can cause mold which can be a health risk. I give product a NO Star rating.

I had one of these units 3 years ago. We used it for an event in a tent for 16 people on a very warm Miami day. It definitely kept things comfortable. It’s not an AC. But it did keep the air several degrees cooler. It’s a little noisy but a fair trade off. So after the event I gave to my son. Fast forward and a new event and I ordered another one. The day it arrived, my son brought his over to use for the event. So we decided to return. I read a review here where the company made it difficult to return. NOT SO! I did the return and received a FedEx code to drop off. Howver this box is super large and heavy. So I sent a message to the vendor that I needed a FedEx label for a pickup. Seriously, within 5 minutes they sent me a label. I called FedEx and they picked up the next day. So, I wanted to set the record straight. If you need to return within their return period, it’s really no hassle.

Good product and as a single room solution it works, but requires water frequently and you need ventilation otherwise the humidity will be a significant issue.

When I first opened the box, I wasn’t very pleased with the cheap construction. A friend of mine has a porta cool so that is the only comparison that I have. While the porta cool is built way stronger, it does not put out nearly the amount of cool air that this cheaper unit does. The porta cool also comes with a hefty price tag. After I used this on a couple 100 degree days, I could care less about the construction of it, it was a life saverI use this swamp cooler in my garage on hot days and it is 100% worth the money
