Let me start by saying I live in south Louisiana where humidity is insanely high always. This swamp cooler makes my shop much more bearable in the hot summer. So far I’ve used it only when out in my shop so most afternoons. The ice packs work wonders! I would recommend this unit due to it’s features (ice packs, oscillating vent louvers, 3 speeds, separate controls for fan speed, fan power, water pump power, and master power, auto water fill adapter comes included). Cost the same as I could get a 2,100 CFM unit for here locally. Quick shipping and very responsive customer service. Nothing was wrong with the item, I had received a damaged ice pack. Contacted seller and they sent a replacement out right away.

I bought this unit because of it’s ability to add ice packs. The hose connector was missing a piece to connect to a garden hose. However, this company stands by their product because they immediately let me know that my order must have been missing this piece and immediately shipped it to me. Despite this, the swamp cooler works great, and it gets a two thumbs up from my wife, who prior to the arrival of the cooler, refused to sit on the patio when temps went into the 90’s. Operating on high, (which is very very quiet) temperatures in the low 90’s (93 to be exact) dropped to a very comfortable 84 in Central Texas Hill Country heat. The oscillating fan cools the entire 22’ x15’ patio, and evenings outdoors are now quite enjoyable. The ice packs add to the cooling effect. Definitely would buy this one again.

It’s very portable due to the light weight when empty, the pump and design works nice, however after a year of use, the medium and low fan stopped working. I’ve always left it on high but the medium nor low work now. Since idk when but it just shuts off the fan. But the high has a nice breeze to it. Overall worth it for my use. UPDATE: Now the high setting no longer works so therefore the entire thing is useless now. Lasted a little over a year but not worth it.

I ran this thing incredibly hard for 2 years solid.. I mean hard.. it has performed great. I’ve had a few of these and various models/sizes. This one has outperformed what I thought it would. I did have the pump go out on after lots of stress, constant use in a small greenhouse, and salt deposits built up. But, I contacted the company, they had a pump to me in a few days. And with my technical background I was able to swap out the pump to have a fully functional unit again. Customer service was excellent and easy to work with. Fast communication.

I am a retired 71-year-old, managing several properties in an active adult community in Arizona. I had one of two AC units in a house die. I need it replaced. Unfortunately, after calling several AC installers, I was given a three-to-four-week delay for installation. My tenant's senior citizens can't live without AC in Arizona. So, I went online to find something that could bridge the gap and not break the bank. After several hours of shopping online and comparing lots of options, I purchased the 3531 CFM Evaporative Air Cooler, Mountman Portable Swamp Cooler, 10.6-Gal Tank, 120° Oscillation, 41" Water Cooler Fan for Indoor and Outdoor Patio, Porch, Yard. I purchased the unit because of the size of the tank, the fact that it doesn't need the window venting, making it easy to move room to room, the price is extremely competitive and the fact that Mountman provides a three-year warranty compared to other sellers with a one-year warranty. PLEASE READ ABOVE ALL THE SELLER'S DISCRIPTION OF THE QUALITIES OF THIS PORTABLE AC UNIT!!!! It has only been a few days, but my tenants are more than satisfied. This unit will enable them to stay cool. On the positive side, the house has two AC units and the one that covers the main house is still running. The unit that needs to be replaced covers the bedrooms. The new portable AC is in their bedroom, so other than adding water once or twice a day, everything is good. I am going to order at least one more so there will be no delay if any tenant loses an AC unit. Great inexpensive bridge unit the new unit is installed. Great investment even if you don't manage houses; I plan to use it in an Arizona room and the master bedroom so I can turn off the air to the AC unit cooling two other bedrooms. GREAT INVESTMENT!

Item is okay, but little heavy and little big for us. Sounds okay for low volume, little noise for high volume, new start to use has some plastic smell because it made by heavy duty plastic, but after blow out for a while before use, smell is away. Worked as a cooler and big fan, so far I grade it 3 to 4 star max.
