Uthfy HY-40BI-51 swamp cooler, navy blue

Ok, I waited a few months to write the review. I have a Hessaire unit at work, and wanted something for the porch at home. This went on sale and I snagged it. As long as it’s dry (humidity below 30%, which it usually is here in southwest Texas), this thing is a god send! Cools a solid 25-30 degrees in dry hot days. Loses effectiveness over 100, but that’s any cooler. It moves a good amount of air on low, and moves a TON of air on high. The oscillation feature is nice, and being able to move the lovers up or down is a nice feature. Uses next to no power, as evaporative coolers tend to do, so very every efficient. On low it’s quiet enough to use and still talk around, on high you better be 10 feet away. Value for the money is great, beats a port cool that’s 4 times the price!

We got this for the heat wave here in Los Angeles and have been very happy with it. Our climate is generally pretty dry, so an evaporative cooler works well for what we needed. It definitely doesn't replace AC completely, but it makes the space cooler and much more comfortable. (You should find the best angle for the airflow of your room) The airflow is strong, the large water tank is convenient, and adding the ice packs helps when we want it a little cooler. I also like the oscillation because the air isn't just blowing in one direction. We've been using it during this stretch of 100-degree weather, and it has made a big difference for us. The wheels are very helpful to move it in different areas of our apartment and put it away when it finally gets colder, as it is very big. It's working great for us so far.

This swamp cooler works well and keeps my garage cool when I want to work there. I like the ability to switch the oscillating grill off and on. If you want to focus on working at your workbench or sit in a chair, turn the oscillation off. The push button and toggle switch controls make it easy to adjust fan speed, cooling and oscillation. The unit is on four castors which makes moving the unit easy. The top of the unit has a lid which provides access to the upper water reservoir and you can add frozen, plastic, blue freezer containers to cool the air more. The cons about this cooler are: 1) the connection pipe is poorly mounted on the cooler. It took a long time to figure out how to attach a hose and shutoff without leakage where the connection enters the cooler. It’s cheaply made and I was afraid it would break. 2) the water level indicator is a plastic float which continuously sticks in the tube it’s in. You have to open the access flap to feel what the water level is. 3) cleaning isn’t very easy. I kept this unit because it works well and is problematic returning. I’ve had it for a year and it’s still working and not leaking.

This Swamp Cooler is doing a great job on my back patio right now. It's 88 degrees outside here in Phoenix AZ and the swamp (or evaporative cooler) with the water running is keeping the patio right around 72/73 degrees. A long time ago, I lived in an old house here in Phoenix that only had a swamp cooler, and that unit had four sides, with each side having a wet pad to keep the house cool. So, when selecting an outdoor cooler I wanted be sure all sides pulling in hot air would have a wet pad that would cool all the air coming into the unit. Some of other cooler I looked at only had one pad in the back, with two sides vents that would pull in hot air, which in the end would make the cold air from the wet pad in the back warmer before it reached the motor that pushed the air out me - I'm so glad I found this unit! This unit looks to be well made, is sturdy, and rolls very easy even when filled with water. The motor is so strong that I don't even need to put it on high to cool off my 9x15 patio, the lowest setting works fine for me for now. Plus, the ice blocks have stayed frozen/cold all afternoon in the water, maybe 5 hours now and the water is still very cold. I used my new ECOFLOW solar power station to get an idea of the watts used by this swamp cooler .... Using the unit with the fan on low it pulled around 92w - on high it pulled around 164w. Using the swamp cooler on low with water pump running it pulled around 119w - on high it pulled around 187w. Now, the down side ... I'm having a problem with the hose connection leaking. I used some Plummer's tape to avoid this problem, but the connection site leaked anyway. I tried tightening the connection as much as I dared, as I'm afraid if I over-tighten it will destroy plastic plug connection in the unit's wall. This isn't a deal breaker for me as it is a very small leak and I just put a cup under to catch the dripping water, but it would be nice if I could get it to stop dripping. Maybe the seller will see this comment and help me figure out why the connection has a problem. Update 05/09/25 -- Wanted to add that their customer service is excellent! I needed some help with the swamp cooler and had some questions, and I found this company to be very considerate, understanding, and helpful to my needs. Also, right now it's exactly 100 degrees here in Phoenix AZ without the cooler, after turning on my new cooler the thermostat is now reading 83.5 degrees - AWESOME - and, it is still on the low setting. I'm over the moon with this company, customer service, and of course the swamp cooler. Thank you so much!

Works well in garage
