Customer Reviews
Customer Review: “I waited until the end of summer to leave my review, so I could have an idea of how this evaporative cooler would hold up after months of use. I live in So Cal, and specifically bought this for work. I work in a large outdoor booth without any kind of cooling. After several summers of suffering from the heat, this unit has been a game-changer.”
Customer Review: “My AC for my home went out and needs to be replaced. Even when it worked it only worked on the main level and not in the basement. I started out looking for AC units that do not need to be vented for my basement and purchased some 2 in 1 breezewell units. The first one I got worked pretty well. When that one died, I upgraded to this Hessaire—and it’s been even better.”

Customer Reviews
Customer Review: “We recently moved into a house in the mountains of Colorado, and most homes up here do not have a/c, including our house. With the windows closed all day while at work, the temp was getting up to 75-77 during the later afternoon hours (outside temps have been about 80, but lots of direct sunlight on the house). This cooler brought indoor temps down to a comfortable 68–70°F.”
Customer Review: “This is such a handy device. Helps with a/c costs because it will cool the room I’m in and I don’t have to run the house a/c high. It’s portable and easy to seasonally clean. When my friend’s a/c went out in her home I was able to put this in my car and bring her some relief. Definitely worth the $.”

Frequently Asked Questions
Q: Do evaporative coolers work in humid climates?
A: Evaporative coolers are most effective in dry, low-humidity environments. In humid areas, they provide minimal cooling and may increase moisture levels uncomfortably.
Q: How often do I need to refill the water tank?
A: It depends on the model and usage, but most portable coolers require refilling every 4–8 hours during peak operation. Larger tanks reduce refill frequency.
Q: Can I use an evaporative cooler indoors?
A: Yes, but only with proper ventilation. Evaporative coolers add moisture to the air, so windows or vents should be open to allow humid air to escape.
Q: Are evaporative coolers energy efficient?
A: Absolutely. They use significantly less electricity than air conditioners—often just 25–50% of the energy—making them an eco-friendly cooling solution.
Q: Do I need to add ice for better cooling?
A: Adding ice or ice packs can enhance cooling performance, especially on extremely hot days. Many models include dedicated ice compartments for this purpose.
