The fan is so good, that even people who have central air call it their “best purchase of the summer!!” Today, the white version is priced under $70, down from the regular price of $89.99. But act fast, as the weather heats up, we imagine the price of this fan will, too.

The Dreo smart fan doesn’t just blow a light breeze; it makes the entire room truly cold.

With four modes, 90-degree oscillation, and the ability to cool up to 25 feet per second, this fan is serious about temperature control. When one user’s central air died in the middle of a heatwave, they said this baby brought their office from a sweltering 92 degrees to a “comfortable, tolerable” 70 degrees — in less than two hours.

Another reviewer, who titled their review, “I thought all tower fans were made the same, I was wrong,” warns, “do not underestimate the power and necessity of this tower fan.”

“My sister owns this fan in another color, and when I went over to visit, I thought she bought another AC unit for her living room,” they said. ”...We had to turn it off midway since the living got too cold. I generally run very hot, and this little thing made me shiver.”
