Review on Stanley ST-20F: 20-Inch Industrial High Velocity Floor Fan - Powerful Direct Drive, Sturdy All-Metal Construction, 3 Adjustable Speeds - Portable Cooling Solution by Jennifer Schmeisser

I personally like the sound of the fan when I sleep, so the fact that they sound like I'm on an airplane is a big plus for me. I understand that not everyone likes that white noise in their sleep. These fans move air like you wouldn't believe. They are absolute powerhouses when it comes to airflow. When it's hot, turn one of these on with the four buttons on the back of the fan (the first button when you look at the fan is for turning it off, the other three buttons for changing the speed. The manufacturer wasn't lying ). a bit when they say it runs at 4800 rpm on the highest setting. The absolute only thing found wrong with the fan is that at top speed on tiled floors you don't put anything on the floor (like something you put under a rug so it lays flat and doesn't skid). If this does not happen, the fan wanders around. I usually have to buy a new fan every time. summer, but I doubt it will be necessary this year. Almost forgotten. No matter what, make sure the fan is off.
