I use this fan every day as a window fan and circulation fan in my bedroom. My family grew up listening to box fans, so I've always thought fans were the same - noisy, ugly, not particularly efficient, and prone to tipping over. Air circulation pumps are different from box fans. While the box fan stirs up the air in the immediate vicinity of the fan, the circulation pump pushes the column of air in a specific direction. Circulation pumps are much more efficient at creating wind in a room or pushing air through a window. Forced air fans typically have a circular duct around the fan blades, tapering towards the front of the unit, and a spiral grille to balance airflow. Torque of the airflow exiting the device. Compared to a box fan, this circulator is compact, easy to carry and store, just place it on a table or windowsill and point it in the right direction, it consumes around 10W at 50% power compared to up to 90W for a box fan at low power it moves many times more air at high speed and creates a light breeze in the room at the lowest speed. I think there are other circulating fans cheaper to buy, the key to this one is the stepless speed control - it can be completely silent on the lowest setting, it stays relatively quiet up to about 50%, making a vehicle silent with the window open maximum setting. Alchemy or Vfan vintage style controller and brushless motor to be practical and beautiful at the same time
