Nendo has designed an air purifier that uses centrifugal force to move water.
The centrifugal force is created by water revolving in a tank that then draws the water into an upper chamber where a fan vaporizes the water into the air.
Water that isn't vaporized is caught by the sides of the compartment and returns to the tank.
"Angling the form meant that the intake and outtake vents are a distance from each other, creating ideal air convection."
