Nendo, a Japanese design firm created an air purifier ‘Arobo’ that uses the spherical shape and the centrifugal force created by water for a more effective use.
According to Nendo, “an air purifier that uses the centrifugal force created by water revolving in a tank to draw the water into the upper compartment, from where a fan vaporizes it into the air. Water that is not vaporized is caught by the sides of the compartment and returns to the tank.
Research into the most efficient form for the water’s circulation determined the purifier’s spherical shape.”
