EcoGecko 75020 Classic Water Based Air Purifier Revitalizer/Freshener - Black
The working theory of the Air Revitalizer is Siphon and Centrifugal force. It siphons the mixture of essential oil and water into the suction tube and then with high speed rotation, rotates the mixture centrifugally then spreads onto the container and forms a water layer to eliminate dusts and germs in the air. Then takes the fresh fragrant air back to the room after purifying the dust and bacteria through the water layer.
