Green Circle / Air purifier

Green Circle
Green Circle

Clean air is without doubt a necessity for human life. Air purifier is then required by urban people. However, current devices using filters suffer from jamming every once in a while. A similar problem also occurs on vacuum cleaners, which later been improved with cyclone technology and can also be adopted on air cleaners.
The outcome is called Green Circle. Inside the Circle, dusts are collected with cyclones and fall in the pot, in which grasses are grown and grab the dusts with its roots. Clean air come out from above and flick through the grasses. Green Circle brings you a refreshing breeze.
