The Air garden is a premium air purifier designed with a natural motif beyond simple functions. Air purifiers are products that are used 24 hours a day and breathe together in everyday life. We designed air purifiers to go beyond functional emphasis and to provide comfortable stability without creating a sense of incompatibility in space. The Air garden is designed with a natural motif. It implements the perfect function through the combination of a cylindrical wooden pillar, an inlet resembling a root, and an outlet resembling a tree rings. The formatively honest cylindrical volume expresses natural objects in space through a combination of two colors: dots and lines, horizontal and vertical. The Air garden contains the value of making nature and the environment sustainable as well as the appearance through the use of eco-friendly resin and a minimal form of common parts structure.
