Daan, which means "unit" or "column" in Korean, is an air purifier for home use. A single unit covers around 15m2, about the size of a small room. Users can improve the performance to cover an area up to 30m2 and 45m2 by stacking the product, making it an effective air purifier for a living room. The product separates into three units that can be easily carried between rooms and slipped onto independent stands. Fabric and aluminum give the Daan a pleasing appearance that allows it to fit into the interior décor of any living space. A mood lighting function that creates a soft atmosphere further enhances its decorative aspects.
