This megasonic cleaning device from Coway was quite a hit, and now the company introduced yet another interesting looking appliance – Daan air purifier. It looks like a small drum or a speaker, but Daan, which means unit or column in Korean, is the home air purifier. A single unit covers a 15 m² room, which is 161 sq. ft. You will get better performance, covering an area between 30 m² and 45 m² by stacking Daan. The air purifier separates into 3 units that can be easily carried between rooms and slipped onto independent stands. Made of fabric and aluminum with a mood lighting function, Daan fits into the interior decor of any living space, creating a soft atmosphere for your home.
