Cleangen is an indoor air purifier with unique design that is not found in any other conventional models. Consisting of a combination of smooth curves within, all the sides of the product are rounded, giving an overall smooth, cozy impression. Line typed protrusions are applied as a pattern to the sidewall of the product to naturally cover the inlet and outlet holes of the air purifier that could interfere with the design. A LED lighting is applied at the back of the Deco panel to indicate indoor air quality or operating status of the air purifier. As a playful detail, the LED light spreads softly along the rim as it changes the surrounding atmosphere, functioning as a mood light.
