Traditional air cleaner designs (BOX type) are insufficient for making good use of space and can be visually boring, but this unit has a soft minimalist design after reinterpreting a smooth cylinder. This design enables the unit to function as a small interior décor, and the vertical design allows the unit to be efficiently located in narrow spaces as well. This unit is to be launched in both general and WiFi models. The former is to maximize economic feasibility by utilizing essential functions while the latter allows users to check air quality and control the unit from outside, designed for the network-based lifestyle trend.
