Management Number: 206052-00572 [Description] Monitors the condition of the room with three sensors: highly sensitive dust, odor, and brightness. The highly sensitive dust sensor detects not only large particles such as pollen, but also finer particles. In addition, it identifies the concentration (approximate) of fine particles such as PM2.5 using our unique algorithm and indicates it with the number of lamps, making it easy to understand. When the concentration is high, the airflow is increased to collect dust. It releases a large amount of high-density plasma cluster to a wide space, keeping the space comfortable. The approximate applicable floor area for air purification is 107m² (65 tatami mats). In addition to the high-performance dust collection function, it releases a large amount of high-density plasma cluster, keeping a wide space comfortable.
