Main effects proven with "Plasmacluster technology; Proven results with plasma cluster ion generating equipment in a test space equivalent to approximately 11.3 sq ft (6 to 10 tatami). If the ionic concentration is equal, it is believed to have the same effect. The effects of the plasma cluster may vary depending on the conditions of the place you use (temperature, humidity, width, shape, air conditioner, ventilation, etc.), product characteristics, and how you use it (ionic exhaust direction, driving mode, operating time, etc.). Disinfects floating mold bacteria, suppresses the effects of floating viruses, controls static electricity, pollen catching, 2-port USB car adapter, USB cable included.
