The main effect demonstrated by "Plasmacluster technology". This is a proven result using plasmacluster ion generating equipment in a test space equivalent to about 10 tatami mats. It is believed that if the ion concentration is equal to the same effect. The effectiveness of the plasma cluster depends on the situation where it is used (temperature, humidity, width, shape, air conditioning, ventilation, etc.), product characteristics, and how to use (ion blow direction, operating mode, operating time, etc.). Kills floating mold and mildew, suppresses airborne viruses, suppresses static electricity, pollen catch, 2-port USB car adapter, USB cable included
