[0002] The positive and negative ions generated by the plasma generator simultaneously neutralize the positive and negative charges in the air, which releases a huge amount of energy, causing changes in the structure of the surrounding bacteria or energy conversion, thereby killing the bacteria and achieving its sterilization effect. Since the number of negative ions is greater than the number of positive ions, the excess negative ions still float in the air, which can eliminate smoke, dust, odor, improve air quality, and promote human health.
