Negative ions can make the indoor dust, smoke, viruses and bacteria which are usually positively charged together, lose the ability to float freely in the air, and purify the air. 10 x 106ions/cm3 high concentrations of negative ions quickly cover the whole room, so you do not need to travel to enjoy the forest breathingNegative ions release small amount of negative ions which are beneficial to human health. Negative ions can not only effectively remove dust, sterilize and purify air. Negative ions also contribute to the synthesis and
