Is the negative ion produced by Zhongke Yidong negative oxygen ion machine the same as that produced by plants?
At present, the technology of artificial generation of small particle negative oxygen ions by Zhongke Yidong is very mature, which can generate ecological small particle negative ions equivalent to nature. It can cover 4-5 meters without blowing by a fan, forming a negative ion forest bath environment indoors, which is basically no different from the negative oxygen ions produced by plants.
