Generation technology of ecological negative ions?

Ecological grade literally means original ecology, which can be equated with negative ions in nature, but actually refers to negative ions with small particle size. The negative ions in Yuan Ye forest are basically of ecological grade, so the synthesis cannot be guaranteed. In recent years, negative ions have been relatively hot, and various related products have emerged in an endless stream with uneven quality. In fact, this mainly depends on the generation technology. For example, some negative ions need to be blown out by a fan to float far away. This is obviously not a small particle. However, the negative ions generated by the VIIYI negative ion air purifier with the technology of ecological negative ion generation chip and nano fullerene negative ion releaser can float to a long distance without any external force, with high activity and long migration distance. This is the negative ion with small particle size, which has great advantages when air pollution is gradually normalized.
