What are the differences between plasma and negative ions？

1.Negative ion generator: The negative ions are negatively charged particles. The oxygen molecules in the negatively charged air combine with tiny water molecules to generate negative ions. The generator uses high-voltage corona to increase the negative ions in the air.
2.Plasma generator: The main working principle of the plasma generator is to raise the low voltage to positive high voltage and negative high voltage through the booster circuit, and use positive and negative high voltage to ionize air (mainly oxygen) to produce a large number of positive ions and negative ions. The number of negative ions is greater than the number of positive ions (the number of negative ions is about 1.5 times the number of positive ions).
3.The positive and negative ions produced at the same time produce huge energy release when they neutralize the positive and negative charges in the air, which leads to changes in the structure of the surrounding bacteria or energy conversion, thereby causing the death of the bacteria and achieving its sterilization effect. Because the number of negative ions is greater than the number of positive ions, the excess negative ions are still floating in the air, which can achieve smoke elimination, dust removal, elimination of odors, and improvement of air quality to promote human health.

Advantages compared with negative ion generator:
Generally, the negative ion generator uses the negative high voltage generated by the ionized air to produce a large number of negative ions. The negative ions and the small amount of positive ions naturally existing in the natural air neutralize the positive and negative charges. A certain amount of energy is released instantly, which effectively leads to the changes in the structure of the surrounding bacteria or the conversion of energy cause the death of the bacteria and achieve the effect of sterilization. However, the number of positive ions naturally present in the air in nature is quite small, so its sterilization effect is very small. Therefore, the sterilization effect of the positive and negative ion generator (plasma generator) far exceeds that of the negative ion generator.
