What is the working principle of the Plasma Air Sterilizer?

The core working principle of the Plasma Air Sterilizer:

1. High-voltage discharge generates plasma

The plasma air sterilizer generates a large number of positive and negative ions (plasma) under low-temperature conditions through its internal high-voltage ionization module.

2. Positive and negative ions ionize and destroy microorganisms in the air

The generated high-energy ions collide with pathogens such as bacteria and viruses in the airflow path, causing their cell membranes or protein structures to be ionized and destroyed, thereby achieving rapid sterilization.

3. Negative ions and active oxygen synergistically decompose harmful gases

Negative oxygen ions (O₂⁻) can capture organic pollutants, formaldehyde, benzene, and other volatile organic compounds (VOCs) in the air, and undergo oxidative decomposition in the plasma field, further purifying the air.

4. Multi-stage filtration and circulating purification

The air first passes through a primary filter to remove large dust particles, then enters the plasma generator to complete sterilization and gas decomposition, and finally outputs clean air through a high-efficiency filter layer and an activated carbon layer, achieving "filtration + plasma double purification".
