1Pc Anion Air Purifier Ionizer Negative Ion Generator Module for Car Working Principle: Uses electrical pulses and vibration to increase low voltage to high DC negative pressure. Utilizes high DC voltage at the carbon brush tip to produce a high corona, emitting a large number of electrons at high speed. Electrons react with oxygen molecules in the air to form negative ions.
