1Pc Anion Air Purifier Ionizer Negative Ion Generator Module Vitamin Cleaner Car Working Principle: By using pulses and vibration of electric appliances, rise the original low voltage to for DC high negative pressure. Making use of for DC high voltage of carbon brush tip to produce high corona, emitting large amounts of electronic at a high speed. Electronics can not remain in the air for a long for time, therefore,after reacting with oxygen molecules in the air , negative ions will form. Features: brand new and high quality It can improve air quality, clean air, the human body has a very important influence. Daily amount of negative ions breathing, can strengthen brain function and mental activity. Lower blood pressure, strengthen heart function, increased lung function and so on.
