Compact Air Negative Ion Anion Generator Ionizer Purifiers Cleaner Car Home Tool Description: 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 A negative ion generator is a device that uses high voltage to ionize(electrically charge) air molecules. Negative ions, or anions, are particles with one or more for extra electrons, conferring a net negative charge to the particle. Air ionizers are used to eliminate the occurrence of air-borne bacterial infections and to reduce static electricity buildup in electronics.
