Anion Generator DIY Ionizer Airborne Air Purifiers Negative Ion Module Cleaner Description: Working Principle: By using pulses and vibration of electric appliances, rise the original low voltage to DC high negative pressure. Making use of 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 time, therefore,after reacting with oxygen molecules in the air , negative ions will form. Features: 100% brand new and high quality Small size and high efficiency. This module is the finished module of transformer for small scientific production. Carbon fiber emission head, strong and durable, good stability. It is effective to remove the debris in the air and it's benefits for your health.
