MS WORLD Double-head Air Negative Ion Anion Generator Ionizer Double-head Compact Air Negative Ion Anion Generator Ionizer Purifiers Cleaner Air Purifier  (Pack of 1)

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 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.
