Features: A negative ions generators is device that uses high voltages to ionizer(electrically charge). Negative ions, or anions, are particles with one or more for conferring a net negative charge to the particle. Air ionizers are used to eliminate the occurrence reduces electricity buildup in electronics. This product is made from high-quality materials, exquisite workmanship, very good quality and long service life. This product is very easy to install, no additional tools are needed, and the installation process is very convenient.
