Our Air Purifier use the ioniser technology<br>An air ioniser is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions, are particles with one or more extra electrons, conferring a net negative charge to the particle. Cations are positive ions missing one or more electrons, resulting in a net positive charge. Most commercial air purifiers are designed to generate negative ions. Air ionisers have been used to eliminate the occurrence of air-borne bacterial infections. <br>USB Ionic Air Purifier.
