As air passes through the ionization tubes, millions of negatively and positively charged ions are generated – just like nature. Massive ions disperse into the air or the occupied space through the duct, proactively destroying airborne contaminants where damage heath of occupants. In terms of eliminating airborne pollutants (e.g. Virus and bacteria, VOCs (Volatile Organic Compounds), odors, and particulate matter), plasma air purification is characterized by safety, low maintenance, simple installation, and high efficiency.
