When air passes through the DBD module of the device, it produces cold plasma.
Cold plasma is a highly reactive and unstable mixture of positive and negative ions. They diffuse into the air and react with harmful elements to break the chemical bonds of pollutants and inactivate cell membranes of bacteria, viruses, etc. eventually produce harmless products H20 and CO2.
Cold plasma technology is used in sterilization of medical fields. It has no secondary pollution and is safe for people, pets and environment.
