This invention relates to a method of sterilizing air that contains airborne pathogenic agents or microorganisms such as spores, bacteria, viruses, yeasts and moulds The method consists in damaging and braking up the contaminant molecular structure by oxidation and ionization and chemical bond rupture. Through this process the microorganisms or the contaminants are inactivated through structural damages to the cellular membrane and/or the nucleus membrane and/or to the DNA structure. This is accomplished by creating through the air to be treated, various electronic current having a plurality of specific controlled average kinetic energies matching the desired chemical bonds to be affected and/or ruptured. The air interaction with such various currents, having specific energies, sufficient intensities and exposition time is accomplished through several stages to completely sterilize the air or gas.
