The generated oxygen ion and active hydrogen combine with each other to generate hydroperoxy radicals. The hydroperoxy radicals surround and adsorb biological contaminants having a positive charge, and then bind to hydrogen in the protein structure on the surface of the contaminants. It reacts to destroy the surface structure.

In addition, active hydrogen combines with OH-radicals to neutralize active oxygen harmful to the human body in the form of water molecules.

Accordingly, since the air passing through the ionizer 440 contains hydroperoxy radicals in a state in which active hydrogen and oxygen ions are combined, various biological contaminants contained in the air or adsorbed to various articles by these And it can destroy and remove or neutralize active oxygen.
