Unlike Other Air Purifiers, The Ozone Generator Works Like This. Ozone Has Three Oxygen Atoms Instead Of The Two In The Air We Breathe, And The Unstable Extra Oxygen Atoms Can Detach.When It Encounters Bacteria And Harmful Chemicals (such As Formaldehyde, Benzene, Ammonia) It Immediately Produces An Oxidation Reaction, Which Results In Sterilization And Disinfection.
