Purification Principle
① Primary filter: Filters out dust and particulates, such as hair and large particles. The filter is coated with a nano-silver ion layer that can kill bacteria and viruses.
② Plasma electric field: It generates a large number of plasma and negative ions. High-energy positive and negative ions (or charges) collide with bacteria and viruses, activating gases within the viral particles and producing various active free radicals. These free radicals decompose microorganisms, thereby killing bacteria and viruses.
③ Electrostatic precipitator: By generating and releasing a large number of negative ions from the negatively charged surface, suspended particles are caused to adhere to the surface.
