This patent covers a novel air purifier technology designed to significantly improve indoor air quality. The system consists of multiple chambers, each equipped with air filter assemblies. The unique features include a separator between fine mesh filter fabrics, liquid tanks for water, alkaline solution, or acidic solution, ultraviolet (UV) light sources, and an auto-cleaning mechanism. The technology effectively traps and neutralizes airborne contaminants, including viruses, bacteria, allergens, and fine particles, by combining filtration with UV sterilization. In addition, it features an ionization function in the dry mode, further enhancing its air purification capabilities.
