[0002] The air filter element realizes air purification through physical filtration and chemical adsorption mechanisms, and its core structure is composed of a composite origami layer and an activated carbon layer. The composite origami layer uses high-efficiency filter material and can accurately intercept suspended particulate matter in the air, including dust, pollen, PM2.5 and other pollutants; the activated carbon layer effectively adsorbs volatile organic compounds (VOCs), odors, formaldehyde, benzene and other harmful gases through its porous structure and surface chemical properties.
