Indoor air contains gases such as dust, bacteria, dust mites and formaldehyde. Air pollution reduces the air quality after natural convection ventilation in the room and increases the number of inhalable particles. Most of the existing air purifiers use negative ions after filtering dust to eliminate odors and harmful gases, or after multiple filtrations, activated carbon adsorption is used in the filter layer to remove odors, which often increases the wind resistance of air flow and energy consumption. This method cannot completely remove the toxic and harmful substances in the air, and cannot achieve satisfactory results.
