[0050] The special filter element 15 includes a high efficiency filter or an ESP high voltage electrostatic filter for removing particulate matter, bacteria and viruses as main pollutants, and an activated carbon filter for removing odor or harmful gases as main pollutants.

[0051] The high-efficiency filter mainly uses polytetrafluoroethylene material as the main filter medium. Polytetrafluoroethylene material is a high-efficiency and low-resistance material. The main filter medium is formed by a pleating process. The high-efficiency filter uses a plastic frame. After the plastic frame and the main filter medium are assembled, the joints are sealed using glue filling technology. The high-efficiency filter can remove particles with a diameter of 0.3μm or more, including bacteria, viruses, pollen and other particles. Its filtration effect is as high as about 99.9%. The purification device equipped with this high-efficiency filter can effectively cope with special environments such as moxibustion rooms, welding operation rooms, and wards.

[0052] ESP high-voltage electrostatic filters are driven by high-voltage power supply and can effectively remove pollutants such as particulate matter and bacteria. ESP high-voltage electrostatic filters can be repeatedly cleaned, dried and reused. Purification equipment equipped with ESP high-voltage electrostatic filters can effectively cope with sanitary places that need disinfection, such as moxibustion rooms, smoking rooms, hospitals, etc.

[0053] The activated carbon filter uses W-shaped filled granular activated carbon. The W-shaped can ensure a large cross-sectional area of ​​air passing through. The large cross-sectional area of ​​air can ensure that the activated carbon is in contact with the circulating air to the maximum extent during a single air circulation. Compared with the flat type, the W-shaped can greatly reduce the structural wind resistance of the activated carbon filter with the same cross-sectional area of ​​the air duct of the purification equipment. The air purification equipment is equipped with a special activated carbon filter to effectively remove odors and harmful gases. It can effectively deal with special places such as toilets and laboratories.
