Wherein the cylindrical filter element 11 can be conveniently installed through the cylindrical frame 10.

Referring to fig. 3, the cylindrical filter element 11 preferably includes, in order from the outside to the inside, a filter web 14, an activated carbon layer 15, a nano-adsorption layer 16, and a HEPA filter layer 17.

The filter fleece 14 is a cotton filter material for filtering air, liquid or solid particles. It has adsorption, filtration and protection functions and is widely used in various fields. The following are some common problems and applications with filter cotton: filter cottons are generally made of cotton fibers, which have good adsorptivity and filtering properties. In addition to cotton fibers, other materials such as activated carbon, bentonite, etc. are sometimes added to enhance the filtering effect.

Among them, the activated carbon layer 15 is a common filter material, and is widely used in purification treatment of air and water. The active carbon is a porous adsorption material, has highly developed internal surface area, and can effectively adsorb and remove organic pollutants, peculiar smell, harmful gases and the like in air or water. Activated carbon is a specially treated carbon material, and is generally carbonized from natural substances (such as wood, coconut shells, coal, etc.). It features extremely high porosity and surface area, and provides good adsorption performance. The highly porous structure of the activated carbon material enables it to adsorb gases and substances dissolved in water. Through the actions of physical adsorption and chemical adsorption, the activated carbon can adsorb and remove organic compounds, peculiar smell substances, harmful gases and the like in air or water.

The nano adsorption layer 16, nano adsorption dust removal, is a technology for adsorbing and removing tiny particles in air by using nano materials. The nano adsorption dust removing technology adopts nano materials with high surface area and adsorption capacity, and adsorbs and removes particles in the air, including dust, pollen, bacteria, viruses and the like through physical or chemical adsorption. The nano adsorption dust removal technology utilizes the special properties of nano materials, such as high specific surface area, porous structure and specific surface activity, to adsorb tiny particles in air. The nanoparticles may adsorb particulate matter by physical adsorption, and may adsorb and convert harmful gases by chemical reaction. Compared with the traditional filtering method, the nano adsorption dust removal technology has the following advantages: fine particles such as PM2.5, PM0.1 and the like can be effectively removed; the adsorption capacity is high, and harmful gases and volatile organic compounds in the air can be removed; the nano material has larger specific surface area and porous structure, and provides more adsorption positions; the nano adsorption material can be regenerated, so that the service life is prolonged.

Among them, HEPA filter layer 17, HEPA (High Efficiency Particulate Air) filtration is a high efficiency particulate air filtration technology for removing fine particulate matter from air. The filter is suitable for the fields of indoor air purification, industrial pollutant control, medical facilities and the like, and can effectively filter, capture and fix particulate matters in the air, including dust, pollen, bacteria, viruses and the like. The HEPA filter is made of net-shaped fiber materials, and can effectively capture particulate matters in the air. The fiber cloth layer of the HEPA filter has a highly developed internal structure, so that the filter has a large surface area and high porosity. Fine particulate matter is effectively filtered out by being blocked and captured by the cloth layer as it passes through the filter. According to international standards, the HEPA filter has a minimum filtration efficiency of 99.97% for 0.3 micron particulate matter. However, some high efficiency HEPA filters can also achieve higher filtration efficiencies, such as 99.99% and even higher. HEPA filters have higher filtration efficiency and less particulate matter capturing capacity than conventional filters. While conventional filters may only be capable of filtering larger particulate matter, HEPA filters may be effective in filtering a large portion of fine particulate matter, including PM2.5, viruses, etc.

Through the cooperation of above each filter layer, can effectively purify the air, promote air purification effect.
