Air purifier filter system science to control the spread of bacteria in the air

　　In the overall structure of the air purifier, the filter system plays a huge role. Generally speaking, the filter layer of a conventional air purifier mainly has the following five layers, which are:

　　1. Coarse-effect filter: it keeps the larger particles in the air and can be washed and used repeatedly.

　　2. Electrostatic dust collector: Collect suspended small particles, such as smoke, pollen, dust mites and bacteria.

　　3. Activated carbon: It absorbs gaseous organic pollutants caused by peculiar smell in the air or decoration. The service life of medical air purifiers is generally three to six months and needs to be replaced regularly.

　　4. High-efficiency filter: filter a small amount of remaining suspended small particles, the service life is generally 3 to 6 months, and it needs to be replaced regularly.

　　5. Photocatalytic reactor: filter bacteria, dust mites, peculiar smell and gaseous pollutants not filtered by other layers to react into other non-hazardous substances, reducing the original harmful substances.

　　It is precisely because of its structural advantages that air purifiers have received more and more attention and welcome from the market. Nanchang Yangfan Environmental Protection Equipment Co., Ltd. is an air purification and disinfection device company specializing in the design, development and sales of air purifiers. The air purifier produced is specially designed for the coexistence of humans and machines. It can be disinfected in the presence of people, and there will be no peculiar smell during the disinfection process. At the same time, it also avoids any radiation. The ultraviolet rays are completely sealed during the operation of the equipment. Inside the machine, the concentration of ozone in the air during work is ≤0.1mg/m?, which is far lower than the national standard of 0.15mg/m?.
