The basic structure of the filter in the air suction filter

Air quality is a vital part of people's lives, which directly affects people's health and quality of life. In recent years, with the acceleration of industrialization and the increase in the number of cars, air pollution has become increasingly serious. In order to solve this problem, air adsorption filters have become a common air purification equipment. As the core component of air adsorption filters, filter nets play an important role in filtering particulate matter.

The material of the filter net is a key factor affecting its filtration efficiency and service life. At present, commonly used filter net materials include polyester fiber, glass fiber and synthetic fiber. These materials have good filtration effects and long service life. Among them, polyester fiber has high adsorption performance and durability, which is suitable for general air filtration needs. Glass fiber has higher filtration efficiency and longer service life, which is suitable for high-efficiency air filtration needs. In addition, synthetic fiber has good high temperature resistance and can maintain a stable filtration effect even in high temperature environments.

In addition to the choice of materials, the structure of the filter net also has an important influence on its filtration efficiency. The common filter net structures on the market currently include single-layer nets, multi-layer nets and composite nets. The single-layer net is composed of a layer of fiber net, which has the advantage of low air resistance and is suitable for occasions with high air flow requirements. However, its filtration efficiency is relatively low and its ability to intercept particulate matter is limited. The multi-layer net is composed of multiple layers of fiber nets, and the pore size of each layer of net gradually decreases. This structure can improve the filtration efficiency and increase the retention capacity of particles. The composite net is composed of fiber nets of different materials, which has higher filtration efficiency and longer service life.

The pore size of the filter is also an important factor affecting its filtration effect. The pore size is usually expressed in mesh and micron. The mesh number indicates the number of lines per inch, for example, a 100-mesh filter means that there are 100 pores per inch. The micron indicates the size of the pore, for example, a 10-micron filter means that the pore size is 10 microns. According to the size range of particles, the appropriate filter pore size can be selected. Large particles usually require larger pores to be retained, while fine particles require smaller pores. Therefore, it is very important to choose the appropriate filter pore size according to actual needs and application scenarios.
