air filterIt refers to an air filtration device, generally used for dust prevention, anti-virus, purification, etc. in indoor spaces. Air filters can be divided into primary-efficiency filters, medium-efficiency filters, high-efficiency filters and ultra-high-efficiency filters according to their effectiveness.
Primary air filters are mainly suitable for primary filtration in air-conditioning and ventilation systems and pre-filtration of local high-efficiency filtration devices, such as air-conditioning filters. Medium-efficiency air filters can be used in homes, office buildings, schools, cars, rail transit and other places that do not have strict requirements for air purification, such as air-conditioning filters with high filtration efficiency and some air purifiers. High-efficiency and ultra-high-efficiency air filters are suitable for air filtration that requires a high degree of air purification. They can be used in aerospace, aviation and other fields, as well as dust-free purification workshops in pharmaceutical, bioengineering and other industries. Air filters can be divided into air conditioning filters, air purifiers, rail transitautomobileship air filters, clean room air purification equipment, etc. according to their application fields.
Air filters can be widely used in household and commercial appliances, automobiles, rail transit, aerospace, aviation, electronics, pharmaceuticals, bioengineering and other fields. In recent years, with the rapid development of the above industries, the demand for air filters has also increased. Thanks to the rapid development of downstream application industries and the rapid growth of residents' disposable income, China's air filter market continues to expand. Air filters are used in a wide range of industries, and professional operation is the main feature of the industry. There are many companies involved in the air filter industry and competition is fierce, but there are few companies that have formed large-scale operations.
