Problems solved by technology

[0002] In recent years, with the development of industry and the prosperity of the economy, the corresponding air pollution has become more and more serious, and the use of air purification devices such as air purifiers and fresh air purifiers has become more and more popular. The filter screen is a high-efficiency air filter, that is, HEPA, such as the high-efficiency filter screen disclosed on August 7, 2018 with the publication number CN108371854A, which has an efficient sterilization effect and has an efficient adsorption capacity for PM2.5 and formaldehyde. However, due to HEPA will age, embrittle and fall off after a period of use, affecting its service life and effect
