Description

Technical Field

[0001] The present application relates to the field of air environmental protection appliances, and specifically to a filter structure for air environmental protection equipment. Background Art

[0002] Air is one of the basic conditions for human survival, but with the rapid development of industrialization, urbanization and transportation, air pollution has become increasingly prominent. Air pollution has brought serious impacts on human health, ecosystems and climate change.

[0003] Air environmental protection refers to a series of actions and measures to protect and improve the quality of the atmospheric environment, reduce the emission of atmospheric pollutants, and maintain human health and ecological balance. Air environmental protection equipment is equipment used to purify, monitor and control air pollutants. These devices can help reduce or eliminate pollutants in the atmosphere and protect human health and environmental quality. Filter structures are usually used in air environmental protection equipment to filter fine particles such as dust in the air.
