Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to an air precision filter. Background Art

[0002] Air quality is an important indicator in daily meteorological monitoring. Its quality can directly reflect the degree of air pollution in a region. Severe air pollution can cause serious damage to the human respiratory system and even the nervous system. Air quality control is generally achieved through two basic ways, namely controlling the source of pollution and using equipment or planting greenery to purify the air. Indoors, purification equipment is more often used to filter and purify the air, thereby improving indoor air quality.

[0003] Most of the existing precision air filters need to be completely disassembled before the filter element can be replaced, which is very inconvenient. At the same time, the filtration process is short and the filtration method is single, and there is still room for improvement in the air purification and filtration effect.

[0004] In order to solve the above problems, we have made improvements and proposed an air precision filter. Utility Model Content
