Description

Technical Field

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

[0002] An air purification filter is an air filtering device that aims to capture solid dust particles in both gas and solid phases, so that the air quality can be purified and improved. An air filter is a physical adsorption device that is reversible. For example, after long-term use of an air filter, dust will accumulate on the outside near the air inlet, which is difficult to clean and will affect subsequent filtration. If cleaned in time, most of the filtration functions can be restored. Currently, air purification filters are inconvenient to clean, so we consider how to facilitate the cleaning of accumulated impurity particles to increase their service life. In view of this, we propose an air purification filter. Utility Model Content
