Description

Technical Field

[0001] This utility model relates to a filter element, specifically a high-efficiency filter element with an electrostatic adsorption layer. Background Technology

[0002] In the field of air filtration, as people's requirements for air quality continue to increase, traditional air filters are no longer able to meet the filtration needs of fine particulate matter and pollutants in modern environments. Many traditional filters mainly rely on physical interception to filter dust and particulate matter in the air, making it difficult to capture smaller fine particles, such as PM2.5, pollen, and bacteria, resulting in unsatisfactory purification effects.

[0003] Traditional filter cartridges typically employ only one filtration method (such as mechanical filtration or electrostatic filtration), failing to fully utilize the advantages of different filtration technologies, thus limiting the overall purification effect. Utility Model Content
