Continuously improving filtration efficiency has always been a key focus of our company’s active exploration and research. In June 2024, at the production headquarters in Shijiazhuang, Hebei Province, the department’s research and development leaders led employees to conduct filtration testing on products produced using high-quality filter paper, continuously trying new production processes. Make sure that our air filters are in a leading position.

In terms of the size of the air filter production, the mold is required to be more accurate, with an error of less than 3 millimeters. In terms of filter paper selection, HV filter paper with high air permeability and high dust holding capacity is used. The rubber is made of high-quality natural rubber with good elasticity and aging resistance.
