The differences in humidity resistance between synthetic fiber filter materials and traditional wood pulp fiber filter materials are systematically evaluated through static and dynamic moisture absorption tests, and the intrinsic mechanism underlying the variation in intake resistance of filter materials under high-humidity conditions is investigated. The results show that synthetic fiber filter materials are significantly superior to traditional wood pulp fiber filter materials in terms of dust holding capacity, initial filtration accuracy and full-life filtration performance, while exhibiting lower intake resistance and more stable structural characteristics. In bench tests under humid environments, synthetic fiber filter elements demonstrate excellent humidity resistance without obvious structural deformation or intake resistance rise. Further drum bench test results indicate that synthetic fiber filter elements can reduce the intake resistance by approximately 20% under high-humidity conditions, improving fuel economy by 1%. In addition, the 60,000 km on-vehicle test verified that synthetic fiber filter elements achieve a remarkable fuel-saving effect, which confirms their performance advantages in practical applications.
