Abstract：The differences in humidity resistance between synthetic fiber filter materials and traditional wood pulp fiberfiltermaterialsaresystematically evaluated through staticanddynamic moistureabsorption tests，and the intrinsic mechanismunderlying thevariation inintakeresistanceof filtermaterialsunder high-humidityconditionsis investigated.Theresultsshow thatsynthetic fiber filtermaterialsaresignificantlysuperior to traditional wood pulp fiberfiltermaterialsintermsofdustholdingcapacity，initialfiltrationaccuracyandful-lifefiltrationperformance， whileexhibiting lower intakeresistanceandmorestablestructural characteristics.In bench testsunderhumid environments，synthetic fiber filterelementsdemonstrateexcelenthumidityresistancewithoutobviousstructural deformationor intakeresistancerise.Furtherdrum bench testresultsindicatethatsyntheticfiberfilter elementscan reduce the intake resistance by approximately 20% under high-humidity conditions，improving fuel economy by 1% . In addition，the 60，000km on-vehicle test verified that synthetic fiber filter elements achieve a remarkable fuel-saving effect，which confirms their performance advantages in practical applications.
