As the world trade field is expanding, international standard of air filter is urgently needed. At present,China is undergone its revising the national standards, therefore, the development of major air filterstandards between America and Europe is compared here. Diameter distribution of KCl aerosol used inASHRAE52.2 is similar with atmospheric dust, but research for test dust representing actual conditionis still needed. Concepts for electrostatic discharge between Europe and America are different, andclassification upon minimum life efficiency (MLE) is recommended. Final pressure drop in EN 779:2002should be lowered to reflect reality, and particle rebound phenomena should be included. Highefficiency particulate air filter (HEPA) should be installed upstream of tested filter. Measures to test dustholding capacity is recommended to be incorporated in ASHARE 52.2.
