According to Chinese National Standards (GB/T14295-2008,GB/T6165-2008), European standard(EN779:2012) and American standards(ASHRAE52.1-1992, ASHRAE52.2-2007),a testing device of filter materials' performance was set up. Using the filtration efficiency and resistance of acupuncture, meltblown and electret non-woven filter materials gathered from laboratory, purifying performance mathematical models were established and optimized with multiple regression analysis. With unified objective function, a comprehensive evaluation system was established. The research can provide important reference to choose and use non-woven filter materials to purify fine particles in ambient air.
