Abstract:The thickness, basis weight, density, filtration resistance and filter efficiency of the random samples of a certain type of air filter paper were tested, and the data were analyzed by using SPSS19.0 software, and the influences of thickness, basis weight and density fluctuation on the measurements of filtration resistance and filter efficiency were investigated. Research results suggested that when the thickness of air filter paper was in 0.376~0.420 mm, there was no significant effect of the thickness on the measurements of both resistance and filter efficiency(α=0.05); when the basis weight was in 55.2~59.8 g/m2,it had a significant effect on resistance, and the linear regression equation between basis weight and resistance was Δp=2.641W， whose correlation coefficient R2 was 0.817,and there was no significant effect of basis weight on the measurement of filter efficiency(α=0.05); when the density was in 0.139~0.152 g/m3, there was no significant effect of the density on the measurements of both resistance and filter efficiency(α=0.05).
