Outline of Final Research Achievements

Present work studied the testing methods of air filters for PM2.5 and the consistency of collection efficiency data for nanoparticles. As a result, it was found that the filter life can be well predicted by using polydispersed particles which have the same size distribution as that of atmospheric aerosols when they are dispersed completely to primary particles by using the superjet mill. Moreover, we found that the log-log plot of particle penetration agaist Peclet number gives a good criteria for testing the consistency of pentration data.
