Development of a procedure for measuring the effectiveness of filters for collecting nanoparticles

In this study, the performance of one model of N95 NIOSH approved filtering face-piece respirator (FFR) was characterized against poly-dispersed and mono-dispersed NPs using two different experimental set-ups. Using the poly-dispersed aerosols test (PAT) method, the results demonstrated that the initial particle penetration was significantly enhanced with the increased airflows and a shift toward smaller particle size was observed for the most penetrating particle.
