Loading and filtration characteristics of filtering facepieces / C.C. Chen, M. Lehtimäki and K. Willeke
Sumario: The present study investigated why respirators of the same category perform so differently. The degradation of colection efficiency by aerosol loading was also investigated. Some filtering facepieces of a higher performance category are made up of several layers of the same material used for a lower category filtering facepiece. This paper have investigated the cumulative effect of multiple filtration layers on pressure drop and filtration efficiency
