Mask Bacterial Filtration Efficiency (BFE) Detector ASTMF2299/ASTMF2299 03(2017), EN14683-2019,ASTMF2101-19

Product overview:

This PFE testing machine is used to measure the bacterial filtration efficiency (BFE) of medical face mask materials, employing a ratio of the upstream bacterial challenge to downstream residual concentration to determine filtration efficiency of medical face.

Standards:

ASTMF2299/ASTMF2299 03(2017), EN14683-2019,ASTMF2101-19.

Technical Parameters:

Technical characteristics of mask bacterial filtration efficiency (BFE) detector
