TEST REPORT
Report unit Bacterial Filtration Efficiency = %
Report unit Number of Bacteria = cfu/mL
A specimen of the mask material is clamped between a impactor and an aerosol chamber. An aerosol of Staphylococcus aureus is introduced
into the aerosol chamber and drawn through the mask material and the impactor under vacuum. The bacterial filtration efficiency of the mask is
given by the number of colony forming units passing through the medical face mask material expressed as a percentage of the number of
colony forming units present in the challenge aerosol.
