The BFE test is performed to determine the filtration efficiency of test articles by comparing
the bacterial control counts upstream of the test article to the bacterial counts downstream. A suspension
of Staphylococcus aureus was aerosolized using a nebulizer and delivered to the test article at a constant
flow rate and fixed air pressure. The challenge delivery was maintained at 1.7 - 2.7 x 10^ colony forming
units (CFU) with a mean particle size (MPS) of 3.0 ± 0.3 pm. The aerosols were drawn through a six-
stage, viable particle, Andersen sampler for collection. This test method complies with ASTM F2101-14,
EN 14683:2014, Annex B, and AS4381:2015.

All test method acceptance criteria were met. Testing was performed in compliance with US FDA good
manufacturing practice (GMP) regulations 21 CFR Parts 210, 211 and 820
