PFE TEST

While BFE and VFE tests are designed to find out how well a mask filters biological aerosols, the PFE test measures how well it filters airborne particles such as pollen or dust. This is done by filtering particles about 0.1 micron in size.

The higher the PFE of a mask, the more particles it filters. If it can filter particles about 0.1 micron wide, it is likely to be able to filter droplets that are typically much larger, and which might contain SARS-CoV-2.

For example, a mask with a PFE of 95 per cent – meeting the requirements for medical and surgical masks (ASTM F2100-19 Level 1 barrier protection) – blocks 95 per cent of particles it is exposed to.
