VFE TEST
This test determines how well a mask filters virus-containing droplets about 3 microns in size. It is similar to BFE in that it uses droplets of similar size, but uses a different challenge organism (bacteriophage instead of bacteria).
The higher the VFE, the more effective a mask is as a barrier against viruses, including coronaviruses. A mask with a VFE of 95 per cent, for example, blocks 95 per cent of virus-containing droplets it is exposed to.
