Understanding Filtration Efficiency: PFE, BFE, and VFE

28/06/2021  Virtual filtration efficiency (VFE) is nearly identical to PFE and BFE. The biggest difference is that a specific virus is used in aerosol form instead of bacteria or particulates. VFE is exceptionally important in high-grade medical masks when blocking out viruses like COVID-19, influenza, and others is incredibly crucial.

Face masks against COVID-19: Standards, efficacy, testing ...

29/04/2021  Particle filtration efficiency (PFE) is a measure of how well the mask or respirator is able to capture particles in a specific size range. It is defined as the percentage of downstream particles over upstream particles. The fit of RPE is determined by the amount of leakage around the perimeter of the RPE. N95 masks belong to the general category of disposable particle

Explainer: Testing the Efficacy of Protective Face Masks

The Particle Filtration Efficiency (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.

Bacterial Viral Filtration Efficiency Tests Nelson Labs

The Viral Filtration Efficiency (VFE) test follows the same procedure as BFE, except the challenge organism used is the bacteriophage phiX174. Challenge controls are maintained at 1100-3300 plaque-forming units (PFU) with a mean particle size (MPS) of 3.0 ± 0.3 µm. This allows filtration efficiencies to be reported up to >99.9%.

How to Choose the Proper Masks for COVID 19?

25/03/2020  BFE is bacterial filtration efficiency and PFE is particle filtration efficiency. BFE is required for medical use mask. For corona virus, N95/KN95 or above is better choice. But the class A GB/T 32610 is also a choice for daily use, working place or home. If you go to the high risk place, you would better choose N95/KN95 and eyes protector.
