Filtration Test Standard Center for Filtration Researchsp.infoViral Filtration Efficiency (VFE) The VFE is not recognized as a standard test method but has been adapted by Nelson Laboratories (https://nelsonlabs) from the ASTM F2101 method.VFE test follows the same procedure as BFE,except the challenge organism is the bacteriophage phiX174 and Escherichia coli bacteria as the host.Vitalograph Cross Contamination Report for Bacterial

Vitalograph BVFs were then sent to Nelson Labs to be tested for BFE (see Appendix 2) and VFE (see Appendix 3).The testing was completed on 3 BVFs chosen at random from a batch.The lowest results attained for BFE and VFE was then used to calculate the BVFs’ ability in preventing bacterial and viral cross-contamination.

VFE Viral Filtration Efficiency Test - EUROLABsp.infoThe Viral Filtration Efficiency (VFE) test follows the same procedure as BFE,except that the used organism of difficulty is bacteriophase phiX174.Difficulty controls are maintained in 3.0-0.3 plaque-forming units (PFU) with an average particle size (MPS) of 1100 ± 3300 µm.This allows filtration efficiencies to be reported up to> 99,9%.Estimated Reading Time 3 mins99% Effective Face Mask with Filter Test Results - KandyMask
