Mask Virus Filtration Efficiency (VFE) Tester For Medical Protective Mask Materials
Face Mask Tester Executive Standard
Face Mask Tester Technology Advantage
Profile
The main performance indexes of the ZR-1000A mask virus filtration efficiency (VFE) detector conform to the YY/T1497-2016 detection method of Phi-X174 phage for the evaluation of virus filtration efficiency of medical protective mask materials . The method of double gas path simultaneous comparison sampling improves the accuracy of sampling, which is suitable for the measurement and verification departments, scientific research institutes, mask manufacturers and other relevant departments to detect the mask virus performance detect of filtration efficiency.

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.
