The Bacterial Filtration Efficiency (BFE) test is done on filtration materials, fabrics, covers and devices designed to provide protection. It is a measure of the resistance of a material to the penetration of bacteria. BFE or Bacterial Filtration Efficiency is a measure of the resistance of a material to bacteria penetration. The results are reported as percent productivity and are related to the fabric's ability to resist bacterial penetration. Higher numbers in this test indicate better barrier efficiency. Bacterial Filtration Efficiency tester from qinsun-lab is mainly used for the performance testing of respiratory protection products, disposable masks, filter medium, the security testing which is suitable for such products, basic filtering performance evaluation and guidance for the development of new products. Our Mask filter performance tester i...
