  • Mask Bacterial Filtration Efficiency (BFE) Testeris to determine the bacterial filtration efficiency (BFE) of medical face mask materials by employing a ratio of the upstream bacterial challenge to downstream residual concentration of the tested medical face mask materials. The control console adopts microcomputer control system to coordinate and control the work of aerosol generation system, transmission system, negative pressure cabinet and sampling system, and display the working status in real time. The whole measurement work is completed automatically.zfpTextile Testing Instruments, Testing Equipment Manufacturer
