Product Usage

Applications of bacterial filtration efficiency tester:
Bacterial filtration efficiency (BFE) testers are performed on filtration materials and equipment designed to prevent biological aerosols, such as masks, surgical gowns, hats and air filters. G299 automated filter tester is suitable for all kinds of masks, meltblown cloth protective clothing / gloves etc.

 



Bacterial filtration efficiency tester test principle:
A certain concentration of bacterial aerosol accurs at upstream of the mask, entering the aerosol chamber and mix, the bacterial aerosol enters into two parallel gas path sampling system. One adds test sample to the sampler and other one does not add samples as positive quality control (total bacterial count). The ratio between the positive quality control value and the sample test value is the filtration efficiency.




Applicable Standards


  • ASTM F2100 standard specification for performance of materials used in medical face masks

  • EN 14683 standard that medical face masks in Europe are required to comply with

  • ASTM F2101 standard test method for evaluating bacterial filtration efficiency (BFE) of medical mask materials using Staphylococcus aureus biological aerosol

  • YY0469-2011 Technical requirements for surgical mask

  • YY/T 0969-2013 Single-use medical face mask
