Mask bacterial filtration efficiency (BFE) tester is used to quickly and accurately detect Bacterial Filtration Efficiency (BFE) of various flat masks, 3D masks, and protective materials. This product is developed strictly following the Attachment B in YY0469-2011 "Medical Surgical Mask", Bacterial Filtration Efficiency (BFE) experimental method.

The product uses highly integrated design, intelligent control technology. It also conforms to ASTMF2100. ASTMF2101 and EN14683.

Application:

It is used to test the percentage of materials containing bacteria suspended particles at the specified flow rate. The dual gas path simultaneous comparison sampling method is used to improve the accuracy of sampling, which is suitable for the performance testing of bacterial filtration efficiency of medical surgical  by metrological inspection departments, scientific research institutes, medical mask manufacturers and other relevant departments.

FAQs

1. What is a BFE/VFE Tester?

It is a laboratory instrument used to evaluate the bacterial and viral filtration efficiency of protective masks and filtration materials.

2. What materials can be tested?

It is mainly used for medical masks, surgical masks, respirators, and other filtration materials.

3. What does BFE mean?

BFE stands for Bacterial Filtration Efficiency, indicating the percentage of bacteria prevented from passing through the test specimen.

4. What does VFE mean?

VFE stands for Viral Filtration Efficiency, indicating the percentage of virus-containing aerosol particles prevented from passing through the test specimen.

5. What are the benefits of the tester?

It provides controlled testing conditions and helps evaluate the filtration performance and quality of mask materials.
