FAQ

1. What is a mask filter efficiency tester?​

It is laboratory equipment that measures how well a mask's filter media blocks particles and bacteria. Testers pass a controlled aerosol through a mask sample and compare the particle counts before and after filtration, so the result is expressed as filtration efficiency as a percentage.

2. What does it measure: BFE, PFE or VFE?​

A mask filter efficiency tester typically measures bacterial filtration efficiency (BFE) and particulate filtration efficiency (PFE). BFE uses a bacterial aerosol such as Staphylococcus aureus, while PFE uses a polydisperse particle aerosol at a defined size, typically around 0.3 μm. Viral filtration efficiency (VFE) can be measured with additional configurations that use a viral aerosol.

3. Which standards can a mask filter efficiency tester test to?​

Common standards are EN 14683 (BFE), ASTM F2100 (BFE and PFE), GB/T 32610 and GB 2626. Before buying a mask filter efficiency tester, check that its aerosol generation, flow rate, sampler stages and pressure control match the standard you need to report.

4. How do I choose the right mask filter efficiency tester?​

Match the tester to your target standard first, then compare sampling flow (28.3 L/min is typical), aerosol particle size control (3.0 ± 0.3 μm), chamber sealing and negative pressure range, HEPA filter rating, and whether dual-route A/B sampling lets you run control and test samples at the same time.

5. How often does a mask filter efficiency tester need calibration?​

Calibrate flow, pressure and particle counting at least annually, and verify performance with a positive control at each test run (for example, 2200 ± 500 CFU). Use certified reference materials and record the results, so your reports stay traceable and comparable over time.
