Detail:

BFE Nebulizer refers to a nebulizer specifically for Bacterial Filtration Efficiency (BFE) testing of medical masks and other filtration materials, helping determine how effectively a material filters out bacteria. For use with Bacterial Filtration Efficiency (BFE) Testing Apparatus. Recommended operating pressure of 10psi.

What is BFE Nebulizer Testing?

A BFE nebulizer creates a controlled bacterial aerosol that passes through the material that’s being tested. It’s a standard method for evaluating the ability of a medical mask or other filtration material to block bacterial aerosols, which is crucial for preventing the spread of airborne infections.

To simplify the nebulizer’s role, it works by:

  • Suspending bacteria (e.g., Staphylococcus aureus) in liquid and then using the nebulizer to turn it into an aerosol.
  • Exposing the testing material (e.g., a medical mask) to the resulting bacterial aerosol.
  • Comparing the number of bacteria passing through the material to the number in the initial aerosol to determine the BFE.

What are the Key Components?

  • A BFE testing system typically includes a nebulizer, an aerosol chamber, a cascade impactor (to collect and analyze the aerosol), and Petri dishes for culturing bacteria.
  • Standards: BFE testing is often conducted according to standards like EN 14683 (for medical masks) and ASTM F2101 (for other filtration materials).
  • Examples: Glass Expansion is an example of one company that offers BFE nebulizers and testing systems.
