How Surgical Masks are Made Tested and Used

Bacteria filtration efficiency in vitro (BFE) This test works by shooting an aerosol with staphylococcus aureus bacteria at the mask at 28 3 liters per minute This ensures the mask can catch the percentage of bacteria it's supposed to Particle Filtration Efficiency Also known as the latex particle challenge this test involves spraying an aerosol of polystyrene microspheres to ensure the

Dry Heat Ovens Can Effectively Disinfect N95 Masks

The initial testing on the 1860 model was at 250˚F (121˚C) for a duration of 60 minutes with a 30-minute ramp down and a 5˚C deviation These masks failed the qualitative fit test by EHS following this soak We then decided that temps were likely higher than they needed to be and cycles were too long The next attempt used the 1870 model N95's at 250˚F for 60 minutes These masks passed
