Explainer: Testing the Efficacy of Protective Face Masks

The Bacterial Filtration Efficiency (BFE) test. This test indicates how well a mask filters droplets containing biological agents such as bacteria or viruses. With SARS-CoV-2 thought to be transmitted through droplets, the BFE test is a proxy for the efficacy of a mask in preventing such transmission. Studies indicate that a cough typically expels droplets between 5 and 20 microns
