Filtration efficiency of surgical masks

PFE is a quality indicator for surgical masks and is not an indicator of protection performance. It measures how well the mask filters out particles such as viruses and other submicron particles. The filter media of a surgical mask with a very high (> 95%) PFE may be less than 70% efficiency under NIOSH certification test methods.

Comparison of Mask Standards, Ratings, and Filtration ...

Single use masks (normally one layer, very thin) are typically only effective at capturing larger dust particles, but can do so fairly well. Surgical mask standards have higher requirements for capturing virus-sized (0.1 micron) particles, however they vary by region. Pollution masks (respirators) typically capture >90% of virus-sized particles.
