The respiratory protection afforded by a filtering face piece respirator (FFR) is dependent not only on its filtration capability but also on the face seal leakage that occurs at the face/FFR interface. The adequacy of the face seal is reliant on various factors, including the design of the face piece sealing surface and the pressures generated by the FFR tethering devices (e.g., straps, bands, and so on).Discontinuities at the face seal area (FSA) are responsible for the greatest portion of inward leakage of contaminants, with face seal leakage averaging 3–5 times that of filter penetration in a recent study.
