What protection factor is associated with Powered Air Purifying Respirators (PAPR) when worn as full-face protection?

Explanation:
Assigned Protection Factor tells you how much protection a respirator provides by reducing the amount of contaminant you breathe. For a powered air-purifying respirator used with a full-facepiece, the standard protection factor is 100. In practical terms, if the outside contaminant concentration is C, the air inside the facepiece is expected to be at most C/100, assuming the unit is used correctly and the fit is good. The positive pressure from the blower helps prevent inward leaks, giving more protection than many non-powered tight-fitting full-face respirators, but not as much as loose-fitting PAPR configurations, which can offer higher protection (around 1000) because they don’t rely on a face seal. Real-world protection can vary with fit, airflow, and filter condition, but 100 is the typical assigned value for full-face PAPR use.
