<abstract displayLabel="Summary">A novel method for measuring the fit factor of filtering facepiece respirators is described. Measurement is made by the continual monitoring of the pressure produced by a volume of air injected into the respirator cavity, and withdrawn so that the added volume varies sinusoidally with time</abstract>
