Abstract

Abstract We have demonstrated the effect of covering an N95 filtering facepiece respirator (FFR) with an overlying face mask. In total, 100 participants successfully completed quantitative fit testing wearing a 3M 1870+ FFR. Among them, 13 (13%; 95% CI, 7%–22%) failed subsequent fit testing when simultaneously wearing a Halyard 47117 procedural mask over the FFR.
