Compliance and tolerance of facemasks for extended periods are legitimate concerns. The goal of this study was to identify the physiologic and symptomatic effects of extended-use N95 filtering facepiece respirator (N95) compared with medical masks. We hypothesized that hospital personnel wearing medical masks alone would report fewer subjective complaints compared with personnel wearing an N95 with or without overlying medical mask.
