Performance of two respiratory protective devices used by home-attending health care workers (a pilot study).

Objectives: This pilot study aimed at determining the Workplace Protection Factor (WPF) for respiratory protective devices widely used by health care workers to reduce exposure to potentially hazardous aerosols when attending patients in their homes. Two devices were tested, an N95 filtering facepiece respirator (FFR) and a surgical mask (SM).

Methods: Three home-attending health care workers were recruited, medically cleared and fit tested.
