Improvement in Fitted Filtration Efficiency of N95 Respirators With Escalating Instruction of the Wearer.

ABSTRACT:

Introduction

Fitted filtration performance of an N95 respirator may benefit from differing levels of instructions.

Methods

Using a modified Occupational Safety and Health Administration fit test protocol, we measured fitted filtration efficiency for an N95 respirator in 21 screened, healthy participants given 4 levels of escalating instruction: (1) uninstructed (baseline), (2) written/pictorial manufacturer instructions, (3) step-by-step video demonstration, and (4) staff instruction (visual inspection of respirator fit and verbal suggestions to adjust when applicable).

Results

Baseline fitted filtration efficiency was not significantly different between participants with or without previous experience of N95 use. Clear improvements in fitted filtration efficiency wer
