Abstract
INTRODUCTION: Personal protective equipment shortages require the reuse of N95 respirators. We sought the necessary conditions for ozone to disinfect N95 respirators for reuse and the effects of multiple cycles of exposure.
METHODS: Portions of 3M 1870 N95 respirators were exposed to ozone at 400 ppm with 80% humidity for 2 hours to determine effectiveness of ozone on killing
RESULTS: Ozone exposure disinfected 3M 1870 N95 respirators heavily inoculated with
DISCUSSION: These results suggest that ozone is a feasible strategy to disinfect N95 respirators for reuse during this and future pandemics.
