Effectiveness of Ultraviolet-C Light and a High-Level Disinfection Cabinet for Decontamination of N95 Respirators
Category: Article Summary
Topic: Non-Pharmaceutical Interventions
- Cadnum et al. compared three decontamination methods for use on N95 respirator masks (n=3). A high-level disinfection cabinet that generates aerosolized peracetic acid and hydrogen peroxide achieved disinfection with a 31-minute cycle. Ultraviolet-C light reduced contamination but did not meet pre-defined criteria for decontamination of the viruses (6 log10 reductions). Dry heat at 70° C for 30 minutes was not effective for decontamination.
