MSU Extension Dry Heat Decontamination System For N95 Respirators

MSU Extension Dry Heat Decontamination System for N95 Respirators

MSU Extension has a pending application for an emergency use authorization from the U.S. Food and Drug Administration for a Dry Heat Decontamination System for N95 Respirators. The MSU Extension Dry Heat Decontamination System for N95 Respirators is designed to decontaminate used N95 respirators for the same health care worker to prevent exposure to aerosolized infectious particles. This is especially critical when supplies of N95 respirators are insufficient during the COVID-19 pandemic. Scientific literature was reviewed and adapted for food-processing practices using large-scale commercial ovens.

Michigan State University is openly sharing this information prior to receiving the EUA to allow others to more quickly develop their own processes and procedures. When the End User Agreement is completed, the applicant will receive a packet via email that includes:
