REBEL Core Podcast 32.0 – N95 Mask Reuse

Take Home Points

  • N95 masks ideally should be single use but in COVID19 times, safe reuse practices are critical.
  • The best approach to reuse is vaporized H2O2 and UV light decontamination with a total of 3 decon cycles prior to losing mask integrity.
  • A backup method of cycling between 4 masks is likely effective as SARS-CoV-2 cannot survive > 72 hours outside a human host in sufficient numbers to cause infection.
  • Ethanol soaks are effective in decontamination but destroy mask integrity and should not be use.
