⚠️ N95 Mask Decontamination & Reuse

N95 Mask Decontamination & Reuse

With the currently evolving global health emergency related to the SARS-CoV-2 Coronavirus many hospitals are concerned about the short supply of N95 masks. As such, the question of whether UVC can be used to disinfect / decontaminate these masks has repeatedly been asked.

This is an evolving topic so we will update what we know as it changes.

Presently the best information we have found is from Nebraska Medicine, https://www.nebraskamed.com/

Your RD UVC machines are well equipped to perform the disinfection because they come with the necessary UVC measurement sensors thereby ensuring proper dose delivery has occurred.

We recommend following the Nebraska Medicine protocol per the following documents:



When using the RD UVC system use the UVC sensors as follows:

  • To extend the number of reuse cycles place the closest emitter lamps 5 feet from the clothesline;
  • Use 2 UVC sensors;
  • Place one UVC sensor at each end of the clothesline on a shelf or table at approximately 40” off the floor.
  • Place each sensor on its side, facing the emitter;
  • Use the COVID-19 Dose setting;
  • Run a job to completion on one side of the clothesline;
  • Reposition the system to the other side of the clothesline, reposition the sensors and run the job to completion.

The COVID-19 Dose must be added to your machines by Steriliz. Please e-mail your request to support@steriliz.us and include “N95” in the subject line.

Please let us know if you need further information or assistance.

Thank you,
