The U.S. Food and Drug Administration (FDA) reminds reprocessing staff in health care facilities to use the correct decontamination cycle associated with certain models of the Advanced Sterilization Products (ASP) STERRAD Sterilization Systems and to only decontaminate compatible N95 or N95-equivalent respirators for reuse during the COVID-19 pandemic.
ASP STERRAD Sterilization Systems use vaporized hydrogen peroxide to decontaminate medical devices. Only the combination of certain models of the ASP STERRAD Sterilization System and their associated STERRAD Decontamination Cycle listed in the FDA’s Emergency Use Authorization (EUA), and shown in the table below, are authorized for the decontamination of compatible N95 respirators.
| ASP STERRAD Sterilization System | STERRAD Decontamination Cycle |
| STERRAD 100S | 100S |
| STERRAD NX | Standard |
| STERRAD 100NX | Express |
