PeroxyChem develops high-purity solution for use in N95 mask sterilization and decontamination

As supplies of filtering facepiece respirators can become depleted, the Centers for Disease Control and Prevention recommends practices for limited re-use of N95 or N95-equivalent filtering respirators in the US.

Meanwhile, the Food and Drug Administration issued an emergency use authorization on sterilization of medical devices that would open up the re-use of N95 masks originally designed for single use.

Low temperature sterilization systems mainly use vaporized hydrogen peroxide (VHP) to sterilize reusable personal protective equipment, such as N95 and N95-equivalent respirators. The VHP decontamination process is proven to destroy a wide range of microorganisms, including bacterial spores, viruses, and fungi. PeroxyChem, recently acquired by Evonik, developed a high-purity solution for use in the VHP process that can be used directly for medical sterilization, including mask decontamination, without additional modifications.
