Demystify: 

Hi All,

Is anyone using the Ionized Hydrogen Peroxide Steramist system to disinfect surgical masks that contain a cellulose inner layer? Based on a previous study (https://tomimist.com/wp-content/uploads/2018/03/Surface-Compatibility-and-the-SteraMist-Systems-2.pdf), there should not be any compatibility issues with surgical masks that have a polypropylene inner layer. I do not think there should be the same issues present with the Vapor Phase Hydrogen Peroxide systems and cellulosic materials since the hydrogen peroxide concentration is much lower and there is minimal residence time due to more rapid H2O2 decomposition in the ionized systems (https://www..labrepco.com/wp-content/uploads/2018/09/Ionized_Hydrogen_Peroxide__iHP____vs._Vaporized_Hydrogen_Peroxide__VHP____1427129030.pdf). Do you anticipate there will still be some degradation of the cellulosic inner layer from the short-lived ions and radicals?

Thanks.

Regards,
Mark
