REUSING N-95 MASKS - srlevine1 - 03-27-2020 An interesting note from Duke University... Quote:Duke Starts Novel Decontamination of N95 Masks to Help Relieve Shortages Makes me wonder if you could make your own unit using a fish tank and a cheap nebulizer? Considering the cost of masks, it might be cost-effective and pay for itself. RE: REUSING N-95 MASKS - Melman - 03-27-2020 I have worked with this technology. It requires very specialized equipment and environmental control with respect to temperature and relative humidity. It is actually a vapor and not an aerosol. What you propose may provide some surface decontamination but would not penetrate. Also, it would wet the masks. I don't know if that would harm them or not. Vapor phase hydrogen peroxide does not wet the surfaces to be sanitized/sterilized. In fact condensation reduces the efficacy.

Wetting the masks with alcohol or bleach damages the masks according to Stanford Medicine. I'd think that could apply to other liquid disinfectants as well.

I have a box of 20 masks I bought before the crisis and I was going to simply line them up on a shelf in my garage as I use them. I only wear them to buy groceries and Dr. appointments so they should last for weeks. My plan was to let them dry in the hot garage and re use them if I needed. Any thoughts? RE: REUSING N-95 MASKS - 70sSanO - 03-27-2020 I have tried to find the effect of using So Clean. It is tough to find anything specific on using ozone cleaners and nothing specific to disinfect N95 face masks. People have put their CPAP masks in them including those with the quiet air elbow. FDA and Resmed do not recommend using them, but I have not heard any adverse effects on CPAP masks if they are left to air out. But, I would think putting them out in the sun for a week or two is probably the best course of action. John |
