BingoNot sure how in any sane world wearing a cloth face diaper or a bulk-pack "surgical" mask over a true N95 mask would in any way be a substantive increase in filtering effectiveness. Given that the 95% effective rating of an N95 mask is reached through the incorporation of a middle layer of electrostatically charged fibers, the physics would say an additional layer of inferior mechanical filtration does bupkiss.
Here's a good article explaining the functioning of N95 masks
Based on the science, it makes sense that trying to sterilize N95 masks without a means to refresh the electrostatic charge would be folly and potentially dangerous.
some companies made a lot of money off “sterilizing” N95’s. Turns out it wasn’t such a good idea
