Knowledge is power.
But are these silver masks functional in their main purpose of protection during Covid? Are the fibres made so thin and close to enable filteration of partiles and alow ony air? I have not seen. such a mask.
I visited net and found a website marketing protective silver maska. I think it is a US website. The details there are ...."Reusable, washable face masks with XSoft silver fibers......but using an additional lining of WaveStopper fabric containing 50% XSoft silver fibers." They have added a disclaimer "These are NOT direct substitutes for N95, surgical, or procedural masks and are NOT FDA approved."
