Any views on masks with an active silver layer?
The basic idea is to upgrade from my current cotton masks to some masks which have 3 layers. Looks like a surgical mask. Two outer layers are "spunbond non-woven textile", inner layer is "non-woven melt-blown textle with active silver ions".
They claim the silver helps the mask self-disinfect and its effectiveness is similar to KN95. You can also reuse it (it should survive 20-50 handwashes at 30 degrees C, but doesn't need to be washed every time).
Is this just pseudo-science or should I upgrade?
They are in the process of putting up an English website at
en.ruskoambrela.sk (so they presumably think export restrictions are going to be removed soon).
