I mean essentially unless a mask is one of the medically or industrially certified N95 and their ilk (which people are still discouraged from using due to shortages) I'd say it is hard to really quantify that one type of mask is better than another. Any covering that prevents you from spitting on people around you on accident should serve the purpose that health experts are recommending masks for. So I suspect this mask would serve both a public health and privacy protecting purpose.
