There are standards for everything manufactured from nuts and bolts to medicine, to NASA. So to what national standard are the masks being made? I see that goof SHAM WOW is back on the air pushing masks as well. There are countless ads for masks now and they all seem to cost the same. So what grade of material are they using? How are the masks tested for preventing entry through them? We saw at first four layers was the minimum but layers of what? I have yet to see the number of layers given in most ads. I have now about six different masks searching for the one easiest to breathe through. Only two are satisfactory for ease of breathing. So the question is in view of the soaring cases, do they work?
