A disposable 3ply face mask/respirator is composed of 3 layers of filter substrates:
1st : Outside layer-PP non-woven;
2nd : High density filter layer-PP melt blown;
3rd: Skin care layer-PP non-woven fabrics.
It fits over the nose and mouth. It removes very small particles from the air you breathe. These particles include germs (like viruses, bacteria, and mold) and other kinds of dust. The disposable mask does not have replacement parts, that is meant to be thrown away after use.
