I will let her know that she is mistaken and they no longer need to fit test n95 masks...  |

Your paper masks must be much fancier than any N95 disposables I have ever seen. So an aluminum band you bend to seal with one elastic cord stapled to them pulling the mask in half. No face seal. Pleated paper. No four point strap actually pulling a gasket to your face. These are all signs of a mask that will never achieve a seal. Especially when talking or moving your jaw. If you push the mask onto your face and breath deep for a negative pressure test good on you. As soon as you remove your hand you have no seal. The difference would be like a safety glass or goggle. Do you wear safety goggles or glasses to intubate TB patients?

Everything in this world is given an expiry date. What would actually expire on these masks? Honest question. Are they covered in a chemical or compound of some sort? Do you know? As far as I can tell its just a filter membrane. Not sure how it would expire.
