I do not know the actual shelf life on those items. MAybe one of our fact checker nerds could research that.
Assume masks that have plastic/filters etc have higher likelihood of deterioration.
Even all of our "sterile" supply has expiration dates; sterile irrigation fluids, sutures wound swabs etc. even autoclaved metal surgical instruments have a specific shelf life.
