Demetech N95 mask is more rigid than 3M N95. The rigidity caused imperfection fitting around nose bridge and glass foggy if people wear glasses. Slighty better breathing with 3M mask than Demetech mask. Not sure if Demetech mask would block more particles to release to the outside environment.
Thank you PURDefense, having a reliable supplier of PPE right now is so important and I am glad I can rely on PURDefense
