Why did this mask fail?
Country of Origin
Kathleen, I believe this mask failed due to the pressure drop exceeding the 250pa N95 standard. The filtration was good, but the pressure drop means the mask may be hard to breathe through, especially for long periods or during exercise.
Could someone tell me why these 3M 1860 N95 respirator masks failed? I have a whole box of them and am concerned now that they are useless. How could they be fake if they have the NIOSH certification stamped on them? I would appreciate any information on this as I rely on N95 masks to protect myself and my daughter who is very at risk for Covid complications.
