Great survive

The quality of the mask is exceptional. It's an upgrade from the 3M 8210V in both comfort as well as the robustness of the elastics. For Covid19 protection, I use this mask along with a surgical mask over it because the one-way vent does not protect others from me. The second mask also affords me an extra layer of protection from others. On the 3M website, Stauffer is listed as an approved seller so I was confident that these masks are not counterfeit. The masks arrived in 3M factory packaging for the qty-10 as opposed to some plain plastic bag bulk packaging. The detailed 3M instruction sheet was in the box. The pricing was so good that I called 3M to verify that Stauffer was indeed still authorized, which was readily confirmed by the 3M representative. Shipping time was FAST!
