I don't understand why there are 7 positive reviews because these masks are definitely not level 3 . They are at best level one. The quality is cheap, material is scratchy and masks are very thin , very easy to breath, which is not good since they have hardly any filtering . I am very disappointed , I am stuck with masks I can not use

Horrendous masks. PAPER inside shreds before you can even put the mask on. How can this supplier get away with selling this? Definitely not medical grade.

Not comfortable, feels like a regular mask and not a Level 3.
