That's the point. It does not say anything on the Box about being able to prevent covid-19 spread. Covid viruses are >0.1 micron. If your employer is making you wear a mask at work, clue them in on the many peer reviews on how masks, such as the N95 do not work, and causes the self-replication of bacteria inside the mask because you continue to exhale warm moist air that's just right for breeding the things that you don't want to breathe to make yourself sick. But don't believe me. Look it up.

I don't like the over the head make of these. The straps stretch but I prefer around ears and for the front to not look duck like. To fix, I trimmed off about half of the huge Seam and I wear under another mask so not using the head straps. They fit just fine that way. I do believe they are real N95. I don't believe Sam's Club would sell a fake product. I think some modifications on future masks should be better thought out.
