Submitted by a user, This 3M 9210+ mask gained high marks from our testers. While this is a certified N95 mask, its done in a boat style that is more similar to a KF94 than a typical cup-style mask. As one of the largest U.S. manufacturers, 3M has a track record for quality, with 99.93% filtration according to our tests.
It's worth noting that this mask's packaging seems off, as do the color of the straps -- indicating that they may not have come direct from the manufacturer. Remember, the best way to ensure you're not getting counterfeit masks is to buy directly from the manufacturer or an official distributor (check the manufacturer's website for that information).
