3M VFlex Particulate Respirator 9105, N95

They're totally fine, just wish they were individually wrapped

The metal nose piece should be a bit lower. The mask doesn't fit comfortably. It doesn't expand well and folds in the middle. Maybe because the mask is so large, that's why it doesn't fit well around the nose area for me. It's a great quality mask but the fit is not comfortable.

Easy to breathe through and the best respirator I have used for maximizing the overtones during singing while providing protection. Sturdy strap and comfortable, too. Not a fashion accessory, but high functionality for what I need outside of my work as a nurse.

Comfortable, good enough for light exercise as long as you don't get it wet, and flexible enough to provide adequate n95 protection despite any moving or turning your head and face may do. It even survives my wide-mouthed yawns without giving up on protection. I was initially doubtful of its string design (both securing strings emanate from the same region of the mask) but there appears to be no compromise in fit, comfort, or flexibility.

Best N95s money can buy - no other mask we've tried gives as good a seal. Plus they are very easy to breathe in - even to wear while working out and breathing heavily. These do not fog our glasses, and allow us to function with a high level of confidence that our lungs are being kept safe. Everybody's face is different, of course - but several of us find these respirators to be exceptionally good.
