Great fit, with a little effort, high quality mask.
Filtration seems excellent, sponge bridge seal is great, metal in bridge is strong and of good length. No certification documentation, just the standard 3m stampings on the masks, but this company has been selling 3m forever, and can be audited, so no legitimacy concerns from me.
These have blue rubber straps, and they wear fine for a couple days, but beyond that, they don't snap back completely. On me, the loss of stretch didn't seem to affect the seal until 3-4 days of use.
Yes, I know these are disposable, but I use these for construction/factory work, and blow them out with compressed air, and use them till they can't be cleared, or the seal fails. As long as you don't destroy the electrostatic properties of the fabric e.g. with cleaners, and the fabric isn't full of dust, the fabric is viable. Other styles of 3M N95'S just have more durable straps, that dependably allow more use.
Also, despite claims, they do fog my glasses. The nose bridge seal is sometimes the issue, and is easily fixed by adjusting the bridge wire. It seems the style just creates less resistance for breath to exhaust upward, than forward, and that can fog lenses. These are better than other masks, though.
The fit is impressive and secure, and I use these with confidence daily, both at work, and in general for virus avoidance. I wish the straps were more durable, but they are definitely a high quality protective product.Read full review
