Thanks for an informative (and entertaining) video. My testing is similar to that of Aaron Collins, but without his expertise or the lab grade particle counter.ģM Aura 9205+ - Shipped and Sold by AmazonīNX F95B – Shipped and Sold by BNX AccuMed* I'm also not doing the official 4 stage OHSA fit test. Because of that fit factor can be below 100 and still be within minimum expectations for a perfectly fitted N95 mask using the N100 test. I'm using an N100 style fit test of all ambient particles not the officially designated OSHA N95 protocol that counts only non-penetrating particles so that only leakage around the mask is measured – some filter penetration of ambient particles is expected. Interior Depth – 8.5mm (Working part of the mask, not counting tabs.) Interior Depth – 9.5mm (Working part of the mask, not counting tabs.) (Measured by opening the tri-fold mask fully, then folding in half so it looks like a bi-fold.) The interior depth of the working portion of the mask is also a bit shorter. The top panel is shorter, and the nose wire pocket slightly lower. It is not as big as the 3M, in spite of the front panels being essentially identical in size. The measurements seem similar to the 3M Aura 9205+, but the BNX F95B really is, as advertised, a small/medium mask. To get some additional perspective of where the BNX F95Bs fit in the pantheon of respirator-grade tri-fold masks, I also included a test of the LG Airwasher, a mask I had to ditch because of the leaks I could clearly feel at my nose bridge. I tested using a TSI particle counter mask fit tester - kind of like if you ordered Aaron Collins on Wish dot com. Black masks are fun, but KF94s don't fit me well enough to be protective. I wish the straps were more durable, but they are definitely a high quality protective product.I just got my BNX F95B black N95 masks from Amazon and I really, really want them to be good enough to wear instead of my 3M Auras. The fit is impressive and secure, and I use these with confidence daily, both at work, and in general for virus avoidance. These are better than other masks, though. It seems the style just creates less resistance for breath to exhaust upward, than forward, and that can fog lenses. The nose bridge seal is sometimes the issue, and is easily fixed by adjusting the bridge wire. Other styles of 3M N95'S just have more durable straps, that dependably allow more use.Īlso, despite claims, they do fog my glasses. with cleaners, and the fabric isn't full of dust, the fabric is viable. As long as you don't destroy the electrostatic properties of the fabric e.g. 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. On me, the loss of stretch didn't seem to affect the seal until 3-4 days of use. These have blue rubber straps, and they wear fine for a couple days, but beyond that, they don't snap back completely. 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. Great fit, with a little effort, high quality mask.įiltration seems excellent, sponge bridge seal is great, metal in bridge is strong and of good length.
