Unless you're some kind of hacker who can add their product to this list: https://www.cdc.gov/niosh/npptl/topics/respirators/disp_part/n95list1.html https://www.cdc.gov/niosh/npptl/topics/respirators/disp_part...
It seems pretty hard to counterfeit.

- goodside 5y agoThat’s my point — you can never trust a KN95 because it’s trivial to manufacture something that looks and feels like a KN95 but isn’t real. A NIOSH N95 isn’t like that — the straps require an unusual amount of stretch and tension, and they’re expensive to make. You’d notice immediately if you purchased a counterfeit mask, because the braided material on more expensive N95’s is unique in a way you can feel — it stretches farther than any rubber band you’ve ever used, and it doesn’t snap or lose tension from overstretching.
- dragontamer 5y ago> and it doesn’t snap or lose tension from overstretching. Not quite. The big-name brands (Moldex, 3M, Kimtech) have good elastic. But I've been shopping at the $1 (and below) price point, and there's some pretty crap N95 masks out there. There's a lot of smaller brands trying to make a name for themselves right now, and are just barely qualifying for N95 ratings. Still, the crappiest N95 is leagues better than the best KN95 I've ever used. ------------- I'm mostly willing to give the smaller manufacturers a try. Though with Omicron numbers falling in my area (about damn time), maybe this will all be behind us soon...
- apendleton 5y agoThe advisory suggests that there are knock-offs fraudulently marked with approved brand names, so you'd need to order direct from the manufacturer to be sure.
- galangalalgol 5y agoWe got some of these, and my question is if they are any worse than the double layer knit cotton masks (with no nose wire) that my workplace was issuing. If these were marketed without the false claims, and only had the actual filtration specs, would people just think they are an acceptable step down from the real thing? The tests from a post a few days ago seemed to say most were at least in the high 85% but what is a cloth mask?
- pkaye 5y agoAaron Collins on YouTube tests a lot of the masks widely available in the market for filtration and pressure tests. He compiles a Google docs sheet of his findings. https://www.youtube.com/user/coll0412/videos https://www.youtube.com/user/coll0412/videos
- throwaway81523 5y agoDo you have a link to the google doc? I didn't immediately see one on the video page. I wasn't up to watching any videos right now but will try to watch at least one sometime. I will also try to order some masks from the guy who tested the Amazon masks (I'll have to find the link again).
