This is something Lloyd will have to be careful with. In the NIOSH test the mask is beeswax sealed to a flat plate, then the *entire* mask has the 85 liter per minute of flow go through it. In this clamp system only a small portion of the mask will have the airflow go though it. In the filtration world what we care about is the face velocity, or the flow rate / surface area. For almost all filter media, as the face velocity goes up, the ability of it to filter particles in this size range goes down. So the fact that the clamp system only tests a small fraction of the mask, thus a higher face velocity, this is a *harder* test than NIOSH. This mask in a true potted beeswax test may do >95%.
I mean the guy manufacturers his own masks that don't seem to sell, it's clear to me why he would want to discredit any other manufacturer for personal gain.
@@RR-wg1fk He is not even listed on the CDC website as a NIOSH approved facility. You can Google CDC N95 masks and search for him, he's not there. Is it any wonder that his masks tests higher than 3M, Honeywell, Kimberly Clark and every other known reputable N95 manufacturer? Could it have anything to do with the fact that it is a direct conflict of interest, given that he is a competitor? Not saying the videos are deliberately dishonest, but they are questionable at best.
@@joseperezmusic3748 he doesn't make N95s. He sells N95s that are made by other US based companies, KN95s, and surgical masks. He's tested a bunch of masks that have out performed his including some N95s. And he said that the test of his surgical mask did better than usual. And this is only based on material, not the seal so an N95 would out perform his the vast majority of the time because of the headstraps/meeting fit testing reqs.
@@RR-wg1fk so then you haven't seen their N95 cup style mask test video below? Also as mentioned below, take a very close look at 1:12 and 1:25 mark, compared to the 4:32 mark.

Thanks for being honest about this situation and providing a link to the BNX testing video. I'm so relieved, as I have stocked up on BNX KN95s and N95s, and a health-compromised person uses them. My heart sunk DEEP after seeing your testing video. You might want to re-test the masks yourself. (This makes me also wonder about your test with SupplyAid, as I've used those myself and I like them a lot. They seem pretty substantial, don't stink-rather miraculous, that-and fit me to a tee.) I enjoy your videos, BTW. TY again.
My theory on why the test failed to meet GB2626-2019 KN95 standard is because of the way they embossed the "BNX" brand/logo. The embossing process sometimes creates unwanted holes in the masks fabric that allows particulates to go through.
But they use the same bifolds with their bifold N95 masks, so that is then implying that their N95 masks are breaking NIOSH standards and that's a pretty serious thing to say. NIOSH tested these same bifolds in order to certify them...so what is this whole thing about then
@@jamesk7178 I am going off experience alone. I had masks with logos embossed on them, and *some* of them had holes in the embossing which leads to leakage.
Thanks for this review! I have their Accumed BNX N95 mask (model H95W Approval TC-84A-9315) but I find it somewhat restrictive to breathe in. It could be that I’m not accustomed to N95 masks. Realizing I’m comparing apples to oranges here - I also purchased a 30-pack of Armbrust ATSM 3 blue surgical masks and I love them. I also love the resealable bag.
keep in mind that its really easy to fail a test if not done correctly like placing it properly or intentionally misplacing it. Note at 1:25, its actually showing 99.182% and 98.927% before he pans away. He's also upcharging his mask by 100%. IFM is selling N95 mask directly at $25 for a box of 25 N95 mask. He's selling the same box for $49.95. If he's really doing this for goodness of his heart, I don't think trying to get reseller profit of 100% is the way to go
@@itchyhands7874 yeah this has been brought up several times… what you’re seeing is the previous test results from the last mask before the machine resets. That mask that did 98% was actually our KN95.
@@NOT-FINANCIAL-ADVICE. the bifold is the same in both models. the only difference is the KN95 has ear loops and N95 has headbands. Which makes the test by Armbrust questionable because the same bifold was approved by NIOSH
Hello, I have watched almost all of your videos and appreciate what you are doing with the testing. I'm still very confused on what mask will protect my 70 year old mom she likes the ear loop version, do you have a website that shows all of you findings?
@@LloydArmbrust Please. PLEASE test their NIOSH N95 mask, p.n. H95B, or H95W. As those masks are marked NIOSH, failure to a standard becomes a bigger, different issue.

@@NOT-FINANCIAL-ADVICE. I think this was just a bad batch. I spoke with the CEO and we are working with them to get to the bottom of this. These guys are legit... their batch size is REALLY small (like 2,000) by comparison ours is between 40k-500k depending on the shift. They said they pulled the lot number they had in storage and tested it fine... could be something with Amazon's fulfillment but we will get to the bottom of it.
The best mask is the one you will wear consistently in all indoor public spaces. Ideally it will seal to your face and filter out particulate matter. That being said, N95>KN95=KF94>surgical>>>procedural (those flimsy blue ones you often see).
I’m definitely into it. I also noticed the embossing on the mask is transparent. Don’t think there is any way to get proper filtration with a see-through material of any kind. So it’s leaking like a sieve.
May I know why your machine shows 98% in the 1:12 and 1:25 mark but shows 92% at the 4:32 mark? Also, how many mask did you test exactly? How come there are 66 samples shown in the screen at the 4:32 minute mark? edit: Looking at your website, it seems the mask you rated the highest.. happens to be the very same mask you are selling. In fact, you just happen to sell 4 out of your top 5 rated mask( or maybe all 5?). I really want to believe you but its tough when you are obviously bias. 3M has been the staple of N95 mask manufacturing but they are not even in the top 10.
I know!!! If someone sends me an awesome American-made mask that does well I reach out to the company and ask to sell it! So many masks that are better in different ways than my masks or respirators… I can’t make them all!
@@RR-wg1fk what are you talking about? The video clearly shown at 1:25. The datapoints reset to just 1 interval and showing 99.182%. So the 99.182% belongs to your mask or BNX's mask?
Thanks for these reviews. I always appreciate them. BNX also makes N95 masks that are NIOSH approved. They claim better than 97% efficiency achieved in independent testing for their N95's. But I would trust your testing more!
supposedly NIOSH approved? it's right on the NIOSH database as approved...lets not get over ourselves and try to think individual people are more trustworthy with test results compared to NIOSH. NIOSH is the gold standard
Manufacturing in the real world, produces some defects. We are probably dealing with a lot number issue. Maybe someone changed what seemed to be a minor thing.
Armbrust is not sealing the mask properly on the machine. Need to use hot glue or beeswax to complete the seal before running the test. Also, why testing only 1 mask? Armbrust also claims that Kimberly Clark N95 fails below 95%, and Kimberly Clark is a multi billion dollar US company. I think Armbrust needs to double check his testing procedures. Looking on CDC website we see Armbrust’s facility is not even NIOSH or CDC approved, as Armbrust is simply slapping his logo on someone else’s N95 masks. Armbrust doesn’t even manufacture his own N95 masks and thus it makes sense why he does not know how to test them properly either
Maybe you’re right but I tested 30 masks that day that all hit 98-99% before and after this test (and the Kimberly Clark mask).. including a 3M aura that did 99.9%. Why did all of those pass fine? To be sure that the BNX was bad I did test another mask from the same box and it actually did worse but I didn’t record it so it’s clear the box is bad. The reason I don’t normally test more masks is… well… because i have shit to do 😉
@@LloydArmbrust Why are there so many inconsistency with what you are saying. Here you said that you tested 30 mask before and yet in your video at 5:38 said that you calibrated your machine right before this test and the first mask you tested is the BNX mask.
