USA-Made Flat-Fold Surgical Masks (510k)
SKU: KN95-ARMBRUST-FOLD-WHITE-BOX-1X20-R
The worlds most popular mask shape
is finally being held to an American standard.
Throughout the pandemic we tested hundreds of our competitors KN95 masks to see if they actually protected people. The manufacturers of these unregulated respirators love to make all sorts of claims -- especially that they are "made in FDA-Registered facilities," which is meaningless since the FDA doesn't regulate KN95s.
The Chinese GB-2626 KN95 standard is good, but since it's a foreign standard it lacks any kind of regulatory oversight. And, our hundreds of tests prove that many foreign made KN95 masks are making claims they can not back-up, too.
Your health is too important to leave to chance. At Armbrust American, we hold ourselves to a higher standard.
The Best of Both Worlds
When done right, the flat-fold KN95-style respirators provide a better seal than a traditional 3-ply surgical masks, which is why we've decided to combine the best of both worlds and make ourselves accountable across the board.
Our Armbrust USA-KN95 is an FDA-cleared surgical mask, a 510k mask with the improved fit/seal provided by the KN95 shape.
Designed, developed, and manufactured in our American facilities, each mask is rigorously tested for quality and safety.
Our cutting edge, beyond clean facilities are working at full speed around the clock to produce these regulated, and damn-near perfect masks.

Below are independently verified lab results from the several required tests, in which Armbrust masks returned better margins than required by established standards.

Surgical Mask Lab Results:
BFE Test ( BFE Test Full Report)
“Bacterial Filtration Efficiency” is a test that shows the amount of bacteria that can get through our masks. Nelson Labs used aerosolized Staphylococcus Aureus to test Armbrust masks, and despite accidentally using nearly 10 times the amount that is usually required for a test like this, they passed with 99.2%+ Efficiency -- well above the ASTM II & III requirements.
PFE Test ( PFE Test Full Report)
“Particle Filtration Efficiency” tests the size of particles that can pass through a mask. Armbrust masks were well above the 98% required for ASTM II. It should be noted that a PFE rating of 98% typically blocks most particles down to about 0.3 microns — the Staphylococcus Aureus bacteria used in our BFE test can get as small as 0.1 micron (about the size of the CoronaVirus).
Differential Pressure Test ( Differential Pressure Test Full Report)
This test is used to determine the breathability of Armbrust surgical masks. Sure, you might be able to block viruses, but can you still breath? Even with our higher BFE of 99%+, we passed with much better breathability than normal — in most cases under 4.9 (mm H2O/cm2) versus the requirement of being less than 6.0 (mm H2O/cm2) — also attached.
Synthetic Blood Penetration Test ( Synthetic Blood Penetration Test Full Report)
This procedure was performed to evaluate surgical face masks and other types of protective clothing materials designed to protect against fluid penetration. The purpose of this procedure is to simulate an arterial spray and evaluate the effectiveness of the test article in protecting the user from possible exposure to blood and other body fluids. All 32 masks tested passed synthetic blood spray at 160 mmHg with no penetration seen. ( See the test in action)
Flammability Test ( Flammability Test Full Report)
Meant to ensure that a face mask will not ignite and burn for more than 3.5 seconds. All of our masks burned for less than one second, passing this requirement.
Cytotoxicity Test ( Cytotoxicity Test Full Report)
Designed to test if people will have a reaction when wearing our masks. On a scale of 0–4, with zero being no reaction and four being a severe reaction, masks that on average hit a 2 or lower pass this test. All of our masks received a grade of 0 and passed.
Irritation Intracutaneous Toxicity Test ( Irritation Intracutaneous Toxicity Test Full Report)
"The purpose of the study is to determine the potential irritation effects of the test article extract as a result of an intracutaneous injection in New Zealand White rabbits."
Sensitization Kligman Maximization Test ( Sensitization Kligman Maximization Test Full Report)
"The purpose of the study was to determine the potential allergenic or sensitizing capacity of the test article. The study was used as a procedure for screening of contact allergens in guinea pigs and extrapolating the results to humans, but it does not establish the actual risk of sensitization."
Customer Reviews
I’ve been steadily purchasing these mask for myself and family now for a few years. Originally it was just the regular surgical mask now the KN95 and these are hands down the most comfortable and most important to us USA made mask around. ☝🏾👌🏾💯
With the endless trips and waiting I’ve had to do in hospitals for loved ones this is the only mask I trust, period!
It covers my face and with the recent trip I made to buy my very first pair of glasses, absolutely no fogging.
These also help tremendously with my allergies 🤧. I have the fluffiest that you can imagine and when she’s blowing that Akita-mix coat of hers these are seriously a lifesaver & game-changer.
TY 🙏🏾👌🏾👍🏾
A tad tight for this large head but still comfortable and secure. The duck bill straps on another model were breaking like crazy so now I feel a lot more secure when I go out.
Great customer service! Lloyd Armbrust, manufacturer and owner helped me get the right masks. After two or more years of fumbling around, I finally feel more secure.
Made in the USA as well!
Thanks!
Thank you so very much for your review and support!
My Hungarian Puli and I are a pet therapy team at our local medical center. Covid, RSV, and Flu cases are on the rise - so much so that I debated taking a "vacation" from volunteering with patients until the numbers once again begin to subside; however, because these masks have a greater than, or equal to, 98% filtration rate, I decided we would continue visiting patients. I have been wearing Armbrust masks since the beginning of Covid and I have not contracted the virus! So, we will continue volunteering, taking all possible precautions, and putting our trust in Armbrust masks! BTW, I don't have a photo of me in a mask but I will share a photo of my certified therapy dog! She wants to know when Armbrust will start making masks for therapy dogs?!!!! (Just kidding!)
The Armbrust flat fold mask seems to of good quality and fits my face very good.
Hi Michael! We are so happy that you are loving the fit and quality of your Flat-Fold Surgical Masks!
These are good masks! I used to buy KN95s from my local hardware store, but then I did some research and found out that they were likely fraudulent KN95s. I like my Armbrust masks because I can trust that they are genuine N95 masks.
Hi Daniel! Thanks so much for your review! We are so happy that you found us and that you are loving your new masks!
Came for the “made in USA” aspect, stayed for everything else! Have reordered numerous times. Good fit, breathable and have kept me well. My last order, I had to place for some of the 5-packs as my usual 20-pks were out of stock. Turns out I like the fact that these are individually wrapped …wonderful for keeping extras in purse or car.
Hi Felicia! Thanks so much for your feedback! We are thrilled to hear that you are loving your KN95 masks as well as the fact that they are individually wrapped!
This version of the surgical mask fits me much better. No gaps on either side of my face. I put it to use just recently. My 88 year old mother was in the hospital and had to wear a mask to visit her.
Thank you for trusting us!
Great quality masks made in the USA
Thank you for your review! We're glad to hear that you're happy with the quality and functionality of our USA-made flat-fold surgical masks.
These masks are great…. quality exceptional and fit is comfortable!
We are happy to provide masks wit quality fit and quality protection!
I love this company and all their masks, but recently with the white KN95 flat fold masks, 3 broke when my husband went to put it on. Specifically, one ear loop each time. I hope this is not going to be a recurring issue because we do love the masks. They are pricey but worth it if the quality remains.
Thank you for your review! We always strive to make the perfect mask, but sometimes we will still fall short.
I have reached out to your personally to ensure we can get you taken care of.
