Love these!

These fit me well and are well-priced. Shipping & delivery went well.

Thank you for your review! Glad to hear the delivery got to you quickly.

Perfect for flying

I wore these masks for full days of travel and they were very comfortable and easy to breathe and speak in. Added bonus that I am officially one of the only people I know who haven't gotten COVID while traveling, and I give credit to these masks. All hail the duck masks.

Comfortable, well-priced N95

I have been wearing these masks daily for a 20-minute walking commute and 8-hour workday since January, and they are the most comfortable facemasks of any kind that I have ever worn. The design holds the mask away from one's nose and mouth to avoid muffled speech or impeded breathing. The head straps stay in place without digging in. I am very pleased with this design. The only improvement that could be made is that the white bendable piece for the bridge of the nose could be better adhered to the mask. It sometimes comes unglued at the edges of either side by the end of the day, but not enough to impair the seal.

BEST N95 ever

This is the best N95 respirator ever for the following reasons:
1. Cheapest/most affordable/lowest unit price N95 respirator on the market
2. Most comfortable duckbill N95 respirator on the market and probably the most comfortable N95 respirator on the market(The only one that might be be more comfortable is the readimask which I have not tried as it is too expensive.) Some people have even reported being able to sleep with it on without a problem, not that I have tried. It is so comfortable you can forget that you are wearing it. The duckbill design keeps it as far away from face as possible (except the edges) improving comfort and creating a nice air pocket to increase breathability.
3. Probably the most breathable N95 respirator on the market.
4. Unlike KN95s, Uses head straps instead of earloops that painfully pull on ears
5. Extremely good seal.
6. It is surgical N95 respirator so it is both an N95 respirator and surgical mask in one and provides protection against fluids. For hospital workers, it means you can take it into the OR without fear. For the rest of us, fluid protection is wonderful.
7. Stores flat before use to save space.

Only downside is it the straps must be manually separated before use.

It works

I am going on 80 years of age. I have never contracted covid or that horrible upper resp. virus when I was wearing this mask. When I went to a crowded grocery store without the mask I got two mild cases of Covid, and that upper respiratory virus which put me down for a month. There are no antivirals to treat it. I am back on the mask when I have to go shopping. I have tried a few other masks. This one is easy to breathe with and does not fog up my glasses. The only negative for me are the straps which I don't like. The reason for four stars. The important thing is the mask works and is the most comfortable I have used

We are so happy to hear that you are loving the protection provided by your Made in the USA masks, James! Thank you for your support!

Best mask in hot weather

I've purchased these and I'm so glad Armbrust carries them. They are the only ones that are comfortable in hot weather and are easy to breathe in. Thanks so much for these!

We are so happy that you are loving the comfort and breathability of your N95 masks! Thank you for your support!

great masks that fit most people, not petite heads

I have a small narrow head, and unfortunately these are a little to big, but if you make a pleat under the chin and staple it then it fits ok. The wide straps are nice as they don't tangle with your hair or pull on skin and distribute the pressure more than a narrow band does so they are great for comfort. Plus the reasonable price is great. I use these as my outdoor mask. I'm immunodeficient and there are a lot of people that are around near my yard, plus allergies... I don't use these as my indoor mask because I have MCAS so I wear a nuisance odor respirator when indoors due to the overwhelming amount of synthetic/toxic fragrances.

About to order yet another set of 300

I'm high-risk for covid but have a high nose bridge on an otherwise small face, so I both need the extra protection AND find that most narrow-enough masks are so tight top to bottom that they end up tightly stretched right over my nostrils and mouth, which is uncomfortably claustrophobic. Not these!

Several diligent KN95-wearers I know have gotten Covid for the first time recently, but so far I've stayed Covid-free and I like to think that these masks have been a factor (working remotely, good handwashing/hand gel practices, and avoiding crowded, poorly ventilated indoor spaces whenever possible have also helped, of course, and I'm aware that the "95" in "N95" is not "100", but the longer it takes for me to get Covid, the more doctors will know about treating it in immunosuppressed patients like me who can't safely be given Paxlovid without risking transplant rejection by going off their most important medication).

On the rare occasions that someone gives me an odd look due to the shape, I just stare at them, loudly quack once, and then go back to whatever I was doing. Never fails to elicit a laugh :D

Thank you so much for your review, Stephanie! We are so happy that you continue to love the protection and fit provided by your ACI N95 masks and we truly appreciate your support!

Great for singers

I'm a university voice professor, and I've been wearing these masks almost exclusively for when I teach singing (opera, jazz, pop, MT...)
Because of the shape and how the seam lies, these are IDEAL for allowing normal jaw movement for speech and singing. Unlike the fabric singer masks (which look even more like horse feedbags than these...), they are made of the proper material to be effective at reducing viral spread. Also, unlike the Gerson ones, the head strap material doesn't catch on your hair (it's a much softer, stronger material than the rubberband elastic I've seen on other masks).

Even though they look less fashionable than some masks - they do the job very, very well. I'm so glad I found these!

Hi Liz! We are so happy that you are loving your ACI masks and that you are able to use these when teaching! Thank you so much for your support!
