Customer Reviews
Still wearing these during air travel. Don't feel foolish about it either. Feel safe.
Hi Frances! We are so happy that you continue to love your Aegle N95 masks and we truly appreciate your continued support!
All of the N95 masks I tried ended up turning the bridge of my nose red and it was painful. So I purchased the Armbrust variety pack and wore each for one day. Taking price, protection, comfort, and my sensitive skin into consideration, the Aegle masks were my favorite. Combined with eyeglasses and a face shield, I'm ready to enjoy a football game in a crowded stadium filled with cheering fans. You can't go wrong with an Armbrust mask, but these Aegle masks are a really good deal. And they're Made in the USA.
Glad to hear these Aegle N95s fit so well!
These are my husband's & my favorite N95 masks. I'm glad they're still available.
We are so happy that you and your husband continue to love your IFM N95 masks, Nancy! Thank you so much for your continued support!
Surpisingly comfortable in all respects. Fit is good. I rely on them for situations where N95 mask is preferred. Happily discovered after much trial and error.
Good masks Good fit
My favorite N95s I've ever used. Great seals and great fit.
Hello and thank you for your review! We are so happy that you are loving the fit of your Aelge N95 masks and appreciate your support!
Good masks
I have had a subscription since 2021. I tried several different brands of N95s prior to finding the Aegle N95. They're comfortable, easy to breathe in, and have a nosepiece that facilitates a great seal. I also love that I can get them with headbands because I hate ear loops. Additionally, the customer service at Armbrust is first rate, and I appreciate and enjoy the educational videos that Lloyd posts that explore different types of masks with their plusses and minuses. This is a company you can trust.
Hi Vivien! Thanks so much for your feedback and more than kind words - we truly appreciate them and your continued support with help bringing strategic manufacturing back to the USA!
I ordered the N95 from Armbrust based on a recommendation from my adult son who has researched the mask industry offerings extensively. He was so right about these masks. They are proven to be protective based on materials and construction. But they are also by far the most comfortable protective mask I’ve ever worn. It’s easier to breathe behind it, it is softer and not so stiff, and the top of the mask at the bridge of my nose fits with a good seal which means my sunglasses don’t fog up. Only wish my son had discovered these sooner!
We thank you and your son for your support and research!
Ordered 20 of these masks in light of the wave of covid, influenza and RSV. Continue to use Armbrust surgical masks for daily errands, etc., but bought these for travel or when extra protection in crowds is advised. Well constructed, as I have come to expect with Armbrust, with nicely integrated straps and wired nosepiece, and of course, NIOSH approved.
Thank you for leaving your thoughtful review.
We are happy to provide quality N95s like this one, and are so pleased to hear you have found this model comfortable! Thank you for giving us the honor of protecting you with quality masks like this one.
