What was the Breathe99 Mask designed for?

The Breathe99 Mask is the result of 4+ years of human-centered product development, originally geared towards protection from air pollution, smog and wildfires. The design was adapted during the Covid-19 pandemic, with the removal of the exhalation valve to cater for the growing respiratory protection needs of global citizens.

Who designed the Breathe99 Mask?

Behind the Breathe99 Mask, there is a team of designers, engineers and medical-device specialists with the goal to create a low-waste, durable alternative to N95 and other disposable masks. The result is high level protection in a sustainable, lightweight design that is ideal for extended lifestyle use.

Is the Breathe99 Mask sustainable?

The Mask is made from durable materials that can be washed and reused hundreds of times. Using the filters is more affordable over time than disposable masks, and reduces waste by up to 80%.

Where is the Breathe99 Mask produced?

The Breathe99 Mask is designed and produced in the USA. We work with ISO-certified manufacturers and suppliers based in the Midwest to ensure the quality of all of our products.

Find your fit.

Use the following sizing guide to ensure the Breathe99 Mask is right for you.

Breathe99 measurement nose to chin

Measure nose to chin

Use a piece of string or a ruler to measure the distance between the tip of your nose and the point of your chin. Make sure not to measure under the chin as the Breathe99 Mask is not designed to wrap below the chin.

Breathe99 sizing table

Verify Fit

Ensure that your nose to chin measurement is within the range shown on the table above. The bottom strap of the Breathe99 Overlay, which fastens around the back of the neck, has a maximum circumference of 21 inches (53 cm).

Face Shape & Fit

Compact Fit

The Breathe99 Mask has a flexible facepiece that conforms to your face to form a seal. It is normal to take a few days of use for the facepiece to break in and achieve the best position for sealing.

Adjustment and Seal

The Breathe99 Mask is designed to sit low on the bridge of your nose. If you have a prominent or low nose bridge, you can flip the inner seal up achieve a tighter fit.

How often do I need to change my Breathe99 filters?

Please see the Use & Care tab for when to change your filters, based on what you use them for.

What materials is the Breathe99 Mask made of?


FDA-compliant TPU and Polypropylene


Body: 84% Nylon 16% Spandex, Binding:  92% Nylon 8% Spandex, Stabilizer and Strap: UBL 89% Nylon, 11% Spandex


Meltblown and Electrostatically-charged polypropylene 

How breathable is the Breathe99 Mask?

Breathe99 Mask is very breathable for a respirator or face mask. However, it will not be as comfortable as wearing no mask at all. Breathe99 Mask exceeds the recommended breathing resistance required by NIOSH for Filtering Facepiece Respirators. Light breathing (walking, desk work, driving) through Breathe99 Mask will feel easier than heavy breathing (long flights of stairs, hard labor).

Always taking care.

Stay safe and stress free with easy filter changes and cleaning.

Filter Changes

For a person who only has occasional contact with the public, and can stay physically distanced, we recommend:

  • Change filters at least every 2 weeks.

You should change your filters more often if:

  • You interact daily with the general public, such as for a job
  • You or someone you care for is immunocompromised
  • Your filters get wet while in use
  • Your think your filters may be contaminated

These are guidelines only, as you know your personal situation and risk level best. Please note that no mask can eliminate the breathing in of all particles or the possibility of getting sick. We have previously stated that our filters can be used for unlimited wear time, but felt that did not adequately account for the pandemic-time risk of contamination or degradation due to humidity.


The facepiece, filter caps, and fabric overlay may be washed by hand using a mild soap or detergent. Alternatively, you can place them all in a laundry delicates bag and machine-wash them on the delicates cycle in cold water.


When not in use, the Breathe99 Mask can be folded in half with the overlay straps used to secure it closed. Alternatively, the mask can be left on a clean surface or hung somewhere that is out of the way. Do not store in a sealed container because this prevents moisture evaporation.

My third color!

Wear this every day to visit my dad in the VA nursing home! And here I am on a flight with tons of unmasked youths…I’m a NOVID!

Thank you for your review! Glad to hear the Breathe99 has been keeping you safe!

Susan Doyle
Yay! They’re back!

I was SO thrilled to find out that the Breathe99 masks were available again and that the replacement covers in different colors were also being sold. (I have the black, and always wanted a blue). This is the mask I feel most confident in when I am in a higher-risk environment like a grocery store or theatre, because of its design and good fit. You really can adjust it so it doesn’t steam up your glasses. And I think it has the bonus of looking great. I’m so glad they kept the blue overlay color, and I like the woven texture. All in all, I’m really happy with my purchase. I think it’s well worth the investment. Replacement parts were easy to order and arrived very quickly. Finally, I do like the fact that this product is made in the USA, and designed to be more sustainable over time. Thanks!

Thank you for your kind words! We're so glad you're enjoying the Breathe99 masks - they're perfect for high-risk environments like grocery stores and theaters. The blue overlay color is really popular, and we love the woven texture of the mask. The mask is made in the USA and is designed to be more sustainable over time. We're glad to hear that the replacement parts were easy to order and arrived quickly. Thanks for your positive review!

happy to finally get new covers!!

We got Breathe 99 masks back in May of 2021 -- and joked about how all this was going to be over with the new vaccines. But here we still are. I had already repaired a run in my mask cover as none were available last year. Thrilled to see them back!
I really love this mask. It is easier to get on and off than other "over the head" masks, and it adjusts such over a large size range. I've even worn it with a ski helmet. Added bonus is that it keeps your face warm on cold days

Thank you for your review!

As you noted, the Breathe99 is a great mask balancing comfort with protection!

Good Mask, Looks same as the original so Far

I supported the original Kickstarter for this product, so this was a replacement since the more used of my masks eventually came apart after significant wear and tear over the past ~2 years. I've always been mostly pleased with it since they developed the revised Overlay that really worked for my face (the one it's now sold with regularly). The filters are easy to change out, and I feel like it's kept me mostly safe.
This replacement seem exactly like the original, so I'm happy with it so far and hope it lasts at least as long as my first one.
The only downside I would share is that if you have a really big nose the design can be difficult or not work. I know because I have a "moderately big" we'll say nose and the original overlay (no longer sold) didn't really work that well for me. The new overlay can be adjusted to help that quite a bit. (If they ever come out with the larger size they started to consider making at one point I'd get it, but I suspect that won't happen.)

Thank you so much for your kind words and review!

Additionally, we are glad to hear the new overlay fits well. We are definitely looking into all options with the Breathe99 to see if larger sizes are possible, so stay tuned!

Excellence beyond compare.

These products have literally been glued to my face since the pandemic. Am severely immune compromised and these are effective in safeguarding my health. The Breathe99 masks have allowed me to function normally and are comfortable to wear. Our family enjoys traveling overseas and these are simply the best for those brutally long flights.

We are glad to hear the Breathe 99 masks have been working well for you!

They are definitely a perfect solution to those long airplane and public transit rides.

Breathe99 system fits well.

I've been using the Breathe99 filtration system for 2+ years. The system fits my face very well and is easy to clean and maintain. I believe I'm given superior protection from the various viral and bacterial threats in the world today. The mask doesn't hinder my breathing when I'm working. The replaceable filters are easy to replace and last 2 weeks in everyday use. The ergonomic facepiece and filter caps have not needed replacement and are in great shape. The other components of the system last about 1 year each, i.e., overlay, foam liners, cord lock. The entire system is serviceable and Armbrust offers replacements for all pieces of the system.

Thank you for your review and kind words!

We are proud to provide the Breathe99 system with its protection and ease of use!
