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, while the filter inserts use a fraction of the polypropylene meltblown media used in traditional disposable masks. This combination makes the Breathe99 system far more sustainable, reducing non-biodegradable waste by more than 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.

Comfy & Protective

While it looks pretty bulky on my small face it is worth the money. It forms a good seal and has felt quite protective. Very easy to clean and replace filters. I switch between this one, N95s and KN95s generally. Also doesn’t look to bad and I like the adjustability.

Hi Sasha! We are so happy that you are loving your Breathe99 mask and we appreciate your review!

Wish I’d had this sooner!

Now that so many folks no longer care about Covid, I find this mask ann indispensable addition to life. I was using N95s before, but the fit of these was never optimal, Ann’si was always quietly worried. This Breathe99 mask fits much more securely (even with my rather pronounced nose)! I feel a zillion times safer indoors around people without masks on now :)

Hi Elise! We are so happy to hear that you are loving the fit of your Breathe99 mask and truly appreciate your support and feedback!

what happened to the breathe99 lighter-weight overlay?

I like my mask but in warm weather I prefer the lighter black mesh overlay style. I do not see it offered anymore and wonder what happened? bring it back please!

Eric Goodspeed
Breathe Long and Prosper

Reporting from the medical field and having tried numerous other disposable and reusable mask systems, I find that the Breathe99 is a superiorly designed and functioning mask. It is compact, light, good looking and durable. The mask is easily carried when not worn. To date, since my first Breathe99 usage in early 2021, my practical real world n = 1 experiment has proven to be effective.

Thank you so much for your thorough review! We are proud to provide a mask as quality as the Breathe99.

Deborah Alexander
Feel secure on public transportation

The mask is comfortable also. However, I don’t think I’ll use it in warmer weather. The area that covers the nose and mouth feel like rubber and will be too hot.

Hi Deborah! We are so happy that you are finding your Breathe99 mask to be comfortable! We do offer foam liners for the mask that can help with moisture build up during those warm/summer months!

Really, really like this mask

This is an excellent purchase. The mask is effective, sealing well while remaining comfortable, and is neat and low-profile for an elastomeric. I love that the straps go around the back of the head and not over the ears - much more comfortable when wearing for any length of time - and the environmental benefits of just switching out small filters and not throwing the whole mask away each time are also appealing. I've been using this as my go-to mask for some time now and I am completely satisfied with it in all aspects - highly recommended.

Hi Kathryn! We are so happy that you are loving your Breathe99 mask and we appreciate your review!

For concerts and plane travel

I purchased this mask as an upgrade from the typical N-95-style mask to attend indoor concerts and for airplane travel.
It fights very well and looks sharp!

Hi Casey! We are so happy that you are loving the fit and looks of your Breathe99 mask and truly appreciate your support!

Thumbs up

At frist i though it didnt fit since the length hit egde of my chin give or take a few cm. However i think suppose fit like that. It's comfortable, breathable and nice looking. Dont know about you but i definetly look cool in mine. Kidding aside. I wanted to invest in a daily mask. This may be the ticket. The only confusing part is in video show him placing the white part filter outwards but the direction came with say box saysplace color part facing outwards, which i did. Fit is snug as want to be as you can adjust cords. I tie end loop so doesnt slide out in back. I really dont give 5 stars out anything, just saying.

Hello and thank you for your review! We are so happy that you are loving the fit and look of the Breathe99 mask! For reference on inserting the filters, the filters should be inserted printed or colored side out!
