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 reduce non-biodegradable waste therefore being more sustainable.

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.

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.

How often do I need to change my Breathe99 filters?

What materials is the Breathe99 Mask made of?

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.

Stealthy and Healthy

It took me maybe three days of wear to 'break it in' so the nosepiece fit more securely. Super wet inside from condensation so make sure to buy the foam insert. Squeezes my cheeks a bit too hard but I have large cheeks and a round face lol. Also I am prone to breakouts so I have to wipe the silicone with an alcohol wipe every day to get rid of oil build up. I think this was the best purchase I have made for the pandemic, I feel like it is an essential tool in my prevention tool kit. It is so affordable and stealthy for the quality, and the color and weave is so cute. Thank you!!

Hi Sierra! We are so happy that you are loving your Breathe99 mask and we truly appreciate your feedback! Thank you for the support!

Comfy and stylish

Wear this around the office and out and about when shopping or attending crowded events and it feels comfortable. The big test was during a packed week long convention with crowded sessions. Sites revealed many positive cases afterwards but all my tests came back negative. Like mine so much ordered a second for my father.

Only quirk for me is it doesn't quite fit around my nose, but I found some material to stuff up under the rubber so it puffs up a bit and seals better.

Hi Teri! We are so happy that you are loving your Breathe99 mask!

Regarding the fit around your nose - we do suggest flipping that nose piece up and over your nose, pinching to conform and giving the mask 5-7 days of consecutive wear to give the mask a chance to properly conform to your face as this has helped some customer's!

Thanks so much for your support!


I am satisfied, as expected

Hello! We are so happy that you are loving your Breathe99 mask and we appreciate your support!

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!

Laura Thor
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.

Fabulous mask, a bit small

Very nice design, love that it is foldable! It is a little bit on the small size for my face, my only wish is that you make more than one size. I do have to flip the rubber up (as the instructions suggested) to get a good seal at my nose, and it works. It would be great to have some artist-designed fashionable covers for it. A silver sequinned cover for evening wear would be great!

We are so happy that you are loving your Breathe99 mask and we truly appreciate your suggestions! Thank you for your support, Kate!

Larry Rossi
Bought Another!

Such a good product that I bought another for my brother. My doctors were impressed enough to also inquire where to purchase one. Has a very stylish and unimposing look to those no longer wearing a mask, and available in multiple colors for the fashion-conscious.

We are so happy that you are loving your Breathe99 mask, Larry! We appreciate you spreading the word and your support!
