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.

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.

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.

Comfortable, easy to clean and effective.

I bought 2 of these in the early days of the pandemic from the original company that created them and we found them comfortable and they seal well (we both wear glasses so no fogging!). I have a small face (I’m 4’11”) and even though my husband is 6’1” and has a larger face, we both are able to get a good fit. I found that I needed to move the mask around a little to get it sealed just right after adjusting the straps. Though, we still have the original black overlay which is a little different. They are easy to clean and the filters are fairly simple to change out. Neither of us contracted Covid or Flu wearing these, but we did avoid crowded, indoor areas. You can get a little sweaty if wearing it awhile, but adding the foam liners helped a bit (you could probably just add some cotton if necessary). That tends to happen with many types of multi-layer masks. I have also used them for wildfire smoke on the west coast and they really helped! We may have to upgrade to the more attractive overlays :)

Best Fit, Great Filtration, Low Waste

The Breathe99 is BY FAR the most comfortable, best fitting, and most attractive high filtration mask I have used to date for my smaller face/nose. I'm using these in an occupational setting for 8+ hours per day, replacing 3M Aura disposable N95 masks. The only minor issue has been condensation accumulation at the lower lip inside the elastomeric housing - solved easily with placement of a small patch of absorbent cotton in that region. I would love to see these get full FDA and NIOSH approval, it should be a top priority for the company. Excellent design!

Ikoi Hiroe
Great idea, needs better fit

I love the idea but I'd like some way to improve the fit at the top. Flipping the seal is a very short term solution as it tends to slide after a while from the moisture building up

Grace Gausman
Comfy, and reusable

I really like the idea of reusable AND that it has a comfortable neck cord. However, most importantly, it filters 0.1nm particles which covers the Covid sized Virus, without the pooching on sides so theres no leakage!,

Thank you for your review! We are glad the Breathe99 is fitting comfortably and keeping you safe!

Pieter Lechner
Great mask with issues for me

Like some other reviewers I experienced some leaks at the top of the mask when I first put it on. I can eliminate them by tightening the adjustable straps (a very nice feature). But that makes it a little too tight for wearing for extended periods of time. I should add that having tried 13 different N95s it's clear that I have difficulty getting a great seal with any mask. Filtration is something that can be measured (thanks Lloyd for all your efforts) but fit is not without a formal fit test. There is unfortunately no way to know for sure how well a mask will fit without trying it on. And even then you can only approximate how much leakage you are getting. But it is a very nice mask and if it fits you well it should provide good protection while looking good as well.

Thank you for your review and thorough input! Yes fit is indeed important and can be tricky to get perfectly. That is why we have such a thorough FAQ with the Breathe99 mask that helps quite a bit to ensure the mask fits comfortably and properly!

Love it

Wish it would fold and fit in pocket

Thank you for your review and feedback! We will definitely keep this in mind.

I'm in it for the Long Haul

I haven't worn it much yet. I go on a flight next week and intend to wear it. Plus I want to wear it on high pollen count days. I assume it's good for pollen too?

I'm all in on the reusable concept.

Thank you for your review! With the level of filtration, this mask works well for those high pollen days too!

Rebecca Harris
Great mask!

Fits so comfortably, it can be worn for hours! Looking forward to using it for air travel.

Thank you for your review!

The right stuff

It was easy to put together. The adjustable tie is a plus, because sometimes I want to put it on over a wool hat. It’s easy to breathe through. No appreciable resistance. The fit feels a bit weird at first because the bottom is between the chin and lower lip instead of the usual over the chin fit. It still works and I got used to it. The flexible seal is especially large, which makes it comfortable. It seals well, but I generally have to tweak the nose clip and shift it to get it right.

Once I have it on I almost don’t feel it. It does stick out into the bottom of my field of vision, and that takes some getting used to.

The cloth cover is less obtrusive than a white N95 disposable, although the shape of the whole assembly is a bit space age.

I’m glad I bought it.

Thank you for your comprehensive review!
