Common Mask Complaints Solved

Comfort & Breathability

Unicorn ASTM F3502 Masks offer High Performance breathability at 5.9mm h2o tested to the new ASTM F3502 standard. The lower the score, the more breathable. Our CDC recognized ASTM F3502 masks allow up to 15mm h2o (the higher the rating, the more difficult to breathe). NIOSH certified respirators have two different breathability limits: one for inhalation, the other for exhalation. For inhalation the air flow resistance (breathability) for N95s is ≈ 35mm h20, more than double the maximum breathability resistance allowed under the new ASTM F3502 standard!

Unicorn Masks provide Comfort & Breathability.

6 Adjustment Points Solving Gaps & Leakage

Did you know that respiratory aerosols can accumulate the same way cigarette smoke accumulates, in a plume, allowing virus particles to linger up to 16hrs in a low ventilated room?


Featuring up to 6 size options ranging from adults to kids, with a total of 6 adjustment points in a contour design, gaps and leakage are significantly reduced, preventing these particulates as small as 0.1 microns from being inhaled. Most face masks on the market are a 'one-size-fits-most' or offer 2 adult sizes with only 1-2 adjustment points, leaving numerous gaps and leakage, reducing mask particle efficiency up to 60%!

Style & Fit

Unique design elements solving the common complaints of mask wearing.

"As a biomedical engineer scientist with focused research on nanotechnology for regenerative and translational medicine, I endorse the use of nanotechnology utilized by Unicorn Breathing Mask, specifically with the use of electrospinning nanofiber polymers to filter out particulates down to the 0.1 um dimension. This is crucial when providing effective filters for a breathable face mask as a barrier towards viruses like that of the coronavirus. This mask is capable of protecting one from viral particulates exposure due to its robust electrospun nanofiber innovation and recommended 3-ply construction."

Filter Protection

ASTM F3502 Highly Breathable Protection Masks

Award-Winning Nanotechnology Innovation

Face Masks remain the best defense against this and future pandemics including flus and natural disasters, however not all masks are created equal, and we must look ahead to safe and innovative technologies that will solve the concerns of long-term mask wearing. Previous masks have relied on protection basics such as 2-3 ply fabrics, and the use of spunbound or meltblown non-woven polypropylene or other synthetic woven filtration or antibacterial barriers for particle efficiency. However questions as to the overall consumer safety, comfort, breathability and protection over a masks lifespan is of grave concern, particularly in our more vulnerable demographic of kids, seniors and those with respiratory conditions or chemical sensitivities. 

Unicorn 3-ply reusable ASTM F3502-21 Level 2 Masks. High-Performance Barrier Face Coverings. Each wafer-thin replaceable mask filter contains 15 miles of proprietary sonic electrospun nanofiber matrix thousands of times thinner than a human hair, capturing particles as small as PM0.1  at 99% efficiency. Standard mask filters only protect down to PM2.5.

Unicorn Breathing Mask's wafer-thin HIGHLY BREATHABLE CARBON-FREE replaceable filter contains 15+ miles of non-toxic proprietary sonic electrospun nanofiber matrix thousands of times thinner than a human hair, capturing particles as small as PM0.1 with 99% efficiencyStandard reusable mask filters only protect down to PM2.5. Unicorn Masks have a superior lab tested high performance breathability rating of 5.9mm. The highest (meaning least breathable) score permitted for F3502 is 15mm. NIOSH-certified respirators have two different breathability limits: one for inhalation and one for exhalation. For inhalation, the air flow resistance (breathability rating) for N95s is 35mm, more than double the maximum breathability resistance allowed under the new ASTM F3502 standard. Our filters are proving to have many benefits as endorsed by leading bioscientists, with its nanometer fiber diameter resulting in higher fiber surface area, reusability while maintaining electrostatic attraction, higher breathability with great thermal comfort (dramatically reducing any moisture build up), sustainable production efficiency at a lower temperature, and ease of fabricating from a wide selection of materials as opposed to limited thermoplastic polymers.

Filter Safety

Is your filter safe, and will it fiber shed? How is it different from 'nano fabric' masks?


We utilize a very different technology from reusable 'nano fabric' masks. In fact we strongly advise against the use of woven 'nano particles' in textiles, especially when combined with 'antibacterial' silver, copper or zinc particles for health reasons. We also do not endorse the use of carbon commonly found in PM 2.5 filters for mask filtration. Finally, we STRONGLY DISCOURAGE reusable cloth masks that have nanofiber sewn-in to the mask. Antibacterials, metal additives and carbon can actually be harmful to your lung health when worn for extended periods of time and breathed deep into your lungs. And nanofibers CANNOT be washed, without dangerous fiber shedding occuring. Once these nano sized fibers are inhaled, the lungs will not expel them out, due to their small 'nano' size. These nano fabric textiles often come from China and South Korea. BUYER BEWARE of any company selling a sewn-in nanofiber layer into their cloth reusable mask in an attempt to increase particle efficiency! These have not been adequately tested for fiber shedding and are not safe, especially for children's sensitive lungs. Regardless of any press endorsements, marketed particle efficiency, or claims they are making, you must educate yourself on the dangers of wearing any washable filter that has not undergone extensive fiber shedding lab testing that you can visibly see and request. Mold and bacteria issues are also very common with washable filter masks. 


Unicorn masks on the other hand utilize non-woven sonic electrospun nanotechnology (as opposed to a nano embedded woven textile). Being a continuous fiber and not anything related to nanoparticles, there is zero risk of inhalation of anything harmful. The nano fibers are encapsulated by two substrate layers of polypropylene further protecting against any possible fiber shedding. Our filters are manufactured by a leading global nanotechnology company out of New Zealand that is committed to health and safety. Our technology tests down to a much smaller particle size with greater efficiency ratings than nano textiles, and features dramatically higher breathability, greater thermal comfort (far less moisture buildup) and is much more lightweight (less than 1mm thick) than nano textiles. We encourage you to do your own research with all filtered mask companies and note the differences in verified USA lab tested results. The proof is in the pudding as they say! Learn of the toxic nanoplastics and pollutants recently uncovered by bioscientists in disposable masks here. This is one of the many reasons why we DO NOT recommend N95, KN95, surgical, or washable nanofabric embedded masks. 

How do F3502 masks compare with K(N95)/surgicals?

As a point of comparison with other nanofiber masks, ASTM masks (Level 1, 2 and 3) that are tested to the medical F2100-11 standard can often be confused with ASTM F3502-11 masks. The ASTM F2100 standard tests the filter material only as opposed to the whole mask (and is therefore not as thorough or accurate in terms of actual protection), using different sized particles to measure filtration efficiency than the F3502-21 test. The velocity, distance, speed and polarity of the particles are all different, resulting in a less rigorous challenge. In layman's terms the F2100 test is like an underhand softball pitch, whereas the F3502 test could be compared to a major league baseball pitch. F3502 testing uses a similar testing modality as NIOSH respirators, the Sodium Chloride Aerosol Challenge (NaCl), evaluating particle penetration and air flow resistance properties. When looking for a protection mask you want to look for a standard that tests the whole mask when worn, instead of just the filtration, to determine actual efficiency once leakage occurs around the filtration upon wearing. The ASTM F3502 standard is the only standard that takes a four-prong approach addressing the most critical aspects of mask wearing, including particle efficiency, breathability, fit/leakage and material safety/toxicity. It's important to note when searching for ASTM F3502 masks that you search for 'ASTM F3502' specifically. There are very few of us out there! 

Why do you use Electrospun Nanotechnology instead of Meltblown filters found in N95 and surgical masks?

The following graphic demonstrates the CO₂ emission mechanism for both Meltblown and Electrospun nanotechnology filters. It can be observed that Meltblown filters exhibit poor emission as compared to electrospun nanotechnology filters. Recently, a survey reported on the risk of headaches to healthcare providers from wearing N95 face masks.[1]* They concluded that this is due to higher humidity levels, breath resistance, and accumulation of heat inside the micro-climate of the masks. Researchers found that Meltblown N95 masks provide a favourable environment for viruses and bacteria due to its moisture-loving nature.[2] On the other hand, electrospun nanotechnology filters have a finer structure and more uniform morphology and pore diameter. This allows the water vapour to be passed through the filter more consistently and efficiently. This is one of the many reasons why we have chosen Sonic Electrospun Nanotechnology to replace traditional Meltblown filters.

Is UNICORN approved for use in schools?

Yes! We are on the CDC and NIOSH PPE 'Masks That Meet a Standard' Approved Conforming BFCs list accessed via the CDC website here. We are not considered a 'cloth mask,' but rather an ASTM F3502 High Performance Barrier Face Covering utilizing Nanotechnology. If your school takes issue with you wearing our mask because it has a cloth exterior, you can point them to this link found on the CDC.gov website and let them know that our mask has been approved and is currently recommended by the CDC. Unfortunately the new ASTM F3502 Face Barrier Covering standard and use of nanotechnology is very new, and many press/media outlets have not discovered it yet. We are hoping that soon changes!

Mask Comparison

Did You Know?

Our oceans were contaminated with an estimated 1.56 billion disposable, non-biodegradable face masks in 2020 based on a report released by marine conservation organization OceansAsia. This resulted in an additional 4,680 to 6,240 metric tons of marine plastic pollution as evidenced in a report entitled “Masks on the Beach: The Impact of COVID-19 on Marine Plastic Pollution.” These masks will take as long as 450 years to break down, slowly turning into micro plastics that fish and ultimately humans will consume, while negatively impacting marine wildlife and ecosystems. We aim to fix that.

Designed With The Environment In Mind

Our use of certified organic, sustainable inner and exterior fabrics and plant-dyes that come from conscientious countries that don’t spray their fabrics with toxic chemicals, is also a key differentiating factor that stands us apart.

The initial feedback we have received regarding comfort and fit is highly promising. In many cases essential workers forget they are wearing a mask after extended use! Foggy glasses are greatly reduced or eliminated, there were zero reported cases of claustrophobia or difficulty breathing, masks fit comfortably and snugly over facial hair without gaps, there is no slippage with strenuous activity, no sucking in of fabric when exerting heavily or talking, and there are zero reported cases of acne or skin chafing over 12 months of continual daily use up to 8hrs/day, 5 days/week. With a minimum lifespan of 25 washes, our masks are devoted to being a part of the Solution, saving our oceans and eliminating plastic waste. 

Discover how our plant-dyes are handmade

We are a women-owned company based in Studio City, CA, and all masks are lovingly hand-sewn by master craftswomen in Bali. Recently the American Federation of Teachers has entrusted us to outfit their employees. Kids heading back to school love the masks as they are comfortable, breathable and fit snugly, so they are not tempted to pull them down. Kids are also more sensitive to chemicals, making the high thread count undyed, unbleached, raw certified organic cotton interior highly favorable to their sensitive skin. We are a 100% transparent company and proudly display our lab testing on our website, so you don't have to track us down and ask! We also have a dedicated US based Live Chat Customer Service team standing by 6 days/week M-S, 17hrs/day to answer any questions. 


Simply put. WE CARE. A lot.

Hands down - the BEST

After 18 or so long months of wearing masks, looking for masks, fitting masks, and generally having a huge assortment of masks for my children and family to choose from, we have found our Unicorn. My teenage son raves about this mask. 


It’s comfortable for all day use? Check. Doesn’t let his glasses fog up? Check. Lets him breathe and be heard when speaking? Check. *Looks cool* and doesn’t look like he just preformed surgery? Check! 


He’s had school staff ask about it and he is always sharing the website! My preschooler raves about it! He can put it on without help, he is comfortable with it all day long, he loves that he matches his big brother, and he loves that they are soft (yet still hold their shape) and not scratchy. My husband and I rave about them too! FINALLY a mask that FITS our kids! Finally something that they can use in comfort all day long, and something that will keep them safe! Love love love love LOVE our Unicorn masks!!! We will be purchasing adult masks for ourselves as well. Huge hit with this family!


*THANK YOU* to the creators of the Unicorn Breathing Mask, and thank you to the people who are working tirelessly to sew and fabricate these! We appreciate you!

Comfortable

Have also found these useful while cycling. Provide warmth against winter winds as well as protection against dust while farmers are harvedting.

Fantastic mask

Love the fit-better than any other mask I have tried. Very comfortable. Love the many layers of fabric and filters. Breathing is excellent compared to N95s. Will always wear and keep a supply on hand.

Feels protective

This mask is best fit I have found…and I have tried quite a few!

Only negative is the filters are a little fiddly to get in.

Great fit!

Just like the first Unicorn mask I purchased, this one fits like a glove. No fogged glasses and difficulty breathing. I almost forget I'm wearing it.

XL Sport

Great product. Works well, comfortable, efficient and durable

Pretty

The masks are comfy to wear, and I love the unicorn design. Getting the filters into the mask is somewhat of a challenge.

This mask is very comfortable

This mask is very comfortable & I feel safe and protected by it.

fabulous masks

These are the best masks we' ve used in the last two years. Perfect fit, easy to replace filters and fit perfectly into a pocket or purse.

Great as always

Excellent overall design and comfort. Have worn these on planes and other crowded places. So far, so good! (I’m also backed and boosted; you need it all) Now have 15 for a family of 3, seems like the right amount

Only Unicorn Breathing Masks for Me!

I have been using only Unicorn Breathing masks throughout the pandemic. I have many of the styles and this is my 7th mask. It is very comfortable. The bottom line is, I am 75 years old and I have not been sick at all in the past 1 1/2 years. I attribute this to precautions I have taken which include using my Unicorn Breathing masks.

So good ordered a second one

Loved the first one so much that I ordered a second one for my wife! The fit is very good for a reusable mask, the nose clip is starting to show some wear in it of not as stiff but still functional, the chin cover is also showing some wear but is still functional. I feel comfortable wearing it and washing it and changing the filters is simple.

Despite the two cloth layers + filter it is no more difficult to breathe through than a surgical mask - which I wear all day at work. The under the chin portion makes the mask more secure than others. Overall I feel extremely safe wearing this mask.

Perfect

Finally, a mask that fits my face and provides both comfort and protection. I love being able to order different sizes for various family members. They're easy to put on, comfortable, don't fog my glasses and dry overnight when I wash them. Perfect!

Great fit and comfort

It has been difficult to find a mask that fits well, breathable while offering good protection, and is comfortable. These masks are fabulous. Although a little pricey, you are getting great quality.

Classic

These masks are wonderful. I have converted three families to only use these masks. They are easy to clean, and once you get used to putting the filters in it takes no time at all. We use them in all types of weather and the fit is great. My children have no issues with their ears and no gaps

Form & Function

This is the only mask I’ll wear! It’s beautiful, so comfortable and works great! My family and I went to Universal Studios and didn’t get Covid. The masks were breathable even in 80 degree heat. I highly recommend them!

Comfortable

Comfortable but a little pricey. Met my expectations. Would recommend.

We love them

My kids love these masks- they are easy to breathe through. Most importantly, they fit extremely well and do not bother your ears during a long day. I love the ASTM certification. The only thing I wish was different is the ability to replace the bar across the nose when it eventually wears out and breaks.

Fits well

This mask fits me quite well! It took a bit of time to adjust the nose wire so it wouldn't fog up my glasses, but that's to be expected. Like that the stiffness of the mask keeps it from touching my mouth.

Looks great

As far as masks go, this one looks great on my husband. We feel good about the 3-ply and it is very comfortable.

good protection, well-made

I'd purchased one previously, and at first had more difficulty breathing, but then I realized I was comparing to the more porous cloth masks. Now that I am used to this, and 3 layer masks with filters, this is not a problem. Especially with case numbers so high, I wear this new one (blue hemp) and previous one (linen) exclusively when going out. It is nice knowing the mask/filter has been so well researched and designed for top protection in all the details, and with attention to sustainability. Originally I found the filters hard to insert, but now seem to have the knack and this really isn't a problem. Plus they're attractive, not flashy but fine, and in fact have had strangers comment on it and ask where to get one!

GREAT MASK

LOVE my Unicorn mask! Fits very well, Easy to put on, Easy to breathe through

Great maxes

It doesn’t get hot, you can breathe very well. Comfortable. Love that way I have bought 5. Thanks so much for making this great maxes.

Looks Great!

Honestly haven’t used them yet, saving them for my travels for my upcoming honeymoon. But they feel soft and look cool and the filters look good. Thank you!

A breath of fresh air - literally!

I have bought Unicorn masks for a handful of loved ones and I have recommended your masks to all that I know. Your masks stand above and beyond the others. We love our masks, they are great quality and fit. We feel confident and comfortable.Thank you very much for your very thoughtful and protective masks! It’s a breath of fresh air literally! Just make sure to check the sizing tab for best fit.
