Common Mask Complaints Solved

Comfort & Breathability

Unicorn ASTM Masks offer High Performance breathability at 5mm h2o tested to the new ASTM F3502 standard. The lower the score, the more breathable. ASTM F3502 allows 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%! View our Manufacturer's Design Analysis here.

Unique design elements solving the common complaints of mask wearing.

Unicorn Masks unique design elements solve 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 Workplace 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 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 5mm. 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 'nano fabric' masks you may have come across in your research. In fact we strongly advise against the use of woven 'nano particles' in textiles, especially when combined with 'anti-bacterial' silver or zinc particles for health reasons. These materials have not been tested for use in face coverings and according to several scientific peer-reviewed articles, can actually be harmful to your lung health when worn for extended periods of time due to fiber shedding. Once these 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. 

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!

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.

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 all of our wholesale pricing and 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.

Best Kids Mask on the market

As a very concerned parent with a child who has an autoimmune disorder, I've been tied up in knots with the decision to return back to school in the Fall. A dear friend pointed me to Unicorn and I was able to breathe a big sigh of relief for the first time in over a year. I just received the masks today and was BLOWN AWAY. My 7 year old was able to wear a mask for the first time without having difficulty breathing and it really did fit like a glove as promised. I couldn't be more grateful. The best part? It's not slipping down from the nose or caving in when talking. The fabric design hides dirt and spills. The chin wrap is brilliant. Thank you.

My life depends on it

Being immunocompromised, I need a mask that works. Seriously.

I am so happy with my masks

They are well made, comfortable, I feel safe in them and design wise quite beautiful. I purchased a hemp mask for me and a linen one for my daughter. These are our new go-to (forever) masks. I even wore it when I did exercise. Of course, the most important part is that the masks are ASTM F3502!! What a relief to have this level of protection. And I had an unusual and wonderful customer service experience. I needed to ask a few questions and fortunately, the founder of the company was answering calls for an employee who was out for the day. Well….what an amazing talk that was. Sky is extremely knowledgeable and gave me quite an education. We spoke for 35 minutes!! She is totally passionate and committed to helping people stay safe as well as educate them. And she is a lovely person… so much fun to talk to as well. How lucky was I to connect with her and her great masks.
Thank you, Sky, Roni

Sport mask is the best!!

Throughout this era of masks and face coverings I have tried many. The Unicorn sport mask is now the only one that I will wear. I found it the most comfortable. Its easier to keep my glasses from fogging, and I feel that it is easier to breath.
Thanks Kimberly

Comfortable mask

I use this mask when I go running. It’s comfortable and breathable. The fabric is soft on my face. It doesn’t make me feel like I’m inhaling mask fibers like the disposable masks feel.

Another Happy Repeat Customer from Canada :)

This is my fifth time ordering from Unicorn and every time they deliver. I live in Canada and was so impressed with their turnaround. They literally ship out the masks same day and I've never had a problem with shipping. I can purchase bulk masks direct from their site now which is a major plus. You can't beat the bulk discounts. I highly recommend this company to anyone considering ordering from outside the US. Their day/night Customer Service team is also highly knowledgeable and helpful. Any time I have a question/concern they are there to provide an immediate answer. Rare! Thank you Ms. Sky and Team Unicorn. You're awesome!

Best Fitting

Great fit; actually keeps my glasses from fogging up, and slips under the chin nicely.

Comfortable and Gives Confidence

I received my order of masks and I am extremely happy with the quality.
The packaging was very well done and the fit of the mask is perfect. No air leakage at all upon breathing and the nose adjuster is also a very nice material. It's a softer material that can be shaped perfectly to the bridge of your nose.
The 0.1 micron rating with the changable filters and perfect fit makes me feel much more comforable when I go out in these troubled times.
The provided documentation (for cleaning/etc.) is very well done and appreciated.

Thank you so much for your detailed efforts and keep up the great work.

love these masks

I have a large farm in the Central CA region and my workers need something cooling they can easily breathe through. I got these unicorn embroidered masks for all the ladies in the linen per the recommendation of the service team. They love them. Now the guys want to take them! Kimberly or 'Sky' as they call her is the sweetest lady and really cares. She is passionate about what she does in using organic, safe materials. I don't know why everyone in the world doesn't own one of her masks.

Bulk mask purchase - A+!

I just made a bulk purchase for my employees and am THRILLED at the level of service! I received my masks AHEAD of schedule at an INCREDIBLE price thanks to their economy reopening sale. What I witness is a woman-owned company (thankfully) that truly cares. They most definitely practice what they preach in every facet of what they do, including their exceptional Live Customer Service Team. My employees are grateful that we provided them with such healthy, comfortable and breathable masks. Thank you Ms. Sky and Team Unicorn. As previous reviews have stated, ABOVE & BEYOND.

Mask Review

The mask is vey comfortable. I am happy with it.

Sport mask

No more foggy glasses! Very easy to wear and breath. Love it. Next version needs a flexible lcd panel and AI software to show a mouth moving to my speech! (for under $100)...

Best mask by far

Love this mask. The filter inserts are brilliant. XL fits my enormous schnoz with no problem. Only mask I have tried that keeps my glasses from fogging.

Expensive but well the money

High quality product that comes with two filters
My glasses don’t fog up and my ears are comfortable
This is a great product

LOVE these masks- safe and comfortable for back to school

Since the vaccine for kids will be a while coming, we wanted a really safe mask for our kids to go back to school. This one fits so well. I love that the filters fit ALL of the mask. I love that they have tested the filters to ensure they are effective. And I love that they are made with organic and non-toxic fabrics. My kids love that the mask is really comfortable, and stays off their face so it is easy to breath and talk through. We got adult size M for my 11 and 13 yr old and they fit great!

Love these masks for back to school and sports!!!

We are so happy with these masks. My boys 11 and 13 are back to school for the first time in a year, and we wanted something that felt really safe. I love that the filters fit ALL of the mask. And that the filters are tested to be effective. What my kids love is that they fit comfortably and they don't have to fuss to keep them in place. They stay put, and are easy to breath and talk through. LOVE LOVE LOVE. We got adult size medium and they fit great.

The Best!

Best mask I’ve come across BY FAR! And NOT MADE IN CHINA!

A Happy Teacher! :)

Thank you so much for the great mask and rainbow "love" pin!! To be honest, it is the first mask I have ever worn that wasn't one of those disposable kind. It is so comfortable and doesn't feel suffocating like the other ones do. Also, I love the adjustable straps for behind the ears as well. I am a teacher and when I am in school I have to wear the mask most of the day so I really will appreciate its comfort then. We are out this week and learning remotely because of a spike in Covid but will be returning next week (fingers crossed). Your thoughtfulness is really appreciated.

Great for working out

Masks are required in my gym. Looks great on, easy to breathe, takes care of any extra moisture, can sweat heavily without a problem, great interior fabric, feels healthy.

Cute mask

My 5 year old loves this mask. It makes him happy. I like that it has the same protection filters as the adult mask. I bought two so one can always be available while the other is being washed and air dried.

Well made

Many things I like about this mask but what stands out most is how well made it is, good job.

Love it for Real Estate

Being in real estate I needed to find a professional looking mask that I could perform Open Houses in and also be able to communicate clearly. The mask doesn’t touch my mouth and gives me plenty of room to breathe and speak easily. I also love that the cotton fabric doesn’t get wet when I talk. This is a great mask and I bought one for my entire team with their custom embroidery option. I also appreciated the wholesale prices. Hard to believe you can get a mask of this quality for such a great price! Way to go!

Amazing fit!

Fits secure around my face with no caving in. I’ve been through many masks and Unicorn is the best. I can breathe with comfort and thrilled about protection. Magnifique

Back 2 School

Unicorn kids masks have been invaluable for concerned parents like myself and my husband. I have yet to come across better protection and such a well-fitted mask. It is comfortable for the kids to wear and super easy for them to breathe through. I can actually hear them talk and understand what they’re saying unlike the hundreds of other masks I’ve tried. This mask company is the one to beat. PS. Do you make a mask for dogs? I’ve heard they can catch covid and would be nice to have in congested areas. Bill, Teri & the kiddos, A happy family from TX

Thank you Unicorn and Kimberly Sky

As a nurse this mask meets all the requirements and gives me a little added fashion to bring happiness to my day. I love the flower of life motif and it is just subtle enough to be there with a silver sparkle sheen, but still very professional. The most comfortable mask I’ve ever put on by far and away. I feel very safe in this mask and the test results prove it. Thank you Kimberly.
