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 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%!

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 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 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 '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. We also do not endorse the use of carbon commonly found in PM 2.5 filters for mask filtration. 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.

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.

These things are great!

A friend recommended these masks to me, and I'm so glad she did! They are super comfortable, easier to breathe in, and come in various sizes. Adjustable straps making them a breeze to adjust. While pricey compared to others, it's well worth the price. You do get what you pay for on these!

Great mask

Quality mask, great fit. Feel really comfortable wearing it knowing all the layers of protection are in place and fit is great. Have four right now. Had compliments about the mask when wearing it. Super customer service. Order was shipped the same day, within a few hours of placing the order.

Excellent Protection

We have purchased a total of 10 of these masks in different colors for work and school. We are very pleased with the comfort and performance of these masks as well as the fast shipping and the company’s transparency about materials, standards, and testing. We are happy to support an ethical company that is providing an important public service. Thank you, Unicorn!

My Favorite Masks!!

Unicorn masks have been my favorites since I discovered them. Have quite a collection now. The sport masks are the most comfortable for me, and all of them wash nicely by hand. Getting the filters back into them is NOT my favorite task, but I feel it's worth it to be protected, and able to wear one all day. I didn't tolerate lots of previous brands very well for extended wearing. My only question is how they compare to the N95s that are currently being suggested for the highest protection. Have tried to read your protection information, but can't make out much of it because it's too small on my phone. Finally, I do recommend these highly for comfort, the very best nose wire, and breathability.

So nice I had to buy twice!

I love this mask so much. My fave. I dropped it somewhere one night and was really bummed so I ordered a new one.

It’s beautiful and the material really sparkles!

The fit is fantastic and I feel so safe wearing it. The transparency on the website for the filter testing brings peace of mind. I highly recommend. I get compliments all the time when I wear this mask.

Best kids mask!!!

My son wouldn't ever try any other mask but the unicorn adjusts well and isn't oversized. My son stopped fighting his unicorn after the first 3 minutes.

Best mask, hands down

The nose-bridge wire is thick enough to stay the way you want it. The under-chin fabric makes a great seal and for once, my glasses don't fog when I am inside (cold weather makes it impossible outside regardless of mask type for my small frames), The mask is comfortable, soft against the skin, and pretty on the outside. I am giving these to friends for small Christmas gifts.

Great fit

I purchased my Unicorn masks based on their high level of protection from virus-containing aerosols. I am very happy with my masks - great fit and work very well in the gym. This is the best fitting mask I've ever used.

I now have 6

I started with two masks, and then I lost one. I was legit devastated because they fit so well. I work in the service industry, and I also work with elders, so I need to make sure I'm never putting the elders at risk. That is how I have ended up with 6 masks. Love them and don't want to be without one in reach.

Rx ya do everyone should own 2 of these. Colors excellent.

I feel much safer with my filtered mask.

Great masks

These are great masks. I bought one for my mom and this is the 4th one I bought for myself. The most comfortable mask I have ever worn!

Best Mask!

Easy to breathe and coverage is exceptional. I would say if you are close to the top of the weight range, order the next size up. i am 126 and needed a large.

The only masks my kids will wear all day

My family loves these masks. They are so breathable and comfortable and doesn't feel like you're suffocating in them. Also the only ones we've tried (and we've tried a lot) that don't suck into your mouth or nose when you breathe.

We previously had the vista print ones but once I purchased these my kids don't want any others. I purchased a few of these for each of us so that we can have them in rotation and I'm not washing like a mad woman every day.

My kids and I are able to keep them on at school all day, and even when playing sports my kids choose to wear them even when they're allowed to remove their masks.

I highly recommend. You can tell that the owners of this company care about the well being and comfort of their customers. Hands down the best masks on the market.

As a parent and educator, I feel safe and comfortable knowing that these filters are legit and the company makes the reports of the filters on their site for customers' info and transparency.

Beautiful, comfortable and effective

I get lots of compliments on my Unicorn masks and I feel safer when I have to go out in the world.

Great mask!

Just purchased my second one. Great mask! Comfortable and fit great. Holds up well to washing too. There is still plenty of life left in the first one I purchased back in the summer. Filters fit well although they can be a little tricky to place into mask. The F3502 rating is what sold me on giving these a try. No disappointment whatsoever.

Best mask

Our whole family has a unicorn mask. Our 9 year old daughter has three and wears one every day at school. Hands down the best mask we’ve found, even before considering the F3502 rating. We have tried lots of masks, including another brand rated for F3502. Don’t wast your time if you’re looking for this rating. You won’t be disappointed with this one.

Best mask ever

This is a comfortable and excellent mask. I like that it has filters and that it cuts low below the eyes so glasses do not fog.

Most comfortable mask I have worn!

With the filters inserted, I am confident I am protected as well as comfortable. The customer service was very helpful when I had a minor problem with one of the masks I purchased. Thank you.

Great fit, great product

Excellent quality. Nice fit. Looks cool.

ICU approved.

Excellent quality. Holds up well. Fits well and is comfortable.
Definitely a mask to purchase and can use daily.

Great Product

I love the mask. It's sturdy and my eyeglasses don't fog from my breath. The filters are easy to insert and remove.

Fits like it was custom-made

My new mask fits like it was made for me! It follows the contours of my face, from across my nose to my ears and under my chin. Very comfortable.
