This fits a big nose

Don't laugh. I've been having a hard time finding a mask that fits my big nose. Think Romanesque nose. (Look it up if you have to.) My big Romanesque nose is not a wide flat nose. It's different. The problem I've had is other masks leave a sizable gap below my eyes so I'm breathing into my eyeballs. (Stop laughing!) Even those aftermarket aluminum strips to help shape the mask didn't work. They have no real strength to hold tight. It's been really frustrating this past Covid year-and-a half. HOWEVER - THIS MASK FITS!!!! Aside from the size being good, the metal bar is just strong enough to hold it's shape. I'm not breathing though my eyes any longer. I'd like to see the bar a bit stronger, but this is just good enough. As for the filter ratings, I have to take that on faith. Still, I'm breathing THROUGH the mask now, not around it.

no gaps

I have a small face so I have had problems finding a mask that doesn't gap, especially under the chin. This is a mask that fits and is still adjustable.

Terrific Masks

My husband and I love these masks. We love that they're organic so you're not breathing chemicals all day. They fit very well with no gaps anywhere. The bendable noseband works much better than other masks we have. Great product!!

Fits phenomenally on my face very comfortable.

comfortable, glasses don't fog

I've only worn it once so far. I had a hard time trying to get the filters in and straightened out.
So far, it's very comfortable.

Love these masks!

I purchased these for my twin 12 year olds when they were going back to school. They say that they can breathe in these masks better than any other ones we tried (even when playing sports). I feel confident in the protection with the masks. And bonus, my daughter wears glasses and these are the only masks that don’t fog up her glasses.

Great masks!

I own close to a dozen different masks and these are by far the best. They are the most comfortable and I love that there is a gap inside the mask between your face and the fabric that makes you feel less smothered.


A protective mask that is comfortable, adjustable, easy on and off, doesn't slide down under your nose and can be worn with hearing aids! Love the unicorn embroidered on the mask too.

Good fitting

I love the material and the stylish look. I love the feel of it and that you can add filters to upgrade its efficiency. What I really love is that it is snug fitting all around especially at the chin. I play table tennis and and also happy it doesn't fog up my glasses like some others but still feels breathable. I was also trying to decide about what size would be best. I opted for the medium even though I have a smaller face. It fits fine, but had I gone with the 'small', I imagine my grandkids might have had gotten a new mask as it probably would have been too small for me. A bit pricey but am very happy with the quality and fit! 👍

Feel secure

This mask is stylish, well made and well fitted. My glasses no longer fog up.

Very pleased

I’ve struggled to find a mask that fits, as I’m on the petite side and most adult masks swamp me. However, I’m a teacher, and after a number of our staff got Covid this school year (despite being vaccinated), I knew I needed to up my mask game. I’m just sad I didn't get these sooner. IT FITS. I really didn’t think it was possible to find a mask that does! It’s a secure fit but comfortable, and I can easily speak in it to my classes. I don’t love that I have to hand wash or that the filters are fiddly, but any annoyance there is outweighed by what a pleasure they are to wear. Plus I simply feel safer at school.

Unicorn heart mask

Very pleased with my purchase. This mask is well made and I appreciate the layers, etc. I am very picky about what masks I buy. They must meet certain standards as I am immune compromised. I was impressed with the washing and care instructions. I haven't worn it yet but I pretty sure I will be a repeat buyer.

Finally found one!!!

I have searched far and wide for a mask that I can tolerate. I have literally bought ten or more different high-end, supposedly non-toxic masks. All of them gave me breathing problems, many hours after removing. There are too many toxic chemicals in most filters. The filters made by Unicorn are truly unique. I have worn my mask 5-6 times now and had no problems. I had given up looking for a safe mask and then I stumbled across the Unicorn breathing mask. I bought the organic, white hemp mask. I just ordered three more. I think they are a bit pricey and high-maintenance, but will gladly accept these things to breathe again!!! Many thanks to Sky and all dedicated to helping people like me. By the way I am very petite (90#) but as recommended by Sky, the adult medium fits fine. Go ahead and buy one. My only regret is not having these masks back when the pandemic started.

By far the best company I have dealt with

A huge THANK YOU to the team at Unicorn Breathing Masks for going out of your way to make sure our new masks arrived in time for us to wear to our family wedding over the weekend. You guys are by far the best company I have dealt with in many years. I was afraid our masks wouldn’t get here in time you guys upgraded our order to priority shipping and our masks arrived in time for us to wash and wear them to the wedding. We love our new masks, they are comfortable as well as effective. Thank you for such a great product and great customer service.

(Attached is a picture of us in our masks at the wedding. We love how nice they look even in a formal setting.)

Sincere thanks!
Melissa and family

Comfortablw, fits well, EZ to breath

This mask is comfortable and fits well. As an asthmatic, it's one of the few masks that doesn't aggravate my breathing. I'm 6 feet tall and 210 lbs with a beard, and the xl mask fits great with a good seal that doesn't fog up my glasses.

Great masks!

Very comfortable and a snug fit. Highly recommend.

very comfortable and breathable

The mask and filters are lightweight and very easy to tolerate. Very easy to breathe through. Good fit. very pleased with the purchase.

Unicorn mask

Excellent material and design. Shared with ICU staff as a thank you for all their hard work over the last 19 months. Everyone loves these mask.

Best Masks

These are wonderful masks! They're comfortable, they provide a great fit, and they don't fog up glasses as most other masks do. They are easy to breath in, and they don't get stuck to your face when talking. They also meet the ASTM F3502 standard. I ordered 6 and they arrived very quickly. Well worth the price!


This Unicorn mask is a perfect fit and, best of all, does not fog up my glasses. Filter is easy to replace, and the material easy to wash and dry. Thank you for this design that provides good protection.

So good!

The masks fit well - from my 3 yo to us adults - we can adjust for a snug fit. Easy breathing and love the included filter!

Husband liked it!

Got this for my husband and he was impressed with the fit, quality and comfort. Thanks for such a great product!

Comfy and fits well!

Probably the most comfortable mask I’ve worn and the fit is perfect! I feel protected! Easy to breathe too.

Great fitting mask

This is the best fitting mask that I’ve used so far. Very comfortable to wear and a good price! Highly recommend!
