How do I clean my mask? What detergent should I use?

Please be sure to hand-wash your mask before wearing for the first time. We recommend using a natural or organic liquid detergent in warm water.

  1. Remove filters before washing.
  2. Add a small amount of natural liquid detergent to warm water.
  3. Submerge and massage mask thoroughly for 30 sec. Soak for 10-15 min.
  4. Rinse well under faucet or in clean water. 
  5. Ring out excess water. Be careful not to over bend the noseband.
  6. Hang dry. Direct sunlight preferable to sanitize. Add filters once dry.

Do not machine wash or machine dry as this may distort the shape or clog the mask fibers with dirt, impurities and minerals in the water, causing it to be less effective over time. Always remove the filters before washing. NEVER submerge the filters in water or attempt to clean! Once mask is completely dry, insert the filters one on each side and you’re ready to go! We always suggest purchasing at least two masks in order to have a fresh mask readily available, especially if you are an essential worker.

Why can't I throw my mask in a front loading machine on gentle cycle?

Advanced protection masks cannot be washed due to the loss of electrostatic attraction/protection, as well as loss of shape/form that alters fit upon washing, and therefore the loss of particle filtration efficiency. This is why most advanced protection masks are throwaways, which is very hard on our environment and our pocketbooks for the life of a pandemic. Hence why we created the world's first maximum protection cloth reusable mask! We always suggest having a 'wash party' where you blast your music, enjoy your favorite beverage and wash all but one at once, then sun dry. This way you have enough clean masks for the month! We suggest purchasing at least four masks in order to have a fresh supply on the ready, especially if you are an essential worker. :) Be sure to always remove filters upon washing! They must be discarded if they get wet!

How long do masks last?

Each mask lasts approximately 6 months dependent upon use and care. 

Why doesn’t this mask have an exhale valve?

Due to the superior and efficient nanofilter technology and outstanding breathability, our masks do not require an exhale valve. Please consider exercising in masks at your own risk. We do have professional athletes who use our mask but do not assume any liability for any injuries that can occur. Note that some cities have banned valve masks due to exhaled air passing unfiltered, taking potential coronavirus droplets with it.

Do you offer custom masks for companies or bulk orders?

Yes! We offer custom embroidery and fabric options for bulk orders. Currently we can accommodate orders up to 500k/month. Orders exceeding 500k can be ramped up with a 90 day lead time. We do offer special discounted pricing for government, essential worker, and educator contracts, above and beyond our wholesale pricing. We also offer special discounts for referrals.

Where can I find Shipping Information?

Do you offer Returns, Exchanges, or Refunds?


What happens if my filters accidentally get wet?

You must dispose of any filters that get wet. Otherwise you risk a bacterial infection and loss of filtration efficiency. No exceptions! And this goes for any true protection mask filter!

Do the filters need to be inserted into the mask to achieve the 99% efficiency rating?

Yes! The filters are what makes our mask a true protection mask and give it its high rating.

How do I insert the filters properly?

Can I use Unicorn Filters in other mask brands?

Our filters are designed specifically for the Unicorn Mask and we do not recommend inserting them into different mask brands as it will drastically reduce the efficiency rating.

How is this mask filter different from 'nano fabric'?

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 'nano' 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. These nano fabric textiles often come from China and South Korea. Unicorn masks utilize sonic electrospun nanotechnology in a separate filter (as opposed to a nano embedded textile), which you can read more about on our website. Our filters are manufactured by a leading global nanotechnology company out of New Zealand that is committed to health and safety. They are inert and completely safe for kids, seniors and those with chemical sensitivities. Our technology tests down to a much smaller particle size with greater efficiency ratings than nano textiles. We encourage you to do your own research with all filtered mask companies and choose the company that meets your unique needs. If you would like specific information on our proprietary nanotechnology innovation, please email and we will provide additional reading material that will assist you in your research. 

Does having 2 separate filters (one on each side) instead of one big filter reduce the protection efficiency?

Unicorn Masks have two separate filters, one on each side of the mask, for ease of getting in/out, that covers the entire surface area (minus the thin reinforced stitching centerfold of the mask which nothing can penetrate through) and has the same level of protection and efficiency as if you were to utilize one giant filter. The reason we did this from a design standpoint was due to the plethora of complaints we would hear from consumers of mask companies who had one filter that was incredibly challenging to get in/out. When you're washing your mask on a weekly basis, ease of removing the filters is imperative. We wanted to ensure our particle efficiency wouldn't suffer and were happy to see that it did not. The only part of the mask that is not covered by the filter is the thin reinforced center stitch, which has a thick reinforced stitch that nothing can penetrate through. You can view our particle efficiency lab results here:

How long do filters last?

Each set of filters last approximately 200 hours depending on use and environment. We always recommend that you replace filters after air travel, attending high-risk events, or any time you feel exposure.
