We offer 3 sizes in the Pro Series and 5 sizes in the Ultra Series to fit many different face shapes and sizes. Please use the Nose Bridge - Chin Measurement chart to help determine what size you should purchase.

Check out our comparison chart to see the differences and see which works for you.

Use the "Filter by Size" feature at the top of the Pro Series and Ultra Series pages to see what masks are available in your size. Please note that not every design is made in all sizes. XS and XL are only available in the Ultra Series.

We only have one medium size, which fits a range of children and adults, depending on face shape and size. Please choose according to the measurement guide for the most accurate sizing.

Our filter has been rigorously tested with labs accredited by the American Association for Laboratory Accreditation (A2LA) to the ISO/IEC 17025 standard. In a NaCl aerosol test report, our masks demonstrate a 98% level of filtration efficacy down to 0.3 microns. The NaCl test is the NIOSH Respirator Prequalification test, and is a widely accepted method for evaluating particle penetration and airflow resistance for N95 masks. Additional testing data can be found on our Technology page. 

N95 masks are made for medical settings and tested by NIOSH, which means they are one-time use, require a fit-test, and provide an extremely tight seal. Happy Masks are designed for non-medical settings, and are washable and reusable with a tested filter. While Happy Masks do not provide as tight of a side-seal as a N95, they provide more than adequate protection in everyday situations, assuming a correct fit. 

We generally launch new designs once every month or two. We also regularly discontinue old or limited edition designs to make room for new ones, so if you see a design you like, be sure to get it while you can! We love to create designs based on customer feedback, so if you have suggestions, please reach out to us at info@happymasks.com. 

Our mask is made up of 5 lightweight layers. The outer and inner layers are made of a moisture-resistant polyester, while the filter is made of 2 layers of non-woven material and a nano-microporous film embedded in between them. The combination of a thin profile with 98% filtering efficiency is what makes our masks uniquely comfortable and protective.

If you're missing an ear adjuster (or two), please just reach out to our customer service team, and we'll be happy to send you a pack of replacement ear adjusters. You'll just pay for shipping.

Our masks typically last approximately 250 hours, or around 2 months of regular use, but this may vary slightly depending on individual environments and wear and tear.

The Ultra Series can withstand machine-washing (preferably on gentle cycle in a mesh bag, and then air-dried) approximately 25 times. The Pro Series must be hand-washed, though, as the spinning cycle of a washer and dryer can compromise the filter. 

For unpleasant odors, we advise washing it using a few drops of hypoallergenic laundry detergent such as Tide Free and Gentle, and then giving it a light spray of 70% isopropyl alcohol on both sides and letting it dry in sunlight. Some of our customers have also had luck with placing the clean, dry mask inside a sealed tupperware container with some peppermint Life Savers! 

We have not changed our sizing, and use a precision laser machine to cut our masks. Except for very slight variations due to the trim being hand-sewn, all masks of the same size have the same dimensions. A brand new mask may sometimes feel differently compared to one that has been washed and worn, as it will naturally soften over time. If you find the stiffness of a new mask to feel uncomfortable or ill-fitting, please wash it a few extra times, which should soften it. If you still have issues, please reach out to us at info@happymasks.com.
