Featuring the Protex™ All-Day-Comfort™ System

Shawmut – a world leader in advanced materials – has put everything we know into our Protex™ N95 molded-cup-style respirator, including our patent-pending Protex™ All-Day-Comfort™ System. 

Designed, engineered, and manufactured in Massachusetts, Shawmut’s new Protex™ N95 models are easier to breathe through, as the Protex™ All-Day-Comfort™ System offers a comfortable fit while assuring a tight seal to provide N95 protection across a wide range of face shapes and sizes.

The small Protex™ N95 respirator was skillfully engineered with fit and comfort in mind for smaller faces. It was made with the same design as the M/L N95, but with a smaller form factor to fit smaller faces.

The Protex™ ADC™ System combines a unique soft but strong inner layer, incredibly lightweight but highly efficient and effective inner filtration layer, and high-sealing viscoelastic nose foam for a secure but comfortable seal.

The masks are working well. Of all the masks we have used these are the tightest and best fitting masks of all of them.


Therapy Center, Massachusetts

The cushioning nose foam and the staple free attachment point make the mask extremely comfortable to wear. Having these masks available for our staff has truly given me peace of mind that our facility is protected from the COVID-19 virus.

Great experience. Easy to order and delivered in 2 days. EXCELLENT quality materials and the elastic head bands don’t stretch or break. I am a customer for life thank you Shawmut!

Frank Defabio

The way the seal around the cheeks and nose is designed, it helps prevent eyeglass fogging better than any other design I have tried.

The Protex™ All-Day-Comfort™ System

Using 3D scanning, in-house testing and rapid prototyping, Shawmut innovated the N95 respirator with its patent-pending Protex™ ADC™ all-day-comfort system to include:

  • High-sealing, slow-recovery viscoelastic nose foam for a secure and comfortable seal that provides a better fit without excessive pressure on the face and skin
  • A uniquely soft but strong inner layer to reduce abrasiveness on the skin
  • An incredibly lightweight but highly efficient and effective inner filtration layer

Combined together, the components of the Protex™ All-Day-Comfort™ System deliver new levels of comfort, performance, fit, seal, and protection providing:

  • Less air resistance – our proprietary filtering technology exceeds N95 standards while allowing for lighter weight and higher breathability
  • Cooler and fresher air inside the respirator reduces humidity buildup
  • Less pressure on the face for all-day-comfort and wear, Protex™ N95 wearers feel the softness of the foam with less eyeglass fogging when shaped around the bridge of the nose properly
