Protex™ N95 Particulate Respirator, Model SR9520

NIOSH Approved | TC-84A-9295

Made by Shawmut Corporation, a world leader in advanced materials, the Protex™ SR9520 is a NIOSH approved N95 disposable respirator and meets NIOSH 42 CFR 84 N95 requirements for a minimum 95% filtration efficiency.

Designed, engineered, and manufactured in America, the cup-style Protex™ SR9520 respirator was created with patent pending ADC The Protex All-Day-Comfort System® technology so you can count on it to fit better, protect better, and breathe easier all day long.

An N95 respirator that doesn’t fit properly may not protect you. Protex™ N95s are designed to fit the widest range of face sizes and shapes and have received Fit Capability scores of up to 97% when tested against the ASTM F3407-20 Respirator Fit Capability (RFC) standard. Protex N95s come in two sizes: SR9520 (Medium/Large) and SR9520S (Small). Be sure to choose the size that’s right for you.

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

  • MORE SECURE FIT  Protex™ N95s are designed to fit a wider range of face shapes and sizes. And a better fit means better performance: Protex N95s remove more than 95% of all 0.3+ micron particles.
  • BEST-IN-CLASS BREATHABILITY Proprietary Shawmut MB™ filtering technology exceeds NIOSH N95 standards while delivering better breathability and cooler, fresher air inside the cup.
  • ALL-DAY COMFORT  Protex N95s feature softer, flanged edges that provide a more comfortable fit with less pressure on your face.
  • LESS EYEGLASS FOGGING  When formed around your nose and worn properly, the unique viscoelastic nose foam and aluminum nose clip reduce eyeglass fogging for better visibility.

    Shawmut MB™

    We make the important N95 filter layer in-house using our Shawmut MB™ meltblown technology to meet our exacting specs for the All-Day-Comfort System.


    The Protex™ SR9520 is intended for respiratory protection and removes more than 95% of airborne particles larger than 0.3 microns such as those generated from sanding, cutting, sawing, polishing, mowing, yardwork, raking, painting, repairing, grinding or general cleaning, fiberglass insulation, construction debris, or other heavy industries. It is also appropriate for general public masking and traveling recommendations, as well as liquid or non-oil-based particles from sprays that do not also emit oil aerosols or vapors.

      Just fine

      These are well packaged, but in the one box I've already used, one of the 5 has a strap break right away, and the rest were fine but very painful on the nose bridge if worn for 4+ hours. I bought these to be able to stay safe longer but not sure if this is it.

      They rock

      I've been using these for the past few years. They're comfortable and pass the fit test for me. I haven't gotten covid thanks to these masks.

      Love it

      They fit me perfectly and provide a good seal. I used them to protect against covid-19. I like The over-head straps because it doesn't stress my ears like over-the-ears straps do.

      The Protex N95 mask

      One of the best masks for keeping the environment much more clean and air born particles contained.
