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.

Get Protex ADC for Advanced Protection and Comfort

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.

    Size: Medium/Large (M/L)

      Bummer, I bought 10 boxes of these for Christmas presents and everybody's giving me

      the same feed back; the glue that holds the elastic isn't very good. When I/they put them

      on, you have to be very careful. I'm an old guy with pony tail and I pop on in three

      of these masks, especially taking them off. To make matters harder, I'm still paying for

      the ten boxes through Affirm. They ARE more comfortable than some other N-95 masks I've bought but I think these would only be really useful for single use (not taking them on and off).

      Michael, thank you for your feedback, especially your comment about comfort. We worked very hard on that. The elastic is sized so it can stretch to fit a wide range of head and face sizes. We will replace any N95s that have any defects in the materials or construction that cause the straps to fail. Many of our users have found that when they pre-stretch the elastic slightly in the center of the bands before putting them on the first time, donning and doffing are much easier. Here is a link to our user instructions that include our recommended procedure for taking the respirators on and off.

      The elastic bands hurt.

      The masks are great except the elastic bands irritate our skin when we have to wear the masks for several hours. Even so, they are far better masks than many other types we have purchased in the past.

      Exceptional Protection Fits Securely on Larger Adult Head

      Since the outbreak of COVID-19, we always wear our Shawmut Protex N95 in public due to our higher vulnerability as older senior citizens. The M/L size provides exceptional protection fitting securely on our larger sized adult heads. We experienced less band separation and breakage with the M/L size that very few companies supply. Due to the triple threat of COVID, Respiratory Syncytial Virus (RSV), and seasonal flu we continue to double mask wearing the Protex N95 sealed closest to our face with a much less airtight blue face mask over the Protex N95. We trust the Shawmut brand manufactured locally in Massachusetts adhering to the strictest industry standards. All of the N95 were well made and packaged carefully indicating that Shawmut takes immense pride in manufacturing their superior products. Shawmut's quality control of their N95 masks is truly exceptional.
