STEDAIR® PREVENT

Stedair® PREVENT – Particulate Hood Technology
Certified to NFPA 1970

Stedfast is proud to lead the industry in particulate-blocking hood technology. Stedair® PREVENT is the only highly breathable, air-permeable, and flame-resistant material that offers superior particle-blocking performance and durability.

This barrier technology is the industry's leading particle-blocking hood material, providing the best solution for firefighters:

  • Protection against dangerous, cancer-causing particles
  • Thermal protection from burns
  • High Total Heat Loss, for superior comfort and protection from heat stress

Hoods made with this technology are the most durable in the field, passing over 200 ISP launderings while still maintaining superior particulate-blocking performance — the ultimate combination of protection and comfort.

Now available in two technologies

The original formulation remains our proven, industry-trusted choice. For a non-PFAS option, Stedair® CLEAR PREVENT combines this particle-blocking performance with the state-of-the-art chemistry of Stedair® CLEAR. 

Together, they form a next-generation particulate barrier that delivers protection without compromising breathability, durability, or comfort.
Both technologies are certified to NFPA 1970.
