The 3M™ 8511 respirator is a NIOSH-approved N95 mask featuring Advanced Electret Media for ≥95% filtration efficiency at 0.3 µm, paired with a patented Cool Flow™ Exhalation Valve to reduce breathing resistance and keep the interior cooler and drier. Its lightweight cup design and adjustable fit make it ideal for extended wear in hot, humid, or dusty industrial environments.

Key Features

  • NIOSH N95 Certified (42 CFR 84)
  • Cool Flow™ Valve: Polyisoprene one-way valve for easy exhalation
  • Advanced Electret Media: Permanently charged polypropylene fibers
  • Cup-Style Shell: Rigid polyester/polypropylene for shape retention
  • Adjustable M-Noseclip: Aluminum for custom seal and fog reduction
