This 3M 8511 N95 Respirator is a professional-grade particulate respirator featuring a Cool Flow™ Valve, designed for comfort and protection during tasks that generate dust, mists, or particles.

• N95 Protection: This mask is NIOSH-approved to filter at least 95% of non-oil-based airborne particles, making it ideal for tasks like sanding, grinding, sawing, or cleaning insulation and masonry.

• Cool Flow™ Valve: The integrated one-way valve is a major advantage for long-duration use. It allows exhaled air to exit the mask easily, reducing heat and moisture buildup inside the respirator, which prevents the mask from becoming damp and improves overall wearer comfort.

• Application: It is a staple for job-site safety, protecting against common construction dusts like concrete, wood, drywall, and fiberglass.
