3M 8511 - Particulate Respirator N95, Box of 10

The 3M 8511 N95 Particulate Respirator with Cool Flow™ Valve offers reliable 95% filtration efficiency for non-oil-based particles, using advanced electret media for lower breathing resistance. The Cool Flow™ valve significantly reduces heat build-up inside the mask, providing a cooler microclimate during extended wear. Designed with a comfortable cup shape, adjustable M-nose clip, and braided dual-braided elastic headbands, it delivers secure fit and comfort in hot, humid, or physically demanding work environments such as grinding, sanding, and sweeping.

Key Features:

• NIOSH-approved N95 rating: filters at least 95% of certain non-oil-based particulates
• Cool Flow™ exhalation valve that reduces internal heat and humidity
• Adjustable M-nose clip to minimize lens fogging and improve seal
• Durable cup design with cushioned interior enhances comfort and fit
• Secure dual-point braided elastic headbands for stable wear

• Packaging: 10 respirators per box; 8 boxes per case (80 total units)
• Filter class: N95 (non-oil particulate protection)
• Valve: Cool Flow™ exhalation valve included
• Strap type: Dual braided elastic straps with wired attachment
• Shape: Rigid cup, disposable design
• Certifications: NIOSH-approved (42 CFR 84)
• Typical applications: grinding, sanding, sweeping, bagging, and general respirable dust environments

• Conduct a user seal check by covering the exhalation valve area and inhaling; the mask should collapse slightly and hold without leaks.
• Avoid touching or adjusting the mask during use to prevent contamination and compromise of the seal.
• Replace the respirator immediately if you detect smells, experience breathing resistance, or notice dampness inside the mask.
• Dispose of the respirator according to safety regulations and avoid reusing.
• Store unused units in a sealed, clean container to preserve filter integrity and cleanliness between uses.

Q: Can the Cool Flow™ valve be removed or disabled?
A: No—it’s integral to the design and cannot be removed without compromising performance.

Q: Will this respirator fog my safety glasses?
A: The adjustable M-nose clip helps direct exhaled air downward, reducing fogging.

Q: Is this respirator suitable for oil-based aerosols?
A: No—it’s rated for non-oil-based particulates only (N95).

Q: Can I reuse this mask if I sterilize it?
A: No—it is a single-use design and should not be reused after exposure or attempted cleaning.

Q: Why choose this model over the 8210?
A: The 8511 includes the Cool Flow™ valve, which significantly reduces internal heat, making it more comfortable in warm or humid conditions.
