Product Overview
The 3M™ 8511 Particulate Mask Respirator (N95) is a NIOSH-approved disposable respiratory protective device designed to filter out at least 95 % of airborne non-oil based particles. It combines 3M’s proprietary Cool Flow™ exhalation valve, advanced filter media, and ergonomic design to enhance comfort and breathability — especially during long wear in dusty, hot, or physically demanding environments.

Features
NIOSH-Approved N95 Filtration
-
Certified to filter ≥ 95 % of non-oil based particulates — including dusts, pollen, and fine particles from woodwork or construction.
3M™ Cool Flow™ Exhalation Valve
-
A one-way valve that helps reduce heat and moisture build-up inside the mask by expelling exhaled air more efficiently, improving comfort during long shifts or in hot/humid conditions.
Advanced Electret Filter Media
-
Proprietary filter media from 3M is optimized for easier breathing without sacrificing filtration performance.
Adjustable M-Noseclip
-
Helps form a better facial seal, minimizes gaps, and reduces eyewear fogging for users wearing glasses or goggles.
Braided Headbands & Secure Fit
-
Dual-strap design with braided elastic offers a more secure seal and ergonomic tension for a stable fit.
Cup-Shaped, Spacious Design
-
Offers a durable shell that keeps the mask’s shape while providing more room inside the respirator, helping with comfort and easier breathing.
Benefits
Enhanced Comfort
-
The Cool Flow™ valve significantly reduces heat and moisture accumulation, making the mask more comfortable to wear for extended periods — particularly useful in hot, humid, or strenuous work environments.
Ease of Breathing
-
Advanced electret media reduces breathing resistance compared with some older respirator designs, helping reduce fatigue during extended use.
Versatile Usage
Ideal for industrial and occupational tasks like sanding, grinding, sweeping, welding preparation, woodworking,
and other dusty operations where particulate exposure is a concern.
Improved Fit & Reduced Fogging
-
The M-noseclip and secure headbands help maintain a good seal and can reduce fogging for workers wearing protective eyewear at the same time.
Hot/Humid Environment Friendly
-
Especially recommended if users frequently experience heat build-up inside masks — the exhalation valve helps keep the interior cooler and more comfortable compared with non-valved respirators.
Limitations & Safety Notes
-
❗ Not suitable for oil-based aerosols or gases/vapors — only particulate hazards.
-
❗ Proper fit and seal are critical — facial hair or incorrect positioning can compromise protection.
-
❗ Valve means exhaled air is not filtered — which may be unsuitable in sterile or infection-control settings (e.g., some medical environments).
Typical Applications
-
Construction & renovation (dust from cutting, sanding)
-
Manufacturing & fabrication (particle exposure)
-
Woodworking & carpentry
-
General industrial housekeeping (sweeping, cleaning
