3M™ Particulate Respirator 8233 – N100 Valved Mask

The 3M™ Particulate Respirator represents NIOSH’s highest rated filtration efficiency for a maintenance-free disposable mask. Designed for professionals working in high-risk environments, it offers a minimum filtration efficiency of 99.97% against non-oil-based airborne particles, making it far superior to standard N95 models.

Key Features & Benefits

• Maximum N100 Protection: Filters at least 99.97% of airborne particles as small as 0.3 microns, including heavy metal dust and toxic fumes.

• 3M™ Cool Flow™ Valve: Proprietary exhalation valve effectively releases hot, humid breath to keep the wearer 7.5°F cooler and significantly reduce eyewear fogging.

• Foam Face Seal: Features a soft, conformable outer foam face seal that ensures a more secure and comfortable fit during long shifts.

• Fully Adjustable Straps: Equipped with fabric-coated elastic straps and adjustable buckles for a customized, snug seal without excessive pressure.

• Advanced Electret Media: Electrostatically charged microfibers enhance particle capture while keeping breathing resistance low.

This respirator is an ideal choice for tasks involving OSHA substance-specific contaminants (excluding asbestos) such as:

• Lead Abatement & Pharmaceutical Manufacturing: Critical for handling high-toxicity dusts.

• Welding & Metal Pouring: Protects against metal fumes and hazardous vapors.

• Heavy Construction: Effective for concrete grinding, sanding, and demolition.

• Refining & Mining: Suitable for foundry operations and mineral processing
