NIOSH-Approved N95 Filtration

This disposable respirator meets NIOSH N95 standards for at least 95 percent filtration efficiency against certain non-oil-based particles and aerosols. The 3M Advanced Electrostatic Media enhances particle capture while maintaining breathability. A Cool Flow Valve releases warm exhaled breath to reduce heat buildup inside the mask. Each pack contains 10 units for extended use.

Dusty Work vs Oil or Gas Hazards

The respirator suits sanding, drywall cutting, woodworking, sweeping, sawing, grinding and similar dust-producing tasks. It also helps filter pollen, mold spores, allergens and granular pesticides during gardening or yard work. Workers facing oil-based mists, solvent vapours, gases or oxygen-deficient atmospheres need a different class of protection not provided by this N95 rating.

Cool Flow Valve for Breathing Comfort

The integrated 3M Cool Flow Valve makes breathing up to 50 percent easier compared to the non-valved 8200 model. An adjustable M-noseclip and stretchable braided headbands create a secure, custom seal for various face shapes. Soft inner material and a lightweight design at 0.31 pounds per pack support comfort during long sessions.

Questions about this item

Will the 8511 respirator fit over my 8210 model safety glasses without breaking the seal?

The 8511 has an adjustable M-noseclip and stretchable braided headbands designed to create a custom seal; fit over specific eyewear frames depends on their shape and should be checked with a user seal check.

How do I verify the Cool Flow valve on the 8511 is releasing exhaled breath correctly after I put it on?

Perform a user seal check: exhale sharply; if air leaks around the noseclip or edges, readjust the straps and noseclip; the valve should open easily and close automatically when you inhale.

Does the 10-pack box of 8511 respirators include any replacement valves or filters, or must those be purchased separately?

The 8511 is a disposable respirator with a fixed Cool Flow valve and integrated filter media; no replacement parts are included or available — the entire unit is discarded after use.
