3M 8511HA1-C-PS N95 Sanding Valve Respirator Niosh

Product Description

The 3M 8511HA1-C-PS is an N95-rated particulate respirator with a built-in Cool Flow exhalation valve, designed for use during sanding, grinding, sawing, and fiberglass insulation work. NIOSH approved to filter at least 95 percent of airborne non-oil-based particulate matter, it provides reliable respiratory protection in dusty work environments. The patented Cool Flow valve reduces heat and moisture buildup inside the mask by allowing exhaled air to escape efficiently, keeping the wearer cooler and drier during sustained work. Each unit is individually packaged. The respirator is suited for trade professionals and contractors who encounter fine particulate hazards on the job.

This respirator is intended for tasks that generate non-oil-based particulates, including drywall sanding, wood grinding, fiberglass insulation handling, and general construction sawing. It is appropriate for residential and light commercial jobsites where particulate exposure is a primary concern. The individual packaging keeps each unit clean and ready for use until needed, making it practical for job site distribution or kit stocking.
