3M Particulate Respirator helps reduce exposure to dust from sanding on particle board, drywall or non-lead based paints, fiberglass insulation dust, and airborne particles that do not contain oil. It is recommended for use when sanding and working with fiberglass insulation and drywall sanding. A Cool flow exhalation valve allows easy exhalation and heat reduction, which provides cool, dry comfort. The M-Nose Clip conforms easily around the nose bridge with fewer pressure points and greater comfort. An all-filter design provides economical protection, with no spare parts to clean and maintain and the cake-resistant filter media prolongs respirator life while maintaining ease of breathing.
