3M Paint Sanding Respirator filters the non-harmful dust from sanding, grinding, sawing, and insulating particles. The advanced filter makes for easier breathing, while interior foam at the nose and M-shaped clip allow for fewer pressure points and greater comfort. Easy to use and disposable, the 3M respirator is a great choice for respiratory protection for both professional and personal projects. Provides at least 95% filtration efficiency against solid and liquid aerosols that do not contain oil. Free from natural latex rubber. One size fits most. NIOSH approved: N95.
