This disposable N95 particulate welding respirator helps provide respiratory protection for applications such as welding or soldering where metal fumes may be present. Features the 3M Cool Flow Valve which is designed to release hot, humid exhaled breath quickly, helping to prevent an unpleasant buildup of heat inside the face-piece, a significant cause of discomfort to respirator wearers. Fully adjustable straps provide added comfort. Incorporates 3M's Advanced Electrostatic Media, a proprietary filter media with electrostatically charged microfibers designed for easy breathing. N Series respirators are used in particulate environments free of oil aerosols. Suggested applications: welding, torch cutting, brazing, soldering, and metal pouring.
