NIOSH-approved mask designed to fit better, make breathing easier and protect workers from a variety of contaminants. It features a contoured design and a pre-shaped molded nose bridge designed to fit most facial contours. PeakFit uses a closed-cell foam on the inside of the mask instead of a metal nosepiece. It is available in three versions: PeakFit, PeakFit OV and the PeakFit AG. PeakFit and PeakFit OV are available with an optional exhalation vent.
