PFL (Positive Facial Lock) masks feature our exclusive Twist-Seal chin piece which allows a custom fit to any size face, reducing potential for small particles to be inhaled around the borders of the face mask. This unique design virtually eliminates gaps at the border of the mask.

The Positive Facial Lock® (PFL®) N-95 Particulate Respirator meets the World Health Organization (WHO) and the Centers for Disease Control (CDC) recommended protection levels (where applicable) for many airborne contaminants. NIOSH Certified, our N-95 delivers the appropriate amount of filtration efficiency and, when combined with a trio of patented and unique design features, also delivers the user a comfortable, custom-fitting facemask. The integrated Magic Arch® technology creates a breathing chamber within the facemask by holding it away from the user's nose and mouth. Our PFL technology, incorporating an integrated Twist Seal® chinpiece, helps the wearer create a perfect fit every time.
