PFL (Positive Facial Lock) masks feature an exclusive Twist-Seal chin piece that 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. This mask is also available with an integrated Magic Arch, which prevents the mask from coming in contact with the user’s nose and mouth, making it easier to breathe while enhancing filtration efficiency.
