Features of the Alpha ProTech PFL Headband Face Masks with Magic Arch Supports:
Innovation is built into these high performance masks. The patented Positive Facial Lock® with the exclusive Twist Seal® lets the user create a secure custom fit to help eliminate the possibility of inhaling small particles...no gaps around the border of the mask.
The patented Magic Arch® internal support holds the mask away from your nose and mouth to let you breathe easier, enhance filtration performance and maintain maximum comfort...all without impeding "downward vision."
The hypoallergenic materials used in the PFL masks create a durable exterior and a soft, comfortable interior.
