The high concentration oxygen mask is perfect for those who want a precise, non-rebreathing mask.
The elongated high concentration non-rebreathing oxygen mask is designed to allow for proper oxygen concentration using the precision check valve. The clear and soft anatomical form gives you long-term comfort, even for those with traditionally hard to fit faces. The adjustable elastic band fits below the ears comfortably while holding the mask snugly in place. It comes with a seven foot three channel safety tube.
