Features of One Way Valve Mouth Piece

• The One-Way Valve Mouthpiece is a disposable paper mouthpiece featuring a one-way valve for expiratory-only testing. The plastic valve has been designed to provide low air resistance.

• The valve will allow exhalation through the Spirometer, but will not allow inhalation. By not being able to breathe in, the risk of cross-contamination is greatly reduced.

• This One-Way valve mouthpiece is made of high-quality cardboard and is fitted with a plastic valve insert. The valve is then ultrasonically welded to the plastic insert and is structurally enhanced to prevent leaking.
