With its innovative 2-way separating system as well as two air pipes parallel to the head the AMEO FRESH AIR SYSTEM ensures continuous inhalation of sufficient fresh air with always free D-TUBES. Therefore, the POWERBREATHER cannot be compared with a classic snorkel, since for the first time ever the swimmer has no pendulum breathing (i.e. undesirable CO2 accumulation, performance drop) with the POWERBREATHER. Thanks to the valve technology of the AMEO FRESH AIR SYSTEM, generally no water penetrates the breathing system of the POWERBREATHER, saliva and occasional moisture, e.g. during flip turns, are seemingly “automatically” and unnoticed removed from the system with every exhalation via the mouth.
