The AMEO PowerBreather PB01 is an innovative sporting equipment that allows swimmers to breathe fresh air under water. Unlike in conventional snorkels, a new valve technique, which was developed to incorporate ergonomics and design, reduces the risk of exhalation air (remaining in the tubes and containing CO2) being re-inhaled into the lungs i.e. reciprocated breathing. Thanks to the sequential FreshAir system, the product ensures an optimal oxygen supply over an unlimited period of time.
