How does your Echo Go (and Echo Go+) bottles work?

Echo hydrogen water devices use electrolysis to separate water molecules into hydrogen and oxygen gas. The oxygen gas is sent out to atmosphere and the hydrogen gas is dissolved into the water, creating hydrogen-rich water.

The Echo Go+ device has two platinum coated electrodes separated by a proton exchange membrane. Water is added to the electrolytic chamber where the water molecules are separated into hydrogen and oxygen gas.

The PEM separating the electrodes prevents the hydrogen from mixing with the oxygen, allowing only hydrogen gas to be dissolved into the water. The resulting hydrogen-rich water can then be consumed.
