Echo Water Echo Flask is a rechargeable smart hydrogen water bottle designed to produce hydrogen-rich drinking water on demand using advanced electrolysis technology.

The Flask uses Solid Polymer Electrolysis (SPE) and Proton Exchange Membrane (PEM) technology, together with platinum-coated titanium electrodes, to introduce dissolved molecular hydrogen (H₂) into drinking water while maintaining a neutral water pH.

Two hydrogen-generation cycles allow you to choose the desired concentration. The 10-minute cycle produces up to 6 PPM (6,000 PPB) of dissolved hydrogen, while the 20-minute cycle produces up to 8 PPM (8,000 PPB).

A built-in touchscreen display provides convenient control directly from the bottle, while connectivity with the ECHO mobile app enables hydration tracking, settings and usage history.

With a capacity of approximately 350 ml (12 oz / 0.36 L), the Echo Flask is compact enough for everyday use at home, work, the gym or while travelling. Its rechargeable design uses USB-C charging, eliminating the need for disposable batteries.

For optimal hydrogen generation, Echo recommends using low-TDS purified water, such as reverse osmosis (RO), de-ionised (DI) or suitable filtered water.

The Echo Flask has undergone independent laboratory testing for hydrogen output, material safety and performance.

HOW TO USE

Fill the Echo Flask with plain drinking water. For best performance, use low-TDS water such as reverse osmosis (RO), de-ionised (DI) or suitable filtered water.

Use the touchscreen to select your preferred hydrogen cycle:

10-minute cycle: Produces up to 6 PPM / 6,000 PPB H₂.

20-minute cycle: Produces up to 8 PPM / 8,000 PPB H₂.

Allow the selected cycle to finish completely.

After every hydrogen cycle, release the pressure using the pressure-release valve before opening the Flask.

Drink the hydrogen-rich water soon after the cycle finishes.

The ECHO mobile app can be used to manage compatible settings and track hydration and usage.
