Key Benefits

• Provides up to 8 ppm hydrogen to support cellular health and performance.

• Monitors intake and hydrogen levels.

• Secure grip and travel-friendly design.

• 12-ounce capacity.

• Bluetooth connectivity that syncs with your phone for insights.

The Echo Flask takes hydration to the next level with cutting-edge hydrogen infusion technology. Using an advanced proton exchange membrane, it produces up to 8 ppm of molecular hydrogen—far surpassing standard hydrogen bottles. Hydrogen-rich water is scientifically known to support cellular health, enhance recovery, and improve energy levels.

Designed for performance and convenience, the Echo Flask features a sleek, durable build with a 12-ounce capacity—perfect for longer hydration without frequent refills. The non-slip textured surface ensures a secure grip, while its compact design fits seamlessly into cup holders for effortless travel. A quick-latch lid with a pressure release valve allows for smooth, spill-free hydration. The smart digital display tracks hydrogen potency and hydration cycles, while Bluetooth connectivity syncs with your phone for personalised insights.

Stay hydrated, recover faster, and optimise wellness with every sip.

Note: The Echo flask comes with a charging cable only.

Echo offers advanced water filtration systems that infuse water with hydrogen molecules to enhance hydration and wellness. Unlike many hydrogen water machines, Echo Hydrogen Water Machines are designed to deliver consistent hydrogen infusion for long-term use. The technology infuses hydrogen without altering the water’s pH, maintaining the water’s natural balance. Echo makes it simple and effective to enjoy the benefits of hydrogen-enriched water, elevating your hydration experience.

1. Fill the bottle with warm, filtered water and run a cycle.

2. Secure the cap by twisting until you hear a "click" (ensure the logo aligns at a 90-degree interval).

3. Release pressure by pressing the side marked with a circle before removing the lid.

4. Listen for a faint hiss or pop and look for bubbles rising, confirming pressurization.

5. Discard the water, rinse the flask, and it's ready for your first hydrogen cycle.

Reverse Osmosis, Distilled, Spring, or Filtered water is recommended. Do not use carbonated or non-water beverages.

Do not directly add supplements, minerals, or flavoring to the flask; use a separate container.

For optimal benefits, consume hydrogenated water within 2 hours. However, the lid's design minimizes hydrogen escape, allowing the water to maintain similar PPM levels even if left overnight.

Operation and Charging


Do not disassemble, modify, or repair the Echo Flask™; this will void your warranty.


Avoid excessive force or impacts; contact customer support if the flask is dropped or damaged.


Do not operate the generator without water in the flask.


While charging, limit cycles to (1–2) 10-minute cycles. Each charge supports up to 5-7 10-minute cycles.


If the electrodes have been dry or unused for one week or longer, rehydrate the flask (see the "Initial Set Up: Rehydration" section in this manual).


Ensure only manufacturer-certified replacement parts are used.


Avoid touching the charging cord or USB-C input with wet hands.

Storage, Cleaning, and Maintenance


Keep the electrode plate wet with one tablespoon of water; do not store it completely dry. If your bottle dries out, it will need to be rehydrated.


Avoid storing with excessive water to prevent mold or mildew.


Leave the cap off briefly after use to allow moisture to dissipate.


When cleaning, use citric acid or white vinegar only. Avoid chemicals or dish detergent.


Do not clean the interior of the flask with chemicals; this can damage the electrodes. Only vinegar or citric acid should be used.

Safety and Handling


Always keep the Echo Flask™ out of reach of children and pets to ensure their safety and prevent accidental damage to the device.


Avoid heat, flames, and hot or humid environments (e.g., saunas, hot vehicles).


Do not place the Echo Flask™ on non-waterproof surfaces to avoid potential damage in the event of a leak.


Avoid direct sunlight or heat that could dry out the electrode plate.


Do not soak or submerge the flask or cap in water.


Do not microwave, refrigerate, or freeze the Echo Flask™.


Handwash only; do not place any component in the dishwasher.
