Product Details
Inside every Echo device is special technology that turns normal water into hydrogen-rich water.
At the center is the Echo Hydrogen Generator. It uses two titanium plates coated with platinum and a thin proton exchange membrane between them. These laboratory-grade materials are chosen because they are strong, clean, and safe.
The proton exchange membrane was first made for NASA. Today, it’s used in hydrogen cars and other advanced machines. It lets pure hydrogen gas mix into your water while the oxygen is released into the air.
Our carefully shaped plates make sure the electric current spreads evenly, without heat or damage. That means the Echo Hydrogen Generator makes hydrogen faster and more efficiently.
Every part is built from laboratory-grade materials and made to last a long time—so you can always count on clean, high-quality hydrogen water.
Lab Results
The ECHO Hydrogen Flask has been lab‑tested and certified by H2 Analytics (Report H2AR‑250116‑1, dated January 16, 2025). Using gas chromatography testing on distilled water, the Flask consistently delivered 6.07 mg/L of dissolved hydrogen after a 10‑minute cycle and up to 8.25 mg/L after 20 minutes—well within the highest range of tested levels.

The US Food and Drug Administration has recognized hydrogen gas as a food additive is generally recognized as safe. The research confirms that hydrogen water is safe to be consumed. The ECHO Flask currently has a valid certification status by H2 Analytics in conformance with IHSA and US EPA standards. Registration# 24-0701-1-PB

The smallest molecule in the universe, Hydrogen has been studied for its ability to support healthy energy metabolism and redox balance—two key drivers of stamina, metabolic efficiency, and humans who push harder and go further.
Fuel your cells by supporting the systems behind endurance and recovery. By helping your body manage oxidative stress, it promotes better performance under pressure—whether you’re crushing a workout, a deadline, or both.
Resilience isn’t optional—it’s your edge. Hydrogen water can play a role in cellular signaling, stress recovery, and aging resilience. When your cells bounce back faster, so do you. Stay sharp, stay strong, and live fully charge
Real recovery starts at the source. Hydrogen-rich water is being explored for its potential to support the body’s natural repair processes. Whether you're training, fasting, or just demanding more from life, hydrogen is your quiet recovery ally.
Your gut isn’t just about digestion—it’s a command center for immunity, energy, and mood. Research suggests hydrogen may support gut balance and reduce oxidative load, helping you feel more aligned from the inside out.
Hydrogen has been studied for its ability to help the body manage inflammation and oxidative stress in the brain—factors that influence focus, alertness, and mental endurance. Stay in the zone, longer.

FAQs
What is hydrogen water?
Hydrogen water is regular water that has been infused with molecular hydrogen (H2) gas. This creates water with antioxidant properties that may provide various health benefits.
What are the benefits of hydrogen water?
Hydrogen water may provide antioxidant benefits, reduce inflammation, improve energy levels, support cognitive function, and promote overall wellness. Research suggests it may help with various health conditions.
When should I start seeing the benefits of hydrogen water?
Everyone is different. Some people notice benefits within days or weeks, while for others it’s more subtle. Hydrogen water works a lot like a daily vitamin—its effects build over time.
Many of its benefits, like reducing oxidative stress and supporting a healthy inflammatory response, happen at the cellular level, so you may not feel immediate changes—especially if you already feel healthy. However, these processes are important for long-term health and aging.
In short, hydrogen water may be less about noticeable day-to-day effects and more about supporting your health over time. Read more about it here
What research has been done on hydrogen water?
Extensive research has been conducted on molecular hydrogen and hydrogen water, with over 1,000 scientific studies published. Research covers areas including antioxidant effects, anti-inflammatory properties, and potential therapeutic benefits.
Doesn't water already contain hydrogen?
While water (H2O) contains hydrogen atoms, it doesn't contain molecular hydrogen (H2) gas. Hydrogen water is specifically infused with dissolved molecular hydrogen gas, which provides the antioxidant benefits.
How often should I drink hydrogen water?
For optimal benefits, it's recommended to drink hydrogen water daily. Many people consume 1-3 glasses per day, though individual needs may vary. Consistency is key to experiencing the full benefits.
Can I add supplements to the Flask?
Do not add any supplements directly into your Flask - Use plain water only in the Flask. Adding flavorings, supplements, or powders inside the device can interfere with the electrolysis process and may shorten the life of the unit. If you prefer flavored water or supplements, enjoy them after generating hydrogen water by mixing them in a separate container. Please note that adding ingredients or stirring may reduce the amount of dissolved hydrogen, as hydrogen naturally escapes from water over time. For the highest hydrogen levels, enjoy your hydrogen water soon after it’s made.
Can I put the Flask in the dishwasher?
No. The Echo Flask must be handwashed only. Avoid dishwashers and submerging the device. Doing so will void your warranty.
Where is the Flask Manual?

Why did my Flask arrive with Water?
The Flask™ contains a small amount of distilled water to keep the membrane primed, because a hydrated membrane matters - efficient hydrogen production, consistent bubble formation, optimal performance from the start, and membrane protection. Your Flask™ is clean and ready to use. Simply discard the water, rinse, and fill it with purified or distilled water for best performance.
If your Flask arrived without water, or if it hasn’t been used for a while and has dried out, no worries —that is completely okay! It simply means the electrode membrane may need a little rehydration before use.
How do I remove the lid?
Hold and Release the Pressure for ~3 seconds. Twist off the cap by gripping the sides of the lid, pressing downward on the sides (not on the pressure release, this is after you've already released the pressure) and twist counterclockwise, applying gentle force, similar to opening a pill bottle. Read more about the lid here
What type of water should I use?
We highly recommend using filtered, distilled, or reverse osmosis (RO) water for optimal performance and a clearer understanding of what you’re consuming. While tap water can be used, it contains unknown chemicals and minerals that may shorten the flask’s life. Increased buildup could also require more frequent cleaning. Read more about it here
Why is there water underneath the bottom of my Flask?
Small drips from the oxygen port are normal. This is not considered a leak—it’s an occasional and expected result of oxygen being expelled through the port (even beyond the first use). This is one of the features on our PEM membrane that sets us apart from others - It prevents oxygen or contaminants from flowing back into the water.
Small drips can range from a quarter-sized spot to the size of the flask base. Read more here to Understand your Flask™ Generator
Should I hear a Pressure Release sound after running a cycle?
Your Echo Flask™ is designed to automatically, and safely manage internal pressure during and after each hydrogen cycle. Because of this, you may hear different sounds — or none at all. Whether you hear it or not, sound variations do not affect hydrogen concentration (PPM).
When should I charge my Flask?
Your Echo Flask™ is designed to run 5–7 cycles of 10 minutes or 3–4 cycles of 20 minutes per full charge.
Your Flask will indicate when the battery is low, but letting it fully deplete before charging helps maintain proper battery calibration — allow the Flask™ to run until it can no longer complete a full cycle.
Why? Your Flask uses a lithium-ion battery paired with battery management software. When the battery is new, the system’s percentage readings may not yet be perfectly calibrated. This is known as a battery calibration period. Read more about it here
How often should I Clean my Flask?
Your Echo Flask™ is designed to be very simple to take care of - weekly, we recommend a quick rinse and occasional wash with mild soap—similar to any reusable water bottle. The built-in “Clean” cycle also does most of the work for you, so there’s nothing complicated.
As for deeper cleaning, we only recommend about once a month and simply involves soaking it in a water + vinegar mix—no special tools or products needed.
