Hydrogen (H2) infused water has been clinically proven to support
inflammation, digestion, focus and sleep!
Reduce oxidative stress and prevent lactic acid buildup during workouts.
Move with less stiffness and more confidence in your body.
Stay mentally sharp and in control throughout your day.
Get the kind of rest that leaves you clear, calm, and ready.
H2 activates the body's natural antioxidant defenses, such as increasing the activity of antioxidant enzymes.
H2 easily moves through cell membranes, allowing it to reach and neutralize highly dangerous Reactive Oxidative Species (ROS) in various tissues and organs.
H2 reduces inflammation by stopping the body’s inflammatory response.
Using our proprietary Solid Polymer Electrolysis technology, the Echo Flask
turns ordinary water into pure therapeutic hydrogen water, on demand.
Unlock the power of hydrogen-infused water – your secret weapon for enhanced energy, faster recovery, and a boosted metabolism. The sleek, portable Echo Flask Bottle delivers antioxidant-rich hydration that fights fatigue, supports weight management, and fuels your body.
Improve power performance, heart rate recovery, and reduce oxidative stress! Studies involving athletes such as dragon boat racers and cyclists, found that Hydrogen Water can boost performance and recovery times by mitigating exercise-induced fatigue and inflammation.
70% to 80% of the immune system is housed in your gut. Stress, poor diet, and pesticides weaken your gut to nearly 20% functionality. The electrical potential in Echo H2 Water™ repairs and restores the gut and improves food intolerances.
As a selective antioxidant, hydrogen water has been proven to improve mental clarity, prevent cognitive illness, reduce oxidative stress and inflammation, boost mental focus and clarity, and help with mental illnesses.
By neutralizing harmful free radicals and oxidative stress, hydrogen water has been proven to help regulate heart disease, diabetes, reduce wrinkles and skin issues, and speed up wound healing.
Reducing oxidative stress does more than increase recovery; it helps slow aging while maintaining skin elasticity. Additionally, its antioxidant properties can support hair growth and strength, enhancing blood flow and promoting overall wellbeing.
Stay hydrated longer,
feel better faster.
The Echo Flask gives you 50% more capacity (12oz, 350ml),
so you stay hydrated longer without constant refills.
More of what your body needs, exactly when it needs it—no hassle.

Very happy with my Echo Water Flask. It is well made and seems to operate perfectly. My wife and I are feeling better, sleeping better and have more energy. More to come.
After using this flask for almost 4 weeks, I can report: less bloat, more energy, better mental clarity, and improved workouts. I love everything about this and what it's done for my health in such a short time! I can't wait to keep using it!
I am not new to Echo, as I have had an Echo Go+ for the past year. But I can tell you that the Flask is definitely next level! Great hydration in the palm of your hand is a guarantee. The touch pad is cool and the app to keep track of your intake is really cool as well.
Great product! My husband and I are both enjoying the results from drinking the hydrogen water. We both noticed a better energy level and clearer minds almost immediately after starting it. It helps me with my endurance during workouts and when walking and running.
This bottle is just amazing; how it looks and the benefits are good as they say. l go with it every place. l started using the hydrogen water and my body feels different, plus l get good sleep.
I drink around 5 full hydro flasks a day and have really started to feel a difference in less than a month. Super easy to use and makes for a great conversation piece when on.
Great design, easy to use, noticeably quick results.
This is the best water bottle I've ever purchased!!
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.

Echo Hydrogen Water offers the wellness benefits associated with antioxidants, including support for natural energy, mental clarity, and overall wellness. There are over 1500 studies exploring the potential wellness benefits of hydrogen-enriched water.
Not at all. Many hydrogen bottles under-deliver — with low hydrogen output, poor durability, and risky chemical byproducts. The Echo Flask is lab-tested to deliver pure hydrogen gas into water safely and consistently. No contaminants. No guessing.
We use advanced SPE/PEM technology and platinum-coated titanium plates to deliver ultra-pure molecular hydrogen—up to an industry-leading 8 PPM with zero harmful byproducts. It pairs seamlessly with the Echo app, allowing you to track hydrogen cycles, monitor usage, and customize your hydration routine. Cheaper bottles often use inferior metals and can produce chlorine or ozone. This isn’t just premium—it’s precision-engineered wellness.
Yes. All materials are third-party certified. Our hydrogen generation method is proven safe, and every Flask comes with a 60-day money-back guarantee and 5-year warranty—best in the industry.
No. The Echo Flask is made with quality materials like titanium and platinum, as well as an oxygen release port to ensure no pH shift or contamination of metals.
The Echo Flask is made from premium PPSU plastic—free of BPA, BPS, BPF, BPB, and BPC. This is the same high-performance material used in baby bottles and medical devices. It’s built to handle the 55–77 PSI pressure generated during hydrogen cycles—pressure that would easily shatter glass. It’s also designed for long-term use. The durable build, combined with our 5-year warranty, means the Flask is made to last—not to be thrown away after a few months.
There is no standard recommendation for how much hydrogen water to drink. Some studies have explored using doses of 1–3 liters per day. With the Echo Flask, many users enjoy drinking at least 3 bottles a day, spread throughout the day. For personalized advice, it’s best to consult with a healthcare professional based on individual health needs.
For optimal benefits, we recommend drinking within the first 2 hours. However, hydrogen retention depends on how the water is stored:
Open glass: Lasts up to 2 hours in an open, unsealed container
Water bottle: Keeps hydrogen for 3–5 hours in a bottle you open occasionally (best concentration in first 2 hours)
Sealed container (Echo Flask): In a fully airtight container, hydrogen decreases by only ~0.1 PPM per day and can remain for up to 2 weeks depending on starting levels
The addition of extra hydrogen gas into water does not add or change the taste.
For best results, we recommend filtered water. The Echo Flask adds dissolved hydrogen gas but doesn’t remove contaminants. Clean water in = clean hydrogen-rich water out. The Echo Flask will still infuse hydrogen gas with tap water, but we always recommend filtered water for your health as well as the health of your Flask.
Not everyone feels an immediate boost, but the benefits are happening under the surface. Just like vitamins, hydrogen works at the cellular level, reducing oxidative stress and supporting better health over time.
Yes. It’s been studied across all age groups with no known side effects. It’s non-toxic, naturally produced in your gut, and supports cellular health in the young, old, and everyone in between.
No. Hydrogen water is not the same as alkaline or ionized water. It simply infuses pure H₂ gas into water. That’s the therapeutic molecule linked to over 1,500 peer-reviewed articles on energy, inflammation, recovery, etc.
No, none of the Echo Hydrogen Water products restructure water, but they all effectively dissolve hydrogen gas into infused nanobubbles within the pressurized chamber. This is the secret ingredient that acts as a selective antioxidant and cellular messenger, supporting energy, focus, and recovery.
Research on hydrogen water is ongoing, and some studies suggest it may support wellness efforts, including energy levels and overall vitality, which could complement a balanced approach to weight management.
Hydrogen water has antioxidant properties that may have a detox-like effect, supporting the body’s natural processes in managing exposure to environmental elements like pollution. Particulate matter can impact wellness, so staying hydrated with hydrogen-enriched water may help support your body’s natural defenses.
In order to prevent the proton exchange membrane in the base of the flask from drying out, your flask may arrive with some water or water vapor inside.
