01: an essential bodily element
The first element on the periodic table, hydrogen is a critical element to bodily function, making up 9.5% of body mass. It’s microscopic structure allows it to rapidly diffuse and easily penetrates cells, clearing out cellular 'noise' and restoring balance.
02: Rich, Bioavailable, & Naturally Sourced
The Echo Flask uses cutting-edge PEM technology and internal pressure regulation to split water molecules using only H₂O—no chemicals, no cartridges. Oxygen is safely vented through a bottom release port, while pure molecular hydrogen is infused back into the water and stabilized in ultra-fine nanobubbles. Once consumed, these hydrogen-rich bubbles rapidly diffuse into tissue, supporting hydration, cellular signaling, and redox balance from the inside out.
03: Peer-Reviewed. Scientifically Backed
While scientists are still uncovering hydrogen’s full potential, early research suggests it may play a key role in supporting cellular balance and resilience. Over 1,500 studies have investigated molecular hydrogen across a wide range of health and performance contexts—including inflammation, aging, metabolism, and recovery. As the science evolves, one thing is clear: hydrogen is shaping the future of proactive, performance-driven wellness.
04: Performance from the Inside Out
Trusted by experts but designed for daily living, ECHO makes hydrogen health accessible and effective. Whether you’re at the gym, in the office or playing with the kids, hydrogen water has everything you need to help you live better, longer.
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.
Turning H20 into H20+H2
The Perfect Hydrogen Generator
Our propriety proton exchange membrane (PEM) is the heart of a precision electrolysis system that splits water into hydrogen and oxygen.
Acting like an atomic filter, it allows only pure protons to pass through without the accumulation of ions, unwanted gasses, or dangerous byproducts. These protons then recombine with electrons to form clean, molecular Hydrogen (H2), which is infused directly into your water for maximum freshness and therapeutic benefit.

What is hydrogen water good for?
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.
Is all hydrogen water the same?
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.
What makes the Echo Flask better than other hydrogen water bottles?
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.
Is the Echo Flask certified for safety?
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.
Does the Echo Flask change water pH or add metals?
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.
Why isn’t the Echo Flask made of glass?
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.
How often should I drink hydrogen water?
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.
What does hydrogen water taste like?
The addition of extra hydrogen gas into water does not add or change the taste.
How long does hydrogen stay in the water?
How long does hydrogen stay in the water?
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
Can I use any water in the Echo Flask?
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.
What if I don’t feel anything?
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.
Is hydrogen water safe for kids or elderly people?
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.
Is hydrogen water the same as alkaline or ionized water?
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.
Does the Echo Flask “restructure” water?
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.
Can hydrogen water support weight management?
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.
Does hydrogen water ‘detox’?
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.
Why did my flask arrive with water in it?
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.
