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.

The addition of extra hydrogen gas into water does not add or change the taste.

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 

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.
