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.
