High-concentration hydrogen water, built for your daily routine.
Meet the Echo Flask — hydrogen water, generated fresh, wherever you are.
Delivering up to 8,000 ppb (8 ppm) molecular hydrogen with intelligent tracking and connectivity, the Eco Flask transforms how you hydrate and fuel your day. Support cellular vitality and unlock peak performance with every sip.
The Echo Flask is a 12-ounce portable hydrogen water bottle designed for daily use at home or on the go. It uses dual-chamber SPE and PEM electrolysis to generate molecular hydrogen from the water you add — 8,000 ppb (up to 8 ppm) molecular hydrogen — 6000ppb (6 ppm) in a 10-minute cycle, 8000 ppb (8 ppm) in a 20-minute cycle.
Once the cycle finishes, you have a bottle of freshly generated hydrogen water — ready to drink at home, at work, or on the road. Research on hydrogen-rich water has studied antioxidant capacity, exercise recovery, and perceived fatigue. Results vary by person, dose, and device output.
Why this bottle
- Certified hydrogen output up to 8000ppb (8 ppm) (20-minute cycle)
- Dual-chamber SPE/PEM design to help keep chlorine and other electrolysis byproducts out of the drinking chamber
- PPSU vessel: BPA-free, BPS-free, and PFAS-free
- Independent lab review by H2 Analytics and SilverState Analytical Laboratories for hydrogen performance and heavy-metal safety
- Neutral pH — it does not make the water alkaline or acidic
- Touchscreen plus Bluetooth app to track cycles and intake
- USB-C rechargeable battery: about 5–7 ten-minute cycles or 3–4 twenty-minute cycles per charge
- 5-year manufacturer warranty from Echo Technologies
Who it’s for
The Echo Flask is for anyone who wants hydrogen-rich water as part of daily hydration — at home, at work, or on the go. Molecular hydrogen is the smallest molecule, so it dissolves into water and can move through tissues that larger compounds cannot. People use it in different ways: morning hydration, training days, travel, or an evening reset. One bottle, many routines.
Advanced Hydrogen Production The Eco Flask uses a dual-chamber SPE plus PEM (Nafion membrane) system to generate up to 8,000 ppb (8 ppm) of molecular hydrogen. This precision system creates fresh, high-purity hydrogen on demand, giving you flexibility in how you choose to use it each day.
Built for Consistent Daily Use
- Self-cleaning mode to help maintain electrode performance over time
- 2,200 mAh rechargeable battery for extended use between charges
- Lightweight and portable design that fits easily into your routine at work, at home, or while traveling
The research, in plain terms
Peer-reviewed human studies on hydrogen-rich water have reported support for antioxidant status, lower perceived exertion after exercise, and markers related to muscle recovery in trained adults. These studies used specific doses and devices. The Echo Flask is designed to deliver a high dissolved-hydrogen concentration so you can use hydrogen water as part of a daily hydration routine. It is not a medical device and is not intended to diagnose, treat, cure, or prevent disease.
