What Is the Echo Flask?
The Echo Flask is a portable hydrogen water bottle that uses electrolysis to infuse regular water with molecular hydrogen (H₂). Made by Echo Water (also known as Echo Technologies LLC), it’s the successor to the popular Echo Go+ and represents the most advanced portable hydrogen water generator on the market.
What makes the Echo Flask hydrogen water bottle unique is its combination of high hydrogen output (up to 8.0 PPM) with smart technology—including Bluetooth app connectivity, a touch screen interface, and hydration tracking. It’s the first “smart” hydrogen water bottle, designed for health enthusiasts, athletes, and biohackers who want precise control over their hydrogen intake.
What Does Echo Flask Do?
The Echo Flask uses SPE/PEM electrolysis to split water molecules, infusing pure molecular hydrogen into your water while safely venting oxygen and other byproducts. The result is hydrogen-rich water with antioxidant properties that may support recovery, energy, and cellular health. Learn more about hydrogen water benefits.
Health experts like Gary Brecka and Dana White have publicly endorsed Echo Water products, bringing mainstream attention to hydrogen water benefits.
How Does the Echo Flask Work?
Understanding how hydrogen water bottles work helps you appreciate what makes the Echo Flask special. Here’s the process:
The Electrolysis Process
- 1Fill the Echo Flask with filtered or distilled water
- 2Activate a cycle via touch screen (10 or 20 minutes)
- 3Electric current passes through platinum-titanium electrodes
- 4Water molecules split into hydrogen and oxygen
- 5PEM membrane separates gases; oxygen vents out
- 6Pure hydrogen dissolves into water as nanobubbles
SPE/PEM Technology Explained
SPE (Solid Polymer Electrolysis) and PEM (Proton Exchange Membrane) technology is what separates quality hydrogen bottles from cheap alternatives. Originally developed by NASA, this technology:
- Produces pure molecular hydrogen without contaminants
- Safely separates and vents chlorine, ozone, and oxygen
- Uses platinum-coated titanium for durability
- Prevents metal leaching into your water
Warning: Cheap bottles without SPE/PEM technology may leave harmful chlorine and ozone in your water!

Echo Flask vs Echo Go Plus: What’s the Difference?
One of the most common questions in Echo Flask reviews is how it compares to the Echo Go+. Having used both extensively, here’s my breakdown of Echo Flask vs Echo Go:
| Feature | Echo Flask ⭐ | Echo Go+ |
|---|---|---|
| Hydrogen Concentration | Up to 8.0 PPM | Up to 4.5 PPM |
| Capacity | 12 oz (350 ml) | 10 oz (300 ml) |
| Cycle Time | 10 or 20 minutes | 5 or 10 minutes |
| Hydrogen Retention | 10+ hours sealed | 3-5 hours |
| Smart Features | Bluetooth App, Touch Screen | One-button operation |
| Self-Cleaning | Built-in cycle | 3-min cycle |
| Battery | 2000 mAh, 7 cycles | 1500 mAh, 5-10 cycles |
| Weight | 1 lb (455g) | 0.88 lb (400g) |
| Warranty | 5 Years | 5 Years |
| Price | $299.99 | $249.95 (Discontinued) |
| Status | Current Model | Discontinued |
My Verdict on Echo Flask vs Echo Go:
The Echo Flask is a significant upgrade in every measurable way. The nearly double hydrogen concentration alone justifies the $50 price difference. If you already own an Echo Go+, upgrading makes sense for serious users. New buyers should go straight to the Flask—the Echo Go+ has been discontinued anyway. See my full Echo Go review for more details.
