If you're considering an Echo Water hydrogen water bottle, you might be wondering about the difference between the Echo Flask and the discontinued Echo Go+. In this comparison, I'll break down everything you need to know—including why the Go+ has been discontinued and why the Flask is the clear choice.
Important Note
The Echo Go and Echo Go+ have been discontinued. They have been replaced by the Echo Flask, which is the successor model with significantly upgraded features. You can no longer purchase the Go+ new.
Echo Flask vs Echo Go+: Quick Verdict
Echo Flask Wins On:
- 78% more hydrogen (8.0 vs 4.5 PPM)
- Smart app with Bluetooth
- 10+ hour retention (vs 3-5 hours)
- Larger capacity (12 oz vs 10 oz)
- Touch screen interface
The Comparison:
- Both have 5-year warranty
- Both use SPE/PEM technology
- Both are FSA/HSA eligible
- Both have self-cleaning cycles

Echo Flask vs Echo Go+: Detailed Breakdown
Hydrogen Concentration (PPM)
The Echo Flask produces up to 8.0 PPM—nearly double the Echo Go+'s 4.5 PPM. In a 10-minute cycle, the Flask delivers 6.0+ PPM vs the Go+'s ~3.0 PPM.
This is a massive difference. More PPM means more molecular hydrogen per serving, which research suggests delivers greater antioxidant benefits. If you're serious about hydrogen therapy, the Flask's output is in a different league.
Clinical Insight: The 8.0 PPM from the Flask puts it in the "high-dose" range that recent studies associate with superior outcomes for reducing oxidative stress.
Smart Features & App
The Echo Flask includes Bluetooth app integration and an LCD touch screen. The Echo Go+ has no smart features—just basic LED indicators.
The Flask app lets you:
- Track hydration and cycle history
- Customize cycle lengths
- Receive maintenance reminders
- Get firmware updates
- Integrate with Apple Health and Google Health
If you want data-driven hydration and smart features, the Flask is your only option.
Hydrogen Retention
The Echo Flask retains hydrogen for 10+ hours when properly sealed. The Echo Go+ retains hydrogen for 3-5 hours.
This is a 2-3x difference. With the Flask, you can make hydrogen water in the morning and drink it throughout the day with meaningful H₂ concentrations still intact. With the Go+, you'd need to make fresh water multiple times daily.
Capacity
The Echo Flask holds 12 oz (350 ml). The Echo Go+ holds 10 oz (295 ml).
The Flask gives you 20% more water per fill, which means fewer refills throughout the day.
Price
The Echo Flask costs $299.99. The Echo Go+ originally sold for $229.00—but it's discontinued.
Yes, the Flask is $70 more. But for that extra investment, you get: 78% more hydrogen, smart app integration, 2-3x longer hydrogen retention, and 20% more capacity. The value is clear.
"I used the Echo Go+ for two years before upgrading to the Flask. The difference is night and day. I was getting maybe 3 PPM in my morning water by the time I drank it. Now I make water at 8 PPM and drink it 6 hours later at still over 5 PPM. The retention alone makes the Flask worth it."
— Daryl Stubbs, RMT, CAT(C), Holistic Nutritionist
Why Was Echo Go+ Discontinued?
Echo Water discontinued the Go+ because the Flask represents a significant technological upgrade:
- Higher output: 8.0 PPM vs 4.5 PPM (nearly double)
- Smart features: First Echo bottle with app integration
- Better retention: 10+ hours vs 3-5 hours
- Larger capacity: 12 oz vs 10 oz
The Flask essentially makes the Go+ obsolete. Echo Water made the right call replacing it with a genuinely superior product.
The Research on PPM Differences
The difference in PPM between these bottles has clinical significance:
"Studies indicate dose-dependent effects of hydrogen water—higher concentrations may provide more pronounced antioxidant effects. Concentrations above 3.0 PPM showed better outcomes in reducing oxidative stress markers." — Li et al. (2024), Journal of Hydrogen Research
PMID: 38590828
Summary
Echo Flask Advantages
- 8.0 PPM — highest in portable bottles
- Smart app with Bluetooth
- 10+ hour hydrogen retention
- 12 oz capacity
- Touch screen interface
- 5-year warranty
Echo Go+ Status
- Discontinued — no longer sold
- Lower PPM (4.5)
- No smart app
- 3-5 hour retention
- 10 oz capacity
- Hard to find (if at all)
Final Verdict: Echo Flask vs Echo Go+
The Echo Flask wins decisively. It's newer, more powerful, and has features the Go+ never offered. Since the Go+ is discontinued anyway, the choice is simple.
If you're upgrading from a Go+, you'll experience nearly double the hydrogen output and game-changing retention. If you're new to Echo Water, the Flask is the obvious choice.
