ECHO Flask Hydrogen Water Bottle vs Piurify Hydrogenator Bottle

Both make hydrogen-rich water with SPE/PEM electrolysis, so the real split is capacity, cycle speed and support. The Echo Flask holds 12 oz, reaches 8 ppm in 20 minutes, shows a countdown and syncs with an app and Apple Health or Android Health. The Piurify Hydrogenator runs faster cycles, claims higher peak concentration and backs the bottle with a lifetime warranty and a 60-day trial. Buy the Echo Flask for app tracking and a sturdier PPSU body; buy the Piurify to test the category with less risk.

• Choose the Echo Flask if you want app and health-app tracking, a countdown display and a 12 oz PPSU bottle for workouts and recovery.
• Choose the Piurify Hydrogenator if you want short 5- and 10-minute cycles, a lifetime warranty and a 60-day money-back trial before committing.
