Echo Flask Hydrogen Water Bottle

The ECHO Flask produces hydrogen-infused water at up to 6ppm in a 10-minute cycle and up to 8ppm in a 20-minute cycle — among the highest concentrations available in any portable format. Platinum and titanium plating on the electrolysis chamber and an advanced proton exchange membrane ensure clean, efficient hydrogen production with no pH change, no heavy metals, no BPAs, no chlorine, and no PFAs. The interactive touchscreen LCD display offers dark and light mode, while Bluetooth connectivity syncs with Apple Health and Android Health via the companion app. A built-in rechargeable lithium-ion battery delivers up to 7 cycles per charge. BPA-free shatter-proof casing, a lock-and-seal easy-twist cap, pressure release valve, and oxygen release port complete the build.

USB-C charging cable

Charging block

Fill the flask with water to the fill line. Select your cycle time — 10 or 20 minutes — on the touchscreen LCD display. The unit will infuse molecular hydrogen directly into your water during the cycle. Charge via USB-C before first use — a full charge delivers up to 7 cycles. Download the companion app and enable Bluetooth to sync with Apple Health or Android Health for goal tracking and session history. Hand wash only — do not submerge the base unit or expose the charging port to water.
