What the H2Xagen does—and what it does not do
It creates hydrogen-rich water
The generator uses electrolysis to introduce dissolved molecular hydrogen into the water already in the bottle.
It is not a water filter
It does not remove contaminants, hardness or dissolved solids. Always begin with clean, potable drinking water.

How to use your H2Xagen
-
1Fill
Add potable water to just below the upper screw thread. Do not overfill.
-
2Secure
Fit the lid correctly before starting the generator.
-
3Select a cycle
Press and hold the power button for the five-minute cycle; use the control to select the ten-minute cycle when required.
-
4Drink promptly
When the cycle finishes, open the lid carefully and drink soon afterwards because dissolved hydrogen disperses over time.
Protect the generator and battery
These simple habits help keep the bottle operating correctly.
Keep the membrane wet
Do not allow the generator membrane to dry out. Leave a small amount of water in the unit when it is not being used.
Charge correctly
Use a standard 5V/2A USB supply as instructed by Osmio. Do not use higher-voltage or fast-charging outputs.
Keep electrics dry
Do not submerge the generator or allow water into the button or USB-C charging port. Never operate it while charging.
Release the pressure
Do not run more than one ten-minute cycle without opening the lid and releasing the accumulated pressure.

Read the operating instructions before first use. The linked laboratory report records screening and migration results for the submitted sample under the stated test methods; it is not a medical or performance certification.
A balanced note about hydrogen water
Research into hydrogen-rich water is still developing. The H2Xagen is designed to make hydrogen-rich drinking water; it is not intended to diagnose, treat, cure or prevent any medical condition. Speak to a qualified healthcare professional for personal health advice.
Frequently asked questions
Does the H2Xagen filter the water?
No. It adds dissolved molecular hydrogen but does not remove contaminants or soften water. Use potable drinking water only.
Should I choose the five or ten-minute cycle?
Both cycles generate hydrogen-rich water. The ten-minute setting provides a longer generation cycle. Follow the user manual and do not run consecutive ten-minute cycles without opening the lid to release pressure.
Can I use hot water?
Use potable water at no more than 60°C. Do not exceed the manufacturer's maximum temperature.
Can I use a fast charger?
No. Use a standard 5V/2A USB supply as set out in the instructions, and disconnect the charging lead after no more than approximately 4.5 hours.
How should I store the bottle?
Keep a small amount of water in the generator so that the membrane does not dry out, while keeping the button and USB-C port dry. Refer to the manual for cleaning and longer-term storage instructions.
