The Quick Answer (30 Seconds)
Hydrogen water bottles work through electrolysis. When you press the button, electricity splits water (H₂O) into hydrogen and oxygen gases. The bottle keeps the hydrogen, dissolves it into your water under pressure, and vents out the oxygen. After 5-10 minutes, you have water infused with 5-8 PPM (parts per million) of molecular hydrogen. The entire process is controlled by a microprocessor and powered by a rechargeable battery.
Think of it as: how sparkling water gets its fizz. A gas, carbon dioxide, is forced into the water, creating bubbles and a tangy taste.[1] A hydrogen water bottle does something similar, but with a different gas and a different method.

Part 1: The Core Technology - Electrolysis Explained
What Is Electrolysis?
Electrolysis is the process of using electrical current to drive a chemical reaction that wouldn't occur naturally. In our bottles, we're forcing water molecules to split apart into their component gases.

Part 3: The Step-by-Step Process Timeline
Let me walk you through exactly what occurs during a typical 5-minute cycle:
- Microprocessor awakens from sleep mode
- Conductivity test confirms water presence (>10 μS/cm)
- Pressure sensor verifies sealed chamber
- LED turns blue indicating start
- Power ramps up gradually to avoid electrode shock
- First hydrogen bubbles appear at cathode
- Oxygen forms at anode (behind membrane)
- Current stabilizes at 1.0 amps
- Hydrogen production rate: 0.4ml/minute
- Pressure builds to 1.4 atmospheres
- Micro-bubbles form and dissolve continuously
- Oxygen vents through exhaust port every 20 seconds
- Temperature rises by 5-8°C (monitored continuously)
- Dissolution rate equals production rate
- Water reaches 1.2-1.6 PPM hydrogen concentration
- Bubble size reduces to optimal 50-100nm
- System maintains steady-state operation
- Current gradually reduces to prevent pressure spike
- Final oxygen purge ensures no gas mixture
- Pressure normalizes to atmospheric
- LED turns green, audible beep sounds
- System enters standby mode

Part 4: Performance Variables
Water Temperature Impact (unpressurised)
| Temperature | Efficiency | Hydrogen Output | Notes |
|---|---|---|---|
| 4°C (39°F) | 70% | 0.8-1.1 PPM | Reduced ion mobility |
| 20°C (68°F) | 100% | 1.2-1.6 PPM | Optimal performance |
| 30°C (86°F) | 95% | 1.1-1.5 PPM | Slightly reduced dissolution |
| 40°C+ (104°F) | N/A | System shuts off | Membrane protection mode |
Water Source Effects (unpressurised)
| Water Type | Conductivity | Performance | Hydrogen Output |
|---|---|---|---|
| Distilled | 50-200 μS/cm | Optimal | 1.2-1.6 PPM |
| Spring | 100-400 μS/cm | 95% | 1.1-1.5 PPM |
