The Science of Molecular Hydrogen
Molecular hydrogen (H₂) is the smallest molecule in nature and moves easily across cell membranes. In a bath, H₂ is absorbed through the skin rather than the digestive system, reaching skin, joints, and muscles directly.
Turn Your Bathtub Into a Molecular Hydrogen Therapy Session.
The Lumati Hydrogen Immersion Generator infuses your bathwater with 2,840 to 3,410 PPB of third-party tested molecular hydrogen, absorbed through the skin as you soak.

& immersion.
Drinking hydrogen-rich water delivers H₂ through the digestive system. Immersion delivers it through the skin across the whole body at once, which is why many people use both. The Lumati Immersion Generator produces 2,840 to 3,410 PPB of molecular hydrogen via anode pure water electrolysis, infusing your bathwater as you soak.
- H₂ is the smallest known molecule and crosses cell membranes other antioxidants cannot
- Selectively targets reactive hydroxyl radicals without disrupting beneficial signaling
- Transdermal route reaches joints, muscles, and skin at the same time
Connect & Activate
Connect the inlet assembly hose through the pressure regulator and filter to the machine's water fill inlet. Fill the internal 2.8L tank using 6L of pure distilled water only (TDS ≤ 5 ppm). Press and hold the power button to activate auto-fill. Machine stops automatically when full (E4 indicator).
⚠ Never use tap or mineral water, it will damage the membrane and void the warranty.
Fill Your Tub & Power On
Fill your bathtub with warm water (5 to 50°C / 41 to 122°F). Place the nano bubbler head in the tub, run the outlet hose, and power on the machine. Operate in a well-ventilated bathroom with a window open and exhaust fan running. The machine produces 400W of electrolysis output, keep away from open flames at all times.
Soak
Take a bath and soak for a minimum of 15 minutes. Most users soak 20 to 30 minutes. Molecular hydrogen absorbs through the skin, supporting the body's antioxidant defenses and a healthy inflammatory response from the outside in.* For best results, use 3 to 5 times per week consistently.
Frequently asked questions.
Use only pure distilled water with a TDS of ≤ 5 ppm. For the initial fill, use 6L. For a top-up when the E1 (low water) indicator appears during use, add 3L. Mineral water, tap water, or filtered water with minerals will damage the electrolysis membrane and void the warranty. The machine will display the E3 error code if water quality is too poor, drain and refill with distilled water, cycling 3 times to flush.
Drinking hydrogen-rich water delivers H₂ primarily through your digestive system. Immersion delivers molecular hydrogen transdermally, through your skin, allowing absorption across your entire body simultaneously. This provides broader systemic exposure that's especially beneficial for joint, muscle, and skin health. The two methods complement each other and can be used together as part of a complete H₂ protocol.
A minimum of 15 minutes is recommended to allow adequate transdermal absorption of molecular hydrogen. Most users soak for 20 to 30 minutes for a full session. For best results, use consistently 3 to 5 times per week. Cumulative, consistent use over weeks produces the most noticeable outcomes.
Yes, this is normal and expected. Some carbon monoxide and smoke detectors are sensitive to hydrogen gas, which can cause a false alarm. This does not indicate a safety hazard. Always operate in a well-ventilated bathroom: open a window and run your exhaust fan. Do not use the machine in enclosed, unventilated spaces.
The machine uses voice prompts and indicator lights to communicate error states:
E1, Low water. Add 3L of distilled water immediately.
E2, Overheating. Shut down and rest for 30 minutes before resuming.
E3, Poor water quality. Drain fully, refill with distilled water, cycle 3 times.
E4, Tank full. Stop adding water; resumes automatically.
E5, Water temperature too low. Drain some water, add warm water.
E6, Water outlet blocked. Check for debris and clear the blockage.
E7, Insufficient water flow. Check whether the water inlet is blocked.
Monthly: Fully drain the water tank, then refill with 6L of fresh distilled water. Before transporting: Always drain completely before moving, remove the drain plug, attach the drainage pipe, drain fully, then reinstall the plug. Never tilt or invert the machine. If the TDS indicator lights up during a fill, drain and repeat the 6L distilled fill procedure.
Yes, molecular hydrogen is highly flammable. Always operate in a well-ventilated area with open windows and an exhaust fan. Never use the machine near open flames, candles, sparks, or heat sources. Do not smoke or vape while the machine is plugged in. If you detect any unusual smell, heat, or noise, turn off and unplug the unit immediately. Keep out of reach of children.
Safety & Precautions
Molecular Hydrogen Safety
Hydrogen gas is highly flammable. Keep away from open flames, heat sources, and ignition sources.
- Use only in well-ventilated spaces, open a window and run exhaust fan
- Do not use near open flames, candles, sparks, or heat sources
- Do not smoke, vape, or use electronic devices while plugged in
- Turn off and unplug immediately if you detect unusual smell, heat, or noise
- May trigger false carbon monoxide detector alarms, this is normal
- Keep out of reach of children
Water Quality
Use only pure distilled water (TDS ≤ 5 ppm). Mineral water will damage the machine and void warranty.
Environment
Operate indoors at room temperature 40 to 104°F (5 to 40°C). Outside this range may cause malfunction.
Handling
- Do not tilt or invert, always drain fully before moving or storing
- Do not place any objects or liquids on the machine
- Do not repair or disassemble without written approval, voids warranty
