Usage Frequently Asked Questions

A1. Our machine uses pure water electrolysis technology to produce molecular hydrogen without adding any chemical substances to produce high-purity molecular hydrogen. Usable commercial water brands, including Taishan pure water or UNI water, are stable and reliable. The reason for not recommending the use of household filtered water is that it is impossible to confirm whether the filtered water at each user's home meets the requirements of the machine. If it does not, it will seriously affect the lifespan of the core, so please be careful, making sure the water added is pure enough.

A2. Commercially available purified water is not specifically designed for hydrogen generators; it simply meets the machine’s basic water quality requirements. To maintain optimal hydrogen-production performance, an additional filter cartridge is installed to further purify the water.

A3. The filter cartridge is made from resin produced by DuPont (USA). Its primary function is to further adsorb and remove ions from purified water, helping maintain the performance of the hydrogen-generation core.

A4. The cover on the top serves as a dust cap, and the opening it covers is the oxygen vent. When the hydrogen generator electrolyzes purified water, it produces not only hydrogen but also oxygen. The oxygen is released through this upper vent, so the cap must be removed during operation to allow proper oxygen discharge. If the oxygen cap is not removed, the machine will be unable to vent oxygen properly, causing water inside the unit to be pushed out through the hydrogen outlet and into the nasal cannula. In this case, remove the oxygen cap, shake out any water from the nasal cannula to prevent airflow blockage, and then reconnect it to the hydrogen generator before use.

A5. Because hydrogen gas is colorless and odorless, there is usually no noticeable sensation during hydrogen inhalation. If a user is concerned about whether hydrogen is being inhaled, the nasal cannula can be placed in water; the presence of bubbles indicates that hydrogen is being produced normally.

A6. Due to the physical properties of hydrogen gas, it naturally moves toward areas of lower pressure. If the two outlets of the nasal cannula are not positioned evenly in the water and are at an angle, the water pressure on each side will differ. As a result, hydrogen may flow through the side with lower water pressure, causing bubbles to appear from only one outlet. This is a normal phenomenon and does not affect use.

A7. It is recommended to replace the nasal cannula once a month to ensure proper hygiene.

A8. After removing the nasal cannula, gently shake it a few times to expel the water droplets inside. You can also blow air through the connector end of the cannula, or use a standard air pump available in general stores to blow out the remaining water droplets.

A9. Under normal use, the water in the nasal suction tube and the water collection vial is formed by condensation of the cold water vapor. Usually, it takes several hours to accumulate slowly. If the user finds that the hydrogen molecule's exhaust vent is accompanied by water dripping out, it may be due to (1) the cover on the water plug has not been removed, or (2) too much water has been added.

A10. When the machine overheats, first check that there is sufficient space at the rear of the unit for proper heat dissipation. Next, confirm whether the ambient temperature is too high. If both factors are ruled out and the overheating issue persists, the machine will need to be returned to the factory for inspection and repair.

A11. An airflow blockage warning indicates that the produced hydrogen cannot flow smoothly to the user’s nasal cavity. In this case, first check whether the water level in the water collection vial is close to full; if so, empty the water. Next, inspect the nasal cannula for excessive water droplets. If present, refer to Point 8 and remove the water from the nasal cannula.

A12. After every 500 hours of use, the indicator window will flash a blue light to remind you to replace the filter cartridge. The machine can still operate normally at this time, but the filter should be replaced as soon as possible to ensure optimal performance of the hydrogen-generation core. After replacing the filter, press and hold the power button to reset the timer; the blue flashing light will then stop. When replacing the filter cartridge, it is not necessary to drain the remaining purified water inside the machine. Simply install the new filter and refill purified water up to the MAX line, and the machine can be used again.

A13. Please make sure the hydrogen gas connecting tube and the signal cord to the water cup are properly connected before turning on the main hydrogen generator. Once the hydrogen mix bottle starts producing bubbles, press the power button on the bottle to begin mixing. If the hydrogen generator is already powered on and the signal cord is connected afterward, a short circuit may occur and cause a malfunction. Do not allow the mix bottle, signal cord, or base to come into contact with water, as this may result in a short circuit and prevent normal operation. After pressing the power button, the hydrogen mix bottle will automatically stop after two minutes. The hydrogen-rich water is then ready to drink.

A14. Yes. The hydrogen mix bottle is made of food-grade PC material and is heat-resistant up to 120°C.

A15. Yes. Any beverage without solid particles can be poured into the blender cup, such as milk, juice, or alcohol.

A16. Yes. However, be sure to remove the base and the blender cup power cable, and wash only the blender cup itself.

A17. Dialysis-grade purified water can be used. Reverse osmosis (RO) water is not recommended, as it may still contain trace minerals and silicates. The purified water used in the hydrogen generator should have an electrical conductivity of below 5 μS/cm.

A18. Based on our experience, with 3–4 hours of daily use, the machine typically needs to be refilled only once every 1–2 weeks. (The refill frequency may vary slightly depending on ambient temperature, humidity, and usage conditions.)

A19. The labeled service life is a regulatory requirement. In practice, as long as the filter cartridge is kept dry and does not come into contact with water, it can be stored for several years. (We recommend storing it in a sealed zip-lock bag.)

A20. Molecular hydrogen is produced through the electrolysis of purified water. Because the core electrolyzes pure water, the purity of the molecular hydrogen does not decrease over time. However, as the core ages, the molecular hydrogen output may gradually decline during the later stages of the core’s lifespan. The sixth-generation core of the hydrogen generator has a rated lifespan of 5,000 hours (laboratory data). In actual operation and testing, the core lifespan can reach 7,000 hours or more.

A21. No indicator light will turn on. The core can operate for more than 5,000 hours. With regular use, our new-generation core can exceed this duration, typically lasting around six to seven years. How do you know when the core needs replacement? Simply observe the gas-generation window. If the hydrogen output becomes noticeably reduced, please return the unit to the original manufacturer for servicing and core replacement, which is more cost-effective than purchasing a new machine. If a newer generation of the machine is available at that time, you may decide whether to upgrade to a new unit based on your usage conditions.

A22. There is no need to unplug the machine. The unit performs background hydrogen generation once every hour as a self-protection mechanism for the core, lasting about one minute. During this 1-minute background process, the power consumption is approximately 20 W, while during the remaining 59 minutes, the consumption is about 1 W.
Power consumption per hour: 20 × (1/60) + 1 × (59/60) = 1.31 watt-hours (Wh)
To consume 1 kilowatt-hour (kWh) of electricity: 1000 ÷ 1.31 ≈ 763 hours
This means the machine would need to remain plugged in and on standby for about 763 hours—roughly one month—to consume 1 kWh of electricity.

A23. The function of the water collection vial is to collect excess moisture from the hydrogen gas at the outlet, ensuring that the inhaled hydrogen gas remains dry. If the water collection vial is not used, the hydrogen gas inhaled through the nasal cannula will be more humid.

A24. Materials that are more likely to release microplastics are PE and PP, which are not used in this product. The hydrogen mixing bottle is made of food-grade PC (polycarbonate) and is heat-resistant up to 120°C. Please feel confident using the hydrogen mixing bottle.
