When selecting a hydrogen-rich water cup, it’s essential to understand how hydrogen is added to the water. Currently, there are three main hydrogen production methods used in the market:
- Magnesium Reacts with Water: This method involves using a magnesium mineral that reacts with water to produce hydrogen. While simple and cost-effective, the magnesium is used up, requiring occasional filter element replacement. This process also generates magnesium ions, which can be complex for the body to absorb. Additionally, a large amount of hydrogen water needs to be consumed before its effects are noticeable. Due to these shortcomings, this type of hydrogen-rich water cup is not recommended.
- Ordinary Electrolysis Method: This method is widely adopted by most hydrogen-rich water cup manufacturers. Platinum electrodes are used to electrolyze water, generating hydrogen and oxygen simultaneously. However, the process also produces residual ozone and chlorine, mainly if tap water contains chlorine for sterilization. To address this, mineral particles are often added to improve taste and partially absorb the residual substances. While cost-effective, this method only partially solves the problem of residual chlorine and ozone, and the quality can vary among manufacturers.
- SPE Proton Membrane, Pure Water Electrolysis, Hydrogen, and Oxygen Separation: This method completely separates hydrogen and oxygen using SPE proton membrane electrolysis technology. Hydrogen production equipment with vent holes discharges gases other than hydrogen during the electrolysis process, enhancing the hydrogen concentration in the water. The process ensures no residual chlorine or ozone is produced, resulting in high-purity hydrogen and increased hydrogen water functionality. While some components can be expensive, this method provides a high-quality hydrogen-rich water cup.
Summary Points for Choosing a Good Cup:
- Consider the working principle: Opt for a hydrogen-rich water cup that “electrolyzes water to produce hydrogen” rather than one containing magnesium.
- Check hydrogen and oxygen separation: Choose a cup with a proton membrane that separates hydrogen and oxygen, effectively isolating ozone and chlorine.
- Test the TDS value: Use a “TDS detection pen” to ensure the cup doesn’t shed heavy metals. The TDS value should remain unchanged after continuous hydrogen production.
Q1: What’s a good hydrogen concentration? A concentration exceeding 3000PPB is ideal, supersaturation at 5000PPB, and limit saturation at 6000PPB.
Q2: Which proton membrane brand is recommended? The DuPont N117 proton membrane is a preferred choice.
Q3: How to choose the electrode sheet material? Titanium platinum material is best, as stainless steel can oxidize over time, preventing hydrogen production.
Now that you’re well-informed, you can confidently choose a hydrogen-rich water cup that suits your needs!
