What Should You Know Before Buying A Hydrogen Water Bottle

The birth of the hydrogen-rich water cup has brought people a very portable way to absorb the healthy energy of hydrogen molecules. It is ready-to-use, simple, and easy to carry, the price is relatively moderate, and consumers are easy to accept. Therefore, decadent Hydrogen water cups have always been a top-rated product among many hydrogen health products.

Especially as the health value of hydrogen-rich water is gradually recognized and accepted by the public, more and more people use hydrogen-rich water cups—hydrogen water cups.

But a newbie who wants to buy a hydrogen-rich water cup is often at a loss when faced with the various products on the market and needs to learn how to choose.

Today, I would like to share some knowledge points about hydrogen-rich water glasses on the market. I suggest you look before buying hydrogen-rich water glasses to avoid being fooled!

Hydrogen-rich water is good, but hydrogen-rich water cups are suitable!

Many people buy hydrogen water cups because of the health-regulating effect of hydrogen molecules in hydrogen-rich water prepared from the cups. You can’t just look at the high-tech sense of the water glass or the high “appearance” of the water glass!

I want to tell people who want to buy hydrogen-rich water glasses they must remember this sentence: hydrogen-rich water is good, but hydrogen-rich water glasses are not necessarily good.

Regardless of the concentration of hydrogen water prepared in a water cup, water quality safety is paramount. After all, no matter how good hydrogen water is, it contains non-hydrogen derivatives such as ozone and hypochlorite and the precipitation of heavy metals. Do you still dare to drink it?

Most of the cheap hydrogen-rich water cups on the market adopt the solution of carrier electrolysis, and what’s more, they directly use two pieces of stainless steel sheets as the cathode and anode. Such products will be oxidized entirely after a few times of use; not only can they not continue to produce hydrogen, but they will pollute water sources, which will also bring health risks to the human body. The most prominent feature of this type of cup is that the bubbles are smoky or milk-like. Because the electrolysis efficiency is low, large bubbles are produced, so it looks white, and some have an unpleasant smell. Such cups often have deficient hydrogen concentration. Many consumers who don’t know where they only know that hydrogen-rich water is good unthinkingly and impulsively go to the Internet to search for hydrogen-rich water cups and are complacent, thinking they have made a lot of money. Still, they don’t know that they may have been sold. Pitted.

How to identify the quality of the hydrogen water cup, in addition to tasting the prepared hydrogen water for odor, here is another straightforward method!

That is, buy a TDS (total dissolved solids) detection pen (very cheap, about tens of yuan a piece, you can buy it on Taobao), fill the hydrogen water cup with water (purified water or mineral water), measure and record the concentration of the raw water TDS concentration, do not cover the cup, then press the switch for 20 times to produce hydrogen continuously, and then check the TDS concentration, if it is a good hydrogen water cup, this value should not increase if it increases more, it means that there is a lot more in the water Solids, these may be heavy metals precipitated during the electrolysis of the cup, which are harmful to the human body and are not recommended for long-term use.

The hydrogen production principle of the hydrogen-rich water cup needs to be understood because it is related to the cost of the water cup and the safety and concentration of hydrogen water!

At present, the hydrogen-rich water cups on the market can be roughly divided into three types of hydrogen production principles:

1. Entry-level hydrogen-rich water cup: hydrogen is produced by chemical methods, usually using metal magnesium

A mineral whose main component is magnesium is made through a process that utilizes the principle that magnesium reacts with water to produce hydrogen.

Equation: Mg+2H2O=Mg(OH)2+H2↑Slow reaction produces hydrogen; if hot water is used, the reaction will be strengthened.

Advantages: The hydrogen-rich water cup of this principle is simple to process and low in cost.

Disadvantage: The magnesium will be used up, so the filter element must occasionally be replaced. Moreover, this hydrogen production method will produce magnesium ions, which the body needs. Still, the human body absorbs a large amount of magnesium ions, increasing the problem’s complexity. In addition, people need to drink a lot of hydrogen water for this hydrogen production method of water cups before the effect of hydrogen is displayed.

2. Universal hydrogen-rich water cup: ordinary electrolysis method

Most manufacturers of hydrogen-rich water cups currently adopt this. Platinum electrodes are placed in water simultaneously, and hydrogen and oxygen are simultaneously generated during electrolysis and discharged into the water.

Electrode reaction formula: anode: 4OH–4e-=O2↑+2H2O, cathode: 4H++4e-=2H2↑

But the anode still has two side reactions, one of which is to generate ozone: 3H2O-6e-=O3+6H+

Another side reaction is the generation of chlorine: 2Cl–2e-==Cl2↑

Japan’s Jiangtian Hydrogen Water Cup is such an electrolytic hydrogen production method. Many consumers find that the Jiangtian Hydrogen Water Cup is not suitable for China, and there will be a peculiar smell when used in China. The peculiar smell is ozone and residual chlorine. In the final analysis, the reason is: Japan’s tap water can be drunk directly, without heavy metals and other organic pollutants, and there will be no residual chlorine. In China, chlorine gas is added to tap water for sterilization, and the chlorine content of tap water containing chlorine will increase by more than five times after electrolysis.

There is no way to avoid the generation of ozone. Therefore, in this kind of universal hydrogen-rich water cup, mineral particles are generally in it to improve the taste, and some can partially absorb residual chlorine and ozone.

If pure water electrolysis is used, the residual chlorine and ozone will be reduced accordingly. However, many cups that use the standard electrolysis method on the market cannot produce hydrogen, or the hydrogen production capacity is significantly weakened by pure water because the conductivity of pure water could be better. If you use distilled or deionized water, this kind of cup will not work at all.

Advantages: low cost, easy to popularize.

Defects: Can only partially solve the problem of residual chlorine and ozone. The threshold is low, there are many manufacturers, and the quality could be better.

3. High-end hydrogen-rich water cup: SPE proton membrane, pure water electrolysis, hydrogen, and oxygen separation

The hydrogen-oxygen separation type hydrogen water cup realizes the complete separation of hydrogen and oxygen through SPE proton membrane electrolysis technology. The hydrogen production equipment at the lower part is equipped with an exhaust hole, and gas other than the hydrogen generated during the electrolysis of the hydrogen-rich water cup is produced. It is discharged outside, thereby increasing the hydrogen concentration in the water and enhancing the function of hydrogen water on the human body.

The specific hydrogen production process is as follows:

Using a proton exchange membrane, electrocatalyst particles are directly attached to the membrane to form a membrane-electrode assembly. The membrane-electrode assembly is to embed active electrodes (catalytic substances) on both sides of the solid polymer electrolyte membrane, allowing only protons and water to pass through. When producing hydrogen, the electrolysis reaction of water is carried out on the membrane-electrode, which acts as a diaphragm and an electrode.

Water undergoes an electrolysis reaction at the anode of the power supply to generate hydrogen and oxygen. Hydrogen will lose electrons at the anode and become hydrogen ions, which can reach the cathode through the proton membrane in the form of hydration, while oxygen cannot pass through and can only be discharged. After hydrogen ions reach the cathode of the power supply, they obtain electrons from the cathode and recombine to form hydrogen gas. Oxygen is discharged from the bottom, and highly high-purity hydrogen is injected into the water.

Advantages: No residual chlorine and ozone are produced, the hydrogen produced is of high purity, and the concentration of hydrogen water is high.

Disadvantage: The SPE electrolyte membrane used can only be produced by a few foreign companies, such as DuPont, Dow, etc. Many parts of the electrolyzer are expensive, so the cost is high, and the price of the hydrogen-rich water cup is not cheap.

Although there is nothing wrong with prioritizing hydrogen concentration when choosing a hydrogen water cup, you should also distinguish the true from the false!

When many people choose hydrogen water cups, they prioritize hydrogen water cup products with high hydrogen production concentration. Indeed, the industry generally believes that the relationship between the hydrogen concentration and the effect is positively correlated. In other words, the higher the hydrogen concentration, the stronger the effect on human health. For the opinion that the higher the concentration of hydrogen in water, the stronger the effect, the industry follows that hydrogen is relatively safe, and increasing the concentration can maximize the pursuit of the ideal effect. However, there is a specific limit to the amount of drinking per person at a time. Therefore, only by increasing the hydrogen concentration in water can the hydrogen concentration in human blood be effectively increased.

At standard temperature and pressure, the saturated hydrogen solubility in the laboratory is 1.58mg/L, which we often hear as 1.58ppm=1580ppb. In real life, it is challenging to achieve saturation. Of course, the hydrogen concentration can be very high through unique processes, but this requires relatively advanced hardware and technology to achieve.

The more effective measure to increase the hydrogen concentration in water is “hydrogen and oxygen separation.” Firstly, the gas is separated, and then the gas-liquid mixing technology is used to maximize the amount of hydrogen dissolved in water. This technology is also used in the high-end hydrogen-oxygen separation hydrogen-rich water cup mentioned above.

Those very cheap, hydrogen-rich water glasses that say that the hydrogen concentration can reach or even exceed 1580ppb are unreliable, so please choose carefully.

Well, today’s popular science time is over. Finally, I would like to advise everyone, for health’s sake, don’t be greedy for cheap; cheap is not good, and this is always the truth!

Last, you’ll need to learn more about relevant professional knowledge before buying a hydrogen-rich water bottle. You will be able to buy a satisfactory hydrogen-rich water bottle!
