With hydrogenated water becoming a major wellness trend, I’ve been testing different hydrogen generator bottles with various types of water to see what works best. Through hands-on experience, I’ve noticed that the right water source can make a BIGGER DIFFERENCE than most people expect—affecting both hydrogen retention and overall effectiveness.
In this article, I’ll share what I’ve learned about the best types of water to use in hydrogen water bottles, breaking down how each choice impacts both the quality of the drink and the overall hydration experience. So, let’s begin!
Suitable Water Sources For Hydrogen Water Bottles
You probably already know that hydrogen water generators are different from regular water bottles. They contain a specialized electrolytic module that carries out electrolysis to generate molecular H2 gas, which is then infused into the drink.
These components are electrochemically sensitive, and using the wrong type of water can lead to malfunctions, damage the device, or even cause adverse reactions that make it unsafe to drink. This brings us to the question of COMPATIBILITY—so let’s explore which type of water work best with hydrogen water bottles.
A. Tap Water
The first ‘compatible’ water source that comes to mind is tap water. It’s generally safe, has a neutral pH of 7 (ideal for the electrolytic components in my bottles), and I use it with most of my hydrogen water bottles.
However, tap water quality varies by region. In some areas, it may contain toxins and impurities like chlorine, which can react differently during electrolysis, leading to unwanted byproducts and compromising the quality of hydrogen water. Make sure to utilize water within a TDS range of 50-300 ppm.
Most hydrogen water machine manufacturers specify suitable sources in their user manuals to ensure safety and effectiveness. Many recommend using purified tap water that’s free from impurities, making it a cost-effective and convenient option.
B. Filtered/ Purified Water
In addition to filtered tap water, you can also use bottled or purified water, typically processed through Reverse Osmosis (RO). RO water is largely free of unwanted minerals and contaminants, making it a clean and safe base for generating molecular hydrogen.
For optimal performance, it’s essential to utilize only regular tap water or filtered water with a neutral pH of 7. These water supplies are best suited for hydrogen machines, ensuring the electrolysis process functions properly, produces the highest possible concentration of molecular H2, and helps maintain the longevity of the device. Here’s how to test it.
Incompatible Water Sources
The following water supplies are generally considered ‘incompatible’ with hydrogen water bottles. While some manufacturers may approve certain types, I STRONGLY DISAGREE—you should never use these for making hydrogen water. Here’s why.
1. Alkaline Water Or Ionized Water
Alkaline and ionized water are technically different, but both are incompatible with hydrogen water bottles. Their high mineral content and elevated pH can interfere with the electrolysis process, clog the electrodes, and potentially reduce hydrogen infusion, ultimately affecting the quality of the hydrogen-rich water.
If you’re interested, here are detailed comparisons:
2. Bottled ‘Spring Water’
If your bottled water is labeled as ‘spring’ water, keep in mind that it typically contains naturally dissolved salts like magnesium, calcium, and sodium.
While these salts aren’t toxic, they can cause SCALING inside your hydrogen water generator, especially on the electrodes, over time, reducing its efficiency. If you can’t avoid using spring water, be sure to clean your bottle regularly and thoroughly to maintain optimal performance.
3. Carbonated Water
Bottled ‘carbonated’ water should also be avoided at all costs. Carbonated water contains dissolved carbon dioxide, which can interfere with electrolysis, leading to unexpected reactions and unwanted byproducts that compromise the quality of the resulting hydrogenated water. It’s fine to drink carbonated water as usual, but avoid using it to produce hydrogen water.
4. Distilled Water
Contrary to what many manufacturers claim, we should NEVER use distilled water to produce hydrogen gas in our bottles. While distilled water isn’t poisonous, it’s completely stripped of essential minerals that our body needs, which can be detrimental to our health in the long term.
Additionally, it tastes bland compared to regular drinking water. Ultimately, there’s no point in aiming for optimal hydration if we’re depriving our body of essential minerals. So, please avoid using distilled water in your hydrogen water bottles.
Can You Pour Hydrogen Water Into Another Bottle After Generation?
Yes, you can certainly transfer hydrogen water to another bottle after it’s been generated, but this will only speed up the dissipation of the H2 gas.
As we know, molecular hydrogen is an extremely VOLATILE gas that’s barely soluble in water. Even after infusion, it continues to escape into the air. Simply transferring it to another container, stirring it, or even disturbing the water slightly can trigger rapid dissipation. For this reason, I recommend drinking it directly from the bottle where it’s produced within a few hours to maximize its concentration and benefits.
If you must transfer it, make sure to store it in an airtight bottle or thermos flask, filling it to the brim to retain some of the dissolved hydrogen.
Cold Or Hot Water: What Should Be The Ideal Operating Temperature?
Nothing beats the satisfaction of drinking cold water on a hot summer day after an intense workout. And when you know you can prepare hydrogenated water, it doubles the satisfaction!
Yes, you source use cold water in your bottle, but the temperature should not go below 1°C. However, colder water may amplify the ozone odor produced during electrolysis, which can be off-putting.
On the other hand, if you’re considering using hot water to prepare hydrogenated water, check the user manual for the recommended operating temperature. Generally, avoid using water hotter than 60°C, and some bottles may allow up to 80°C. Keep in mind that while you wait for it to cool down, much of the dissolved hydrogen gas will have escaped.
Based on my experience and experiments with hydrogen water bottles, the ideal water temperature is between 10°C and 30°C. Room or body temperature is perfect since it creates a higher concentration of molecular H₂ and ensures the safety and longevity of the bottle.

What Type Of Water Do I Prefer For My Hydrogen Water Generators And Why?
Since you asked, let me share that I’ve been using clean and safe tap water almost 98% of the time, and I’ve never had a bad experience. I’ve tried over 20 hydrogen water bottles from different brands, and aside from one or two, most of them work really well when filled with tap water.
Initially, I wasn’t sure about the best water sources. I experimented with RO water, purified water, and bottled water labeled as ‘mineral water.’ After several trials (and a few damaged bottles), I discovered that tap water (100-200 ppm TDS) gives me the best hydrogen concentration. It’s not only great for the health of my hydrogen water bottles but also much easier to maintain due to significantly less plaque buildup.
Of course, tap water is cost-effective, easily accessible, and super convenient, which has been a key factor in helping me stick with my hydration journey for so long!
However, you should read the user manual in the box to find out the recommended water source for your hydrogen water machine (but stay away from the ones I’ve mentioned). This will help you reap the maximum benefits of your hydration regime without compromising your safety.
I was wondering if well water can be used?
It should, as long as it drinkable directly. I would recommend to test its TDS and ensure it is within 300 ppm. Hydrogen water generators function better with low TDS.
