Hydrogen water has been getting a lot of attention lately—not just because it tastes clean and refreshing, but because many people believe it can support overall wellness. If you’ve just picked up a hydrogen water bottle, one of the first questions that usually comes up is: What kind of water should I actually be using?
Before answering that, it helps to understand what hydrogen water is in the first place.
What Exactly Is Hydrogen Water?
Put simply, hydrogen water is regular water with extra dissolved molecular hydrogen (H₂). It’s a tiny molecule, and some early research suggests it may help reduce oxidative stress and support energy levels. People who drink it often want to know how soon they’ll feel anything—some notice changes quickly, others not at all. “How long does it take to feel the effects?” If you're curious, here’s a detailed explanation.
But the real key question is how the hydrogen even gets into the water, especially when using a bottle like the PUREPEBRIX® H8000.
How to Produces Hydrogen Water?
The H8000 uses a PEM (proton exchange membrane) electrolysis system. It separates water into hydrogen and oxygen, but the membrane also acts as a filter so unwanted byproducts—things like chlorine or nitrogen—are pushed out through a small exhaust port at the bottom.
This design keeps the hydrogen levels stable while preventing impurities from drifting into the drinking chamber. Because the internal components need to be precise and durable, bottles like the H8000 usually cost a bit more than generic devices, but they perform better and last longer.If you want to explore electrolysis in detail, you can check our deep-dive article here
So, What Water Should You Use?
People usually rely on four main options, and each behaves differently inside a hydrogen generator.
1. Distilled Water (Best Overall)
Distilled water has no minerals, so it doesn’t leave behind scale. It’s very easy on the electrolysis module and makes cleaning almost effortless—typically just a quick rinse and brush once a week. If you want the cleanest operation and longest device life, this is the top pick.
2. Purified or RO Water
Reverse-osmosis or purified water also works great. It contains very few minerals, so it produces almost no scale and is widely available. Many users stick with this for convenience.
3. Tap Water
Tap water varies a lot depending on where you live. The H8000’s membrane can vent chlorine and nitrogen, so the drinking chamber stays protected, but you’ll need to clean the bottle more often. If you rely on tap water, expect to brush out mineral buildup every couple of days.
4. Mineral Water
Mineral water is safe to use, but the added calcium and magnesium tend to build up faster at the bottom of the bottle. The H8000 can handle it, but you’ll want to clean it as frequently as you would with tap water.
Cleaning Recommendations
| Water Type | Suggested Cleaning | Notes |
|---|---|---|
| Distilled | Weekly | Easiest, almost no scale |
| RO / Purified | Every 3–5 days | Light film possible |
| Tap | Every 2–3 days | Minerals depend on local supply |
| Mineral | Every 2–3 days | Builds scale fastest |
As long as you stay on top of cleaning, even tap and mineral water won’t significantly shorten the life of the H8000.
Final Thoughts
If you want the highest purity and the least maintenance, stick with distilled water. RO or purified water is a close second and works perfectly fine for daily use. Tap and mineral water are still usable, but they require more cleaning.
Choosing the right water doesn’t just affect flavor—it helps your hydrogen bottle run efficiently and keeps the hydrogen levels consistent every time you use it.
