Hydrogen Water Filter

There's a common misconception that the proton exchange membrane (PEM) in hydrogen water bottles acts as a water filter. While the PEM does filter oxygen from hydrogen during the electrolysis process, it does not filter or purify the water itself. It's important to understand this distinction to avoid confusion and set realistic expectations when using hydrogen water bottles.

What is a PEM?

In a hydrogen water bottle, the PEM is a crucial component that separates the hydrogen and oxygen molecules in water during electrolysis. It allows the hydrogen gas to be collected and then infused back into the water, creating hydrogen-rich water. However, the PEM's function is not to filter or improve the quality of the water.

Hydrogen Water vs. Filtered Water

If tap water is used in a hydrogen water bottle, the PEM will not filter out impurities or contaminants. The resulting hydrogen water will simply be tap water with added hydrogen gas. To obtain purified hydrogen water, it's necessary to start with filtered or purified water before the hydrogen infusion process.

Combined Systems

Some advanced systems such as the Ocemida Ultima combine water filtration and hydrogen infusion in a single unit. These are typically larger, more complex systems rather than portable hydrogen water bottles. They first filter the water to remove impurities and then infuse it with hydrogen gas. However, these combined systems are less common and often more expensive than standard hydrogen water bottles.

What to Look for in a Hydrogen Water Bottle

When choosing a hydrogen water bottle, it's essential to understand its capabilities and limitations. If water purity is a concern, consider using filtered or purified water in your hydrogen water bottle. Alternatively, look for a device that incorporates both water filtration and hydrogen infusion.

Remember, the primary purpose of a hydrogen water bottle is to infuse water with hydrogen gas, not to filter the water. By understanding the role of the PEM and the difference between hydrogen infusion and water filtration, you can make an informed decision when selecting a hydrogen water bottle that meets your needs.
