How does SPE PEM electrolysis work in this bottle?

It splits water with electricity across a proton exchange membrane, releasing hydrogen gas into the water while venting oxygen and ozone separately. This is the same approach used in most portable hydrogen bottles.

Does hydrogen water actually have health benefits?

Small studies suggest possible antioxidant effects, but evidence is limited and not conclusive. Treat the health claims as unproven rather than established.

How long does the hydrogen stay in the water?

Concentration drops over time, so drink the water soon after a cycle finishes. Leaving it sitting for hours loses much of the hydrogen.

What water should I put in it?

Use clean drinking water. Mineral-heavy or very hard water can scale the membrane and shorten the bottle's life, so filtered water is a safer choice.

How does it compare with a countertop hydrogen ionizer?

Countertop units produce more hydrogen-rich water per session and often add filtration, but they stay in one place. This bottle is for small amounts made anywhere.

How do I clean and maintain it?

Rinse the chamber after use and let it dry with the cap off. Follow the maker's instructions for descaling, since mineral buildup is the main cause of weak output.
