Frequently Asked Questions

Hydrogen water is regular drinking water infused with dissolved molecular hydrogen (H₂). Unlike oxygen bubbles, molecular hydrogen is an odorless, tasteless gas that can dissolve into water using advanced electrolysis technology.

Rimnahv uses advanced SPE/PEM electrolysis technology to separate hydrogen from water molecules. The hydrogen is infused back into your drinking water while oxygen is separated, producing fresh hydrogen-rich water in just 3 minutes.

SPE (Solid Polymer Electrolyte) and PEM (Proton Exchange Membrane) technology is an advanced electrolysis system that produces high-purity molecular hydrogen while separating oxygen and unwanted byproducts. It is one of the most efficient methods for creating hydrogen-rich water.

A complete cycle takes approximately 3 minutes, producing fresh hydrogen-rich water ready to enjoy.

The bubbles are molecular hydrogen being generated during the electrolysis process. This is a normal part of the hydrogen infusion cycle.

Yes. Molecular hydrogen is naturally produced in the human body and has been studied for decades. Rimnahv bottles create hydrogen-rich water using only water and electricity — without chemicals or additives.

No. Hydrogen is colorless, odorless, and tasteless, so your water will taste like the water you put into the bottle.

For the best performance, use filtered or purified drinking water. Avoid carbonated beverages, juices, milk, or sugary drinks.

No. Rimnahv bottles are designed specifically for drinking water. Using other liquids may affect performance and shorten the life of the electrolysis system.

There is no required amount. Many users enjoy hydrogen water throughout the day as part of their normal hydration routine.

Hydrogen gradually dissipates over time. For the best experience, drink your hydrogen water shortly after the generation cycle finishes.

A full charge typically provides up to 15 hydrogen generation cycles, depending on usage and operating conditions.

Simply connect the included USB charging cable to the bottle and a compatible power source until fully charged.

Yes. Rimnahv bottles are lightweight, rechargeable, and designed for use at home, at work, in the gym, or while traveling.

Rinse the bottle with clean water after use. Clean the interior regularly with warm water and a mild soap if needed. Do not submerge the charging port or electrical components in water.
