H2 Nano Premium-280 Hydrogen Water Generator

2025 version — manufactured since spring 2025. Compared to the H2 Nano Premium 2-210 model, this version features an increased cup volume of 280 ml.

According to our measurements using methylene blue drops with colloidal platinum, in the 10-minute mode the hydrogen concentration ranged from 4.5 to 5.9 mg/L. The obtained values did not differ from those measured with the same device equipped with a 210 ml cup.

Thus, consuming one cup of water provides approximately 1.26–1.59 mg of molecular hydrogen.

More precise measurements performed by gas chromatography at the reputable H2 Analytics laboratory (USA) showed a concentration of 5.14 mg/L. Accordingly, drinking 270 ml of hydrogen water produced by this device delivers approximately 1.38 mg of hydrogen. It is generally recommended to consume at least 3 mg of hydrogen per day to achieve a therapeutic effect. Increasing the intake does not pose a risk of overdose, as hydrogen dissolved in water is considered safe.

H2 Nano Premium 2-280 is a portable device designed to enrich water with high concentrations of molecular hydrogen for home use.
