H2Grail Hydrogen Water Bottle Review & Test Results

The H2Grail hydrogen water bottle, model HPW-200, is a compact high concentration hydrogen water bottle designed around a 200 mL serving. It combines pressure-assisted PEM/SPE electrolysis, five- and ten-minute operating cycles, a food-grade Tritan water chamber, USB-C charging, a manual pressure-release valve, and a separate bottom port for oxygen and other anode gases.

Independent H2HUBB testing using H2Blue® reagent measured an average dissolved-hydrogen concentration of approximately 3.60 mg/L after ten minutes. H2HUBB performed a minimum of eight measurements and averaged the results after converting the dissolved-hydrogen readings to SATP.

The tested 200 mL serving contained approximately 0.72 mg of dissolved H₂, equivalent to approximately 8.74 mL of dissolved hydrogen gas. Because of the bottle’s smaller capacity, H2HUBB recommends the ten-minute cycle rather than the shorter five-minute setting.

One ten-minute bottle delivers approximately 0.72 mg of dissolved H₂. Two bottles deliver approximately 1.44 mg, while three bottles deliver approximately 2.16 mg. Customers should consider the total dissolved-hydrogen dose and number of bottles consumed rather than evaluating concentration alone.

H2HUBB testing found no detectable chlorine or ozone and no increase in water pH under the evaluated conditions. Based on its verified concentration, dissolved-hydrogen dose, contamination results, construction, pressure-release design, and general operation, the H2Grail bottle received the H2HUBB Seal of Approval.

Approximate Hydrogen Dose per Bottle

Based on the independently measured ten-minute result in the tested 200 mL bottle:

• 10-Minute Average: Approximately 3.60 mg/L
• 10-Minute H₂ Dose: Approximately 0.72 mg per bottle
• Equivalent Dissolved Gas Volume: Approximately 8.74 mL H₂
• Two Bottles at 10 Minutes: Approximately 1.44 mg of dissolved H₂
• Three Bottles at 10 Minutes: Approximately 2.16 mg of dissolved H₂
• Four Bottles at 10 Minutes: Approximately 2.88 mg of dissolved H₂

Manufacturer Claim Comparison

H2Grail previously advertised approximately 2.5 mg/L after five minutes and up to 5.0 mg/L after ten minutes. The published H2HUBB evaluation did not confirm the 5.0 mg/L ten-minute claim. H2HUBB measured an average of approximately 3.60 mg/L during the tested ten-minute cycle.

The independently measured result still represents high-concentration hydrogen water and exceeds ordinary atmospheric hydrogen saturation. Publishing the measured average gives customers a more realistic expectation of repeatable performance than relying on the highest advertised figure.

Independent Test Procedure

For the H2HUBB evaluation, the bottle was filled with distilled water slightly below the bottom of the threads and above the marked maximum water line. The lid was secured, the ten-minute setting was activated, and a minimum of eight H2Blue measurements were performed and averaged. The final results were converted to SATP.

Actual dissolved-hydrogen concentration may vary with water temperature, fill level, headspace, battery charge, membrane condition, lid seal, source water, cycle selection, scaling, maintenance, pressure release, and the amount of time between cycle completion and consumption. Drink the hydrogen-rich water promptly after opening to reduce dissolved-hydrogen loss.

Important Hydrogen Inhalation Limitation

The manufacturer package includes an inhalation tube. H2HUBB does not recommend using this or any hydrogen water bottle as a hydrogen inhalation device. Its gas-production rate is far below the amount normally required to provide the inhaled-hydrogen concentrations used in scientific studies or delivered by purpose-built hydrogen inhalation equipment.

The H2Grail bottle should be used for its intended purpose: generating hydrogen-rich drinking water. Customers interested in hydrogen inhalation should use equipment specifically designed and tested for that application.
