Independently Lab-Tested Hydrogen Output
Every current Ocemida hydrogen water bottle is independently tested for dissolved hydrogen concentration by H2 Analytics, the IHSA-accredited testing laboratory. The Omni holds an active IHSA Certificate of Compliance valid through 2027. The Nexis is tested by H2 Analytics using gas chromatography and by H2HUBB using Unisense H2 microsensor measurement, and appears on H2HUBB's public approved-products list. Both bottles have been tested for PFAS contamination by Eurofins Environment Testing Canada.

What "lab-tested" actually means in this category
The hydrogen water bottle market is full of claims like "Certified H2 Generator," "SGS Certified," "FDA Approved," and "6,000 PPB." Most of these phrases do not refer to dissolved hydrogen measurement at all.
SGS, FDA, FCC, CE, and RoHS are real organizations that certify real things, but none of them measure how much hydrogen is actually in the water when you drink it.
There are two recognized standards bodies for measuring dissolved hydrogen in this category:
H2 Analytics
The IHSA-accredited laboratory that performs dissolved hydrogen testing using gas chromatography, the gold standard for dissolved gas measurement. Their method uses static headspace analysis on an SRI 8610C gas chromatograph with a Hayesep-D column and TCD detector, calibrated against H2-saturated water standards on the day of each test. H2 Analytics issues formal Certificates of Compliance with three-year validity, tested against standards published by the International Hydrogen Standards Association (IHSA).
H2HUBB
An independent testing service that uses Unisense H2 microsensors with UniAmp amplifiers, the electrochemical detection technology used in academic hydrogen research, capable of real-time dissolved H2 measurement with 0.02-second temporal resolution. H2HUBB maintains a public approved-products list at h2hubb.com.
The Nexis (OCE-6000 PRO)
Independently tested and verified by both H2 Analytics and H2HUBB, using two different gold-standard measurement methods.
Nexis
Professional Hydrogen Water Bottle, Model OCE-6000 PRO
H2 Analytics — Gas Chromatography
Report H2A-24030702 · March 2024H2 Analytics tested the Nexis using static headspace gas chromatography on an SRI 8610C instrument, calibrated against H2-saturated water standards on the day of testing. Three test runs per cycle were performed in distilled water at 25.4°C, with lab elevation corrected to standard atmospheric pressure (SATP).
H2HUBB — Unisense H2 Microsensor
January 2026H2HUBB's January 2026 evaluation used the Unisense H2 Microsensor with UniAmp amplifier, a laboratory-grade electrochemical detection system that measures dissolved hydrogen in real time. Each measurement was performed in triplicate with 270 mL of distilled water.
H2HUBB's evaluation confirmed no detectable chlorine and no detectable ozone in the output water, food-grade materials throughout, and no safety concerns. The full time-trace from the Unisense sensor shows the Nexis sustaining hydrogen concentrations above 7 mg/L throughout the 10-minute cycle. H2HUBB issued an official Hydrogen Performance Certificate for the Nexis and includes the bottle on the public approved-products list at h2hubb.com.
Real-world expectations: The lab measurements above reflect the bottle operating under controlled conditions with a properly conditioned PEM membrane. H2HUBB's January 2026 report notes that consumers may reasonably expect dissolved hydrogen concentrations in the range of approximately 6 to 7 mg/L on the 10-minute cycle under typical home use, with the exact figure depending on water temperature, fill volume, membrane conditioning state, and other use variables.
PFAS testing by Eurofins Environment Testing Canada (Report 3013621, January 2025) tested the Nexis output for the 11 PFAS compounds tracked by Health Canada and the US EPA. All 11 measured below 1.0 ng/L, non-detect.
The Omni (OCE-5000 PRO)
Holds an active H2 Analytics IHSA Certificate of Compliance, valid through May 2, 2027.
Omni
Hydrogen Water Bottle, Model OCE-5000 PRO
IHSA Certificate of Compliance
Registration 24-0502-1-PB · Valid through May 2, 2027The Omni holds an active H2 Analytics IHSA Certificate of Compliance, Registration Number 24-0502-1-PB, issued May 2, 2024. The certificate confirms that the Omni was tested in accordance with International Hydrogen Standards Association (IHSA) standards and US EPA Safe Drinking Water Act parameters and was found in compliance with both.
H2 Analytics — Gas Chromatography
Report H2A-24030701 · March 2024Three test runs per cycle, performed in distilled water at 25.4°C, lab elevation corrected to standard atmospheric pressure.
SGS Silver State Analytical Labs — Water Quality Panel
Workorder 24030438 · May 2024SGS ran the Omni's output through the full domestic water panel used to evaluate US EPA SDWA compliance: anions (chloride, fluoride, nitrate, nitrite, sulfate), heavy metals (lead, arsenic, cadmium, chromium, copper, manganese, nickel, selenium, silver, zinc, antimony, beryllium, barium), aluminum, boron, titanium, platinum, calcium, iron, magnesium, sodium, cyanide, hardness, MBAS surfactants, and dissolved silica. All target contaminants tested below detection limits or below SDWA Maximum Contaminant Levels.
PFAS testing by Eurofins Environment Testing Canada (Report 3013622, January 2025) tested the Omni's output for the same 11 PFAS compounds. All 11 measured below 1.0 ng/L, non-detect.
Testing methodology and limitations
The values published on this page are independent lab measurements made under controlled conditions with distilled water at 18 to 25°C and a properly conditioned PEM membrane. In real-world use, actual dissolved hydrogen output can vary based on water type (distilled water gives the highest output; tap water with high mineral content produces lower output and shortens membrane life), water temperature, membrane age and conditioning state, battery charge level, ambient atmospheric pressure, and the time elapsed between cycle completion and consumption. Dissolved hydrogen escapes from water over time even in a sealed container; drinking the water within a few minutes of cycle completion captures the highest available dose.
H2 Analytics IHSA Certificates of Compliance are valid for three years from the date of issuance and are subject to periodic recertification. The Omni certificate (24-0502-1-PB) is valid through May 2, 2027.
