Zontos Z3 Hydrogen Water Generator Review, Test Results & Price
$4250
Description :
This Zontos Z3 review covers a professional-grade countertop hydrogen water generator designed to produce hydrogen-rich water continuously and on demand. The Zontos Z3 uses a flow-through PEM/SPE electrolysis system rather than preparing one sealed bottle at a time. This page includes independent Zontos Z3 test results, flow-rate measurements, serving-dose calculations, electrical performance, current configurations, and Zontos Z3 price information.
Independent H2HUBB testing measured an average dissolved-hydrogen concentration of approximately 2.65 mg/L across eight primary tests. The normal tested range was approximately 2.0–3.0 mg/L, with a later high measurement of approximately 3.2 mg/L. At an average measured flow rate of 1.08 L/min, the system delivered approximately 2.86 mg of dissolved molecular hydrogen per minute.
Zontos Z3 Review & Independent Test Results
Zontos Z3 Review & Test Results
The Zontos Z3 is a professional-grade countertop hydrogen water generator designed to dispense hydrogen-rich water continuously and on demand. Unlike a portable hydrogen bottle that prepares one sealed serving at a time, the Z3 uses a flow-through PEM/SPE electrolytic system and dispenses water at approximately the speed of a premium refrigerator water dispenser.
Independent H2HUBB testing using H2Blue® reagent measured an average dissolved-hydrogen concentration of approximately 2.65 mg/L across eight primary tests. The individual measurements ranged from approximately 2.0–3.0 mg/L.
The highest concentration measured during the primary test series was approximately 3.0 mg/L. A later follow-up measurement reached approximately 3.2 mg/L. H2HUBB emphasizes the 2.65 mg/L average as the more useful indicator of repeatable performance rather than presenting the highest result as the expected output from every glass.
The system produced an average water flow rate of approximately 1.08 L/min. At the measured 2.65 mg/L average concentration, that flow delivered approximately 2.86 mg of dissolved H₂ per minute.
The available H2HUBB report also found that the Z3 did not increase the pH of the test water. Based on its verified dissolved-hydrogen concentration, continuous output, flow rate, electrical performance, operation, and overall reliability during the evaluation period, the tested Zontos Z3 configuration received the H2HUBB Seal of Approval.
Approximate Hydrogen Dose per Serving
The Zontos Z3 is a continuous-flow system, so the total dissolved-hydrogen dose depends on the amount of water dispensed. Based on the independently measured 2.65 mg/L average:
- 8 oz Serving: Approximately 0.63 mg of dissolved H₂
- 12 oz Serving: Approximately 0.94 mg of dissolved H₂
- 16 oz Serving: Approximately 1.25 mg of dissolved H₂
- 20 oz Serving: Approximately 1.57 mg of dissolved H₂
- 24 oz Serving: Approximately 1.88 mg of dissolved H₂
- 32 oz Serving: Approximately 2.51 mg of dissolved H₂
- One Minute of Continuous Flow: Approximately 2.86 mg of dissolved H₂ in approximately 1.08 L
These serving estimates use the independently measured average concentration. Actual dose can vary with water temperature, source-water chemistry, internal cell condition, flow rate, maintenance, and the time between dispensing and consumption.
Independent Zontos Z3 Test Procedure
The Zontos Z3 was tested using highly filtered source water measuring approximately pH 8 and 250 TDS. Water temperature during testing was approximately 61–66°F.
H2HUBB performed eight primary H2Blue concentration measurements. The readings were approximately 2.0, 2.2, 2.6, 2.7, 3.0, 2.9, 2.9, and 2.9 mg/L, resulting in an average of approximately 2.65 mg/L.
Flow testing produced measurements of approximately 1.08, 1.08, and 1.10 L/min, with a reported average of approximately 1.08 L/min.
Electrical and Dissolution Performance
The Z3 power supply was rated at 24 V, 5 A, and 120 W. H2HUBB measured approximately 6.8 V, 8.0 A, and 54.4 W at the electrolytic cell.
Using the documented electrical-performance calculation, the system had an estimated theoretical maximum of approximately 4.51 mg/L. The documented 3.0 mg/L result represented an estimated dissolved-hydrogen efficiency of approximately 66.5%.
Bottle-Top and In-Line Configurations
Zontos currently markets two Z3 configurations. The Z3-BT bottle-top system uses an eight-cup reservoir and does not require permanent plumbing. It requires a suitable water source and an electrical outlet.
The Z3-IL in-line system connects directly to a suitable water source. It includes water-level indicators and is designed for a more permanent installation.
The uploaded H2HUBB report documents a counter-top Z3 unit tested in 2019. Buyers should confirm with H2HUBB which current Z3 configuration is being quoted and whether any hardware or specification changes have occurred since the tested unit was produced.
Report Scope Clarification
The available Zontos Z3 test report documents dissolved-hydrogen concentration, water flow, source-water pH, electrical performance, operation, and short-term reliability. It does not include separate chlorine or ozone testing results. The page should therefore not claim that H2HUBB independently verified chlorine or ozone performance for this unit.
