HBS10 Hydrogen Inhaler Review, Test Results & Discount
Product Review & Independent Test Results
Review the product overview, H2HUBB testing information, measured performance when available, pricing, specifications, and buying guidance.
This HBS10 review covers a compact household oxyhydrogen inhalation device manufactured by Hydrogen Technologies Bulgaria. The HBS10 hydrogen inhaler produces a measured blend of approximately two parts molecular hydrogen to one part oxygen and can also direct gas through a hydrogen-water accessory. This page includes independent H2HUBB test results, inhaled-H₂ estimates, specifications, potassium-hydroxide safety guidance, pricing, and the current HBS10 discount.
Independent H2HUBB gas-displacement testing measured approximately 297 mL/min of molecular hydrogen and approximately 445 mL/min of total oxyhydrogen gas at SATP. These results closely confirmed the manufacturer’s stated performance of approximately 300 mL/min H₂ and 450 mL/min total gas.
HBS10 Review & Independent Oxyhydrogen Test Results
HBS10 Hydrogen Inhaler Review & Test Results
The HBS10 hydrogen inhaler is a compact household oxyhydrogen inhalation device manufactured by Hydrogen Technologies Bulgaria. Unlike a PEM pure-hydrogen system, the HBS10 uses non-membrane alkaline electrolysis to produce a combined gas containing approximately two parts molecular hydrogen and one part oxygen.
Independent H2HUBB gas-displacement testing measured approximately 297 mL/min of molecular hydrogen, equivalent to approximately 24.5 mg/min of H₂. Total oxyhydrogen production measured approximately 445 mL/min at SATP.
These results closely confirmed the manufacturer’s stated performance of approximately 300 mL/min of hydrogen and 450 mL/min of total H₂/O₂ gas. The measured mixture contained approximately 66.7% hydrogen by volume, consistent with the expected two-to-one hydrogen-to-oxygen ratio produced by water electrolysis.
Using the current H2HUBB inhaled-H₂ concentration model, approximately 297 mL/min of verified hydrogen output corresponds to approximately 1.32–1.52% estimated inhaled H₂ at an adult resting minute ventilation of 6.5–7.5 L/min. VE, or minute ventilation, is the total volume of air breathed per minute.
The estimate applies approximately 20 seconds of active inhalation during each minute of nasal-cannula use, producing an effective inhalation-phase hydrogen delivery of approximately 99 mL/min. Actual concentration varies with breathing pattern, minute ventilation, cannula fit, mouth breathing, tubing resistance, and gas leakage.
Oxyhydrogen and Brown’s Gas Inhaler Design
The HBS10 is also described as a Brown’s gas inhaler or HHO inhalation device. Hydrogen and oxygen are generated together within the non-membrane electrolytic cell rather than separated by a PEM membrane.
H2HUBB recommends describing the device publicly as an oxyhydrogen system rather than a pure-hydrogen inhaler. The approximately 297 mL/min test result represents the hydrogen component of the measured 445 mL/min combined-gas output.
H2HUBB Safety and Operational Assessment
H2HUBB identified low-water protection with a start-lock function, an electronic electrolyte-level indicator, a humidifier reservoir, backflow protection, internal cooling, heat management, and a stainless-steel enclosure.
The HBS10 exceeded H2HUBB’s minimum hydrogen-flow requirement and closely confirmed its manufacturer-rated output. Based on its measured inhalation performance and evaluated operating safeguards, it received the H2HUBB Seal of Approval.
Approval does not eliminate the hazards associated with potassium hydroxide, mixed hydrogen-and-oxygen gas, improper electrolyte preparation, insufficient humidifier maintenance, or exposure to an ignition source. Responsible operation and complete adherence to the current manual remain essential.
Hydrogen Water Attachment
The HBS10 includes an attachment for bubbling gas through water. However, the pitcher supplied with the evaluated unit leaked around the gas-input connection during the first day of testing. H2HUBB was therefore unable to complete a formal dissolved-hydrogen evaluation.
No specific dissolved-hydrogen concentration should be presented as independently verified by H2HUBB. The HBS10 recommendation and Seal of Approval apply primarily to the device’s inhalation performance.
Keep the cannula, tubing, device, and produced oxyhydrogen gas away from flames, sparks, smoking materials, static discharge, hot surfaces, and all other ignition sources.
