Description :
This H2Rich HM-500 review covers a high-output HM-500 hydrogen inhaler manufactured by HydrogenMed Biotechnology Corp. This 500 mL/min hydrogen inhaler was independently tested by H2HUBB for hydrogen flow, long-term reliability, operating controls, and safety. The page also includes specifications, inhaled-H₂ estimates, maintenance guidance, pricing, and the current HM-500 discount.
Independent H2HUBB testing measured an initial average molecular-hydrogen output of approximately 557.6 mL/min at SATP. The device remained within approximately 0.5–1.5% of its original output during six-month and one-year evaluations, confirming stable long-term hydrogen production.
H2Rich HM-500 Review & Independent Test Results
H2Rich HM-500 Review & Test Results
The H2Rich HM-500 is a household and professional-use pure-hydrogen inhalation system manufactured by HydrogenMed Biotechnology Corp. The system uses PEM/SPE membrane electrolysis and a dedicated hydrogen outlet to deliver molecular hydrogen through a single-user nasal cannula.
Independent H2HUBB testing measured an initial average hydrogen output of approximately 557.6 mL/min at SATP, equivalent to approximately 46.0 mg of molecular hydrogen per minute. This exceeded and confirmed the manufacturer-rated output of 500 mL/min.
Ten initial flow measurements ranged from approximately 544–568 mL/min, demonstrating consistent production during repeated testing. The device’s report-stated theoretical maximum was approximately 559.38 mL/min under the evaluated electrical conditions.
HM-500 Hydrogen Inhaler Performance
Using the current H2HUBB inhaled-H₂ concentration model, the verified 557.6 mL/min flow corresponds to approximately 2.48–2.86% estimated inhaled hydrogen for one adult at a resting minute ventilation of 6.5–7.5 L/min.
VE, or minute ventilation, is the total volume of air a person breathes each minute. H2HUBB’s model applies approximately 20 seconds of active inhalation during every minute of nasal-cannula use, resulting in approximately 185.87 mL of effective inhalation-phase hydrogen per minute.
Actual inhaled concentration varies with minute ventilation, breathing pattern, cannula placement, mouth breathing, tubing resistance, accumulated moisture, and gas leakage.
500 mL/min Hydrogen Inhaler Test Results
H2HUBB began testing the evaluated HM-500, serial number HM-1720E005, in September 2019. The evaluation included the initial flow analysis followed by approximately three-month, six-month, and one-year reliability reviews.
- Initial Average: Approximately 557.6 mL/min
- Three-Month Result: Approximately 549 mL/min
- Six-Month Stability: Within approximately 0.5–1.5% of the initial result
- One-Year Stability: Within approximately 0.5–1.5% of the initial result
These results demonstrate that the HM-500 hydrogen inhaler maintained stable hydrogen production throughout the long-term evaluation. The report identified few observable performance issues over the one-year testing period.
Long-Term Reliability and Water-Collector Maintenance
During the six-month and one-year evaluations, H2HUBB observed a temporary loss of gas delivery when the external water collector became heavily filled. The condition resembled an air lock and occurred when the collector reached approximately 75–85% capacity.
Normal hydrogen delivery returned after the device was turned off and the accumulated water was drained from the collector. This was the only recurring operational condition noted during the long-term evaluation and appears preventable through routine maintenance.
Users should inspect and drain the water collector regularly rather than allowing it to become mostly full. Tubing and cannulas should also be checked for moisture accumulation or obstruction before each session.
PEM/SPE System and Purity Disclosure
The evaluated HM-500 used PEM/SPE membrane electrolysis with a power-supply rating of approximately 5 V, 50 A, and 250 W. The report calculated a theoretical maximum hydrogen output of approximately 559.38 mL/min under the evaluated conditions.
HydrogenMed and its referenced third-party laboratory documentation state that the system produces hydrogen purity of 99.999% or greater. H2HUBB independently measured hydrogen output and evaluated system operation but did not perform the gas-purity analysis within this report.
The system uses distilled water and includes an internal reservoir-filter cartridge. HydrogenMed states that the filter helps maintain reservoir-water quality and hydrogen purity.
H2HUBB Safety and Operational Assessment
The HM-500 provides a simple control interface with power, filter-reset, filter-replacement, gas-blockage, and water-alert functions. The system also includes a hydrogen observation window, drain valve, internal reservoir filter, and external water collector.
HydrogenMed currently lists automatic protection for blocked gas flow, low water, excessive reservoir water, machine tilting, and extended operation. The evaluated configuration automatically stopped after approximately two hours of continuous operation.
A newer H2Rich store listing describes 24-hour operation. Because this differs from the original manufacturer page and the configuration evaluated by H2HUBB, buyers should confirm the current machine’s firmware, timer behavior, and operating instructions before purchase.
Based on its independently verified hydrogen output, one-year flow stability, evaluated safety functions, and overall reliability, the H2Rich HM-500 received the H2HUBB Seal of Approval.
Keep the nasal cannula, tubing, hydrogen outlet, generated hydrogen, and all related accessories away from flames, sparks, smoking materials, static discharge, heating elements, and every other ignition source.
