Model Comparison
HYD-1500 vs HYD-1800 vs HYD-3000: Full Model Comparison
Quick answer: All three Revive Hydrogen generators use the same PEM (proton exchange membrane) electrolysis system and produce hydrogen at the same 99.992% purity. They differ in maximum flow rate and rated power. The HYD-1500 delivers up to 1,500 mL/min at 375W ($3,599, regularly $3,999). The HYD-1800 delivers up to 1,800 mL/min at 450W ($3,869, regularly $4,299). The HYD-3000 delivers up to 3,000 mL/min at 750W ($4,499, regularly $4,999). Choose based on session length, whether two people will use it, and whether it is for home or clinic use.

Which model should you choose?
Who is the HYD-1500 for?
The HYD-1500 suits a single user running one or more daily sessions at home. At 375W it draws the least power of the three and runs on a standard household circuit without concern. Its 900 mL/min low setting is well matched to longer, relaxed sessions. Choose it if one person will use the machine and cost matters more than maximum output.
Who is the HYD-1800 for?
The HYD-1800 is the middle option: 20% more maximum output than the HYD-1500 for $300 more. It makes the most sense for a household where two people share the machine using the included Y-connector, since splitting the flow between two cannulas divides the output each person receives. Choose it if you want headroom without stepping up to clinic-grade power draw.
Who is the HYD-3000 for?
The HYD-3000 is the clinic and multi-user model. At 2,000 mL/min of hydrogen output it can run two users at 1,000 mL/min each through the Y-connector, which is why wellness clinics, recovery studios, and medspas typically specify it. Its 1,500 mL/min low setting matches the HYD-1500’s maximum, so it also works as a single-user machine with substantial headroom. It draws 750W, so plan the circuit accordingly.
What is identical across all three models?
More is shared than differs. All three models use the same PEM electrolysis stack, produce hydrogen at the same lab-verified 99.992% purity, weigh the same, run on the same distilled water requirement, use the same 6-liter water tank with integrated UV-C treatment, and ship with the same accessory set:
- 4x nasal cannula
- Y-type connector and connecting tubes
- 2x humidifier cups
- Goggles with ear tubes for localized application
- Drain tube, power cord, and printed manual
All three also support the same three operating configurations: pure hydrogen output, dual-user hydrogen via the Y-connector, and oxyhydrogen (Brown’s gas) output.
Frequently asked questions
Is a higher flow rate always better?
Not necessarily. Higher flow rates shorten the time needed to reach a given hydrogen exposure, and they allow two people to use the machine at once without either dropping to a low output. For a single user with time for a 30–60 minute session, the HYD-1500 provides ample output. Flow rate matters most when session time is limited or when the machine is shared.
Do the models differ in hydrogen purity?
No. All three models produce hydrogen at 99.992% purity, verified by independent lab testing. Purity is a function of the PEM membrane and gas separation system, which is identical across the range. Only flow rate and rated power differ.
Can two people use one machine at the same time?
Yes. Every model ships with a Y-type connector that splits output between two nasal cannulas. The total output is divided between the two users, so a HYD-3000 producing 2,000 mL/min of hydrogen delivers roughly 1,000 mL/min per person. This is the main reason clinics choose the higher-output model.
What kind of water do these generators require?
Distilled water with a TDS (total dissolved solids) reading of 5 or below. Tap water and mineral water contain dissolved solids that damage the PEM membrane and shorten the life of the electrolyzer. Hydrogen dissolving rods are not recommended with these machines because of back pressure risk.
How long is the warranty?
All three models carry a 3-year warranty. Warranty service is handled remotely first, through guided self-repair, parts shipment, and video support calls, which resolves most issues without shipping the unit.
