High output vs low output
Hydrogen output (ml/min) is the most-quoted spec, but it's only meaningful in context. Here's when more output helps, and when it doesn't.

Specifications at a glance
| High output (≥1500 ml/min) | Low to mid output (≤1200 ml/min) | |
|---|---|---|
| Typical total gas | 1500 – 3000+ ml/min | 300 – 1200 ml/min |
| Typical pure H₂ | 1000 – 2000 ml/min | 200 – 800 ml/min |
| Best session length | Shorter, more concentrated | Longer, lower-intensity |
| Best users per session | Two or more (Y connector or manifold) | Solo |
| Noise envelope | Higher (more cell duty) | Lower (smaller cell, less heat) |
| Footprint | Larger chassis / floor-standing | Compact bench unit |
| Power draw | Higher | Lower |
| Price band | Premium | Entry to mid |
| Best fit | Clinics, retreats, multi-user homes | Solo home users, bedrooms, long sessions |

Key similarities
- Both can use the same SPE/PEM cell technology and accessory ecosystem
- Both deliver high-purity hydrogen (see model documentation) when properly certified
- Both require clean feedwater and routine cell-rinse cycles
- Output alone doesn't determine therapeutic value — that's not a claim we make either way
Key differences
- Throughput: high-output machines deliver more hydrogen per minute
- Comfort envelope: low-output machines are usually quieter and lighter
- Use case: high-output suits multi-user and clinical settings; low-output suits long solo sessions
- Price and running cost: higher output usually means more capital and more power
Which one fits you?
You'll share sessions with two or more people, you operate a clinic or spa, you want shorter sessions, or you want the headroom to extend protocols later.
You're a single user, you value quiet operation, you want a compact unit, and you'd rather run longer sessions at a comfortable flow rate.
HERO Equipment and Documentation
Compare published specifications side by side.
- Model-specific laboratory documentation is available on the individual product pages.
- Compare the exact model's published electrolysis design and duty rating.
- Ask for certification documents for the exact model before purchasing.
- Direct pricing, 24-month machine warranty and tracked delivery under destination-specific shipping terms.
- Support handled directly by our own team — never through a distributor loop.
- A complete range: bathing, inhalation and hydrogen water, so the machine matches the routine.
Certifications and engineering claims describe hardware and manufacturing, not medical or therapeutic status.
Output rating is independent of certifications. CE, FCC, RoHS and ISO-aligned manufacturing apply across both classes. Always check that the published output is supported by certified electrical and EMC compliance.
View all certifications →Higher-output cells run hotter and have a higher duty cycle, which can mean more frequent cell rinses, faster cannula wear and a more attentive feedwater regime. Lower-output cells are typically lower-maintenance.

Report LH2025050017 covers HERO Inhaler 900, 1200, 1500, 2000 and Pro 3000. Check the measured outlet and test conditions; do not extend results to other models or untested flow rates.
Certifications, purity figures and engineering specifications describe hardware and manufacturing quality. Products are sold as general wellness devices, not FDA-approved — not medical devices, not TGA registered, and not intended to diagnose, treat, cure or prevent any disease.

Frequently asked questions
- Is more ml/min always better?
- No. More ml/min means more hydrogen per minute — useful when sessions are short, shared or high-utilisation. For long solo sessions in a quiet room, lower output is often more comfortable.
- How do I compare ml/min figures between brands?
- Use total gas (H₂ + O₂) like-for-like, then separate the pure H₂ stream. Some brands quote only total flow; others quote only pure H₂. Always check which one a given figure refers to.
- Does higher output mean higher hydrogen concentration in the blood?
- We don't make therapeutic claims either way. Higher delivered ppm in the breathing stream is one input among many in research; the rest depends on protocol and the user.
