Specification comparison
HERO Bath vs. AlkaWay Hydrogen Bath and Inhaler
Quick answer
HERO Bath is a purpose-built bath system rated at 3.75 L/min. AlkaWay's Hydrogen Bath and Inhaler is a dual-purpose device whose only published flow-rate specification — 300 ml/min — is stated for its inhalation mode; no separate, higher output figure is published for bath use. Based on AlkaWay's own specifications, HERO Bath's dedicated output is roughly 12.5x higher.
| Specification | HERO Bath | AlkaWay Hydrogen Bath and Inhaler |
|---|---|---|
| Published flow rate | 3.75 L/min (3,750 ml/min) | Up to 300 ml/min (stated for inhalation mode) |
| Bath-specific flow rate published | Yes — dedicated bath spec | Not published separately from inhaler mode |
| Design | Purpose-built for bath-volume water | Dual-purpose inhaler adapted for bath use |
| Hydrogen concentration | Above 2,000 ppb | Not published |
| Purity verification | Independent third-party lab (QTT) | Not published |
When comparing hydrogen bath systems, the flow rate matters more than the marketing category. A bath holds far more water than a glass or a nasal cannula delivers in a session — the rate at which hydrogen gas is actually produced and infused determines whether a bath reaches meaningful dissolved hydrogen concentration in a practical timeframe, not just whether a product is labeled "nano-bubble."
AlkaWay markets its Hydrogen Bath and Inhaler for both inhalation and bathing. The only flow-rate specification published on their own product page is 300 ml/min, stated for pure hydrogen inhalation — no separate, higher-output figure is published for bath mode. This is consistent with a dual-purpose design: one electrolysis cell, sized for inhaler-scale output, adapted to also serve a full bath.
HERO Bath is engineered specifically for bath use, rated at 3.75 L/min — publicly verified, independently lab-tested, and specific to bathing rather than shared with an inhalation function. Based on AlkaWay's own published specification, that's roughly 12.5 times the flow rate for the same purpose.
This isn't a claim about whether AlkaWay's product works — it's a comparison of what's actually published. We build the equipment; you can check the numbers yourself.
