Key similarities
- Same SPE/PEM hydrogen-separation technology at 99.99% purity
- Same certification stack and 12-month warranty
- Same accessory ecosystem — cannulas, Y connectors, humidifier tubes
Key differences
- Output: 1800 vs 3000 ml/min total (1200 vs 2000 ml/min pure H₂)
- Outlets: two-user vs true multi-user delivery
- Footprint: same 260 × 340 × 420 mm case in both — QY-A3000 is 2 kg heavier for the higher-output stack
- Intended use: home/studio vs clinic/spa/retreat
Which one fits you?
Sessions are mostly solo or two-user, you want the highest single-user output in the QY-A series, and you're operating from a home or small studio.
Three or more people will share sessions, you run a clinic, spa or wellness retreat, or you need a platform built for continuous multi-user duty cycles.
Both machines carry CE, FCC, RoHS and are made in ISO 9001 / ISO 13485-aligned facilities. Certifications describe hardware and manufacturing, not therapeutic status.
View all certifications →Both use the same cell-rinse cadence and accessory consumables. The QY-A3000's higher duty cycle means more frequent cannula and humidifier replacement and an annual cell inspection is recommended for commercial operators.
Frequently asked questions
- Is the QY-A3000 a clinical machine?
- It is engineered for multi-user, high-utilisation settings — clinics, spas, wellness retreats. It is not registered as a medical device; Hydrogen Machines products are general wellness devices.
- Can the QY-A3000 be used at home?
- Yes — and many serious home users do — but it's overspecified for solo or two-user households. The QY-A1800 is usually the more economical choice for a home.
- How many people can use a QY-A3000 at once?
- Multiple users in parallel via the multi-outlet manifold. For exact concurrent-session counts, see the product page and the buyer's guide.
