Should I just buy the QY-A3000 for home in case I need it later?

Usually no. The QY-A1200 already delivers the core hydrogen output most home users want. The QY-A3000's price, footprint and power draw only pay back if you genuinely need multi-user parallel sessions.

Can I run two people on a QY-A1200?

Yes — with the optional Y connector. Output is shared between the two cannulas. For three or more concurrent users, you want the QY-A3000.

Is the QY-A3000 a medical device?

No. Hydrogen Machines products are general wellness devices. The QY-A3000 is engineered for commercial duty cycles, not medical registration.

Which one has a better warranty?

Same 12-month warranty on both. Commercial operators of the QY-A3000 should plan an annual cell inspection regardless.

Internal product comparison

QY-A1200 vs QY-A3000

The core single-user home inhaler against the flagship multi-user platform.

Quick verdict

The QY-A1200 is the core home inhaler in the QY-A series — 1200 ml/min total flow at 99.99% purity in a compact, bench-top chassis. It's the most-recommended choice for serious solo home users and households of one to two people.
The QY-A3000 is the flagship multi-user platform — 3000 ml/min total flow with multi-outlet delivery for parallel sessions, designed for clinics, spas, wellness retreats and dedicated practitioners. It is meaningfully larger, heavier and more expensive, and it is overspecified for a single home user.
If you're choosing between these two for a home, the QY-A1200 is the answer in almost every case. The QY-A3000 makes sense when three or more users will share sessions, when sessions run back-to-back across a working day, or when the unit needs to support a paying clientele.

Buying advice

Which one fits you?

QY-A1200 is for you if…

You're buying for home, sessions are mostly solo (occasionally two-up with a Y connector), and you want the most-recommended core inhaler in the range without paying for clinical capacity you'll never use.

QY-A3000 is for you if…

Three or more people will share sessions, you run a clinic, spa or retreat, you need parallel delivery, or you want the highest-output single platform Hydrogen Machines offers.

Maintenance considerations

Both share the same cell-rinse cadence and consumables. The QY-A3000's commercial duty cycle means more frequent cannula and humidifier replacement; annual cell inspection is recommended for any operator running paying sessions.
