Which system should you specify?
Choose H6 Pro™
The right specification for most home and single-practitioner setups. 6,000 ml/min covers daily personal sessions with headroom for up to three users, at the lowest entry price in the range.
Buy H6 Pro™ — $10,647Choose H8 Pro™
Specify the H8 Pro when sessions run back to back. The higher 8,000 ml/min rating and twin control panels reach an equivalent hydrogen dose roughly 30% faster, which raises daily throughput in shared spaces.
Buy H8 Pro™ — $13,797Choose Bath One™
A different delivery method rather than a different grade. Bath One™ infuses hydrogen into bath water for whole-body immersion, and is commonly installed alongside an inhalation machine in spa and residential wellness suites.
Buy Bath One™ — $4,295SPE/PEM generation vs tablets and reactive-metal systems
Membrane electrolysis (all Hydrogen Wellness systems)
- Purified water split across a solid polymer electrolyte membrane.
- Hydrogen separated from oxygen; 99.99% purity at generation.
- Measured, adjustable flow rate in ml/min with timed sessions.
- No consumable chemistry and no reaction residue.
Tablet and reactive-metal generation
- Hydrogen released by a chemical reaction with magnesium or similar metals.
- Reaction by-products and residue remain in the water.
- Output cannot be expressed as a controlled, continuous flow rate.

Comparison FAQ
- What is the difference between the H6 Pro and the H8 Pro?
- Both use the same SPE/PEM membrane platform, certifications, 10,000-hour rated stack service life and 12-month warranty. The H6 Pro is rated at 6,000 ml/min total gas output; the H8 Pro is rated at 8,000 ml/min and adds twin control panels, so it reaches an equivalent hydrogen dose roughly 30% faster and handles higher throughput in shared environments.
- Should I choose an inhalation machine or a hydrogen bath system?
- Inhalation machines (H6 Pro, H8 Pro) deliver hydrogen gas through a nasal cannula in timed sessions. Bath One™ dissolves hydrogen into bath water for whole-body immersion. They are different delivery methods rather than different grades of equipment, and many buyers operate both in the same space.
- Do all three systems ship with the same warranty and service life?
- Yes. Every system carries a 12-month warranty and a 10,000-hour rated PEM stack service life, which is approximately ten years at typical daily use.
- Is shipping and duty included in the listed price?
- Yes. All listed prices are DDP (Delivered Duty Paid) worldwide, so import duties and taxes are included and there are no charges on delivery.
- How does SPE/PEM generation differ from tablets and reactive-metal generators?
- SPE/PEM electrolysis splits purified water across a solid polymer membrane and separates hydrogen from oxygen, producing 99.99% purity with no consumable chemistry. Tablets and reactive-metal systems rely on a chemical reaction with magnesium or similar metals, which introduces reaction by-products and residue and cannot be measured or adjusted as a continuous flow rate.
