Frequently Asked Questions

Molecular hydrogen (H₂) inhalation is a modern, non-invasive wellness practice. Our devices generate pure hydrogen gas, which you inhale through a comfortable nasal cannula. It's quiet, simple, and designed to fit into your daily routine.

Across published human studies, molecular hydrogen has generally been reported as well tolerated. Safety conclusions remain specific to the study population, concentration, delivery method and protocol investigated. Hydration-H₂ systems must always be used according to the operating and safety instructions.

A typical inhalation session lasts between 30 and 60 minutes. Many users incorporate it into their morning routine, during reading or work, or as an evening wind-down. Our devices include a built-in timer for convenience.

Absolutely. The devices are designed to be ultra-quiet. You can read, work, meditate, watch TV, or simply relax during your session. The nasal cannula is lightweight and comfortable.

Our devices are generally suitable for adults. For children or adolescents, use should only take place after consulting a doctor.

Several times a week or even daily, depending on your needs — particularly if the focus is on recovery or well-being.

Individual experiences vary. Effects are not guaranteed and depend on factors including the individual, session regularity and other circumstances.

Yes, it’s ideal as a complement to exercise, wellness, or other restorative activities.

Consistency is key — many start with several sessions a week.

It’s flexible: in the morning for focus and energy, or in the evening for relaxation and recovery.

The two work differently in the body, and that’s really the interesting part. Inhaled H₂ moves from the lungs into the bloodstream within seconds, reaching tissues, muscles and the brain quickly — supporting the whole body at once. Hydrogen water takes a different route: it passes through the digestive system first. In human studies, drinking hydrogen-rich water for 8 weeks to 2 months has been shown to shift gut bacteria toward more beneficial, butyrate-producing strains — linked to a healthier gut lining and lower inflammation. Hydration-H₂ doesn’t make you choose one or the other. The H₂ Water-Dissolving Rod comes included with the S 900 Plus, so you can inhale for fast, whole-body support and drink hydrogen water for gut-focused support, both from the same system. For the S 3000 Pro, the rod is available as an accessory, so spas and clinics can offer both formats too.

The Hydration S 900 Plus has a total flow rate of 900 ml/min (H₂ 600 ml/min + O₂ 300 ml/min) and is our compact home device designed for personal use. The Hydration S 3000 Pro has a total flow rate of 3,000 ml/min (H₂ 2,000 ml/min + O₂ 1,000 ml/min) and is our professional-grade device with dual-user capability, built for wellness centres, spas, and clinics. Both systems generate molecular hydrogen at 99.99% purity.

We recommend using distilled or purified water for optimal device performance and longevity. The Hydration S 900 Plus has a built-in reservoir, while the Hydration S 3000 Pro also features a built-in reservoir.

Maintenance is minimal. Regular tasks include refilling the water reservoir, occasional cleaning of the cannula, and periodic replacement of consumable parts as described in the user manual. Our support team is always available to help.
