The H-2000 is an inhalation device designed for the delivery of molecular hydrogen (H₂) gas. During the session, hydrogen gas generated by the device is inhaled through a mask or nasal cannula. This approach is based on hydrogen inhalation methods that have been explored in scientific research in different countries.

Molecular hydrogen is a small gaseous molecule that has been the subject of various scientific studies investigating its potential biological interactions. Such applications may be considered among supportive approaches within certain longevity and lifestyle programs.

The H-2000 device features a compact and portable design. The duration of sessions, frequency of use, and program planning are determined by healthcare professionals following an individual assessment.
