This VEVOR hydrogen inhalation machine generates up to 99.99% high-purity hydrogen via electrolysis using purified/distilled water (TDS ≤ 5). It features dual ports and three output modes (H2, O2, or H2+O2) for flexible use by one or two people. A built-in timer (1/2/3 hours) and real-time status indicators make operation simple. The compact, low-noise design and included carrying case make it suitable for home, office, travel, and wellness settings. It can also be used with a hydrogen dissolving rod to create hydrogen-rich water.
