This VEVOR hydrogen inhalation machine produces up to 99.99% high-purity hydrogen using electrolysis with purified/distilled water (TDS ≤ 5). It features a dual-port design for 1–2 users and offers three output modes (H2, O2, and H2+O2) with a combined output of 180 ml/min. A built-in timer provides 30/60/90-minute sessions with a clear status indicator for easy operation. For safety, it automatically stops if tilted at 45°, and it runs quietly for comfortable use. Its compact body and built-in 10,000 mAh rechargeable battery make it suitable for home or travel.
