Life Source Oxygen Concentrator 5L

Lifesource Oxygen Concentrator LS-7F-5B with Nebulizer & Purity Meter

The Lifesource LS-7F-5B Oxygen Concentrator is designed for safe and reliable home oxygen therapy. It electronically separates oxygen from room air and delivers high-purity oxygen directly to the user through a nasal cannula. Clinical studies confirm oxygen concentrators are therapeutically equivalent to other oxygen delivery systems.
