Inogen One G5 Portable Oxygen Concentrator – Reliable, Lightweight, and Life-Changing Freedom

This Inogen One G5 portable oxygen concentrator belonged to my late father, who had COPD. It was truly a game changer for him — giving him the freedom and confidence to leave the house, visit friends, and enjoy small adventures without worry.

The G5 is lightweight, quiet, and dependable, designed to make everyday life easier for anyone needing oxygen therapy on the go. Whether used at home, in the car, or out and about, it provides steady, pulse-delivered oxygen in a compact and travel-friendly form.

Key Features

• Compact & Lightweight: Weighs only around 2.2 kg with battery — easy for most people to carry or hang from a wheelchair.
• Quiet operation: Discreet and comfortable in public settings.
• Pulse Dose Technology: Delivers oxygen only when you inhale — my father found this worked better for him than the continuous flow machine he had at home.
• Flow Settings 1–6: Adjustable to suit different oxygen needs.
• Up to 9 hours battery life (with extended battery).
• Clear LCD screen showing flow level, alerts, and battery status.
• FAA-approved for air travel – great for longer trips.

From Our Family’s Experience

This machine gave my Dad the independence to get out and enjoy life again. Its lightweight design made it easy for him to carry, and the quiet operation meant he could move about confidently without drawing unwanted attention. I hope it can offer the same sense of freedom and reassurance to someone else who needs it.
