In The Box 📦
  • 2 x Inogen One G4 Replacement Columns (Sealed in protective packaging)
  • Visual Setup Instructions
  • (Note: This is a pair of internal parts only; the G4 machine and batteries are not included).

Setup & Use 📘

Turn off the G4 and remove the battery. Locate the latch button on the side of the column assembly. Push the latch and pull the old columns away from the device. Immediately remove the dust caps from the new columns and slide them into the machine until they click securely. Reattach the battery and plug the unit into AC power. The device will automatically reset the internal "Change Column" alarm.

Clinical-Grade Oxygen Production Renewed

Ensure your therapy stays effective and your machine stays out of the repair shop. These replacement columns are the heartbeat of the Inogen One G4, containing the molecular sieve material that converts room air into life-sustaining oxygen. By replacing these beds as soon as your machine prompts you, you prevent the risk of lower blood oxygen saturation and ensure that your ultra-portable concentrator remains a dependable source of medical-grade air for every journey.

High-Purity Zeolite Filtration

The G4 columns utilize advanced medical-grade Zeolite to effectively absorb nitrogen. As columns age, they lose their capacity to separate gases; installing a fresh pair instantly brings your oxygen concentration back up to 93% ± 3%. This restored purity is vital for proper respiratory support, ensuring that even on your highest setting, you receive the full therapeutic benefit prescribed by your doctor.

Instant User-Accessible Repair

Inogen revolutionized CPAP and Oxygen therapy by making these core components user-serviceable. You don't need tools, specialized technical skills, or the expensive downtime of shipping your unit to a service center. By simply pressing two buttons, the old columns slide out and the new ones click into place, allowing you to return to your daily activities in under a minute.

Automatic Logic Reset

When the "O2 Service Required" alert appears on your G4 display, the machine is sensing reduced sieve efficiency. These official columns feature built-in hardware that communicates with your device. Once installed, the Inogen G4 automatically recognizes the fresh filtration material and clears the service error, ensuring your data logs are accurate and your maintenance schedule stays on track.
