Overview

Replacement columns are essential for keeping your Inogen One G4 portable oxygen concentrator in top shape. These replacement columns contain sieve beds that filter out nitrogen from the air to deliver high-purity oxygen, making them a crucial part of your device’s performance.


Over time, these sieve beds wear out, which is why regular replacement is key to maintaining consistent oxygen delivery. When your G4 displays the “replace columns” alert, it’s time to switch them out. Fortunately, replacing them is straightforward and doesn’t require any tools—just follow the step-by-step instructions. 

Guide and Resources

Important Tips

  • Replace the columns as soon as the “replace columns” alert appears to avoid interruptions in oxygen therapy.
  • Follow the step-by-step instructions carefully during replacement to ensure a secure fit and proper functioning.
  • Clean the exterior of the concentrator regularly to prevent dust buildup that could affect column performance.
  • Monitor your oxygen concentrator's performance after replacing the columns to ensure they are working correctly.
  • Avoid dropping or mishandling the columns, as this can damage the sieve beds and reduce their effectiveness.
  • Use a calendar reminder or set a phone alert to check the condition of your columns every 18-24 months, or as recommended by your device.
