Cleaning and Maintenance of the Inogen One G5

The Inogen One G5 is one of the most portable and powerful oxygen concentrators on the market. To keep it performing in peak condition, it’s essential to practice consistent cleaning and maintenance practices. Read on to learn how to clean and care for your Inogen One G5.

Weekly G5 Maintenance

Some components of the Inogen One G5 need to be cleaned weekly:

  • Concentrator Case: Keeping your Inogen One G5 clean and dust-free will help keep your machine working properly. To clean the outside of the concentrator case, dampen a cloth with water and a mild detergent, like Dawn. Repeat this process about once a week to avoid buildup of dust, dirt, or other household debris. Never submerge your Inogen G5 concentrator in water.
  • Particle Filters: Remove your device’s filters from the front and back of the machine. To clean the particle filters, use water and the same mild detergent as you used to clean the exterior of the machine. Then, rinse with water and dry them completely before reusing them. Cleaning these filters every week ensures your machine can consistently maintain airflow.

Regular G5 Replacements

Some of the Inogen One G5’s equipment requires regular replacements. These include:

  • Nasal Cannula: The nasal cannula of the Inogen One G5 should be replaced on a regular basis according to your health care provider’s recommendations. When ordering a replacement, keep in mind that a single lumen cannula should not exceed 25 feet in order to ensure proper breath detection and oxygen delivery.
  • Column Replacement: When it’s time to replace the machine’s columns, the Inogen One G5 will display a low priority message on your screen, sound a double beep, and show a red or yellow light. This indicates that column maintenance is required within the next 30 days.

Rare Replacements

When properly maintained, the Inogen G5 is built to last. However, some equipment, like fuses, may require a replacement at some point.

Fuse Replacement: The fuse is found in the Cigarette Lighter DC power plug. If you use the DC input cable with a good power source and the unit is not receiving power, the fuse may need to be replaced. To replace the fuse:

  1. Remove the tip by unscrewing the retainer.
  2. Remove the retainer, tip, and fuse. The spring should remain inside the Cigarette Lighter Adapter housing. If the spring is removed, make sure to replace the spring before inserting the replacement fuse.
  3. Install a replacement fuse (Inogen RP# 125 (BUSS MDA-12)) and reassemble the tip. Ensure the retainer rig is properly seated and tightened.
