What’s in this kit — part by part
Five genuine Inogen One G5 parts that keep your concentrator clean and running through the year, plus one optional tool you add only if you’ll service it yourself. Each one, what it does, and how often to change it.
Replacement column pair (sieve beds)
The heart of oxygen production in your G5 — restores oxygen purity and efficiency when output drops or the device signals a column alert.
Intake filter assembly (×3)
Keeps ambient dust and debris out at the air entry and preserves clean airflow into your G5. Three included — about one every four months.
Particle filter (pair)
Captures airborne particles in daily use and protects the internal airflow path. Inspect regularly and replace when worn.
Output filters (10-pack)
Final, clean filtration before the oxygen reaches your cannula — a full year’s supply.
Cannula barb (+ spare)
Secure nozzle that keeps your cannula connection sealed and leak-free, from the concentrator to your tubing. A spare is included.
Output filter removal tool
Safely removes the barb so you can access and swap the output filter beneath it. Optional add-on for at-home service.
Quantities are tailored for a full year of standard use — including three intake filters, about one every four months, and a 10-pack of output filters. Heavy users or travelers may want extra RP-410 output filters.
Your G5 maintenance calendar
A simple at-home routine keeps oxygen delivery consistent and prevents surprise downtime. Here’s what to do — and when.
Tip: set calendar reminders — the 1st of each month (RP-410), every four months (SP-804) and once a year (RP-502).
Made for the Inogen One G5 only — not the G3, G4 or Rove 6, which use their own model-specific kits.
How to change the output filter & barb
A quick job you can do at home with an output-filter tool (RP-404) — add it to your kit above if you need one.
- Power off the G5 and disconnect it from power.
- Use an output-filter tool (RP-404) to gently remove the barb.
- Pull the old RP-410 output filter straight out and discard it.
- Insert a new RP-410, seated fully and flush.
- Reinstall the barb securely and check for a snug fit.
- Power on, then confirm normal airflow with no leaks.
Planned upkeep like this protects oxygen purity, prevents surprise interruptions and is simple enough for a caregiver to handle — everything in one kit instead of chasing parts one at a time.
