Three Important Facts for G5 Owners
- Batteries Remain Available: G5 batteries are still in production and work with both the G5 and Rove 6. AC/DC power supplies and column pairs are also cross-compatible.
- Repair Parts Are Limited: Internal components like sieve beds and particle filters are only available while supplies last. We recommend budgeting for a Rove 6 upgrade if your G5 is older or needs frequent service.
- Beware of Counterfeits: If you see a "new" G5 being sold by a non-certified seller, be cautious. It may be old stock or a dangerous counterfeit. Always buy from authorized dealers.

Frequently Asked Questions
Is the Inogen One G5 still available for purchase?
No. The Inogen One G5 was officially discontinued by the manufacturer on March 31, 2025. The Inogen Rove 6 is the direct replacement and current flagship model.
Are G5 batteries compatible with the Inogen Rove 6?
Yes. All G5 batteries, AC/DC power supplies, and column pairs are fully compatible with the Inogen Rove 6. This makes upgrading easy since your existing accessories carry over.
Can I still get my Inogen G5 repaired?
Yes, for now. Main Clinic Supply is an Authorized Inogen Service Center and continues to provide certified repairs and diagnostics. However, internal repair parts like sieve beds and particle filters are only available while manufacturer stock lasts. G5 batteries remain in production with no discontinuation planned.
How long will G5 repair parts be available?
There is no set date, but once Inogen's existing stock of sieve beds and particle filters is depleted, they will not be replenished. G5 batteries, however, are still being manufactured and will remain available for the foreseeable future.
Should I buy a used G5 or a new Rove 6?
For most buyers, a new Rove 6 is the better choice. It comes with a full warranty, quieter operation, and improved performance. A used G5 may have worn sieve beds or unknown service history.
How do I know if a G5 for sale is legitimate?
Only purchase from authorized Inogen dealers. If you see a "new" G5 being sold anywhere, be cautious as it may be old stock, refurbished, or counterfeit. Main Clinic Supply only sells genuine, authorized products.
