When did the G5 discontinuation happen?
Inogen officially ended G5 production on March 31, 2025. New G5 units have not rolled off the manufacturing line since that date. Inogen's announcement positioned the Rove 6, which began shipping in 2024, as the direct successor.
The discontinuation was planned and pre-announced. Inogen wound down G5 production over several months in early 2025 while ramping up Rove 6 production, which means there is no surplus inventory of brand-new G5 units sitting on dealer shelves waiting to be sold at original launch pricing.
Why did Inogen end the G5 line?
The G5 launched in 2020. By 2024, the design was approaching end-of-life from a manufacturing economics standpoint. The Rove 6 carries forward what worked about the G5 (six pulse settings, lightweight chassis, accessory ecosystem) with updated software, improved noise performance, and a redesigned battery interface. Inogen consolidated production around the Rove 6 to simplify the supply chain.
That is the manufacturer-side explanation. From a buyer's perspective, the practical fact is that the G5 is no longer the active Inogen product in 2026 and is no longer the right answer to the question "what should I buy?"
What changed in 2026 for current G5 owners?
If you already own a G5, nothing immediately changes. Your unit still works, your prescription still applies, and Main Clinic Supply continues to provide Factory-Certified service. Sieve beds, batteries, and particle filters remain available, with one important caveat.
G5 batteries, cases, and accessories
All G5 batteries, AC/DC power adapters, carry bags, backpacks, and shoulder bags remain in production and are fully compatible with the Inogen Rove 6. If you upgrade from a G5 to a Rove 6, your existing accessories carry over. This is one of the few cases in the POC market where an upgrade does not require buying a new accessory ecosystem.
If you are buying replacement accessories for an existing G5, Main Clinic Supply stocks every G5-compatible part in our Rochester, Minnesota facility for prompt shipment.
What this means for you right now
"New" Inogen G5 listings in 2026 are not what they appear to be
Inogen stopped manufacturing the G5 on March 31, 2025. Any listing in 2026 marketing a brand-new G5 is selling old stock with aging sieve beds, or counterfeit hardware.
Best replacement paths in 2026
Three units are the right answer to "I need a portable oxygen concentrator in 2026, and the G5 is no longer the right choice."
Vita-Ox HD7
The seven-setting upgrade option. 4.37 lbs, 1,400 ml/min peak output (more than both the Rove 6 and P2-E6), 2.8-inch full-color LCD, 5-year device warranty with 2-year user-replaceable sieve bed warranty, $2,295. The Vita-Ox HD7 is the right choice for patients who want the most setting headroom for prescription progression, the longest standard warranty in the class, and a sieve bed that the owner can replace without shipping the unit back to a manufacturer.
Inogen Rove 6
The direct successor. Six pulse settings, 4.8 lbs with standard battery (5.8 lbs with extended), 1,260 ml/min peak output, monochrome LCD, full backward compatibility with G5 batteries and accessories. Pricing is $2,995 standard and $3,215 extended. The Rove 6 is the right choice if your existing G5 accessory investment is significant and you want to preserve it without disruption.
Rhythm Healthcare P2-E6
A six-setting alternative to the Rove 6. 4.37 lbs, 1,200 ml/min peak output, 2.8-inch full-color LCD, $2,995. The P2-E6 matches the Rove 6 on settings, beats it on weight and display, and comes in at a lower price. Does not use Inogen-compatible accessories.
Frequently Asked Questions
When was the Inogen G5 discontinued?
Inogen officially ended G5 production on March 31, 2025. New G5 units have not been manufactured since that date. The G5 was replaced by the Inogen Rove 6, which began shipping in 2024.
Can I still buy a brand-new Inogen G5 in 2026?
No. Any unit being marketed as a "new" Inogen G5 in 2026 is either old stock that has been sitting in a warehouse since 2024 or earlier, or a counterfeit. Old stock units have aging sieve beds that begin degrading the day they are manufactured, regardless of whether the unit has ever been used. Counterfeits are not Inogen products at all.
Are G5 batteries and accessories still available?
Yes. Inogen continues to manufacture G5-compatible batteries and AC/DC power adapters because all G5 batteries and accessories are forward-compatible with the Inogen Rove 6. Particle filters and sieve beds are available while supplies last, then no longer.
Is Main Clinic Supply still servicing the G5?
Yes. Main Clinic Supply is a Factory-Certified Inogen Service Center and continues to provide certified repairs, diagnostics, and parts service for the Inogen G5 in 2026. Sieve bed replacement, battery service, and most common G5 issues are handled in our Rochester, Minnesota facility.
What is the best replacement if my G5 is failing?
Three options. The Inogen Rove 6 is the direct successor with the same six-setting range and full backward compatibility with G5 batteries and accessories. The Rhythm Healthcare P2-E6 matches the Rove 6 on settings and weight at a lower price. The Vita-Ox HD7 adds a seventh pulse setting, lighter weight, higher peak output, a full-color display, and a longer warranty for less than the Rove 6.
Should I buy a used G5 in 2026?
Only from a certified service provider that has verified the sieve bed condition and warranties the unit. A G5 purchased from a private seller or unverified online listing is a sieve-bed lottery. The cost of replacement sieves plus battery refurbishment can exceed the gap between the used G5 price and a new Rhythm P2-E6 or Vita-Ox HD7.
