Before you order — confirm these
The G5 is a pulse dose concentrator only — it does not deliver continuous flow. Not appropriate for prescriptions specifying a continuous flow rate (LPM). Pulse dose during sleep requires physician guidance. Battery life specs are manufacturer best-case figures — in SW Florida summer heat, plan for 70-75% of published runtime. 866-218-0902
Why the G5 Is the Most Prescribed Portable in America
Most Prescribed Portable in the United States
The G5 is the most prescribed portable because tens of thousands of physicians have used it with enough patients, over enough years, to trust it without reservation. That depth of clinical validation is something no newer unit can match. When your pulmonologist recommends a unit, this is often the one they have in mind.
8-Year Service Life · 13 Hours · User-Replaceable Sieve Beds
An expected 8-year service life with up to 13 hours on the double battery and user-replaceable sieve beds. The G5 is built to be a long-term investment. Over its service life, the cost per day of ownership is among the lowest of any portable concentrator available.
Intelligent Delivery · Inogen Connect App · FAA-Approved
Intelligent Delivery Technology monitors your breathing rate in real time and adjusts bolus size and timing accordingly. The Inogen Connect app provides Bluetooth monitoring for patients and caregivers. FAA-approved with well-established airline documentation that gate agents recognize.

Frequently Asked Questions
Both are 6-setting pulse dose concentrators from Inogen at nearly identical weights. The Rove 6 is newer, quieter (37 dBA vs. 40 dBA), and has the longest extended battery life in the category. The G5 has the longer clinical track record and is the most widely prescribed portable in the United States. If you want the most proven unit, the G5 is the answer. If you want the latest technology, the Rove 6 is worth considering. 866-218-0902.
The G5 is clinically validated for 24/7 waking use. Whether it is appropriate for nighttime use depends on your specific prescription and breathing pattern during sleep. Your physician's guidance on nighttime use is essential before using any pulse dose unit overnight. 866-218-0902.
In Southwest Florida summer heat, lithium-ion batteries perform at roughly 70-75% of published specs. The double battery rated at 13 hours will deliver approximately 9-10 hours at setting 2 on a hot day. Build your day around that number. For all-day outings, carry the single battery as a backup or identify a charging stop in advance. 866-218-0902.
Yes — FAA-approved for domestic commercial flight with well-established airline documentation. The concentrator checks at the gate door; batteries must be carried in the cabin. Bring enough battery for 150% of total travel time. Call the airline at least 48 hours before your flight. 866-218-0902.
Yes. Our 10-Day No-Risk Trial lets you take the G5 home and use it in your actual life for 10 days. If it is not the right fit, bring it back and we will exchange it. No restocking fee, no fine print. Walk-ins welcome at all five SW Florida locations. 866-218-0902.
