Inogen One G5 Specifications
Precise Oxygen Flow and Concentration Levels
The Inogen One Rove 5 offers six oxygen flow settings, ranging from 1 to 6, to meet varying oxygen therapy needs. This flexibility allows you to adjust the oxygen delivery based on your activity level and prescription requirements. Whether you’re engaging in low-intensity or more strenuous activities, the G5 has you covered.
It delivers oxygen with a consistent concentration level of 90% ± 3% at all pulse settings, ensuring you receive the precise amount of oxygen needed to support your respiratory system. This reliable oxygen concentration gives you peace of mind, knowing that you are getting optimal oxygen therapy.
Important: For personalized oxygen delivery, each flow setting can be fine-tuned based on the patient’s breathing rate and other physiologic factors. We recommend the patient to use a pulse oximeter to monitor blood oxygen levels. From there, the oxygen flow settings can be adjusted for various activities.
If you do not have a pulse oximeter, Main Clinic Supply will provide one at no charge. It is important for you to have one of these small devices to fine-tune your oxygen therapy to your exact needs!

The Inogen One G5’s Standout Features
Leading Performance and Portability
The Inogen One G5 offers the longest battery life and delivers some of the highest oxygen outputs available in a portable concentrator.
Its compact design and user-friendly interface are rapidly gaining popularity, providing you with the freedom to maintain your active lifestyle.
Whether you're on a trip, running errands, or staying active at home, the G5 adapts effortlessly to your daily routine.
Intelligent Delivery Technology®
The Inogen One G5 incorporates Intelligent Delivery Technology, the result of years of cutting-edge innovation in portable oxygen systems.
This technology ensures a precise dose of oxygen is delivered exactly when you need it, whether during daily activities or restful sleep. The G5 automatically detects each breath and provides the appropriate amount of oxygen instantly.
During sleep, when your breathing naturally slows, the G5’s sensitive triggers and adaptive pulse volume ensure you continue to receive the oxygen you need, even with shallow breathing.
Designed for Travel & FAA-Certified
The G5 transitions smoothly from home use to travel, making it an ideal companion wherever life takes you. It’s portable, easy to carry, and the AC power supply automatically adjusts to various voltage requirements around the globe. Plus, it’s fully compliant with FAA guidelines for air travel.

Frequently Asked Questions
Have questions? Learn more about how our products can support you.
We guarantee our price to be the lowest of any Inogen One Authorized Dealer. Be careful; there are only two of us in the USA! The others are buying somewhere other than Inogen One, the manufacturer. In some cases, these are used machines that are represented as "New". We always strive to offer good value and have special deals on our oxygen concentrators. But if you’re struggling to fit the oxygen concentrator, you need into your budget, or have found a competitive price elsewhere, speak to us. We always put our customers’ needs before profits.
Medicare will not purchase any Inogen One System, as Medicare classifies these as “Luxury Items.” Most insurance companies take the same stance as Medicare. However, a few insurance companies will reimburse all or part of your Inogen Oxygen system after purchasing and submitting the required claim forms. Inogen One Systems are the best on the market; owning the very best in portable oxygen is worth the investment.
Here at Main Clinic Supply, we believe that everyone should have the chance to live their lives to the fullest! While many insurance companies and programs classify our state-of-the-art portable oxygen concentrators as "luxury items," we know they are anything but. As an oxygen user, you deserve access to oxygen equipment that will allow you to stay active and healthy. Because of this, we have partnered with PayPal Credit and CareCredit to help make sure that every oxygen user has the chance to own the very best in portable oxygen and enjoy the freedom and mobility that it brings! Apply or check our options here.
You may fax your prescription for oxygen to us at 1-800-819-7179 or email rx@mainclinicsupply.com. We are also happy to the obtain the prescription for you after you place your order here online.
The Rove 6 (G6) builds on years of improvements to the Inogen G5. Enhancements include an easier-to-grip contoured carry handle and intuitive control panel. Where the Rove 6 really shines is its cutting-edge pulse flow delivery algorithms that closely match oxygen delivery to breathing patterns, further optimizing effectiveness and battery life. It also has slightly lower noise levels.
Free trials are something to be wary of. The majority of medical oxygen dealers share an interpretation of a “New Oxygen Concentrator Machine”, as a machine that has less than 100 hours of previous use. They don’t actually offer you a free trial, just a used machine you are made to think is new. At Main Clinic Supply, new means new, or never used before!
