Portable Oxygen Concentrators: Which One is Right for You?

At Respocare, we understand that choosing the right oxygen concentrator is an important decision.

These devices offer both convenience and reliability, ensuring that our patients receive the best oxygen therapy solutions.

Our experience in the oxygen therapy industry has shown us that quality matters above all else. We refuse to compromise on the value and performance of the devices we provide. Both the iGo2 and the Inogen G5 represent the best in their class, offering excellent performance while meeting the needs of patients who require oxygen support to maintain their health and independence.

Why Rent the iGo2 DeVilbiss?
If you’re not ready to purchase a concentrator or need one for short-term use, the iGo2 DeVilbiss is a great option. We offer rental options, making it perfect for those who need flexibility. The iGo2’s SmartDose technology automatically adjusts the oxygen dose based on your breathing, ensuring you get the right amount of oxygen at any activity level, all while preserving battery life.
Inogen G5: A Long-Term Investment
The Inogen G5 is ideal for patients looking for a long-term solution. Its 16-cell battery offers extended life—up to 13 hours depending on usage—making it a reliable companion for active users who need continuous oxygen support. Its higher flow rate of up to 6 LPM also meets the needs of patients who require more oxygen. Although we do not rent the Inogen G5, it’s an excellent investment for those who need a dependable, long-term concentrator.
Seive Bed Warranty
Both the iGo2 and Inogen G5 come with a 1-year warranty on the sieve beds, which are essential components of any oxygen concentrator. These filters are responsible for separating nitrogen from oxygen, and their durability is crucial to maintaining the device's efficiency.
Conclusion: Quality Without Compromise
At Respocare, we believe that our patients deserve the best. Whether you choose the iGo2 DeVilbiss with its rental option and SmartDose technology or the Inogen G5 with its long battery life and higher flow rate, you can be assured that you are getting a high-quality, reliable device.
