Courtney Sornberger is a Certified Oxygen Specialist at Main Clinic Supply with over 13 years of experience.

If your doctor has prescribed supplemental oxygen, a portable oxygen concentrator (POC) can give you back the freedom that bulky oxygen tanks often take away.

Unlike traditional oxygen tanks, POCs allow you to move freely at home, run errands, travel, and engage in daily activities with greater ease.

As an oxygen equipment specialist with over a decade of experience, I've witnessed the remarkable difference POCs make in my patients' lives compared to cumbersome oxygen tanks. They are safer, more convenient, and cost-effective in the long run.

However, with numerous models available, selecting the right POC requires careful consideration of factors like oxygen delivery settings, battery life, portability, and sound levels.

After rigorously testing the top models on the market, I've chosen the 5 best portable oxygen concentrators of 2024 that I confidently recommend to my patients seeking top-rated solutions for active, unrestricted living.
