No prescription or special documentation is required to purchase the SJ-OX1C. That said, we always recommend checking with a qualified professional to help determine the flow setting that fits your needs.

Please check with your airline directly, as approval requirements and documentation can vary by carrier. We're happy to provide the technical specifications you may need for their review.

The SJ-OX1C runs quietly enough for everyday use, including at night — most users describe it as a soft, steady hum that fades into the background rather than a disruptive noise.

We recommend consulting with a qualified professional to identify the setting that's right for you — the large touch screen then makes it simple to dial in and monitor your exact setting.

Each battery delivers up to 110 minutes of use for model SJ-OX1C, and the machine works with AC power, car charging, and battery power. The included carrying bag holds up to 4 batteries, so you can extend your time out and about as needed.

The molecular sieve bed is replaceable, which is the main wear component — this lets you refresh performance without replacing the entire unit, helping the machine stay reliable for 5+ years.

Our concentrators work by drawing in the surrounding air, which is naturally made up of about 21% oxygen and 78% nitrogen. The air passes through a filtration system and a molecular sieve, which separates out the nitrogen and other gases. What's left is a concentrated stream of purified oxygen, delivered to you through the nasal cannula in a steady, continuous flow. Since the machine draws directly from the air around it, there's no need to store or refill oxygen tanks — it simply runs as long as it has power.
