Why this concentrator

All-day single battery, 4.37 lb

Up to 5.4 hours on setting 1 from a single internal battery, in a 4.37 lb body you can carry all day. Carry a charged spare and you're covered for a full day out.

FAA-approved & FDA-cleared

The E6 is FAA-approved for commercial flights, so it flies in the cabin with you. It's a genuine, FDA-cleared prescription medical device — not a grey-market import.

Medical-grade oxygen you can count on

90% ± 3% concentration at every one of the six settings — verified output, not the drifting purity of a cheap import.

Frequently asked questions

What does “Open Box” mean for the Rhythm P2-E6?

An Open Box Rhythm P2-E6 is a brand-new, unused unit — the sealed box was opened only for photos or display and then set aside. It has never been used on a patient, it's genuine and current-generation, and it carries the full Rhythm factory warranty. You simply pay less than for sealed stock.

How long does the P2-E6 battery last?

Up to 5.4 hours on setting 1 from the single battery. Higher settings use more oxygen and shorten runtime — about 1.7 hours at setting 6. Many customers carry a charged spare for long days.

Is the P2-E6 approved for airline travel?

Yes. The P2-E6 is FAA-approved for use on commercial flights and travels in the cabin with you. Airlines typically ask for advance notice and enough charged batteries for about 150% of your flight time.

Do I need a prescription to buy it?

Yes. The P2-E6 is an FDA-cleared prescription medical device. American Oxygen can help you understand what's needed — just ask when you call.

How is the E6 different from the P2 or the E7?

The P2 has five settings and 1,000 mL/min; the E6 adds a sixth setting and 1,200 mL/min; the E7 goes to seven settings and 1,400 mL/min. All share the same 4.37 lb body — choose by the top setting your prescription needs.

Is this a new unit with warranty?

Yes. American Oxygen is an authorized Rhythm dealer, and every Open Box Rhythm P2-E6 is genuine and unused, backed by the full Rhythm manufacturer warranty — 3 years device, 1 year sieve columns, 1 year battery — plus our local support.
