Why this concentrator

Six settings, up to 1,200 mL/min

The E6 reaches setting 6 and 1,200 mL/min of oxygen — real headroom for higher prescriptions, altitude, or exertion that a 5-setting portable can't cover.

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.

Frequently asked questions

What does Certified Pre-Owned mean?

Every certified pre-owned P2-E6 is a used unit that's been professionally inspected, function-tested, and reconditioned to factory standard, with critical parts replaced where needed. It ships ready to use and is backed by a 1-year warranty by American Oxygen.

Is it covered by a warranty?

Yes. This certified pre-owned P2-E6 is backed by a 1-year warranty by American Oxygen, plus our local support. Its sieve columns are covered for one year and are simply replaced when oxygen purity starts to drop — and genuine Rhythm parts and columns stay available so your unit keeps running for years.

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.

Why buy certified pre-owned instead of new?

You get the same six-setting P2-E6 performance — up to 1,200 mL/min, 4.37 lb, FAA-approved — for less than a new unit, inspected and function-tested, and backed by a 1-year warranty by American Oxygen. It's the practical way to get higher-setting oxygen without paying new-unit price.
