Why this concentrator

Two ways to breathe, one unit

Continuous flow from 0.5 to 2.0 LPM in 0.5 steps, plus ten pulse settings with adaptive dosing. Use continuous for sleep or steady needs and pulse on the move — a single unit covers both as your day changes.

FAA-approved, FDA-cleared & made in the USA

The Liberty2 is FAA-approved for commercial flights, so it flies in the cabin with you. It's a genuine, FDA-cleared prescription medical device built in the USA — not a grey-market import.

In short

It's a genuine, U.S.-made, FDA-cleared, FAA-approved portable that delivers both continuous flow (0.5–2.0 LPM) and ten pulse settings at 6.35 lb, sold by American Oxygen (an authorized O2 Concepts dealer) with the full factory warranty.

Frequently asked questions

What does “Open Box” mean for the Liberty2?

An Open Box Liberty2 is a brand-new, unused unit — the sealed box was opened only for photos or display, then set aside. It has never been used on a patient, it's genuine and U.S.-made, and it carries the full O2 Concepts factory warranty. You simply pay less than for sealed stock.

How long does the Liberty2 battery last?

In pulse mode, up to 4h 30m on setting 1. In continuous mode, up to about 3h 15m at 0.5 LPM, coming down as the flow rises. The battery is single-bay and user-swappable — carry a charged spare for longer days.

Is the Liberty2 approved for airline travel?

Yes. The Liberty2 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 Liberty2 is an FDA-cleared prescription medical device. American Oxygen can help you understand what's needed — just ask when you call.

Does the Liberty2 really do continuous flow?

Yes. It delivers true continuous flow from 0.5 to 2.0 LPM in 0.5 steps, plus ten pulse settings — unusual in a portable this light at 6.35 lb. That makes it suitable for many steady and sleep needs a pulse-only unit can't serve.

Is this a new unit with warranty?

Yes. American Oxygen is an authorized O2 Concepts dealer. Every Open Box Liberty2 is a genuine, unused, U.S.-made unit backed by the full O2 Concepts manufacturer warranty — 3 years device, 1 year sieve columns, 1 year battery — plus our local support.
