O2 concepts Liberty2 Portable Oxygen Concentrator

O2 Concepts Oxlife Liberty2® Portable Oxygen Concentrator — 2 LPM Continuous Flow, Wearable Design

The O2 Concepts Oxlife Liberty2® represents the next generation of portable oxygen therapy — combining true continuous flow oxygen up to 2.0 LPM with an industry-leading pulse dose capacity in a lightweight, wearable design that weighs just 6.35 lbs. For patients who need continuous flow oxygen on the go but want the freedom of a truly wearable, hands-free concentrator, the Liberty2 is the most advanced solution available.

Built on O2 Concepts’ proven platform of continuous flow portable technology, the Liberty2 is engineered for 24/7 use — reliable enough to serve as your primary oxygen source, compact enough to wear across your body or carry in a shoulder bag, and powerful enough to meet a broad range of therapeutic oxygen prescriptions.

True Continuous Flow in a Wearable Form Factor

The Liberty2’s defining advantage is delivering true continuous flow oxygen at 0.5–2.0 LPM in a package light enough to wear. Most wearable or ultra-compact POCs are limited to pulse dose only — the Liberty2 breaks that barrier, making it the ideal choice for patients who:

• Require continuous flow oxygen during sleep or rest
• Have irregular breathing patterns that make pulse dose unreliable
• Are prescribed continuous flow by their physician but want a wearable portable option
• Need a single device that handles both active daytime use (pulse dose) and nighttime/rest use (continuous flow)

Key Features & Specifications

• Continuous Flow: 0.5–2.0 LPM (true continuous flow)
• Pulse Dose Settings: 1–10 (industry-leading pulse dose capacity)
• Weight: 6.35 lbs
• Design: Wearable — shoulder bag / cross-body carry style for hands-free use
• 24/7 Capable: Engineered for continuous around-the-clock use
• AC & DC Power: Operates on standard household current (AC) and 12V DC (car adapter) for travel
• FAA Approved: Approved for use on commercial aircraft
• Warranty: Concentrator: 3 years | Sieve tubes: 1 year | Battery: 1 year
• FDA Classification: Class II Medical Device

Industry-Leading Pulse Dose Capacity

In addition to continuous flow, the Liberty2 offers pulse dose settings 1–10 — one of the highest pulse dose ranges available in a wearable portable concentrator. This gives patients and clinicians maximum flexibility to titrate oxygen delivery to the patient’s activity level and therapeutic needs, using pulse mode during active periods to extend battery life and switching to continuous flow during rest or sleep.

Wearable Design — Built for Active Living

At just 6.35 lbs, the Liberty2 is designed to be worn across the body in a shoulder bag or carry case — keeping both hands free for daily activities. Whether you’re walking, shopping, traveling, or attending appointments, the Liberty2 moves with you without the bulk or weight of a rolling concentrator or the hassle of oxygen tanks.

Its compact, wearable form factor makes it one of the most travel-friendly continuous flow POCs available — fitting easily in overhead bins, under seats, and through airport security.

Single-Source Solution for 24/7 Therapy

The Liberty2 is engineered to be a patient’s single oxygen source — replacing both a stationary home concentrator and portable tanks for patients prescribed up to 2 LPM continuous. Its durable construction and proven O2 Concepts platform are built for year-after-year reliability, backed by a 3-year concentrator warranty.

Who Is the Liberty2 For?

• Patients prescribed continuous flow oxygen at 1–2 LPM who want a wearable, hands-free portable solution
• Active patients who travel frequently by car or airplane
• Patients who require oxygen during sleep and need a lightweight continuous flow option
• Patients who want a single device for both daytime activity (pulse dose) and nighttime rest (continuous flow)
• Anyone transitioning away from oxygen tanks who wants a compact, refill-free alternative

Liberty2 vs. Oxlife Independence — Which Is Right for You?

• Liberty2 (this model): 2 LPM continuous flow, 6.35 lbs, wearable design. Best for patients prescribed up to 2 LPM who prioritize portability and wearability.
• Oxlife Independence: 3 LPM continuous flow, 16.7 lbs, rolling cart design. Best for patients prescribed up to 3 LPM who need higher flow and are comfortable with a rolling unit.
