Oxlife Liberty2 Portable Oxygen Concentrator (Open Box)

Continuous 0.5–2.0 LPM + Pulse 1–10

This Oxlife Liberty2 Portable Oxygen Concentrator (Open Box) is a brand-new unit that has never been used on a patient.
It was opened strictly for photography, media content, and video demonstrations—not for clinical use, rental, or testing.

Because the package was opened, you receive a massive $700 USD discount, making this one of the best-value continuous-flow POCs available today.

With continuous flow from 0.5 to 2.0 LPM and pulse settings 1–10 (8–80 mL), the Liberty2 offers one of the widest therapy ranges in the portable category—perfect for users who need higher flows without sacrificing mobility.

At only 6.36 lb and FAA-approved, it’s ideal for daily use, travel, appointments, and long trips. Charging is fast (<2.5 hours), and real-world battery runtime reaches up to ~4.5 hours depending on your setting.

A color LCD, simple keypad, and DNA® connectivity (where enabled) make it one of the most user-friendly advanced portable concentrators on the market.
