Real customers who reclaimed their mobility with our mini oxygen concentrators. You can, too.
The Oxlife Liberty 2 combines true continuous-flow oxygen up to 2.0 LPM with pulse-dose settings 1 through 10 in a compact, carryable system. For people who require continuous flow, it provides an alternative to relying on a larger rolling concentrator or portable oxygen tanks.
Most small portable oxygen concentrators provide pulse dose only. The Liberty 2 stands apart by providing both continuous flow and pulse dose in a compact system designed to be carried.
Provides continuous-flow oxygen from 0.5 to 2.0 liters per minute for users whose prescribed needs cannot be met by a pulse-only system.
Its compact carry system gives continuous-flow users an alternative to pulling a larger oxygen concentrator behind them.
Operate the Liberty 2 from approved household power, compatible vehicle power, or its removable rechargeable battery.
Designed for 24/7 operation when used according to the prescribed oxygen mode, setting, and manufacturer instructions.
The battery can be changed by the user, allowing additional charged batteries to be carried for longer periods away from household or vehicle power.
The Liberty 2 meets applicable requirements for portable oxygen concentrator air travel. Airline notice, documentation, and battery rules still apply.
The Liberty 2 fills an important gap between lightweight pulse-only concentrators and larger continuous-flow machines.
The Liberty 2 is an excellent option for the right oxygen requirement, but it is not automatically the best system for everyone.
Someone who needs more than 2.0 LPM continuous flow may need a higher-output continuous-flow system such as the Oxlife Independence. Someone who requires only pulse-dose oxygen may prefer the much lighter OxyGo NEXT NG or OxyGo FIT Plus.
The correct choice begins with your prescribed oxygen delivery method and setting—not simply the smallest or lightest machine.
The Liberty 2 is designed to make everyday activities easier to manage without coordinating portable tank deliveries, exchanges, or refills.
Carry the system to medical appointments, stores, restaurants, and other everyday destinations without managing several oxygen cylinders.
Use one concentrator at home, in the vehicle, and at your destination while staying connected to everyday activities and the people who matter.
Take a continuous-flow option away from home without transporting a large stationary concentrator or relying entirely on oxygen tanks.
The Liberty 2 provides two different oxygen-delivery modes. Pulse settings and continuous-flow liters per minute are different measurements and are not interchangeable.
Continuous flow delivers oxygen steadily throughout the breathing cycle, whether or not the concentrator detects an inhalation.
This mode is commonly considered by people whose prescription specifically calls for continuous-flow oxygen.
Pulse dose delivers a measured amount of oxygen when the device detects the beginning of an inhalation.
Pulse-dose settings are machine settings and are not equal to continuous-flow liters per minute.
Because the Liberty 2 provides continuous-flow oxygen up to 2.0 LPM, it may be used with compatible CPAP or BiPAP oxygen setups when prescribed and configured correctly.
This can be especially useful for vacations, visits with family, and other overnight trips when transporting a larger stationary concentrator would be inconvenient.
CPAP and BiPAP compatibility depends on the prescribed oxygen flow, sleep device, oxygen connection, and your healthcare provider's instructions.
Keep any backup oxygen supply recommended by your healthcare provider available during overnight use.
The Liberty 2 can operate from approved AC household power, compatible DC vehicle power, or its removable rechargeable battery.
The Liberty 2 can operate from compatible vehicle power and is designed for portable oxygen use during airline travel when applicable airline and battery requirements are followed.
The standard system includes the essential equipment needed for home, vehicle, and portable operation.
Package contents can vary. Review your written order to confirm included batteries, accessories, and warranty coverage.
Each model serves a different oxygen requirement and mobility priority. The right choice depends first on whether your prescription requires pulse dose or continuous flow.
