Go for a tankless oxygen unit today with the Inogen One G4 portable oxygen concentrator. If you find your oxygen therapy restrictive, this POC can provide you with maximum freedom and independence in doing things you like, anywhere and anytime you want. Weighing only 2.8 pounds, the Inogen One G4 became one of the smallest, lightest, and most portable concentrators.

This oxygen concentrator supports an Intelligent Delivery System, which produces oxygen once it detects your breath rate. Wasting oxygen is not in its vocabulary because it only delivers them when necessary. If your oxygen therapy needs a night usage of POC, this unit can also be your savior because it has more sensitive breath detection during sleep.

Inogen One G4 can address your varying oxygen needs with three pulse settings up to 2.7 to 5 hours. You can opt for double batteries to enjoy its benefits until the 10th hour of performance. Being FAA-approved, using this POC is also possible in air travel.

Home equipment providers and patients can also use this unit's Bluetooth Connect Technology, which enables you to monitor, track, and manage your fleet of POCs (gestione su flota de POC). This feature is also helpful for checking the unit's status and reviewing maintenance reports. Luckily, all these features are in one click on your smartphone!
