Inogen One G4 Portable Oxygen Concentrator


Last Sold  5 sold in last 6 hours

Inogen One G4 Portable Oxygen Concentrator is a lightweight portable oxygen machine made by one of the top manufacturers in the industry. The combined weight of the Inogen carry bag, the Inogen One G4 concentrator, and Inogen battery is less than four pounds, making the Inogen G4 less cumbersome to carry along. Its small size and low weight reduces fatique and allows the user to more discretion. The Inogen One G4 System provides pulse flow oxygen in a selectable range of 1 to 3 with an average sound of only 40 decibels, which is a significantly lower level than human conversation. The small, lightweight, and discreet design of this portable Inogen machine it a top competitor in the pulse flow oxygen market. Many users choose to pair this oxygen concentrator with Salter Labs’ Nasal Cannula for Adults.

The Inogen One G4 Oxygen Concentrator incorporates dual-exhaust and dual-intake technology, providing maximum heat dissipation to keep the O2 device running cooler and longer. This machine can operate from three separate power sources: battery, DC power (car, truck, RV, boat), or AC power (found in homes). AC power is also used to recharge the battery. The Inogen One G4 machine is designed to operate 24/7 to meet the needs of the oxygen patient. The user may select between two Inogen One battery options—the standard single battery or the upgraded double battery. The Inogen One double battery lasts twice as long between recharges as the Inogen One single battery.
