At a weight of just 2.8 pounds including a single battery, the Inogen One G4 Portable Oxygen Concentrator, released in May 2016, has quickly become a favorite among oxygen users that wish to maintain their active lifestyles. Producing "more oxygen per pound of weight" than other oxygen concentrators currently on the market, according to Inogen, it is designed for continuous use—even while those using it are still on the move.
The Respironics SimplyGo portable concentrator is an innovative unit that simplifies the care and management of oxygen therapy users. The Respironics SimplyGo, like all portable oxygen concentrators, provides pulse dose delivery of oxygen up to 6 liters per minute. However, unlike other POCs, or portable oxygen concentrators, the unit also delivers continuous flow of 2 liters of oxygen per minute. This unique feature sets the SimplyGo apart from other POCs on the market, making it a great choice for almost all oxygen users.
