Lightweight. Compact. Fits your lifestyle.

Inogen G5 Lifestyle

The main problem with older portable oxygen concentrators was the weight. These POCs used to be extremely heavy, bulky and difficult to carry around even within a home setting. This fact made patients become more isolated and they could not participate in social gatherings, because of a heavy and cumbersome oxygen concentrator. Today, Inogen revolutionizes the way these concentrators look and feel. With Inogen One G5 you get a truly stylish, compact and user-friendly portable oxygen concentrator which comes with a modern design.

You can take it with you wherever you go- to the park, to the restaurant, traveling by plane, by car or visiting your relatives. This portable oxygen concentrator will help you follow an active lifestyle and routine, where you are not hindered by the use of a bulky concentrator that you simply cannot carry around.

Inogen One G5 comes with long-lasting batteries to give you more freedom of movement and careless days and nights. When used on a single battery, the machine can operate up to 4.5 hours on the setting level of 2. When used on a double battery, the operation time will double- and you get 9 hours of continuous operation on a setting of 2. These are Lithium-Ion batteries of exceptional quality and they also come with a recharge time that is faster than average. It takes about 4 hours to get a full charge for the small battery and approximately 8 hours for a full charge on the large battery.

Extremely quiet. Perfect for a good night’s sleep

Yet another big issue with older POCs was that they were extremely noisy. Patients and bed partners were woken up in the middle of the night by loud noises coming from the machine. All this has changed by now because Inogen One G5 has a noise level of only 39 Decibels, which can be translated into a normal level indoors conversation. This fact helps patients feel more comfortable in social settings for example because they will not have to worry about their POC being too loud and attracting all the attention. Inogen One G5 Portable Oxygen Concentrator is indeed the perfect solution for quieter environments and also for sleeping. Both patients and bed partners can now get a restful and quiet night of sleep, without interruptions.

My g5 makes a bothering thumping sound every 8-10 seconds that can be heard any where in a normal sized room and would certainly be to loud for church or even on an airplane, this is not normal is it?

Every concentrator be it stationary or portable will make the sound you describe as it is the process where oxygen and other gases are released to the atmosphere or the oxygen storage tank. If you set the portable concentrator of the floor the sould should be very low and should not bother anyone. I would assume you are either noise sensitive or the machine needs to be sent in for repair.
