- Six Pulse Flow Settings— One of the distinguishing factors about the G5 as opposed to earlier generations of the Inogen One is that they’ve added a sixth flow setting to increase the amount of oxygen. While users of lower flow oxygen may not see this as a huge benefit in the short term, the reality is that having more options is always better, especially as ailments worsen or conditions change. For example, someone with a chronic lung condition may be perfectly suited with a three-level flow setting, but the need for oxygenation could increase to a six while exercising.
- Expanded Battery Life— If I’m looking for a portable oxygen concentrator, I’m looking for the ones that will provide the most amount of freedom; and a big part of this is battery life. The G5 goes beyond the already-impressive 10 hours offered in previous models, bumping the battery life to 13 hours using a double battery (more on this later). 13 hours offers ample use time outside of the home, which really sets the G5 apart as a heavy hitter in the portable concentrator market.
- Relatively Lightweight— You’ll notice I didn’t say definitively that the G5 is lightweight; the unit weighs in at less than five pounds, which for some people may actually be too heavy to carry around all day. I list its weight as a pro, however, because for the amount of function and features the G5 packs into those five pounds, it really is a compact and lightweight unit.
- Perfect for Travel— Between its weight and the amount of battery life it affords, the G5 is already a great portable unit to carry around all day. But, the fact that it’s also Federal Aviation Administration (FAA) approved means that it’s an excellent option for those looking for an oxygen concentrator they can take when they travel.
- Reduced Noise Level— One common complaint people have about oxygen concentrators is their operating volume, which can be noisy enough to impact a good night’s sleep. The G5 has improved upon their previous models, quieting the device to 38 decibels on its level two setting, which is one decibel quieter than other Inogen One units. 38 decibels is what audiologists would rank as a soft sound, so it shouldn’t impede day-to-day activities too much. While a drop from 39 to 38 obviously isn’t a drastic reduction, the difference is noticeable, and it may just help an older user sleep a little easier.
