Known for its small size, light weight, and reliability, the Inogen One G3 has been well-received in the marketplace for many years and is arguably their flagship portable oxygen concentrator. Recently Inogen made several welcome upgrades to their popular Inogen One G3.
First, Inogen increased the oxygen capacity from a maximum of 840 mL per minute to 1050 mL per minute. This increase in oxygen allows for an additional pulse setting. Thus, the new Inogen One G3 provides pulse settings from 1 to 5.
Second, Inogen made the G3 quieter. When reviewing the original Inogen G3 several years ago, I found only one problematic flaw – the noise! The Inogen One G3 had a rather loud purging sound and I could not recommend it for those who are noise sensitive or frequent quiet places, such as the theater. Inogen finally corrected the issue. The new high-flow Inogen One G3 is noticeably quieter than the original version.
Finally, the particles filters have been improved. Previously made of a rubber-type material, the new filters consist of a durable stainless steal mesh enclosed by a plastic frame. These new filters, which are only compatible with the high flow G3, will require less frequent replacement.
