Inogen Oxygen Concentrator Review – Forbes Health

Unlike traditional compressed gas cylinders (tanks filled with oxygen), oxygen concentrators provide a safe source of oxygen-enriched air using ambient air, which is a mixture of 21% oxygen and 78 % nitrogen. An oxygen concentrator draws ambient air into a cylinder which filters dust, bacteria and other air particles and absorbs nitrogen, resulting in concentrated oxygen (90% or more).

There are two types of oxygen concentrators: portable and stationary. Portable models typically use the pulse delivery mode in which oxygen is delivered when the user begins to breathe. Meanwhile, stationary models have a continuous flow of oxygen.

Inogen currently offers three portable oxygen concentrators – the Inogen One G3, G4, and G5 – and a stationary model called the Inogen at Home. Below is a summary of their main features.

Customization options and special features

Splurge on the dual battery for Inogen One models if you want more flexibility with your time away from home. A dual battery can run an Inogen portable oxygen concentrator for the duration of a baseball game, according to the company.

Apps and accessories

The Inogen One G3, G4, and G5 portable oxygen concentrator models include a battery, AC/DC power cables, shoulder strap, and protective bag for the device. The devices require a nasal cannula to deliver oxygen. Your health insurance benefits may include a free supply of nasal cannulas, so check your policy to be sure.

A backpack and a transport trolley are also available for the portable models.

An external battery charger is also available, allowing you to charge multiple single and dual batteries at once.
