Inogen One G3 Portable Concentrator

The Inogen One G3 is currently among the most compact and lightweight portable oxygen concentrators available, featuring extended battery options for prolonged use. Designed to provide users with a high degree of independence and mobility, this portable oxygen device encompasses all the features of its predecessor, the Inogen One G2, while being smaller in size, lighter in weight, and more efficient in oxygen production. Its a handheld solution that doesnt require a rolling cart, eliminating the hassle of oxygen tank refills and ensuring a continuous oxygen supply.

Operating as a pulse dose portable concentrator, it offers settings from 1 to 5, delivering oxygen at a concentration level of around 90%. Remarkably quiet at just 39 decibels, it can be used discreetly in quiet environments like libraries or churches without causing disturbance. Its user-friendly LCD screen clearly displays flow settings and the remaining battery life.

The Inogen G3 weighs less than 5 pounds with the 8-cell small battery and 5.7 pounds with the 16-cell large battery. Its dimensions are 7.25 inches in height, 3 inches in width, and 8.75 inches in length, making it one of the most wearable concentrators ever created. For convenient transportation, the G3 unit comes with a portable carry bag that can be comfortably worn over the shoulder.
