Founded in 2001, Inogen is a relatively young company but has a significant market position. Unlike other manufacturers looking for agents to sell, Inogen also sells or leases oxygen concentrators directly to consumers. In 2017, Inogen sold or leased more than 362,000 oxygen concentrators to consumers.
 
In the highly homogeneous oxygen generator industry, it is not easy for the products to catch people's attention and be configured well enough. Inogen At Home is the most differentiated 5L medical benchtop oxygen concentrator on the market, with a weight of only 8.17kg while ensuring 5L oxygen output and 90% oxygen concentration, which is nearly half lighter than the Inogen At Home visionaire 5. At Home is also outstanding in terms of ease of use, with fewer buttons and simple operating logic. The price of At Home in the US market is $1495, which is more expensive than similar products.
 
There are three models of the Inogen One series portable oxygen concentrator: G2, G3 and G4, and the heaviest G2 is only 3.18kg. All three products have top-notch quietness, but there is a big difference in battery life, with the G2 being able to reach 4 hours on a single battery, while the G3 and G4 are no more than two hours. At present, Inogen has not yet entered the Chinese market, and if you want to buy it, you need to seek purchasing agents.
