Inogen One G4 Portable Concentrator Product Overview Back to top
Introducing the smallest portable oxygen concentrator from the most popular brand, Inogen. The Inogen One G4 is capable of providing oxygen delivery in an unbelievable small and quiet package. With flow settings from 1-3, the Inogen One G4 is designed to increase independence for most users 24/7. It can be charged at home or on the go - giving you the freedom you deserve.
The Inogen One G4 provides you with 3 separate oxygen flow settings. It also includes Inogen’s Intelligent Delivery technology, which sets it apart from the competition. This innovative system rapidly detects a breath and delivers oxygen in the first 400 milliseconds. This is critical because this period is when the most gas exchange occurs in the lungs. Delivering oxygen at the start of a breath ensures that the oxygen is used more efficiently by your body.
At only 40 decibels, the G4 produces less noise than a normal indoor conversation. This means you won’t disturb others when you use your oxygen concentrator and will feel more comfortable in social settings. It’s also great in quiet environments when you want to be unobtrusive.
Furthermore, Intelligent Delivery accurately detects your breathing rate and adjusts the oxygen level provided accordingly. If you’re exercising or physically active, the unit will provide smaller, quick bursts of oxygen to satisfy your energy needs. However, during rest or sleep the system provides larger oxygen boluses more slowly to correspond with your decreased rate of respiration. This means the G4 can be effectively used during sleep at night, an area where many other portable oxygen concentrators fall short. With the G4, you won’t need separate oxygen systems for the day and night.
The Inogen One G4 comes with a 3 year warranty covering the concentrator. There’s also a 1 year warranty that covers the sieve beds and accessories, so your entire system is protected. The starter package comes with the Inogen G4 unit, single battery, AC power supply, DC power cable, carrying bag, cannula, and manual. Please ask about our Inogen G4 packages if you require more batteries or accessories.
I have been using this unit for 4 months now. I has not skipped a beat.... I bought the bigger battery but I have never even go close to using all of it.. I put it on charge when in my truck.. and on charge when home or in the office... I have gone 5 hours on a setting of 2 and still had 25% left.. I find it amazing how this little unit can do what it does and be so quiet at the same time.

Runs hot and 3L Pulse
This unit is great if you need 2L on pulse while mobile; easy to carry and quiet. Very warm as the exhaust is vented on both sides...so great in the winter, not so great around the house/office. Buying a lighter unit is great unless your situation gets worse, then you have to upgrade and upgrade again.
