An In-Depth Look at the Inogen at Home Concentrator

Oxygen therapy users who require a reliable stationary unit that is still easy to use and move around the home when necessary can count on the Inogen at Home oxygen concentrator.

The Inogen at Home oxygen concentrator, which features five flow settings, is not only one of the smallest and lightest units designed for daily use on the market, it consumes less energy than other concentrators. Coupled with its affordable price point, this oxygen concentrator can eventually pay for itself all while providing reliable and precise oxygen therapy.

  • Energy-efficient operation saves money

While standard oxygen concentrators designed for daily use are often large, bulky and unsightly, the Inogen at Home oxygen concentrator is one of the most inconspicuous and attractive units available. Although it is meant for stationary use, its weight — just 18 pounds, 13 pounds lighter than its closest competitor — makes it easy to move around the home, giving users far more independence and freedom. The unit has been designed to operate quietly as well; it registers at just 40 dB, the same as a refrigerator humming or a running desktop computer when operating at flow setting 2.

I love this machine!

I was not excited about having to use oxygen at night, but the Inogen At Home has made it easy. It is significantly smaller than the rental machine that I rented and it is quieter. I put the unit in my walk-in closet and partially closed the door. I ran a hose under the door to my bed and now the noise is hardly noticable. I have used it for a year with no problems. I have not yet had to change the cartridges.

Review by Marc

The unit is designed with a slim white casing with light blue panels at the base and top; the particle filter is located at the side of the unit. The control panel features just three silver and blue buttons to operate the oxygen concentrator and the nozzle fitting to which the user fits the nasal cannula is located to the right of the panel. The branding of the Inogen at Home oxygen concentrator is subtle, with the name of the unit printed in understated lettering just above the control panel.

Reading with the Inogen at Home Concentrator

Size and Power

Dimensions: 13" Wide x 7" Deep x 16.5" High
Weight: 18 pounds
Power: AC power supply, 100-240V, 275W, 50-60Hz (100W on flow setting 2)

The Inogen at Home oxygen concentrator is made for patients who require 24/7 oxygen in their homes, meaning that it remains in one location. However, because the unit is so lightweight, it can be easily moved by the user anywhere there is a power outlet. Additionally, the concentrator contains automatic sensors to allow for worldwide usage, allowing you to use the stationary oxygen concentrator in any country. Because the unit consumes far less power than larger machines, it can save you far more in electricity costs — up to $300 per year.

Controls and Care

The control panel, located at the top for easy access, features just three buttons to control the entire unit: the on/off button and two flow setting control buttons. Flow settings range from one to five liters per minute; the current setting will be displayed on the display screen. Once the selected oxygen flow rate is achieved — generally about five minutes after the unit is powered on — a green LED next to the flow setting numbers will illuminate.

Two other indicators; the blue indicator light, and the general caution indicator are located directly next to the on/off button. The blue light indicates that the unit requires maintenance within 30 days, while the caution indicator will illuminate in yellow, accompanied by a double beep, to show various alerts, such as low oxygen or flow or a sensor failure. A flashing light accompanied by a triple beep will alert users to an issue that must be immediately fixed.

The Inogen at Home oxygen concentrator requires minimal maintenance. Users should wipe the unit down with a cloth dampened with water and mild liquid detergent; as weekly cleaning of the particle filter is also required to ensure the unit operates as it should. The filter can be easily removed from the side of the unit and cleaned with mild soap and water; make sure the filter has completely dried before placing it back inside.

Glad I bought it!

I live at 9800 feet and use the Inogen At Home for night-time oxygen. I love the small size. I has been 100% reliable for over a year and a half. I haven’t changed the cylinders yet, but the machine was designed for self service. I put it in a walk-in closet and drilled a hole in the wall to the bedroom. Works great.

    For how long can I use my inogen one with the power outlet instead of the battery? Thank you!

      Hello Veronica, If you Inogen is plugged into a power outlet it can be used all day. But you should look to your doctor's prescription as to how long you are instructed to use it.
