Technology Comparison

Innovation in power consumption has allowed Inogen At Home to consume the least amount of electricity when in constant usage. When set to the Flow Setting of 2, it uses the same amount of energy as a 100W light bulb. When compared to traditional Home Oxygen Concentrators, the Inogen At Home may even save you money on power. 


The Inogen At Home also features a series of smart alarms to help keep the user informed of oxygen therapy operations and issues that might arise. Three priority alarms allow users to stay notified of changing status in their therapy without tech knowledge.  

DeVilbiss 5L Oxygen Concentrator 

The DeVilbiss 525 comes equipped with unique Turn Down technology, meaning that the concentrator is constantly monitoring oxygen output. If the flow rate is set to 2.5 LPM or less, the unit will consume less power. This could mean potential energy savings for the user, as well as an extended machine life for the DeVilbiss. The stress on the internal fittings and compressor bearings is lessened by reducing the system pressure by as much as 35% because the device automatically turn-down its flow cycle below 2.5 LPM. The patented turn down technology also improves the performance of the device by reducing the wear on internal components which extends the life of the concentrator. 

Size And Weight Comparison

Inogen At Home Oxygen Concentrator is portable and easy to transport from room to room, making at-home oxygen consumption more convenient. By reducing the size, engineers at Inogen were able to make the oxygen concentrator less bulky. With a lightweight design, elderly patients especially will find the Inogen At Home easier to maneuver from one room of their house to the next. The smaller design also allows the Inogen to stay discreetly out of the way of normal household life.

While slightly larger in size and weight, the DeVilbiss 5L still provides a lightweight unit that can be easily toted around the house. The handle at the top is easy to grasp so most people will find it easy to move the oxygen concentrator as needed. The compact cabinet stays out of the way and provides easy access without being bulky for users who want to draw attention away from medical equipment in their home.  

Noise Level Comparison

Inogen At Home Oxygen Concentrator

Oxygen users often complain that their stationary oxygen concentrators disrupt the sleep of others  during oxygen therapy.  The Inogen At Home Oxygen Concentrator allows users AND their sleeping partners to enjoy the oxygen therapy experience without any sleep disruption. The Inogen One Home Oxygen Concentrator typically reaches up to 40 decibels at the setting of 2. 


Quieter operation also means that daytime use allows users to watch TV or listen to music or have conversations without the disruptive noise of their oxygen concentrator.  

DeVilbiss 5L Oxygen Concentrator

The updated cooling process and improvement in quality reduce the noise level so that it is only 15% of a typical home concentrator’s sound. The Compact 525DS oxygen concentrator comes with proven turn-down technology, patented by DeVilbiss, which is meant to decrease the wear on the internal components and improve the life of the device. This patient-friendly device requires no maintenance during the first two years. 

Oxygen Flow Settings and Output Comparison 

Inogen At Home Oxygen Concentrator

The Inogen At Home oxygen concentrator offers up to five flow settings for oxygen therapy. Increased flow settings also increases power usage. These flow settings equal to about 1-5 liters of pure oxygen per minute. This flow range is about average for most stationary and portable oxygen concentrators and should meet the needs of most respiratory oxygen therapy prescriptions.  


In some instances, higher levels of oxygen flow may be required for some very severe respiratory illnesses. Check with your doctor about your oxygen therapy prescription.  

DeVilbiss 5L Oxygen Concentrator

The DeVilbiss 5L delivers the standard range of 1 to 5 liters per minute of pure oxygen. In this way, it is the same in terms of oxygen output as the Inogen At Home. A user trying to make a choice between these two oxygen concentrators, will realize that they are about the same in terms of oxygen output. Both machines offer different benefits and features that may be important beyond LPM for a user.
