There are a number of medical conditions that require a person receive supplemental oxygen. An oxygen concentrator is a cost effective way to provide this needed treatment!

An oxygen concentrator uses a clever method to remove nitrogen from the air and produce concentrated oxygen at levels up to 95 percent. (For reference, room air contains 78 percent nitrogen and 21 percent oxygen.  The oxygen concentrator uses two sieve beds to trap and pull out the nitrogen!)

A doctor decides how much oxygen a person needs and will write a prescription to purchase or rent an oxygen concentrator.

4. Drive Medical DeVilbiss 10L Oxygen Concentrator


Built upon the reliable features of the popular 525 concentrator, the Drive Medical DeVilbiss 10L Oxygen Concentrator delivers optimal oxygen delivery for patients requiring higher concentrations of oxygen. This innovative machine has a high capacity and a wide range of useful features.

Substantially smaller in size than other high-capacity concentrators on the market, the flame-retardant DeVilbiss weighs only 42 pounds and comes in the same shell as the 5-liter size, yet is still compatible with cylinder transfill systems. It delivers 87% to 96% of oxygen purity ranging from 2 to 10 LPM, resulting in adaptive use for an array of patients with varying needs, from home use to hospitals and long-term care facilities. 

Standard on every unit, the exclusive DeVilbiss Oxygen Sensing Device (OSD) system ensures dependable performance and patient safety with real-time monitoring of the oxygen produced. Easily accessible patient controls and bright LEDs make operation a breeze, and a front-located knob facilitates simple air-flow adjustments with its flow meter positioned directly below to verify setting selections. 

This oxygen concentrator integrates several safety alarms to further ensure proper operation of the device, and these alarms will sound when there is high pressure, low oxygen, high gas temperature, low-high flow, when the power goes out, and if service is required. 

Its cleverly-designed recessed humidifier nook and protected cannula port guard against accidental damage. Convenient handles on the top and side enable easy portability for rolling or carrying. 

Features and Benefits 

  • 10-liter capacity for users requiring higher oxygen concentration levels  
  • Adjusts from 2-10 LPM for multiple patient usages

Customer Feedback

Most of the positive feedback regarding the Drive Medical DeVilbiss 10L Oxygen Concentrator comes from long-term care facility professionals who often use the device for different patients, or who cater to patients with varying oxygen flow level requirements. Because it is so easy to adjust to deliver anywhere from 2-10 LPM, it provides just the right flow for every user.

Home users who need a higher capacity machine very much appreciate how small this 10-liter oxygen concentrator is designed, and find it very easy to move it around with its rolling wheels and top and side handles.

Another loved feature talked about by both healthcare professionals and the patients themselves is the real-time monitoring provided with the Oxygen Sensing Device system, which alerts users to any potential problems, along with built-in alarms for various issues, such as loss of power and low oxygen flow. 

The only negative feedback associated with this concentrator includes its noise level and its power consumption. Ranging from less than 59 to 69 dBA, this may be too loud for some users, especially when using it at night to sleep. Its power consumption is listed at an average of 120VAC, 60Hz, 639W, and some users said their power bills went up significantly after using this concentrator. 


  • High 10-liter capacity

  • Variable flow rates from 2-10 LPM 

  • Small, compact size for a machine of its class

  • Real-time monitoring with OSD system

A humidifier bottle can be placed in an adaptor located on the front of the machine. A built-in molded top handle enables users to roll the concentrator easily. 

The neutral colored concentrator weighs 54 pounds and delivers oxygen at 2-10 LPM. It provides oxygen concentrations between 87 - 94%.

The Inogen’s simplistic control panel makes it easy to operate for just about any patient, and it’s also easy to maintain by just cleaning the surface and the particle filter, along with replacing the included cannula, at periodic intervals.
