Features and Benefits of DeVilbiss 525DS Oxygen Concentrator

  • The DeVilbiss 525DS includes a OSD® (Oxygen Sensing Device) for patient's safety and also the device's reliability to increase the time between each service interval.
  • Secondly, the recessed humidifier nook helps protect the humidifier bottle and prevent damage.
  • Additionally, the unit is compatible with oxygen tubing of up to 50 ft and cannula of up to 7 ft or 15.3 meters allowing for more freedom of movement for users.
  • Also, the easily accessible top and side handles make the unit simple to move around.
  • The DeVilbiss SmartTrack Concentrator Management System downloads critical equipment information, so your oxygen concentrator is always running at peak performance. 


The DeVilbiss 525DS is low maintenance and can be used by anyone. The air filter and connector should be cleaned at least once a week. Clean the concentrator exterior cabinet weekly by using a damp cloth and then wiping dry. In addition to the concentrator, clean and replace the cannula/mask, tubing, and humidifier bottle according to the manufacturer’s instructions.

Noise Level

The DeVilbiss 525DS provides a quiet operation compared to many other oxygen concentrators, so you can conduct oxygen therapy while watching TV or having a conversation with friends. At only 48 dBa, this oxygen concentrator can be used without disrupting your day, thus making oxygen therapy more tolerable and more peaceful.

Flow Setting

The DeVilbiss 525DS provides continuous flow settings up to 5 liters of oxygen per minute (LPM). Continuous flow oxygen delivers flow without interruption from the cannula and only stops when the concentrator is turned off. This continuous flow feature ensures the same amount of oxygen through the cannula regardless of the patients' breathing patterns. Therefore, this type of oxygen delivery allows the flow rate to be measured at a constant volume.

Oxygen Purity Level

Oxygen purity is very important for maintaining healthy oxygen therapy. Medical grade oxygen for an oxygen concentrator should be no less than 90.0% and no more than 96.0%. It’s also important to consider your altitude level when looking at ideal oxygen saturation levels. Therefore, the DeVilbiss 525DS provides 87% - 96% at all flow rates.

Ease of Use

The easy-to-use control panel is ideal for anyone who is not tech-savvy, including older individuals or someone just beginning oxygen therapy for the first time. Intuitive alerts also keep users up to date on operations. Moreover, with minimized complex controls and a streamlined design, the DeVilbiss 525DS can provide a frustration-free performance. 

DeVilbiss 525DS Stationery Design 

The minimal design features of the DeVilbiss 525DS compared to other oxygen concentrators provide a compact, lightweight unit that can be easily moved from room to room. Therefore, people who live active lifestyles can still go about their days doing their normal activities around the house.
