The DeVilbiss 5 Liter Home Oxygen Concentrator (525DS) is one of the best-selling and most trusted 5 LPM home oxygen concentrators available — assembled in the USA and built for the demands of long-term continuous daily use. Patented Turn-Down Technology automatically reduces system pressure at lower flow settings, cutting compressor load by 15% or more, lowering power consumption, and extending the operational life of key internal components. For patients running their concentrator continuously at lower prescribed flow rates, Turn-Down Technology delivers meaningful savings on electricity costs over time.

The built-in OSD (Oxygen Sensing Device) continuously monitors oxygen purity output and triggers a visual and audible alarm if concentration drops below safe levels — providing ongoing reassurance for patients and caregivers throughout every hour of use. Delivers 87%–93% oxygen concentration from 0.5 to 5 LPM with a lockable flow meter to prevent accidental adjustment. Operates at 48 dBA. 36 lbs with rolling casters and top and side handles. Averages 310W. 3-year manufacturer's warranty. HCPCS code E1390.

Made in USA. Turn-Down Technology. OSD Standard. 3-Year Warranty.

Turn-Down Technology · Lower Power · Extended Component Life Patented Turn-Down Technology automatically reduces system pressure when the concentrator operates at lower flow settings — cutting stress on compressor bearings and internal fittings and reducing power consumption by 15% or more at 2.5 LPM and below. This reduces wear on key components, extends the operational life of the unit, and lowers electricity costs compared to concentrators without this feature. For patients prescribed lower continuous flow rates running the unit around the clock, Turn-Down Technology makes a meaningful long-term difference.
OSD Oxygen Sensing · Continuous Purity Monitoring · 87%–93% O2 The built-in DeVilbiss OSD (Oxygen Sensing Device) continuously monitors the concentration of oxygen being delivered and activates a visual indicator light and audible alarm if output drops below safe levels. The 525DS delivers 87% to 93% oxygen concentration across its full 0.5 to 5 LPM flow range. A lockable flow meter prevents accidental adjustment of the prescribed flow rate during daily use — an important safeguard for patients who require a consistent, physician-specified delivery level.
Made in USA · Best-Selling Platform · 36 lbs · 3-Year Warranty The DeVilbiss 525DS is assembled in the USA and is one of the best-selling home oxygen concentrators in the category — a platform with a long track record of reliability in both home and clinical settings. At 36 lbs with smooth-rolling casters and top and side handles, it moves easily between rooms. Operates at 48 dBA for comfortable home use. Backed by a 3-year manufacturer's warranty for long-term confidence in daily use.

Frequently Asked Questions

Turn-Down Technology is a patented DeVilbiss feature that automatically reduces system pressure when the concentrator operates at lower flow settings — typically 2.5 LPM and below. By reducing compressor load at these settings, it cuts stress on internal components by up to 35%, lowers power consumption, and extends the life of the unit. For patients prescribed lower continuous flow rates who run their concentrator around the clock, Turn-Down Technology can reduce electricity costs and extend the time between service intervals. Call us with any questions. 866-218-0902.
The OSD (Oxygen Sensing Device) is a built-in monitor that continuously measures the concentration of oxygen being produced and delivered by the concentrator. If output drops below a safe threshold, the OSD activates both a visual indicator light and an audible alarm to alert the user and caregiver. This provides ongoing safety monitoring throughout every hour of use — not just at startup — and is included as standard on every DeVilbiss 525DS unit.
Yes. The DeVilbiss 525DS is assembled in the USA — one of very few home oxygen concentrators in the category that can make that claim. For patients and facilities who prioritize domestic manufacturing, the 525DS is the leading choice in the 5 LPM category. Call us at 866-218-0902 if you have any questions about the product before purchasing.
The McKesson 146-525DS is built on the same DeVilbiss 525DS platform and delivers identical performance. The McKesson version carries a different product number used by facilities and providers who order through McKesson's distribution network. Both units include OSD oxygen sensing and Turn-Down Technology as standard. If you are ordering for personal home use, either unit will serve you equally well. Call us at 866-218-0902 and we can help you decide which is the right choice for your situation.

Help training kitten poop
I have young kitten. It is attractive to me to use the Potty Training Tray. Kitten does not know to go to litter box initially. And they even eat cat litter. For safety, the trining tray is a good start to train their poop habit and also help a smooth transition to litter box when they get older.

Great, durable toy
Color: Blue-Red, Size: Extra Large Size 5 (9")
I’ve had this toy for a while now and my dog absolutely loves it. I frequently bring it to the dog park with us and it’s also loved by other dogs. The ball is pretty durable. My dog is not a big chewer but other dogs that play and chew on it haven’t been able to pierce it yet. The handles are sturdy and also still intact. Overall a little pricey but in my opinion worth it.
