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.

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.

Portable size to freshen up
Scent: 555 Strawberry + Aire, Size: 1 Fl Oz (Pack of 1)
The fragrance is fruity and light. This is a great size to pop in a purse or gym bag. I also found it easily in my bag because of the bright red color, and my bag is ALWAYS a mess lol. The lid stays on with no issues. Since this is a mist , the scent is there and gone pretty quickly. It doesn’t last long. The price is decent for this brand, but it isn’t going to perform much differently than what you get at the “blue gingham” place. I’ve ordered from Lake & Skye before and I generally like their products.

Fruity body mist
Scent: 555 Strawberry + Aire, Size: 1 Fl Oz (Pack of 1), Scent: 555 Strawberry + Aire, Size: 1 Fl Oz (Pack of 1)
This is a great little travel-size body spray to keep in a beach bag, purse, or suitcase. The spray bottle is compact but still feels sturdy, and it’s super convenient for on-the-go use. The scent is pleasant, sweet, and fruity, and not overpowering at all. To me it has a warm fruity vibe that kind of reminds me of summer days as a kid eating popsicles. Nice for everyday wear if you want something light and easy, plan to reapply every 3 hours or so for maximum scent.

Good quality and definitely worth it for energetic dogs.
Color: Orange
The automatic moving and rolling action really grabs my dog’s attention, and the rope adds extra fun for chasing and playing. It helps reduce boredom and keeps my dog mentally stimulated, especially when indoors. The motion activation works well, and it’s a fun and engaging toy overall.

my dogs love it
Color: Orange
This interactive toy has been a lifesaver for keeping my furry friend occupied. It moves around in unpredictable ways, which really keeps him engaged and guessing. The rope attachment is a nice touch, allowing for a bit of tug-of-war when he's feeling energetic. It's durable enough to withstand his enthusiastic play, which is a huge plus. I've noticed he's less anxious and destructive when I'm not home since he has this to play with. Definitely a great purchase for any dog owner looking to provide some mental stimulation.

How many dog toys have you bought that just laid on the floor unused?
Color: Orange
New husky has more energy than an entire pre-school - even being walked more than three miles a day wasn’t sufficient to drain her excess energy. I threw the dice on this - and it’s AWESOME. Comes with an extra rope and an extra side piece. Rechargeable with a USB-C cable. When you turn it on, the blue LEDs flash, the entire device buzzes, bounces, and races back and forth across the floor. After a couple of days of uncertainty, my new husky LOVES this. She chases it around, grabs it by the attached rope and carries it from room to room. After a short bit of activity, the toy goes into ‘sleep’ mode, until either the dog touches it again or a timer has elapsed, and then it fires up and starts buzzing and racing around the floor again. From a full charge, the toy will keep your dog entertained all day. Bright orange color makes it much easier to find when it’s rolled behind the toilet (as it did this afternoon). Sturdy. Highly resistant to chew damage. If this one wears out or breaks, I’ll absolutely get another one.
