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.

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.

Tropical Fringe Fun for My Summer Outfits
Color: Natural, Color: Natural
I am absolutely obsessed with this straw purse because it feels like a vacation in my hand. The first thing I noticed is how the raffia fringe has this playful half moon shape that looks like a little lion mane but in a very high fashion way. My daughter even joked that it looks like a giant fancy taco which makes it such a fun and unique piece to carry around. It is incredibly lightweight which is a huge relief because I do not want to carry a heavy bag when the weather is hot. Even though it looks compact on my mannequin, it is surprisingly roomy inside and fits my phone and all my daily essentials without feeling stuffed. The magnetic closure is quite strong so I do not have to worry about my things falling out while I am walking around a summer party or a night out.
The neutral tan and cream colors in the fringe make it very easy to match with almost any outfit I own. I really appreciate the small metal brand patch on the front because it gives the bag a more polished and expensive look than a typical straw tote you might find at a souvenir shop. One thing to keep in mind is that the raffia is very textured so you should probably be careful with delicate silk fabrics so it does not snag. It feels very sturdy and well made for something that is woven from grass and I love how the fringe adds so much movement when I am moving around. This bag is definitely going to be my go to accessory for the rest of the season because it is both stylish and very practical for my needs.

👜 Effortless Spring-to-Summer Clutch That Feels One-of-a-Kind

👜 Effortless Spring-to-Summer Clutch That Feels One-of-a-Kind
I’ve been a longtime fan of Sam Edelman, especially because they actually make stylish pieces that work for real life. So when I saw this clutch, I had a feeling it would be good… but I didn’t expect it to hit *this* level.
This bag is a vibe. The raffia texture and that half-moon fringe give it such a unique, standout look without trying too hard. It feels like the perfect piece to roll right into spring and carry straight through summer. Think beach days, dinners out, travel nights, all of it.
What I love most is that it doesn’t look like everything else out there. It feels original, like you found something special instead of just grabbing another basic clutch. It’s lightweight, easy to carry, and the magnetic closure keeps things simple and secure.
It also pairs effortlessly with different outfits. You can dress it up or keep it casual and it still works.
Now let’s be real, it’s a designer piece, so it’s not cheap. But for the style, quality, and uniqueness, I do think it delivers strong value for money.
Five stars from me. This one’s coming with me everywhere this season ☀️

Super cute clutch!
Color: Natural
This is a beautiful clutch. I got the “Natural” color, and the tones are definitely subtle. I am already eyeing the Spicy one too, but for me, the natural color is just easier to match with outfits. I did laugh though because my nephew said it looks like a taco, but honestly that just makes me love it even more!
The material is extremely nice, it feels very premium and well made. I was a bit nervous because I have had cheaper bags with that shredded-style material that flakes and falls apart, but that is not the case here. It feels really well made. I cannot speak for long-term durability yet, but so far there is no shedding or anything like that. I also did not notice any loose stitching or threads at all, it just feels like a high-quality bag.
It has small magnets to keep it closed, which work nicely. There is not a ton of space since it is a clutch, but there is still enough room for my phone and a few small items, so it works well.
Overall, it is just a really gorgeous, well made bag, and I really do not have anything to complain about.

Lily Clutch - awkward size and fabric.
Color: Spicy, Color: Spicy
The Sam Edelman Lily Clutch handbag is a bit awkward, in my opinion. I've been told that it looks like a taco and like a folded up rug, and it does look rather awkward. It's also much larger and bulkier than I was expecting. I can't even find a comfortable or natural way to hold it. I don't love how it bulges out on the sides or the way it's difficult to grip because of the fabric design.
It's eye catching and a good conversation piece, but it feels impractical. It's more of a statement piece than a useful every day bag or something I'd want to take on a long outing.
It looks interesting, but it isn't a bag that makes my life easier or more compact.

Great boho clutch with lots of interest and texture, but bag itself is small, materials are fragile
Color: Spicy, Color: Spicy
This Sam Edelman Lily Clutch Handbag would be great for a beach vacation or summer getaway. It is very lightweight and almost has a fan-like appearance making it perfect for a hot Summer evening out. I ordered the 'spicy' red and natural color combo, and it looks just like in the product photos. The purse itself excluding the raffia fringe is pretty small and thin, and it does feel a bit fragile. You might be able to fit your phone, a card holder, and a lipstick in there, but that is about it. It is not lined on the inside so it is a touch see through. The magnetic closure is a nice touch and works well, and there is a brown faux leather logo on the outside. It also comes with a dustbag to store it in, which you will want to use since the raffia will easily collect dust and break off easily over time. I do understand that this is a name brand premium item, but it does feel a bit pricey given the overall quality of the materials. I would recommend this if it went on sale at a significant discount.
