Description

Caire Companion 5 ECO Oxygen Concentrator Bundle — 5 LPMThe Caire Companion 5 ECO Oxygen Concentrator Bundle is a proven, energy efficient 5 LPM stationary home oxygen concentrator built around two technologies that set it apart in the category: CAIRE's autoFLOW, which adjusts valve cycle timing based on flow rate to reduce compressor load by 25% at 2 LPM and cut power consumption to just 250W at that setting, and ultraSILENT, which reduces noise to just 40 dBA at 2 LPM one of the quietest home

The Caire Companion 5 ECO Oxygen Concentrator Bundle is a proven, energy-efficient 5 LPM stationary home oxygen concentrator built around two technologies that set it apart in the category: CAIRE's autoFLOW™, which adjusts valve cycle timing based on flow rate to reduce compressor load by 25% at 2 LPM and cut power consumption to just 250W at that setting, and ultraSILENT™, which reduces noise to just 40 dBA at 2 LPM — one of the quietest home concentrators available. Both technologies work together to lower your energy bill, reduce wear on internal components, and extend the working life of the unit.

The ECO bundle includes the Companion 5 concentrator with OCSI oxygen monitoring — an alarm that activates if oxygen purity drops below 85%, providing an important safety alert for long-term users. The rotating flow control knob adjusts oxygen delivery from 0.5 to 5 LPM in 0.5 LPM increments. A large hour meter displays diagnostic alarm codes for easy troubleshooting. The humidifier bottle stand is integrated into the front panel for convenient setup. At 36 lbs with built-in casters and a top handle, the Companion 5 moves easily between rooms. Maintenance intervals are only required every two years. 3-year warranty.

autoFLOW. ultraSILENT. 40 dBA. Built for Long-Term Home Use.

autoFLOW Technology · 250W at 2 LPM · Lower Energy Bills CAIRE's autoFLOW technology adjusts valve cycle timing based on the current flow rate setting — reducing compressor load by 25% at 2 LPM, cutting power consumption to just 250W at that setting, and lowering the maximum draw to 300W at 3 LPM. This directly reduces daily electricity costs for patients running the concentrator continuously, while also lowering internal operating temperatures and reducing wear on compressor components. The result is a concentrator that costs less to run and lasts longer between service intervals.
ultraSILENT Technology · 40 dBA at 2 LPM · Bedroom-Friendly CAIRE's ultraSILENT technology combines a two-chamber intake muffler and a purge muffler to reduce both air intake noise and exhaust noise to just 40 dBA at 2 LPM — quieter than most home concentrators in the category. At this level the unit operates at roughly the volume of a quiet library or the background hum of a refrigerator, making it well suited for overnight use, bedroom placement, and noise-sensitive environments where a louder unit would be disruptive.
OCSI Oxygen Monitoring · LED Alarms · Large Hour Meter The ECO bundle includes OCSI (Oxygen Concentration Status Indicator) monitoring — an alarm system that alerts the user with both a visual LED indicator and an audible alarm if oxygen purity drops below 85%. The large front-panel hour meter displays diagnostic alarm codes for straightforward troubleshooting without calling for service. Additional LED indicators cover power status and operational alarms. The robust metal cannula barb provides a secure, durable connection to oxygen tubing. Intake filter is accessible through a side filter door and requires replacement only every two years.

Frequently Asked Questions

Both are CAIRE 5 LPM stationary home concentrators. The Companion 5 ECO is CAIRE's established model — well proven in home and clinical settings, with autoFLOW and ultraSILENT technologies, a 2-year maintenance interval, and OCSI oxygen monitoring included in the ECO bundle. The IntenOxy 5 is CAIRE's newest model — lighter at 34.2 lbs vs 36 lbs, with a slightly smaller footprint. Both carry a 3-year warranty. Call us to discuss which is right for your situation. 866-218-0902.
At 2 LPM — a common flow setting — the Companion 5 ECO consumes 250 watts. Running 24 hours at an average US electricity rate of approximately $0.16 per kWh, daily cost is roughly $0.96. At higher flow settings up to the maximum 350W, daily cost rises to approximately $1.34. Actual costs will vary based on your flow rate setting and local electricity rates. The autoFLOW technology meaningfully reduces consumption at lower settings compared to concentrators without this feature.
No — like all home stationary oxygen concentrators, the Companion 5 ECO requires a continuous AC power supply to operate. It is not battery-powered. If you experience power outages or need oxygen away from home, you should have a backup oxygen source — such as portable oxygen tanks or a portable oxygen concentrator. Call us if you need help selecting a backup or portable option. 866-218-0902.
The Companion 5 ECO is a stationary home concentrator designed for use with a standard AC wall outlet. It is not designed for travel, vehicle use, or use away from a power source. If you need oxygen therapy when away from home, a portable oxygen concentrator is the appropriate solution. Browse our portable oxygen concentrators →

Weird garbage
Size: 12 Long, Color: Iced Blue Light Wash
Very strange fit, saw the reviews about weird fit but so many others said great fit so that's on me. Got them for under 10 bucks so hard to complain..... however..... Got 12 Long. They are at least a size too big but I generally do that to accommodate shrinking especially length. On what planet these would be considered long I dunno. I'm only 5'8". If you pull them up to where crotch is not sagging, barely to my ankles. Almost long enough if you want the crotch to droop several inches. Fit loose but comfortable in butt and thighs. The waist however is about 4 inches too big and gaps horribly. Almost like waist is actually wider than hips. Strange. Not skinny cut except for right at ankle. The left leg inseam is cut horribly crooked and runs down almost front of leg so altering them is not worth the trouble. They are fairly thick and do stretch, like the denim wash very much. So disappointed. So the great deal I thought I was getting was garbage . Should have know for that price they were unloading their trash

Perfect fit for 5'10
Size: 10 Long, Color: White
White jeans size 10 long fit perfectly. Im 5'10 130 pounds Always have trouble with length and overall fit. These were on sale for less than 11$! Material has some stretch, not too much. I'm going to hang to dry don't want any shrinkage. Fit is less tight than an earlier version of these jeans.

Perfect buy!
Fit Type: Regular, Size: Large, Color: White
This white denim jacket came today, and finally I bought the perfect jacket! It's actual denim, heavy but not too bulky. It fits perfectly, I bought a large, it's white not off white, and it is EXACTLY what I was looking for! I had to wait a week or two but it is definitely worth the wait! Beautiful jacket, well made and at a decent price! Thanks Amazon Essentials!

Love denim and tired of cropped jackets?
Fit Type: Oversized, Size: Large, Color: Medium Blue Vintage
I like this a lot, it was what I was looking for as far as I'm so over everything you buy these days is cropped. Cropped styles are great, but are kind of getting old for some things in my opinion. The jacket is big as far as how it fits. I am 5'8" about 180 and I wish I would have got a medium, I got a large. The large is big and roomy enough that I could even wear ear a thick hoodie under it if I wanted to. However, the length is good as what I was looking for. The upper arms are large. However, this is a great quality denim jacket. Nice and thick, sturdy material (which I wanted). It's also at a great, competitive low price even if it's not on sale. Don't believe me, go ahead and search jean jackets. You'll see a ton, but I looked too and the quality did not look as good as this and plus the other jackets were a lot more for a lot less. If you're looking for a longer jean jacket, I highly recommend this. I'd say just think seriously about sizing down 1... even maybe 2 sizes. I would have gotten an XL before I read the other reviews. They recommended to size down, and after getting my jacket I could have sized down to a medium. I'm still happy with it and this is a jacket that is stitched well and will last a very long time. As always though, that's just my 2 cents. :)

Nice quality, shape not for me
Fit Type: Oversized, Size: Medium, Color: Medium Blue Vintage
This was just too boxy for my body. Material was nice, quality jean material. Color was true to image. It was a little stiff but as you would expect with nice, new and unwashed denim.
