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 →

Cheap
Size: 6FT*6FT, Color: Black
They serve their purpose as long as you leve them in one place and not moving them around and they're kinda flimsy and some of the velcros are cut too short and can't stay closed

Excellent separation screen
Color: Dark Black
Easy to put together. A drill with the hex head made it easier. I see some of the photos in the reviews and it looks like the fabric is wrinkled and loose. However, when we put it together, the fabric was tight and it looked polished. Using this divider to separate a recording space from the rest of the room the overall look is nice. I would not use this in a living room, but it’s fine in another room. Once put together, it is pretty sturdy. The pieces that connect the panels together are plastic. We did fold it one time when we moved it and didn’t have any issues, but it is going to remain stationary so I can’t comment on folding it more than the one time. It is very lightweight and very opaque.

JUNK!
Color: Grey
This is the worst product in every way. I ordered a similar one previously and thought I was getting the same product which was great, no this is a piece of junk. I would have gladly sent it back but I needed it. I feel sorry for anyone who tries to put this together without any mechanical ability. I have plenty and it was still a nightmare. We will surely not be purchasing anything from this company in the future. The previous one I bought was a (Kecreque Room Divider). Is is a quality product!

Nice looking and lightweight
I bought this to put in front of my basement doorway where I am missing a door. I don't like my cats in the basement and this works very well. However, because of the panels being up on 2 inch or so tiny stilts, my cats can still get through. So I have it upside down and will be putting gliders on the "bottom" of each panel. Note that it did come with gliders on the little stilts.
