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 →

Fun read
Format: Kindle
I'm not really into mafia books but I love Roxy Collin's other series so I decided to give it a try. It had the same great romance, spice, swoon-worthy characters and exciting plot that are her signature. Arben was my favorite, although it was a bit sudden how quickly he changed from ignoring her to wanting to be pack. There were almost too many twists/layers of lies to keep track of but I'm looking forward to reading the other books. The only thing that detracted from the story for me was the need for a bit more proofreading. It was mentioned that Kelly is a female and male at different points, leading me to think she changed her mind at some point about the character's gender but didn't go back and edit it to align in all places. Like another reviewer pointed out, step siblings are different than half siblings. They are incorrectly referred to as step siblings because they (allegedly) share the same biological dad. There are a few other typos as well but those aren't a big deal.

Stepbrothers, Secrets, and Sizzling Heat
Format: Kindle
Twisted Lies by Roxy Collins is a wild ride through family secrets, amnesia, and a steamy stepbrother romance. When Kelly discovers her life is built on lies, she ends up tangled with three alpha stepbrothers and an assassin who once helped her through a heat. The tension? Off the charts! The heat is real, and the complications are messy in the best way. Full of twists, secrets, and fated mates? You'll be hooked from page one! Love omegaverse drama with a dash of taboo? This one's for you!

Good read
Format: Kindle
The book has some good twists and turns, but truthfully I was so confused on some things. It didn't have a good flow for me personally. Not sure if it's due to typos or using him/her wrongly, but I thought Kelly was both a guy and a girl. Actually I still don't know, and it made me incredibly frustrated. It would refer to Kelley as him or he, and then again in another part of the story as her she and sister. On to the next book, I hope there is some clarity and a smoother flow. This is a slow burn, and I just don't know how much I care for the Alphas yet. Idk if I recommend.

This is a story we’re a omega has been lied to by her mother and finds out that someone is slowing dieing. 3 alpha take the omega and feed her more lies so they can use her against her father so they can find their mate Kelly. This is a dark read and ends in a cliffhanger and so good.
