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 →

Pretty Darn Good
Format: Kindle
So I’ve been on a omega kick and this definitely hit the spot. Madison was frustrating at times with how she acted towards Lucas, Gray, and Rian. It was like she said towards the end, she didn’t believe she deserved nice things. It would have been nice to hear from her best friends again. They kind of were there in the beginning and the gone except for mention of text messages received from them. I feel like her friends would have been great help in encouraging Madison to go with the pack and never give Brent another chance because he was toxic. I loved Rian. His personality was awesome. His humor. His ability to make Madison comfortable whenever she was feeling overwhelmed. And the fact he fell for her and she fell for him first. They are cute together. I do feel like Lucas was the odd man out though. Like Lucas didn’t develop as much of a relationship with Madison. I would have really liked to see more development in the relationship between them. It was also the same with him and Rian. There is really no relationship displayed. Most of the relationship being displayed is between Rian and Gray. Nevertheless, I loved reading about the dynamic that came to fruition during the entirety of this story. Madison finally got her happiness. And Brent finally got punched in the face. Everyone got exactly what they deserve.

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know. PRO: * Very likable characters * Lots of steamy scenes that are written very well * The spelling and grammar are good * The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens. CON: * Almost no interactions with any characters outside of Madison and the pack * Nearly no plot. They meet, get together for a heat, agree to make it permanent, done * Quite a few typos such as extraneous words, missing words and words out of order THINGS TO KNOW: * More steamy scenes than storytelling * A lot of MM & MMM, some MFMM during heat

Fluffy and Nice Omegaverse
Format: Kindle
… this would have made 5 stars but for 2 reasons. A.) there were quite a few typos; misspelled words, missing quotations, “the his” mistakes, and various signs that maybe a proofread would do good. B.) the writing was quite textbook. Late blooming omega is struggling with her new self, finds a absurdly wealthy pack of alphas, every thing is almost insta-love but she resists, then decides to love herself and let everyone be happy. Rian was my favourite (obviously the author’s favourite too because he got the most page time) but I wish we could see more of his CEO side? He went to work maybe ONCE the entire time. Gray was supposed to be the “growly one” but he turned out to be puppy dog. Lucas was a genius brainiac doctor - but also super alpha with an aggressive hindbrain with a breeding k*nk?? And then there was no actual “breeding”?? Spice 3/5 - normally omegaverse books are super high on messy smut but this was tamer. Romance 3/5 - insta-love that was then resisted because of personal hangup’s Plot 2/5 - weird paced head hopping, showing the same scene from different POV’s that made me feel like it was 2 steps backward, 1 step forward. Humour 4/5 - there were a dozen lines that genuinely made me chuckle out loud Would have been five stars but the lack of proofreading and the predictable plot made me unable to get up to ADORED IT level - four stars is still and official ENJOYED IT, y’all. This isn’t a bad rating. The “Club Heat” has intriguing possibilities so I’m going to give the second one a shot.
