CAIRE Companion 5 Home Oxygen Concentrator
CAIRE Companion 5 Home Oxygen Concentrator with O2 Monitor
Overview
The CAIRE Companion 5 is a compact, quiet home oxygen concentrator that delivers a steady continuous flow from 0.5 to 5 LPM. It plugs into a standard wall outlet and stays put, with a large, easy-to-read flow gauge, simple front-mounted controls, and clear alarm lights — a straightforward, low-maintenance choice for everyday home use. This model includes the built-in oxygen monitor (OCSI), which continuously checks oxygen purity and alarms if it drops below 85%, for added peace of mind.
CAIRE's ultraSILENT design keeps it to about 40 dBA at 2 LPM — quieter than a normal conversation and unobtrusive enough to run overnight — while autoFLOW technology keeps power draw low (under 300 watts at 3 LPM) to help hold down energy costs. At about 36 pounds it's easy to move from room to room, and an integrated stand on the front holds a humidifier bottle for drier climates or added nasal comfort.
Key Features

- ultraSILENT operation — about 40 dBA at 2 LPM, quiet enough for sleep.
- autoFLOW technology for energy efficiency — under 300 watts at 3 LPM.
- Simple, easy-to-read controls, a large flow gauge, and clear alarm lights.
- Alarms for power failure, high and low flow, general malfunction, and low oxygen.
- Integrated humidifier-bottle stand on the front (humidifier sold separately).
- Compact and lightweight at about 36 pounds; low maintenance (every 2 years).
- 3-year warranty on the concentrator.
This is a stationary home unit — it plugs into the wall and delivers continuous flow, which is the type of delivery many home setups call for, including steady overnight use. That's different from the lightweight portable concentrators, which are mostly pulse-dose for travel; many people use a stationary unit at home and a portable one for going out. The standout on this particular model is the built-in oxygen monitor, which continuously checks purity and alarms below 85% — a reassurance feature the base model doesn't include. It's quiet and efficient enough to run overnight without disrupting sleep or spiking the power bill, and it pairs with a humidifier bottle (sold separately) for drier climates.

Is this portable?
No — it's a stationary home unit (about 36 lbs) that plugs into a wall outlet for steady, continuous use. It's light enough to move from room to room, but for travel and time away from home a portable oxygen concentrator is the better fit.
What does the oxygen monitor do?
This model includes a built-in oxygen monitor that continuously checks the oxygen purity and sounds an alarm if it drops below 85%, so you'll know right away if the output isn't at spec. It's the main feature that sets this version apart from the base Companion 5.
Do I need a humidifier?
It's optional. There's an integrated stand on the front of the unit for a humidifier bottle (sold separately), which can help in drier climates or for added nasal comfort during longer use.
