Caire Companion 5 Home Oxygen Concentrator

Cost Efficient & Low Maintenance 

The Companion 5 is low-maintenance and easy to use. It boasts energy efficiency as a key feature and is also extremely economical compared to most other units. It draws only 250 Watts at 2 LPM because of its autoFlow Technology. It doesn't use over 350 watts of electricity, even on the highest oxygen setting. The Companion 5 gives its users significant savings on their electrical bills and helps decrease wear on electrical components. The Companion 5 Concentrator only requires maintenance every 2 years. The intake filter can be easily changed by yourself through a handy filter door.

Continuous Flow

When you need a constant and reliable flow of oxygen you need CAIRE’s continuous flow technology. Set your device to the liter by minute prescribed by your doctor and rest assured that you are receiving an uninterrupted stream of oxygen. The Companion 5 Concentrator offers continuous flow oxygen at 87% to 95.5% concentration and up to 5 liter per minute. The variation of purity can depend on the elevation and the setting the concentrator is on. The oxygen flow settings run from 0.5 to 5 LPM, in 0.5 increments. It is a perfect stationary concentrator for users who need a half-LPM dosage of continuous flow. 


The noise level of the Companion 5 is one of the lowest at only 40 decibels which is no louder than the hum of a home refrigerator. This makes it perfect for use during sleep and other activities where silence is necessary.

Q: is there a 110v/220v power option available (Asked on 05/18/2022)
I'm sorry, we do not have a 110v/220v power option. You will need a transformer and I recommend reaching out to a battery center/hardware store for expert advice on exactly what type of transformer to use.
Q: Machine is showing an error code of AL P08 with flashing yellow light. What is problem? (Asked on 03/31/2022)
That alarm is low oxygen concentration <85%. Make sure you filters have been changed and if they have you may need to have it repaired.
Q: Hello,

I am shipping a Caire Inc Companion 5 and need to know if there are any batteries within the unit?

john (Asked on 05/07/2021)
There does not appear to be any batteries within the unit as I can see in the manual. This is a unit that needs to be plugged directly into a wall unit.
