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 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 low-maintenance 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
If you need a constant steady and reliable flow of oxygen, try 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 liters 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. This 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.
