How high can your oxygen level go on an oxygen concentrator?

The highest flow oxygen concentrators output oxygen flow at 10 liters per minute. The Respironics Millennium M10, Invacare Platinum 10, and the AirSep Intensity 10 are three home oxygen concentrator machines that deliver this highest oxygen level. These units allow safe oxygen use without the refill requirements or flammability of old-fashioned oxygen tanks.
