Depending on your specific needs. Home oxygen concentrators can only be used when connected to a power line at home. However, home oxygen concentrators have a higher flow rate and less noise. Portable oxygen concentrators are battery-powered and can be used at home, in a car, or on the go. They have a lower flow rate than home oxygen concentrators, but are lighter and smaller.

A continuous flow oxygen concentrator provides a steady supply of oxygen at all times. On the other hand, a pulse flow oxygen concentrator delivers oxygen only when you breathe in, as it usually has a breathing sensor that activates the flow based on your breathing pattern.
