Hi I have an INOGEN G3 portable oxygen concentrator, which is 1-4lpm pulse mode, I have been advised by my oxygen consultant that I need to increase my oxygen levels and buy a machine up to 6lpm per minute.
So I have a INOGEN G3 for sale it is 18 months old, has battery, Mains charger and car charger...I know new is in excess of £2600
Open to offers many thanks Ned
