Easy Usage I enjoy my G4 and the freedom it gives me. I’m 93 years old and find it easy to operate. The questions I have asked of customer support have all been always been answered and the representatives have been courteous. Thank You.

Erica was more than helpful Erica was more than helpful. I appreciated her so much. The Inogen system has given me so much freedom. I love it♥️

the sales guy was great but i bought… the sales guy was great but i bought too soon. hit the road so it was a month before i could try it. easy set up. but no one told me that the system has a 5-6 sec cadence of a repetitive 'pop'. Super annoying. sales support good. follow up good. gatekeeper answering service is an idiot who kept me from buying for almost a month.

I love the convenience on how portable… I love the convenience on how portable the unit is. The quietness of operation and the concentrator is great also. The only complaint I have is the cannula attachment kinking. I wish there was a spring that would support the tubing where it attaches. I’ve mentioned this to Inogen, but was told they have had numerous concerns. Robert Oliveri

This was the best company I have ever… This was the best company I have ever dealt with! My previous oxygen provider ignored three prescriptions for a portable oxygen concentrator from two pulmonologists. The Inogen team handled all of the insurance requirements. They are now my provider for all oxygen needs. The portable unit is simple and functions perfectly for my needs. Thank you to everyone at Inogen for the great experience.
