CarolNancy Report post Posted April 24, 2014 My husband uses oxygen 24/7. We are having problems with the VA in getting continued oxygen without having to go back to our home base in Amarillo, TX. every 6 months. We have been checking into the Inogen 3G portable oxygen concentrator that weighs only 4.5 pounds and doesn't need refills. Has anyone had any experience with the Inogen? Thanks.
