“When I was on tanks, I felt imprisoned. Now that I’ve got my Inogen One, my life is full again. With this little device, I can go anywhere and do the things I love.”§
— Len B.
Finally, oxygen delivery reimagined. No tanks required! Our light weight, easy-to-use stationary and portable oxygen concentrators help you move about your home—and out and about in the world!
"I was born on the 4th of July so freedom is a big deal! So to be tethered to an oxygen machine was not my favorite thing. But the Inogen One is very easy to operate and you barely notice it's there.”§
— Claudia H.
I am very satisfied with my portable and plug in concentrators. The portable allows me to continue to do the work I enjoy, go on walks, and light exercise. The plug in is quiet and so light weight. It easily travels with me to visit family and go on fun trips with my husband. I am so thankful!
This is the best oxygen concentrator I could have ever bought. When I called them the rep rook care of everything, from explaining any questions that I had, to getting the script from the doctor. Now I can go anywhere and always have my oxygen with me.
It’s much lighter weight than the canisters and gives me hours more freedom to do the things I want to do. Love the charging options and being able to track everything on my iPhone. Wish I’d made the purchase sooner!
