Inogen One G3 Replacement Column Pair - Oxygen Accessories - Two Removable Metal Columns - 1.63 lbs., 17.8 x 3.66 x 3.62 in.

Came on time, with easy to see/read instructions for removal of old and installing new ones. They are not a ‘generic’ brand, they are Inogen parts!

Easy to change. They work great.

I have ordered the columns 3 times to keep my Inogen portable oxygen machine working. It is a lot cheaper to spend your money on replacing the columns then to purchase another unit. I do use the unit more then before, if I leave the house it goes with me. The price is good and the cost for the columns hasn’t increased that much in the 8 years that I have had the unit.

I thought I was going to have to give up my Inogen. It was not only out of warranty, they stopped making this model. It would make loud alert noises when I tried to use it. So I went looking and found the parts and changed them out myself. Blessed relief. I have my O2 machine back. It was exactly what I needed and what I ordered. I always think thee kinds of things are expensive but it’s like $100 for the parts or at least $1500 for a new machine. Score. I am so happy. Shipping was quick, too

Easy to replace

Original replacement columns as best I can tell. Actually arrived one day early which was nice. Only problem was one of the duct caps had fallen off but i installed it anyway. It appeared to have come loose during shipping but it was a clean wrapped packaging so I felt pretty confident about it unless somebody can say don't use it and give me a valid reason why not to.

My Inogen G3 only has 185 hours but is 5+ years old. Inogen suggested I replace the Columns, even though hours are low. My Lungs don't perform well enough at altitudes over 3500 feet. Blue Cross Insurance won't approve an Oxygen Concentrator. So I lucked out and bought mine at an Estate Sale for $25. The Concentrator works perfectly with new Columns and Battery. We are on a trip now with altitudes as high as 6000+ feet. My SPO2 is around 94 - 96 with Concentrator at level 3 and around 4000 to 4700 feet. I had to go level 4 above 5400 feet. I never smoked, am athletic, reasonable weight, yet my SPO2 is below 95 most of the time without the Concentrator, at 200 feet altitude, and at Home. During sleep, 50% of the time, SPO2 is 91 and below. No one knows Why? Thanks Inogen.
