Does anyone know where you can buy the columns for the G2 model?

G2 sieve beds are not user exchangeable

Yes, for the inogen 3. Make certain that this is the correct filter for your machine as there are two types of inogen 3’s.

I bought the inogen oxygo G3 concentrator (new 2 years ago) Will these work for that unit? Thanks!

If it's the 1 to 5 liter unit, it should. My unit is known as the inogen G3.

Reliable and worth the money

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.

2nd purchase satisfaction!

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!
