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.
