    Seive Beds and Replacement Columns

    Replacement columns should be changed every 12 months to 2 years, depending on the unit, usage, and the model specifications. The columns are all simple to remove and replace and in most cases do not require any special tools.

    A sieve bed, or replacement columns is the filter inside the oxygen concentrator which separates out the nitrogen from the oxygen in the air. It's important to change the columns in your portable and home oxygen concentrators, according to the operation manual, to assure that you are always breathing only medical grade oxygen.

    We carry oxygen concentrator replacement columns for Inogen units that include the Inogen One G3 Replacement Columns (Flow Setting 1-4) , Inogen One G4 Replacement Columns, Inogen at Home 5L Replacement Columns and more.
