These replacement filters are ONLY compatible with Inogen One G3 systems with a FLOW SETTING range between 1-5. If your replacement filters are found on the top two of the four vents, this option is for you.

Two filters are included in each order. 

Replacement eco-friendly particle filters keep dust, pet hair, and other air-borne contaminants away from your oxygen.

The removable particle filters cover the air intake screens to filter out dust, pet hair, and other air-borne contaminants.  They are washable and reusable, making them one of the eco-friendly features of Inogen concentrators.  Users should wash and dry the filters weekly (more often in very dusty environments) to help keep the concentrator working properly.

Inogen recommends replacing the filter when it become misshapen or when the screen is damaged.  Replacement filters for the G3 portable concentrators are sold in packs of two; the replacement for the At Home filter is a single, larger filter.
