The Pre-Inlet Filter slides into the blue chamber on the top of the Clear Inlet Filter on all Millennium Oxygen Concentrators.

Usage Information: This is a reusable filter. For best performance it should be cleaned monthly, using mild soap and water, and left to air dry completely before re-insertion into the Clear Inlet Filter. Pre-Inlet Filters should be replaced as necessary when the foam begins to appear worn or degraded.
