The Air Inlet Filter slides into the side of the concentrator as shown. Filters should be replaced as necessary when they begins to appear worn or degraded. The OxLife Independence should never be used without an Air Inlet Filter in place.

Usage & Cleaning: For best performance the Air Inlet Filter should be washed weekly, using mild soap and water, and left to air dry completely before re-inserting into the machine. (Keep a spare filter on hand so that you can have one in the machine while the other is being cleaned.) See your OxLife manual for complete instructions.
