Description
The Foam Air Inlet Filter For Respironics Millennium Oxygen Concentrators is a reusable filter which replaces the Respironics OEM #H619. It measures approximately 4"W x 8"L x 1/4"H, and will fit all Respironics Millennium Oxygen Concentrators, sliding into the left side of the concentrator.
For best performance it should be vacuumed or cleaned weekly, using mild soap and water, and left to air dry completely before re-inserting into the machine. Air Inlet Filters should be replaced as necessary when the foam begins to appear worn or degraded.
