Sunset Foam Cabinet Intake Filter for Rhythm LM5CA Oxygen Concentrator

The cabinet filter is located on the left side of the unit. To access it, use a small screwdriver to remove the filter cover. Once the cover is off, remove the cabinet filter and wash it with warm water and mild dish soap every 1-2 weeks. Make sure the filter is completely dry before placing it back into the unit. The filter should be replaced if it becomes torn, damaged, or when the unit is being used by a new patient.
