This rear access filter protects your Philips Respironics Millennium M10 from dust and debris in the air around you. Located behind the rear access door, it slides out easily when it's time to replace it.
This is the Millennium M10's rear access filter — replaced every 2-3 years, not the washable cabinet filter (which is cleaned weekly with soap and water). If you need the washable filter, look for "Millennium M10 Cabinet Filter."
Replace this filter every 2 to 3 years. Do not wash this filter — it's designed to be replaced, not cleaned. A longer replacement interval than most concentrator filters because of where it sits in the airflow path.
How to change the filter
- Turn off and unplug your concentrator.
- Open the rear access door of the machine.
- Slide the used filter out of the concentrator and dispose of it.
- Insert the new filter in its place.
- Close the rear access door, plug in, and resume normal use.
