This intake filter protects your Philips Respironics EverFlo machine from dust and debris in the air around you. Located on the back of the unit near the top, it slides out easily when it's time to replace it.
Replace the filter every year — or sooner if your environment tends to have more airborne particles (dusty homes, pets, smokers, construction, etc.).
How to change the filter
- Turn off and unplug your concentrator.
- Locate the filter on the back of the machine, near the top.
- Slide the filter out of the concentrator.
- Insert the new filter in its place.
- Plug in and resume normal use.
