6.2 Cleaning and Replacing the Air Inlet Filter
Under normal usage, you should clean the gray foam lter at least once every two weeks and
replace it with a new one every six months. The white ultra-ne lter is disposable and should be
replaced after 30 nights of use or sooner if it appears dirty. DO NOT clean the ultra-ne lter.
1. If the device is operating, stop the airow. Disconnect the device from the power source.
2. Remove the lter(s) from the enclosure by gently squeezing the lter in the center and pulling
it away from the device.
3. Examine the lter(s) for cleanliness and integrity.
4. Wash the gray foam lter in warm water with a mild detergent. Rinse thoroughly to remove all
detergent residue.
5. Allow the lter to air dry completely before reinstalling it. If the foam lter is torn or damaged,
replace it. Only Philips Respironics-supplied lters should be used as replacement lters.
6. If the white ultra-ne lter is dirty or torn, replace it.
7. Reinstall the lters, inserting the white ultra-ne lter rst if applicable.
