Caring for the lters
Notes
• Only Philips supplied lters should be used as replacement lters.
• Replace the disposable, ultra-ne lter if it is damaged or has accumulated debris.
Under normal usage, you should rinse the reusable lter at least once every two weeks and
replace it with a new one every six months.
The disposable, ultra-ne lter should be replaced after 30 nights of use, or sooner, if it
appears clogged. DO NOT rinse the ultra-ne lter.
1. If the device is operating, press the Therapy button to stop the airow. Unplug the power
cord from the wall outlet.
2. Remove the water tank to access the lter area, then remove the lter from the device.
Refer to the “Install/replace the air lters” section earlier in this manual.
3. Take the reusable lter to a sink and run warm tap water through the white middle
portion of the lter to rinse away any debris.
4. Shake the lter to remove as much water as possible.
5. Allow the lter to air dry completely before reinstalling it. If the lter is damaged, replace
it.
6. Reinstall the lter into the lter access area on the device.
