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