LEANING AND
•
Operating the device with a dirty filter may prevent the system from working properly and may
damage the device.
•
A dirty inlet filter may cause high operating temperatures that may affect device performance.
Examine the inlet filter for integrity and cleanliness before each use. When the filter becomes dirty,
it must be replaced to ensure normal device operation.
Under normal usage, you should clean the grey foam filter at least once every two weeks and replace it with a
new filter every six months or sooner if needed.
1. If the device is operating, stop the airflow by pressing the On/Off button. Disconnect the device
from the power source.
2. Remove the filter from the enclosure by gently squeezing the filter in the center and pulling it away
from the device.
3. Examine the filter for cleanliness and integrity.
4. Wash the gray foam filter in warm water with a mild detergent. Rinse thoroughly to remove all
detergent residue. Allow the filter to air dry completely before reinstalling it. If the foam filter is torn
or damaged, replace it. (Only Respironics-supplied filters should be used as replacement filters.)
Never install a wet filter into the device. It is recommended that you clean the filter in the morning and
alternate using the two foam filters provided with the system to ensure sufficient drying time for the
cleaned filter.
5. Reinstall the filter.
