Installing/replacing the air lters
Caution: A properly installed, undamaged Philips Respironics reusable pollen lter
is required for proper operation.
The device uses a grey reusable pollen lter that can be rinsed and a blue disposable ultra-
ne lter. The reusable lter screens out normal household dust and pollens, while the ultra-
ne lter provides more complete ltration of very ne particles. The reusable lter must be in
place at all times when the device is operating. The ultra-ne lter is recommended for people
who are sensitive to tobacco smoke or other small particles.
The grey reusable lter is supplied with the device. A disposable blue ultra-ne lter may
also be included. If a lter is not installed when you receive your device, you must at least
install the reusable lter before using the device.
1. Remove the humidier water tank from the device. See the “Removing the humidier
water tank” section later in this manual.
