Installing/replacing the air filters
Caution: A properly installed, undamaged Philips Respironics reusable pollen filter
is required for proper operation.
The device uses a reusable
pollen filter that can be rinsed and a disposable ultra-fine filter.
The reusable filter screens out normal household dust and pollens, while the ultra-fine filter
provides more complete filtration of very fine particles. The reusable filter must be in place at
all times when the device is operating. The ultra-fine filter is recommended for people who are
sensitive to tobacco smoke or other small particles.
The reusable filter is supplied with the device. A disposable ultra-fine filter may also be
included. If a filter is not installed when you receive your device, you must at least install the
reusable filter before using the device.
1. Remove the humidifier water tank from the device. See the “Removing the humidifier
water tank” section later in this manual.
2. To remove an existing filter, pull the white tab on the end of the filter and pull the filter
out of the device
3. If applicable, place a dry, reusable pollen filter on top of a new, optional disposable
ultra-fine filter and firmly snap them together.
