What to do
Rinse or replace the reusable air filter or replace the disposable
ultra-fine filter.
The temperature of the air may vary somewhat based on your
room temperature.
Make sure that the device is properly ventilated. Keep the
device away from bedding or curtains that could block the flow
of air around the device. Make sure the device is away from
direct sunlight and heating equipment.
If the problem continues, contact your home care provider.
Under most conditions, a full humidifier water tank should
last for a typical sleep session if the humidifier tank is filled
to the maximum fill line at the beginning of the sleep session.
However, many factors impact water consumption, including:
your humidifier or heated tube settings, the level of mask leak,
and the duration of your sleep session.
Make sure that the humidifier water tank is filled to the
maximum fill line at the start of your sleep session. Check that
your mask is fitted properly, and adjust as needed to reduce
mask leak to normal levels.
Check therapy device air inlet is not obstructed, and filters are
free of debris and properly inserted. Confirm that the device,
humidifier water tank, and tube are connected properly and
not leaking. Confirm that the water tank lid seal is present and
properly seated.
