Problem
Why it happened What to do
The airflow is
much warmer
than usual.
The air filters may
be dirty. The
device may be
operating in direct
sunlight or near a
heater.
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 devicec is away from
direct sunlight and heating equipment.
If the problem continues, contact your home care provider.
The water in
the humidifier
water tank
runs out
before
morning.
Humidifier water
tank was not
full at start of
session. Mask
leak is excessively
high. The ambient
conditions are
very dry/cool.
Under most conditions, a full humidifier water tank should last
for a typical 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.
I hear a leak
or whistling
sound
coming from
my therapy
device (not
related to
mask leak).
The therapy
device air
inlet may be
obstructed. The
tube is not fully
connected.
The humidifier
seals are not fully
seated or are
missing.
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.
