Make sure that the water tank is filled with water and placed properly into the

The humidification filter is dirty. Rinse and/or descale the humidification

•
Your room might have too much ventilation. Please close doors and
windows.
•
Your room size is too big. The recommended room size is 50m² for both
HU4902 and HU4903.
The white deposits are called scale and they consist of minerals from the water.
Scale on the humidification filter affects the humidifying performance, however
it does not harm your health. Please follow the cleaning instructions in the user
manual.
The yellow deposits is a natural effect of the wick material, and it has no impact
on humidification performance. Clean the humidification filter frequently to
remove the scale, and replace the humidification filter every three month.
