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.
