The white deposits are called scale and they consist of minerals from the
water. Scale on the humidiication ilter 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 humidiication performance. Clean the humidiication ilter
frequently to remove the scale, and replace the humidiication ilter every
three month.

When mist is very ine, it is invisible. This humidiier has a NanoCloud
humidiication technology, which produces healthy humid air from the
outlet area without formation of water mist.Therefore, you cannot see the
mist.
