• Make sure that the humidifier is well assembled/connected
every time after you clean it or after you remove the upper
unit and/or water tank for refilling.
• Make sure that the water tank is properly placed. If the
problem persists, contact the Consumer Care Center in your

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 6 months.
• Make sure that the water tank is filled with water.
• Clean the humidification filter (see chapter 'Cleaning the
humidification filter').
Plug the humidifier into the power supply and switch on.
• When mist is very fine, it is invisible. This humidifier has a
NanoCloud humidification technology, which produces
healthy humid air from the outlet area without formation of
water mist. Therefore, you cannot see the mist.
