• Put some white vinegar into a glass, soak the filter in the vinegar for about 10
minutes.
• Remove the filter from the glass and shake it several times.
• Clean and rinse the filter once again with fresh water.
If you don't plan to use the humidifier for a long time, remove the filter from the water
tank and let it dry thoroughly, then wrap it in protective packaging and keep it next to
the humidifier in a cool, dry and dark storage space.
The following is not considered faulty operation:
• If your water is very hard (containing abnormally high levels of minerals) the
humidifier may produce white dust. This is not a malfunction. The solution would be
to clean the filter more often or use softer water.
• If you stand very close to the humidifier, you will hear the gurgling sound of water,
this is normal.
• The machine operate very quietly but it is not completely silent. Noise levels less
than 35 dB is considered normal.
