CARE &
MAINTENANCE
IMPORTANT TIPS
Figure 2.1 Figure 2.2
Figure 2.3
• Never pour water directly into the
base chamber. [Figure 2.1] Only add
water to the water tank. The humidifier
will automatically release the correct
amount of water into the base chamber.
• Avoid moving or shaking the humidifier.
[Figure 2.2] This may cause the water
tank to release too much water into the
base chamber.
• Before moving the humidifier, turn it o,
unplug it, and remove the water tank.
• If your humidifier doesn’t produce mist
correctly, check the max water line
[Figure 2.3] to see if there is too much
water in the base chamber. Pour out
any extra water if water is over the max
line.
Note:
• All maintenance should be done on
a water-resistant surface, such as a
kitchen counter.
• Change the water daily to avoid
bacteria growth.
• Use a tissue or cloth to clean the nozzle
regularly.
• If not using the humidifier for 1 week or
longer, do not leave water inside. Clean
and dry the humidifier instead.
Note:
• Never immerse the base in water or
liquid. Do not place any part of the
humidifier in a dishwasher.
• Do not use detergents to clean the
humidifier.
Cleaning
You should clean your humidifier every week,
and when you’re ready to store it.
1. Unplug the humidifier and remove the
power adapter from the base.
