It is best to keep the humidity level between 30~50 percent of relative humidity.
The comfort level of humidity will vary from room to room and with changing room conditions.
In cold weather, windows and sometimes walls may fog or develop frost from excessive indoor
humidity. If this occurs, reduce the mist intensity setting to avoid damage from condensed water
dripping on windowsills.
Too much humidity in the room may allow moisture to accumulate on surfaces where bacteria and
fungi can grow. Moisture that gathers may also damage furniture, walls and wallpaper.
To eliminate excessive humidity, especially in smaller rooms, leave the room door or window open
and adjust the mist intensity control accordingly.
Lift and remove mist nozzle.
Remove water tank by grasping firmly and lift up.
Turn water tank over and turn the cap counter-clockwise to open. Fill with COOL tap water or

Replace the fill cap by turning clockwise – do not over tighten.
NOTE: When carrying a filled water tank, place one hand under for support.
Place water tank back in place, making sure the tank is correctly aligned with the body; then replace
the mist nozzle.
