CLEANING
•	 Always unplug the unit before servicing in any way.
•	 The water temperature of the water remaining in the unit after use may be high, allow 
time for it to cool.
GENERAL CLEANING
• Inside the base of the unit. Pour excess water out of the unit. Wash out the unit with fresh
water using the cleaning brush and a soft cloth as needed.
Do not submerse the base of the
unit into water, or allow water to enter inside the dry air exhaust port of the unit.
• Water tank. Empty water tank. Remove mist nozzle and clean the mist tube with fresh water
and a light brush (bottle cleaning brush is recommended).
• Outer surface of the unit. Wipe the surface of the unit with a soft, damp cloth if needed. If
you notice an accumulation of water during usage, reduce humidity and dry outer surface with
a cloth.
DESCALING
• Depending on usage and water type, cleaning to remove scale may be required
weekly or every other week to optimize unit performance.
• If you live in a hardwater area, we recommend the use of distilled water for your
humidifier. This will help reduce the precipitation of minerals or ‘white dust’.
• Do not clean the unit or water tank with detergents or cleaning chemicals of any kind.

1. Unplug unit.
2. Remove the tank and empty all water from unit base and tank.
3. Locate the ultrasonic disk on the inside center of the base unit. (see pg. E-4)
4. Use ONLY the enclosed cleaning brush to gently clean disk and remove build up and deposits.
