Follow steps 1-3 under Before Cleaning then follow the additional steps below. Filter must be
removed from humidifier during cleaning; do not clean Filter with vinegar. Do not attempt to
clean the Wicking Filter with vinegar or any chemical solutions. Doing so may damage
the Filter.
1. Pour 2 cups of undiluted distilled white vinegar in Water Tank. Replace Tank Cap and
secure tightly by turning clockwise (to right). Swish vinegar around in Tank to wet entire
inside of Tank.
2. Place Tank on Base. Vinegar solution will drain into Water Reservoir and loosen mineral
buildup (scale) in Base, Reservoir and bottom of Water Tank. Note: Allow vinegar to remain
in the Tank and Base for 20 minutes.
3. After soaking, empty vinegar from Water Tank. With vinegar in the Base, clean all interior
surfaces with a soft cloth or brush to help remove scale.
4. Rinse Water Tank, Base and Reservoir with water until the smell of vinegar is gone.
NOTE: Consider using a Protec Humidifier Cleaning Ball to keep your humidifier
cleaner longer. Protec Cleaning Ball continuously cleans and protects
against bacteria and mold. It also helps prevent the buildup of slime in the
water and on humidifier surfaces. The Protec Cleaning Ball will keep your
humidifier cleaner longer between cleanings. However, your humidifier
still needs to be cleaned regularly.
