How to Change The Wick Filter & Clean Your Humidifier

With the wick filter removed from the base, fill both sides of the base of the humidifier with one cup of undiluted white vinegar and allow to stand for about 20 minutes. You can use a soft cloth or brush to help with removal of scale build-up from the base of the unit. Instead of vinegar, you can also use specially formulated humidifier cleaner and follow the manufacturer's instructions for its use. Rinse the base thoroughly to remove all the cleaning solution. Now that scale has been removed, you can now disinfect the base, with a little of the water and bleach mixture from the water tank, let stand a few minutes and rinse the base.
