You should clean your cool mist humidifier each day. Empty the water tank, rinse it out, and allow it to dry out a bit before replacing it. More serious cleaning requires removing the scale and disinfecting the unit to prevent the growth of algae, bacteria, and slime. Descale and disinfect your cool mist humidifier at least once each week.

Dry the wicking filter out. Remove and empty the water tank. With the cool mist humidifier switched off, remove the water tank and dump the water out into your sink or tub. Without replacing the water tank, turn the machine on. This will allow the wicking filter to dry out. When you’re done, turn the cool mist humidifier off and unplug it from the electrical outlet.
-
Remove the wicking filter. The wicking filter is the part of the cool mist humidifier that holds moisture. When dry air moves through the filter, it becomes humidified, and produces vapor. [2] X Research source In some cool mist humidifiers, the filter is an open-ended cylinder, while in others it is a flat piece. In either case, it has a sort of spongy, mesh-like appearance.
- You might need to disassemble the cool mist humidifier’s housing to access the filter.
- Handle the filter gently to avoid tearing it.
- The wicking filter removal process will vary depending on what sort of cool mist humidifier you have. Consult manufacturer directions for more information about removing your wicking filter.
-
Remove the water tray. The water tray is the pool below the cool mist humidifier that the water tank drains into. The water tray might slide out or need to be unclipped from the base of the humidifier.
-
Clean the water tray with vinegar. Use white vinegar to fill the water tray about halfway. Allow the vinegar to stand for 20 minutes. With the vinegar in the tray, use a sponge dampened slightly with vinegar to wipe the parts of the tray that are not submerged. Be careful not to splash any vinegar on the surface where you’re cleaning the water tray. [3] X Expert Source Victor Belavus

Rinse the water tray. After you’ve wiped the water tray down and allowed the vinegar to stand for 20 minutes, rinse it off completely with warm water, or place it in the top shelf of your dishwasher and turn it on. When the tray has been thoroughly rinsed, dry it by hand with a clean, dry dish rag. Set it on your dish rack to allow excess water to evaporate.
- Do not immerse the water tray in water.

Clean the water tank. Fill the water tank with about half a gallon of water and two tablespoons of white vinegar. Replace the cap.

Empty the liquid from the water tank and refill it with clean water until the smell of bleach is no longer present. Wipe the inside of the water tank and allow to air dry.
-
Wipe the water tray. Wet a sponge or soft rag with a solution made of one tablespoon of bleach and one gallon of water. Wipe the water tray down with the sponge or rag. When finished, rinse it thoroughly under the sink or place it in the top shelf of your dishwasher and turn the unit on. Allow the water tray to dry before reassembling.

Wipe the outside of the humidifier. Use a clean, damp rag to wipe down the base and outside of the cool mist humidifier. Do not submerge the base in water or you could damage it and risk injury the next time you turned the device on.
