Also, when cleaning the base, ensure there is no water getting into the circuitry. This is one of the reasons of humidifier not working after cleaning.

What happens if you don’t clean your humidifier?

Because of its constant contact with water, bacteria, fungi, and viruses will breed in the tank. They will be pumped out with the mist, and your family will inhale them.

If you see pink mold in the humidifier, it means you are inhaling it with the mist. Clean the tank thoroughly.

Remember, you can experience serious mold exposure symptoms in toddlers if you run a humidifier without cleaning it.
