The following steps show how to clean a warm air humidifier.
Add 1 teaspoon of chlorine to a gallon of water in the humidifier. Make sure all sides are wet.
Let the mixture soak in the device for about 20 minutes.
Thoroughly rinse the device of all chlorine before use.
Cleaning a cool air humidifier entails a different process.
Make sure to remove the tank and water filter. Empty any remaining water from the base and tank.
If it has been 3 or 4 months since the wick filter has been put in, change the wick filter.
