How to Clean a Humidifier Filter

Humidifiers are perfect because they add moisture to the air during the cold winter months. There are so many benefits to owning a humidifier. Your humidifier should be maintained properly or else it won’t keep clean moist water in the air and can cause problems.

The humidifier is very important to maintain. It acts as a wick, bringing water up from the reservoir and exposing it to the moving air of the fan. Do you actually change the water every day? The water in the humidifier can cause bacteria, molds, and fungi breed can grow if the filter and water is not cleaned.

Follow these instructions in order to clean your humidifier.

1.       Unplug your humidifier.

2.       Remove and empty the water tank. When you fill the reservoir add a teaspoon of baking soda to keep the water smelling nice and clean.

3.       Remove the dirty filter. Most removable air filters are located inside the humidifier’s motor housing. If your humidifier has a paper filter then you can just throw it out and replace it with a new one.

4.       Clean the filter. Rinse the filter with cold water. If there is any dust or dirt you can use a brush with a soft bristle in order to get rid of them. If your filter is dusty or mildly dirty you can just rinse it. If there is buildup or mold then mix a solution of either white vinegar or bleach.

Cleaning with White Vinegar

·         Pour in distilled white vinegar. Add one part vinegar for every two parts water and mix this solution together.

·         Soak the filter for approximately 30-45 minutes or longer if your filter is very dirty.

·         Then run the water through clean water then let it air dry.

 Cleaning with Bleach

·         File a large container with warm water.

·         Add a teaspoon of bleach for every gallon of water. That way the bleach will be diluted. Be sure to wear gloves because bleach can damage your skin.

·          Let the solution sit for roughly 10 minutes.

·         Then run the water through clean warm water then let it air dry.


5.       Let the filter air dry. Allow your filter to air dry (this is the safest option). It should take one to two hours for it to dry. Mold grows in an environment with moisture, having clean water and a dry filter will prevent mold and bacteria from growing.

6.       Reassemble your humidifier. Place all the parts back together.

7.       Plug in your humidifier and you’re all set!

Proper maintenance of your humidifier can help with your allergies and dry skin and lips during the cold winter months.
