How to Clean a Humidifier

Depending on how dirty the work is, there are many options for doing it. We’ll teach you how to clean your humidifier in the most frequent methods, starting with a simple clean that you may conduct on a regular basis.

Make sure your humidifier is unplugged before you begin. To avoid burns, let a warm-mist humidifier cool for 30 to 60 minutes before touching it.

Basic Humidifier Cleaning

Depending of how often you use your humidifier, basic cleaning should be done on a regular basis. It’s quick and easy, and all you’ll need is the following:

Remove the humidifier’s filter after disconnecting it and rinsing it with cold water under the running faucet. Turn it every now and again to make sure it’s clean on both sides. The filter should then be placed on a clean cloth to dry.

Consider changing your filter if it is beginning to show signs of wear. You can find instructions on how to change it and how often it should be done in the handbook.

Cleaners and chemicals should not be used on the filter since they can harm it.

Empty the contents of the tank from the humidifier into the sink or drain. Then, half-fill it with pure white vinegar and swirl it about to coat the bottom and sides. Allow at least one hour for the vinegar to settle in the tank.

Vinegar is a natural cleaner with a lot of power. It removes mineral build-up and limescale effectively because to its strong acid content. It can even get rid of mould.

If your tank is unclean, gently scrub the bottom and sides with a sponge. You may also use a cotton swab to get into those hard-to-reach places.

If your tank is tiny, you can also mix a little handful of rice with the vinegar and shake it.

When cleaning your humidifier, avoid using any other forms of professional cleaners

Rinse the tank well with cold, clean water after dumping out the vinegar. To get rid of the vinegary smell, you may need to rinse it many times.

It’s time to finish up with the frame now that the tank is spotless. Simply clean the entire frame with a sponge dampened in a vinegar and water combination. Keep an eye out for any wrinkles or crevices around the panel or dial.

Wipe the frame and tank with a clean towel to remove any excess water. Fill the humidifier with water, replace the dry filter, and enjoy a fresh mist.

Even after cleaning, a chemical residue might be pushed back into the air. Vinegar is a natural product that will not damage you.

How To Disinfect A Humidifier

Cleaning the humidifier is necessary every now and again. Mold, bacteria, and pollutants are all likely to live in the tank and outflow, as we discussed before. Here are some suggestions for keeping your humidifier clean.

Bleach, vinegar, and peroxide are used in the following techniques, however they should never be used together. Toxic vapours or byproducts can be produced when chemicals are mixed, posing a risk to you and your family. Rinse thoroughly using one of the techniques listed below.


Although bleach is a harsh chemical, it is occasionally essential to clean the tank adequately. Fill the tank halfway with clean water and one to two tablespoons of bleach, depending on its size. To sterilise the tank, let the solution rest for up to an hour. If you leave it any longer, the bleach will do harm.

After an hour, dump the solution into a sink or drain and thoroughly clean the tank with cold water. Before putting it back on the frame, make sure it’s been well cleaned.


Fill the tank with one cup of vinegar and the remainder with clean water. Place the tank on the frame and operate the humidifier for one hour, allowing the vinegar to clean the mist exit. Indoors, avoid using the humidifier since it will give off a strong vinegar odour.

Chemical cleaners like bleach should never be used since they will harm the humidifier’s internal components. It will also disperse the pollutants in the air.

After the hour has passed, empty the tank and rinse it with clean water. Fill it with fresh water and run the humidifier for an hour to flush out any vinegar that may have accumulated in the outlet. Rinse the tank one at a time.

If the manufacturer recommends it, never add essential oils to your humidifier to get rid of the vinegary smell. Essential oils have the potential to harm the humidifier. Rather, thoroughly rinse with water until the odour is gone.

Hydrogen Peroxide

Peroxide is a gentler version of bleach that is as effective. Simply fill the tank halfway with peroxide and swirl it around to completely coat the bottom and sides. Allow up to an hour for the peroxide to settle in the tank before dumping it out. After that, thoroughly rinse with cold water.

Regular Maintenance On Humidifier

Cleaning your humidifier isn’t something you do every day. There are, however, some things you should do on a daily basis to keep germs at away.

Your humidifier may contain more than a gallon of water, but it has to be emptied unless you plan on using it continually.

Mold and germs will form if you leave the water in the tank for an extended length of time. To minimize bacterial development or mould, we recommend emptying your humidifier every day or every other day.

We recommend cleaning your humidifier every three days, depending on how often you use it. Using one of the following procedures, you may either conduct a simple clean or disinfect the tank. Every two weeks, give the humidifier a thorough cleaning.

Humidifiers are helpful, but they may be overbearing at times. It’s critical to look for indicators of wetness or excessive moisture in the surrounding environment. If the humidifier is set to a high level, mould and bacterial growth may develop in the tank and surrounding area.

Turn the device down or off as soon as you feel the air is at an acceptable humidity level to avoid this possible issue.

It’s critical to keep your humidifier correctly if you only use it during dry seasons, such as winter. Make sure the tank is totally emptied and cleaned before storing it away. To eliminate any excess moisture, wipe the tank and frame with a clean cloth.

Additionally, give it a brief clean when you pull it out of storage to ensure there are no contaminants.

Sometimes may be difficult to say goodbye to a trusty appliance, but it is unavoidable. If you’ve used a humidifier for a long time, it could start to break down. Furthermore, worn-out components are more likely to have a high level of bacterial development.
