A humidifier can be great for dry skin and cool moisture in your house. If you are reading this, you probably want to learn how to clean a Honeywell Humidifier.  This article covers the necessary steps to do so.

When cleanliness and humidifier are mentioned in the same sentence, there are several variables to consider. For one, you will have to consider water changes and think about how to effectively eradicate mildew or mould.

Also, you will need to think about doing some occasional deep cleaning and disinfecting. This is because your humidifier filter and water reservoir can become dirty after a lot of use.

We’ll cover all of these in this article. Let’s get the ball rolling.

Deep Cleaning Your Humidifier

Deep cleaning your humidifier is very important and should not be taken for granted. This process is extremely useful when the Honeywell humidifier has been used for a long time, as there can be mineral deposits built up inside.

Your humidifier might also need a deep cleaning if you just recently put some perfume oils in it and want to ensure the additional residues don’t get stuck in it.

You will need to follow these steps to perform a deep clean:

  • Disassemble the humidifier as much as you can. Some Honeywell humidifiers don’t have any removable parts. Consult the owner’s manual to understand how much you can dismantle without damaging the unit.
  • Take the filter out to dry while you wash the humidifier. If your filter is not reusable, you should throw it out, especially if you notice mould growth. If the filter is still in good shape, use a microfiber towel or soft cloth to carefully dab it until visibly clean.
  • Next, use dish soap or undiluted white vinegar to clean the entire base and tank of the humidifier. Most Honeywell humidifiers can handle both cleaning products. White vinegar is great for eliminating mildew and mould, and dish soap works better for eliminating grease. With either product, use a sponge to clean the humidifier
  • Once everything has been scrubbed with soapy water, you should thoroughly rinse out the humidifier using cold and clean water. The great thing about this is that unlike cleaning many other small home appliances, you don’t have to worry about air drying. You simply need to reassemble the Honeywell humidifier following the instructions provided in the owner’s manual.
  • You can run your humidifier by filling it with a vinegar-water solution. For every gallon of water, you should add one cup of vinegar. Operate the humidifier for at least an hour, swirl the vinegar around, and throw it out. Doing this should get rid of any mineral buildup or oil lodged in the plumbing of the unit. You should not add your filter at this point. If you do, the vinegar solution may damage it.
  • The next step is to add fresh water to the humidifier and run it for at least an hour. Doing this with clean water gives the unit one final rinse. This process should be done outside. Your entire home can have the strong smell of vinegar if you rinse the humidifier
  • Reassemble the humidifier and add the filter or replace it if it is old. You need to make sure that all the parts are assembled correctly before you operate the humidifier

How to Properly Clean Your Honeywell Humidifier

Just as with various small appliances in the home, you can use a vinegar-based cleaning solution to clean your Honeywell humidifier.

More specifically, white vinegar is a great choice. Thanks to its high acid content, it can easily get rid of bacteria, odours, mould, and mildew without causing damage to the insides of the humidifier. For this reason, white vinegar is a great tool to use during weekly cleanings.

To clean the humidifier, you pour undiluted vinegar into your humidifier and turn it on. Allow the appliance to run for at least an hour. After this, rinse the unit with hot water.

Consider running the humidifier in a safe outdoor location, perhaps in your yard, garden, or shed. This is particularly necessary if you don’t like the sharp smell of vinegar.

Vinegar may have a strong smell, but it will not stain the humidifier. It will only remove any traces of bacteria or mould growing inside the unit.

The next step would be to get rid of the sour vinegar smell. There are a couple of tips and tricks to remove the somewhat offensive smell:

First, you can place a few drops of essential oil into the water tank of the humidifier. You can put approximately seven drops of your favourite essential oil. Essential oil is not fat-based, so it is appropriate for a humidifier and won’t cause any damage.

Another method for getting rid of the vinegar smell from your humidifier is to fill the tank with water and conduct a full run outside.

There are times when dilution can be a great tool over adding essential oils into your humidifier. You can try this method out, running the humidifier for an hour to see if the odour goes away.

Is Changing the Water in a Humidifier Important?

This is a common mistake with first-time owners. They tend to forget that the water in the humidifier needs to be changed daily.

Standing water is one of the factors that promote the growth of mould. Also, standing water could cause your Honeywell humidifier to become an active breeding zone for mosquitoes.

What Solutions Other Than Vinegar Can You Use to Clean a Honeywell Humidifier?

If you don’t like to use vinegar, probably because of the smell, there are other regular cleaning options. These include:

Diluted Bleach Solution

To use diluted bleach, you will need to mix a gallon of tap water with a teaspoon of bleach into the Honeywell humidifier.

Allow the mixture to sit for about an hour before you pour out the solution. Next, rinse out the humidifier with clean water. You might have to rinse out a couple of times to get rid of the bleach smell.

Hydrogen Peroxide

Pure hydrogen peroxide is efficient enough to get rid of the dirt and buildup in a humidifier. When cleaning your humidifier, you can simply add hydrogen peroxide to the tank. The hydrogen peroxide will eliminate any biological elements just as vinegar does without the smell.

Thoroughly swish the solution around and pour it out. Next, rinse the humidifier using cold tap water.
