Solved – How to Clean a Dehumidifier? [+Step by Step] 2023

Do you know either dehumidifier get moldy or not? How to clean a dehumidifier? or what to use to clean a dehumidifier? Well! A dehumidifier is an appliance that removes moisture from the air in a room or area to improve air quality. Dehumidifiers come in a variety of sizes and can be used in small spaces, such as closets and pantries, or large areas, such as basements and garages.

Dehumidifiers are essential to keeping your home comfortable during the humid summer months. Not only do they help reduce the amount of moisture in the air, but they also help to reduce the risk of mold and mildew growth. However, dehumidifiers can become a breeding ground for mold and mildew if they are not cleaned on a regular basis. 

Dehumidifiers are often used in homes and businesses to help control the air’s humidity level. If the air is too humid, it can cause problems like mold and mildew. If the air is too dry, it can cause problems like static electricity and cracking paint. Either way, it is important to keep the dehumidifier clean so that it can work properly.

How to Clean a Dehumidifier: Step by Step

Follow these simple tips to clean your dehumidifier and keep it running efficiently.

1. Unplug your dehumidifier:

Unplugging your dehumidifier is an important first step in cleaning it. This will ensure that the appliance does not accidentally turn on while cleaning it. It is also important to unplug the dehumidifier before moving it, as this could cause damage to the appliance.

Unplug your dehumidifier and empty the water reservoir. Remove the filter and clean it with warm, soapy water. Rinse the filter and let it air dry. Wipe down the inside of the dehumidifier with a clean, damp cloth. 

2. Wipe the outside:

Use a soft, damp cloth to wipe down the exterior of your dehumidifier. Be sure to unplug the unit first. Assuming you would like a more in-depth explanation of how to clean a dehumidifier, dehumidifiers are wonderful appliances for helping to control the humidity level in your home. However, like all appliances, they require regular cleaning and maintenance in order to continue functioning properly. 

If you notice that the outside of your dehumidifier is starting to collect dust or other debris, it’s important to clean it off as soon as possible. The best way to do this is to use a damp cloth or sponge to wipe down the unit, being careful not to get any water inside of it. You may also want to use a mild cleaner if there is heavy build-up on the exterior.

3. Clean out the reservoir:

It’s important to clean out the reservoir of your dehumidifier regularly, as this is where all the water the appliance collects is stored. The reservoir is usually located at the bottom of the dehumidifier and can be accessed by unscrewing the unit’s housing. Once you’ve unscrewed the housing, you should be able to see the reservoir. If it’s full of water, empty it into a sink or drain. If there is any build-up of sediment or mold on the sides of the reservoir, give it a good scrub with a cleaning brush before rinsing it out. Once you’ve cleaned out the reservoir, screw the housing back on, and your dehumidifier should be ready.

4. Rinse the air filter:

Assuming you have already removed the filter from the dehumidifier (consult your owner’s manual to be sure), rinse it under cool water. Gently remove any debris or dirt that is clinging to the filter. Allow the filter to air dry completely before returning it to the dehumidifier.

It is important to rinse the air filter of your dehumidifier regularly in order to prevent it from becoming clogged with dirt and dust. To do this, remove the filter from the unit and rinse it under warm water. 

5. Remove dirt with a Vacuum:

There are a few different ways that you can clean your dehumidifier, but one of the most effective ways is to use a vacuum. Vacuuming will help to remove any dirt or debris that may be caught in the unit, and it will also help to circulate the air. If you have a handheld vacuum, you can use the attachment to reach the coils and other hard-to-reach areas—vacuum the unit’s interior, careful not to damage any delicate parts.

6. Remove and clean the bucket filter:

One way to clean a dehumidifier is to remove and clean the bucket filter. The bucket filter is located inside the dehumidifier and collects water from the air. Over time, the filter can become clogged with dirt and dust, which can reduce its efficiency. To clean the bucket filter, remove it.

How do you Clean a Moldy Dehumidifier Bucket?

Mold and mildew can build up on the inside of a dehumidifier bucket over time and, if not cleaned regularly, can become quite difficult to remove. The best way to clean a moldy dehumidifier bucket is to mix liquid soap and water in the reservoir and scrub the inside of the bucket with a brush or sponge. 

In addition, it is important to ensure that the bucket is dried thoroughly after cleaning, as mold can quickly grow back in humid environments. Rinse the bucket out well and let it air dry before reinstalling it. By taking these steps, you can be sure that your dehumidifier bucket will be free of mold and bacteria and will function properly once again.

Do Dehumidifiers get Moldy?

Yes, dehumidifiers can become moldy over time. This is because they provide the ideal conditions for mold, mildew, fungi and bacteria to grow. The coil, holding tank, filter and other dehumidifier parts can all become breeding grounds for these organisms. The dehumidifier can become a health hazard if not cleaned and maintained properly. 

However, dehumidifiers can become moldy over time, especially if they are not properly maintained. When a dehumidifier becomes moldy, it can release mold spores into the air, which can cause respiratory problems for some people. If you notice mold growing on your dehumidifier, cleaning it immediately and removing the mouldy parts is important. You should also regularly clean your dehumidifier to prevent mold growth.

How to Clean a dehumidifier quickly?

While an average dehumidifier may have a lifetime of a few years, the cleaning must be done at least once every couple of weeks, and beware – you may be underestimating how dirty the dehumidifiers can get.

Another important reason to maintain your dehumidifiers is to save costs – a clogged dehumidifier will be inefficient and also draw more power to get its job done, resulting in a spiked up energy bill

One final important note before we get working is to check your machine’s manual or manufacturer’s instructions for details on the build.


A dehumidifier is a great way to keep your home free of mold and mildew, but it’s important to clean it regularly to prevent build-up. Fortunately, cleaning a dehumidifier is easy — follow the steps in this article, and you’ll have it looking like new in no time. Thanks for reading.
