Dehumidifiers are quite efficient in improving our indoor environment by lowering humidity levels. They operate by taking in air through a fan and chilling it on coils before reheating and releasing dry air. As a result, the collected water is generally collected in a bucket, which must be emptied when full.

Aside from emptying the bucket as needed, there are a few other things you should do to keep your dehumidifier in good working order. If you do not maintain the machine clean, its performance may suffer and it may waste energy.

Does a Dehumidifier Need to Be Cleaned?

Is it necessary to clean your dehumidifier? You might be shocked at how unclean a dehumidifier can become, so depending on usage, it should be cleaned on a regular basis. As we briefly said in the preceding stages, keeping the air filter clean is critical for the units’ efficiency. Furthermore, mould is the last thing you want to develop in the tank since it might contaminate the air.

How Often Should a Dehumidifier Be Cleaned?

Dehumidifiers must be cleaned on a regular basis in order to operate correctly. If you use it regularly, we recommend cleaning it once every three weeks.

Cleaning a Dehumidifier

Dehumidifiers have numerous critical components, such as an air filter and a reservoir, that will not operate properly if they are unclean. Here are the steps of cleaning a dehumidifier:


  • Before you begin cleaning your dehumidifier, turn it off and disconnect it from the power source. This guarantees that touching the item is totally safe.
  • Dehumidifiers take air in through vents, which may bring in a substantial quantity of dust and grime. The outer shell also traps larger particles that attempt to enter the dehumidifier.
  • To clean the outside, use a dry cloth to remove dirt and grime that has clung to it. If the dry towel isn’t doing the trick, dampen it somewhat. You may also need to apply some elbow grease.

Cleaning the Tank

  • Never splatter water or chemicals on the outside. This might cause harm to the dehumidifier’s internal and electrical components.
  • The removed water is collected in the dehumidifier’s tank or reservoir. It is critical to empty this anytime it becomes full, but it is also necessary to clean it on a regular basis. As a result, if you do not properly clean it, mould might begin to form within the tank.
  • If mould or mildew begins to grow within the tank, it has the potential to spread into the air and throughout your home. Mold can cause allergies and asthma attacks in people who are allergic to it.
  • To clean and disinfect the reservoir, you must first totally empty it. Then, fill it halfway with clean, warm water and one or two squirts of dish soap. Scrub it with a sponge, being sure to get into the corners.

White vinegar is a fantastic all-natural disinfectant. Although bleach is commonly used to eradicate mould, we recommend vinegar until the mould is actively developing in the tank.

Cleaning The Filter

  • The air filter is essential for both preserving the internal elements of the dehumidifier and purifying the dry air. If the air filter is clogged and unclean, the dehumidifier will not function since air cannot flow through.
  • If you’re not sure where the filter is, see the user handbook. Some units have it at the rear, which allows you to slide it out after removing the tank. After removing the filter, check it to see whether it needs to be replaced. Dehumidifiers, in general, utilise washable or reusable filters, although even these must be replaced at some point.
  • If it’s still functional, begin by giving it a quick vacuuming to remove any loose debris or dust.
  • Allow the air filter to soak in the solution for up to 10 minutes. Before placing it back into the dehumidifier, make sure it is totally dry.
  • Most dehumidifiers come with instructions on how to properly clean the air filter. Some require simply warm water and a light detergent, while others may be vacuumed. Check the handbook to make sure you aren’t harming the filter.

Cleaning the Bucket Filter

The bucket filter collects any pollutants that make their way into the dehumidifier. This tiny filter is not found in all dehumidifiers. However, if yours does, it is critical to clean it to prevent blockages.

  • Simply take it out and clean it with warm water. After that, let it dry before reinstalling it.

Plug It In

When you’ve cleaned all of the components and they’re fully dry, it’s time to put them back together.

  • Plug in the dehumidifier and turn it on to test whether it works properly. Next, examine the display to see if there are any indicators of a problem. Finally, let the unit run for a couple of hours before checking the reservoir and humidity to ensure that everything is working properly.

How to Clean a Dehumidifier Bottom Line

Cleaning your dehumidifier is critical, and it should be done before dirt and mould accumulate.

Most dehumidifiers come with instructions on how to clean them. Some even have indications on the screen to alert you. However, it is still necessary to examine the filter and bucket on your own.

Fortunately, you don’t need any additional materials or cleansers to keep the dehumidifier in good working order. A small amount of mild detergent, vinegar, and warm water should suffice. Good luck with your cleaning!
