Cleaning any appliances is important as it will function better and last longer. We show you have to clean a dehumidifier to get the most out of it.

by Josh M

Just like other mechanical items in your home, your dehumidifier needs regular cleaning and maintenance to perform at its best.

Not sure where to start? We have plenty of tips on how to clean a dehumidifier in this handy guide.

While your dehumidifier may seem clean on the outside, you may be unaware of a potential problem growing internally. Some signs that you need to clean your dehumidifier include:

  • Increased allergy symptoms while in use.
  • Louder than usual noises from your dehumidifier while it is running.
  • A musty smell emanating from the machine when in use.
  • Black spots or mold can be seen on the inside.
  • It has been over a month since you cleaned it.

Dust, bacteria, pet dander, and dirt all accumulate inside your dehumidifier, spawning mold spores and other pollutants over time.

If your dehumidifier is allowed to run regularly without being cleaned, this can cause these spores to be released into the environment and affect your wellbeing. Regular cleaning and maintenance ensure any potential health risks are eliminated before they cause issues.
