How to clean a dehumidifier
Step 1: Unplug the dehumidifier
The first step is to unplug the dehumidifier, to make sure that it’s safe to clean. Make sure it's not connected to any power source for safe cleaning.
Step 2: Remove and vacuum the filter
Next, carefully remove the filter from the dehumidifier, before using a vacuum cleaner to suck up as much dirt and debris as possible.
Step 3: Wash the filter
Fill the sink (or a bucket) with warm soapy water and use it to wash the filter in, making sure to remove all remaining dirt and debris. Then, once the filter is clean, use fresh water to wash off any soap, before leaving the filter to completely dry.
Step 4: Clean the water reservoir
Next, empty and clean the water reservoir.
Josh Mitchell, a HVAC Technician, explains: "Remove the water collection bucket and dispose of the water. Clean it with a mild detergent, [we recommend this list of our favorite highly-rated eco-friendly detergents for the best buys] and warm water. Rinse well and either dry it with a clean towel or let it air dry."
Step 5: Clean the coils with a vacuum cleaner
While your filter is drying, take the time to clean the dehumidifier’s coils; these can usually be found at the back of the dehumidifier. Use a vacuum cleaner on a low setting to carefully vacuum up any dirt and debris from the coils.
Step 6: Brush and spray the coils
Next, use a soft brush to gently brush dirt and debris away from the coils, before spraying them with a mix of one part vinegar to three parts water. Use the brush to clean the coils down, before wiping off the excess cleaning solution with a clean damp cloth.
Step 7: Allow the coils to dry
Once all clean, leave the coils to dry completely before you put the filter back into the dehumidifier and start using it again.

Meet the experts
If you've been using a dehumidifier to dry laundry, you may find that long-term exposure to damp conditions has allowed yours to develop mold. To clean mold out of a dehumidifier, use all the steps above, but if it doesn't go away, one really powerful but natural option is to use baking soda as a cleaning agent.
Simply remove the parts that are harboring mold, spray with water, sprinkle with baking soda, and allow to soak. After an hour, clean off the baking soda paste with a toothbrush dipped in warm soapy water, rinse, and allow to dry before replacing.
