A dehumidifier is an appliance that removes excess moisture from the indoor air. This is very beneficial to you in many ways.

Steps in Cleaning your Dehumidifier

Step 1:

Remove the water collection tank from the appliance. In most cases the water tank is removable. Drain the water accumulated from the water collection tank. Rinse it in cold water in the sink. The water collection tank is a target area for a buildup of all kind of dirt and molds. Check for any debris or mold at the bottom of the tank. Wipe it clean with a cotton rag and leave to air dry.

Step 2:

Your dehumidifier should have a removable air filter. Take that air filter out of the appliance. Check the amount of dust and dirt that is trapped in the air filter. If the dirt and grime are excessive then you have to replace the air filter with a new one as specified in the manual. If the air filter appears mildly blocked then clean the filter as specified in the manual. Otherwise mix a solution of water and liquid bleach in a ratio of  1:1 and let the filter soak in this mixture for half an hour. Now rinse with fresh water and clean the air filter with a light brush. Air dry it completely.

Step 3:

Now disassemble the outer cover of the dehumidifier. Use an appropriate screwdriver to loosen the screws and then lift off outer cover. Now you will be able to see the inner parts of the dehumidifier such as coils, fan blades etc.

Step 4:

Clean the coils in the dehumidifier using a soft brush. There can be a lot of buildup of dirt if the dehumidifier has been used for a long time without cleaning. This accumulated dust can reduce the efficiency of the dehumidifier.

Step 5:

Clean the fan blades using a soft damp cloth. The cleaning of the fan will also increase the efficiency of the dehumidifier.

Step 6:

Look at the rest of the interior and wipe out any dust or debris that you may find.

Step 7:

Assemble the outré cover of the dehumidifier.  Install the filter in its place.

Step 8:

Connect to a power outlet by plugging it in. Turn it on and check for any abnormal noise. If everything is perfect then your job is complete.
