How do I clean the coils of my whole home dehumidifier?
Dec 04, 2025
Hey there! As a supplier of whole home dehumidifiers, I know how important it is to keep your dehumidifier in top - notch condition. One of the key maintenance tasks is cleaning the coils. In this blog, I'll walk you through the process of cleaning the coils of your whole home dehumidifier, so it can keep your home dry and comfortable.
Why Clean the Coils?
First off, let's talk about why coil cleaning is a big deal. The coils in your dehumidifier play a crucial role in the moisture - removal process. They cool the air, causing the water vapor to condense into liquid water, which is then collected in the reservoir.
Over time, dust, dirt, and other debris can build up on the coils. When this happens, the dehumidifier has to work harder to cool the air. This not only reduces its efficiency but also can lead to higher energy bills. Plus, a dirty dehumidifier may not be able to remove as much moisture from the air as it should, leaving your home feeling damp and uncomfortable.
Tools You'll Need
Before you start cleaning the coils, gather the following tools:


- A soft - bristle brush: This can be a small paintbrush or a specialized coil - cleaning brush.
- Compressed air canister: You can find these at most hardware stores.
- Mild detergent: Something like dish soap will work just fine.
- A bucket of warm water.
- A clean cloth or sponge.
Step - by - Step Cleaning Process
1. Unplug the Dehumidifier
Safety first! Before you start any maintenance on your dehumidifier, make sure it's unplugged from the power source. This will prevent any risk of electric shock.
2. Locate the Coils
The coils are usually located at the back or the front of the dehumidifier, behind a grille or cover. You may need to remove a few screws or clips to access them. Be careful when removing the cover so you don't damage it.
3. Remove Loose Debris with the Brush
Take your soft - bristle brush and gently brush away any loose dust and dirt from the coils. Start from the top and work your way down, being careful not to bend the delicate fins of the coils. You can also use the brush to clean around the edges of the coils.
4. Use Compressed Air
Next, use the compressed air canister to blow out any remaining debris from the coils. Hold the canister about 6 - 8 inches away from the coils and spray in short bursts. Move the canister around to cover the entire surface of the coils. The compressed air will dislodge any stubborn dirt that the brush couldn't remove.
5. Prepare the Detergent Solution
In your bucket of warm water, add a small amount of mild detergent. Mix it well until it forms a soapy solution.
6. Clean the Coils with the Detergent Solution
Dip your clean cloth or sponge into the detergent solution and wring it out so it's damp, not soaking wet. Gently wipe the coils with the damp cloth or sponge. Make sure to clean both the front and the back of the coils. The detergent will help break down any grease or grime that has built up on the coils.
7. Rinse the Coils
After cleaning the coils with the detergent solution, use a clean, damp cloth or sponge to rinse off the detergent. Make sure to remove all the soap residue from the coils.
8. Dry the Coils
Let the coils air - dry completely before reassembling the dehumidifier. This may take a few hours, depending on the humidity in your area. You can also use a fan to speed up the drying process.
9. Reassemble the Dehumidifier
Once the coils are dry, carefully put the cover back on the dehumidifier and secure it with the screws or clips.
Frequency of Coil Cleaning
How often you should clean the coils depends on how often you use your dehumidifier and the environment it's in. If you use your dehumidifier frequently or if you live in a dusty area, you may need to clean the coils every 1 - 2 months. If you use it less often or in a cleaner environment, cleaning the coils every 3 - 4 months should be sufficient.
