How do I store a home dehumidifier during the off - season?
Jun 11, 2025
Hey there! As a home dehumidifier supplier, I often get asked about how to store these handy devices during the off - season. It's a crucial question because proper storage can extend the lifespan of your dehumidifier and ensure it's ready to go when you need it again. In this blog, I'll share some tips and tricks based on my experience in the industry.
First things first, why is it important to store your dehumidifier correctly? Well, if you don't store it properly, you might face issues like mold growth, damage to the internal components, and even a decrease in its efficiency when you use it again. And let's be honest, nobody wants to deal with a malfunctioning dehumidifier when the humidity starts acting up.
Step 1: Clean Your Dehumidifier Thoroughly
Before you even think about packing it away, you've got to give your dehumidifier a good clean. Start by unplugging it from the power source. Safety first, right? Then, empty the water tank. You don't want any standing water in there during storage as it can lead to mold and mildew.
Next, take out the air filter. Most dehumidifiers have easily removable air filters. Use a vacuum cleaner with a brush attachment to gently remove any dust and debris from the filter. If the filter is really dirty, you can wash it with mild soap and water. Just make sure it's completely dry before you put it back in.
For the exterior of the dehumidifier, use a soft, damp cloth to wipe it down. You can use a mild cleaning solution if there are stubborn stains, but avoid getting water inside the unit.
Step 2: Find the Right Storage Location
Once your dehumidifier is clean, it's time to find a suitable place to store it. The ideal storage location should be dry, cool, and well - ventilated. A basement or a garage can work, but make sure they're not prone to flooding or extreme temperature changes.
Avoid storing your dehumidifier in direct sunlight. The heat from the sun can damage the plastic parts and affect the internal components. Also, keep it away from any sources of moisture, like leaky pipes or wet walls.


If you're short on space, you can store it upright. However, if you need to lay it down, make sure it's on a flat surface. Just be aware that laying it down for an extended period might cause some issues with the refrigerant flow in some models.
Step 3: Protect the Dehumidifier
To give your dehumidifier some extra protection during storage, you can cover it with a dust cover. You can buy a specialized dehumidifier dust cover or use an old bedsheet. This will prevent dust and dirt from settling on the unit.
If you have the original packaging, that's even better. The original box is designed to protect the unit during transportation and storage. It usually has padding to absorb any shocks and keep the dehumidifier safe.
Step 4: Consider the Storage Duration
The length of time you're storing your dehumidifier can also affect how you store it. If it's just for a few weeks, you might not need to take as many precautions. But if it's for several months, you need to be more thorough.
For long - term storage, you might want to run the dehumidifier for a short period every few months. This will help keep the internal components lubricated and prevent any seals from drying out.
Step 5: Check Before Reusing
When the off - season is over and you're ready to use your dehumidifier again, don't just plug it in and start it up. First, give it a quick inspection. Check the power cord for any signs of damage. Look at the water tank and make sure it's clean.
If you had removed the air filter for storage, put it back in. Then, plug in the dehumidifier and turn it on. Let it run for a few minutes to make sure it's working properly.
