How Do You Store a Dehumidifier?

Sep 1, 2026 / Public Storage

Store a dehumidifier in a storage unit by emptying the water tank, cleaning the appliance, drying every component completely, and packing it upright in a sturdy box or bin. Remove or clean the filter according to the manufacturer’s instructions, wrap the cord separately, and place the unit on shelving or another raised surface.

Do not store a dehumidifier with water in the tank, a damp filter, or moisture inside the unit. A fully dry appliance is easier to put away and use again when the season changes.

Dehumidifier Storage Essentials:

Empty the water tank and drain any remaining water before packing.
Clean the tank, exterior, air intake, and removable parts according to the manufacturer’s instructions.
Remove, clean, or replace the filter based on the appliance manual.
Allow the tank, filter area, and unit to dry completely.
Use the original box when available or a sturdy box that fits the unit upright.
Wrap the power cord separately to prevent tangling.
Do not stack heavy boxes on top of the dehumidifier.
Place the packed appliance on shelving or another raised surface.

How Do You Clean a Dehumidifier Before Storage?

Clean a dehumidifier before storage by emptying the water tank, wiping the appliance, and following the manufacturer’s instructions for the filter and removable parts. Use a soft cloth to remove dust from the exterior and air intake areas.

Let every part dry completely before packing. Do not put away the dehumidifier while the tank, filter compartment, or internal areas are still damp.

Should You Remove the Dehumidifier Filter Before Storage?

Remove the dehumidifier filter before storage if the manufacturer’s instructions direct you to do so. Clean reusable filters or replace disposable filters before using the appliance again.

Keep the filter with the dehumidifier only when it is fully dry. Check the appliance manual for filter-care instructions specific to your model.

How Should You Pack a Dehumidifier for Storage?

Pack a dehumidifier upright in its original box when available. If the original packaging is unavailable, use a sturdy box or bin that supports the appliance without leaving excessive empty space.

Use this packing process:

Empty and clean the dehumidifier.
Let the appliance and removable parts dry fully.
Wrap the power cord and place it beside the unit.
Put removable parts in a labeled bag or container.
Add packing paper or soft materials around open areas.
Keep the dehumidifier upright in the box.
Seal and label the box.

Label the container “Dehumidifier” and note the room where you plan to use it.

Should You Use Climate-Controlled Storage for a Dehumidifier?

Climate-controlled storage can be a useful option for a dehumidifier because it is designed to maintain more consistent temperature or humidity levels than non-climate-controlled storage. Compare available unit types at your preferred Public Storage location before reserving.

The dehumidifier still needs to be empty, clean, and fully dry before it goes into storage.

Where Should You Place a Dehumidifier in a Storage Unit?

Place a dehumidifier on shelving or another raised surface rather than directly on the floor. Keep the box near the entrance if you expect to bring it home during a humid season.

Store the dehumidifier with related seasonal household items, such as fans, extra bedding, or room organizers. Keep heavier boxes on lower shelves and leave a walkway so you can retrieve the appliance without moving other containers.

Put Away Your Dehumidifier With a Clear Plan.

A dehumidifier is easier to store when it is empty, clean, dry, and packed upright. Clean the tank and filter area, wrap the cord, label the box, and place the appliance where it is easy to retrieve later.

Find a Public Storage location near you to reserve space for household items you want to put away between seasons. A simple storage layout can help you organize seasonal appliances without crowding closets and utility areas.

A few minutes of prep can make the next seasonal change easier to manage.
