How to Store a Humidifier

Nov 6, 2025 / Public Storage

You can store a humidifier in a storage unit by cleaning it thoroughly, drying it completely, and packing it carefully to prevent damage or mildew. Stashing a humidifier might sound simple, but a little prep goes a long way.

Clean and Dry Before You Pack

Empty any remaining water and dismantle removable parts like the tank, filter, and nozzle. Give each piece a wash with warm, soapy water, rinse thoroughly, and let everything dry completely. Any leftover moisture can lead to mold, so don’t skip the drying step. Once all the parts are dry, give the main body a quick wipe with a soft cloth to get rid of dust or residue.

How Should You Pack a Humidifier for Storage?

When packing a humidifier, using its original box is best if you still have it. If not, choose a sturdy cardboard box and wrap each part in bubble wrap or packing paper. Keep smaller pieces like filters and screws together in labeled bags to avoid losing them. If it fits, nest the tank and nozzle inside the main body, then fill any gaps with packing paper to keep everything from shifting around.

Pick the Right Spot in Your Storage Unit

Humidifiers should be stored somewhere that avoids extreme temperatures. A climate-controlled storage unit works best because it keeps plastic parts from warping and prevents any lingering moisture from turning into mildew. Keep your humidifier off the floor by placing it on a shelf or a wooden pallet—this adds airflow and keeps it away from any damp spots that could sneak in at the base of your unit.

Label and Keep in Reserve

Label your box clearly so you know exactly what’s inside. Keeping it in reserve for dry months helps you declutter your space without losing your comfort. When you need it, the label makes it easy to grab your humidifier without digging through everything else in your unit.

Storing a humidifier at Public Storage is easy when you take a little time to clean, dry, and pack it thoughtfully. Pick a climate-conscious spot, label your box, and your humidifier will be ready to restore cozy, breathable air to your home whenever you’re ready to bring it back out.
