How to Use a Dehumidifier for Drying Clothes Indoors

Quick answer: Yes, a dehumidifier can help dry clothes indoors. By continuously removing moisture from the air, it lowers the room's relative humidity (RH), which allows wet fabric to release water vapor more efficiently. This makes it a practical option during winter, rainy days, and in apartments or homes without a tumble dryer.

Drying clothes indoors creates a real problem. Moisture from wet laundry builds up in the air, slows evaporation, and can lead to condensation, mold, and musty smells. A laundry dehumidifier helps manage all of this at once—not just speeding up drying, but also protecting your home from excess humidity.

This guide covers how to use a dehumidifier to dry clothes effectively, where to position it, which settings work best, how long drying takes, and what to look for when choosing one.

Does a Dehumidifier Help Dry Clothes?

Yes—and the reason comes down to how evaporation works. When wet clothes hang indoors, they release moisture into the surrounding air. As that moisture accumulates, the air becomes more humid, and evaporation slows down. The wetter the air, the harder it is for fabric to release more water.

A dehumidifier breaks this cycle. It pulls humid air through its system, removes the water vapor, and returns drier air to the room. This moisture removal process is what allows a dehumidifier to keep improving drying conditions even after the room becomes humid. Because the air around your laundry stays drier, evaporation from the fabric continues at a steadier rate.

Beyond faster drying, using a laundry dehumidifier also helps reduce condensation on windows and walls—a common issue when drying clothes indoors during colder months. It can also help prevent the musty odors that build up when damp air lingers in a poorly ventilated space.

This makes a dehumidifier particularly useful for drying clothes indoors during winter, in apartments without outdoor drying space, in dedicated laundry rooms, and in homes that don't have access to a tumble dryer.

How to Use a Dehumidifier to Dry Clothes

Getting the most from a dehumidifier for drying laundry involves more than just switching it on. The steps below will help you create the right conditions for faster, more efficient drying.

1. Use a High Spin Speed First

Before hanging your laundry, run the washing machine on the highest spin speed the fabric allows. The more water the spin cycle removes, the less work the dehumidifier has to do. This can meaningfully reduce overall drying time.

2. Spread Clothes Out on a Drying Rack

Hang garments with space between them. Overlapping fabric traps moisture and blocks airflow, which slows drying significantly. A clothes drying rack or drying rack that lets air reach all surfaces works better than hanging multiple items on a single hook.

3. Choose a Small, Closed Room

A laundry room, spare bedroom, or any small room that can be closed off is ideal. Smaller spaces allow the dehumidifier to reduce the room's humidity more quickly and maintain a drier environment throughout the drying process.

4. Close the Doors and Windows

Keep the room sealed while the dehumidifier is running. Open doors and windows allow humid air from the rest of your home—or from outside—to enter, making the dehumidifier work harder and slowing down the drying process.

5. Position the Dehumidifier Near the Laundry

Place the unit close to the drying rack, but not directly underneath dripping clothes. Positioning the dehumidifier nearby allows it to capture moisture efficiently as it evaporates from the fabric. Most manufacturers specify minimum clearance requirements in their manuals—follow these to ensure proper airflow around the unit.

6. Use Laundry Mode or a High Fan Setting

If your dehumidifier has a dedicated laundry mode or clothes-drying mode, use it. This setting is designed to handle the elevated moisture load that wet laundry produces. If your unit doesn't have this feature, select a higher fan speed or continuous operation mode. Refer to your model's manual, as the best setting varies between units.

7. Rotate Thick Items if Needed

Thick fabrics—towels, denim, hooded sweatshirts, bedding—retain moisture longer than lighter garments. Turning or repositioning these items partway through can help expose damp areas to more airflow and allow more even drying.

Should You Use a Fan With a Dehumidifier?

Using a fan alongside a dehumidifier can improve drying results, but the two serve different functions.

A dehumidifier removes moisture from the air. A fan or air circulator moves air across the surface of wet fabric, increasing the rate at which moisture evaporates from the clothing. Together, they can dry laundry faster than using a dehumidifier alone with still air.

A fan on its own cannot remove moisture from a room. It speeds up evaporation from the fabric, but that moisture still ends up in the air—it just gets there faster. Without a dehumidifier, the room's humidity can still rise to a point where drying slows.

When combining both, position the fan so it moves air through the gaps between hanging garments rather than blowing directly into the dehumidifier's air intake. This encourages even air movement across the laundry without interfering with the unit's operation.

A small, quiet desk fan or air circulator is usually sufficient. You don't need a high-powered fan—consistent airflow across the drying rack matters more than air speed.

What Is the Best Dehumidifier Setting for Drying Clothes?

The right setting depends on your specific model, but these are the most relevant options to understand.

Laundry mode / clothes-drying mode: Many modern dehumidifiers include a dedicated laundry setting. This mode typically runs the fan at a higher speed and keeps the compressor or desiccant system operating continuously to handle the large amount of moisture wet laundry releases. The exact behavior varies by brand and model, so check your manual for details.

Continuous mode: On units without a laundry mode, continuous operation keeps the dehumidifier running regardless of the current humidity level. This is useful when there's a large moisture load in the room, as it prevents the unit from cycling off before the laundry is fully dry.

Higher fan speed: A higher fan setting draws more air through the unit and increases the rate at which the dehumidifier can process humid air. Most laundry-focused drying benefits from the higher fan speed setting.

Humidistat / RH control: Some units allow you to set a target relative humidity. While this can be useful for general humidity management, a fixed RH target may cause the unit to cycle off before laundry is fully dry. If you're using the humidistat during a laundry-drying session, be aware that the ideal target varies based on room conditions and load size.

How Long Does It Take to Dry Clothes With a Dehumidifier?

There is no single answer that applies to all situations. Drying time depends on several variables working together, and committing to a specific number of hours can be misleading.

The main factors that affect drying time include:

• Spin speed: Higher spin speeds leave less residual moisture in the fabric
• Load size: More clothing means more total moisture to remove
• Fabric thickness: Thin cotton dries faster than denim, towels, or fleece
• Room temperature: Warmer rooms support faster evaporation
• Starting humidity: A room with high ambient humidity takes longer to bring down to a drying-friendly level
• Room size: Smaller rooms allow the dehumidifier to lower humidity more quickly
• Doors and windows: An open or unsealed room allows humid air to re-enter
• Dehumidifier capacity: A unit matched to the room size will work more efficiently
• Air circulation: Adding a fan can reduce drying time noticeably

As a general guide, lightweight garments like t-shirts and underwear will dry considerably faster than thick items like jeans, hooded sweatshirts, or bed sheets. Drying a full load in a small closed room with an appropriately sized dehumidifier and a fan running will typically yield better results than drying the same load in an open living area without air circulation.

How to Choose a Dehumidifier for Drying Laundry

Not all dehumidifiers perform equally well for indoor clothes drying. These are the most important factors to evaluate.

Extraction Capacity and Room Size

Extraction capacity is measured in liters per day (L/day) or pints per day, but this figure alone doesn't tell you everything. Manufacturers test under specific temperature and humidity conditions that may not reflect your actual laundry room environment. Room size, humidity level, and moisture load all affect dehumidifier sizing. See our guide on how to choose a dehumidifier for a more detailed sizing breakdown.

Compressor vs. Desiccant

These are the two main technologies used in household dehumidifiers, and each suits different conditions.

Compressor dehumidifiers cool the air over refrigerant coils to condense moisture. They tend to perform well in warmer indoor environments (generally above 15°C / 59°F) and are a common choice for living areas and laundry rooms in temperate climates. Performance may decrease at lower temperatures.

Desiccant dehumidifiers use a moisture-absorbing material to extract water from the air. They can maintain effective extraction across a wider temperature range, including cooler spaces. They also tend to discharge warmer air, which may slightly benefit drying in cold rooms. Energy consumption and heat output vary by model.

Features Worth Looking For

When evaluating specific units, these features are relevant for laundry drying:

• Laundry mode — purpose-built for high-moisture drying scenarios
• Fan speed settings — more control over airflow
• Operating temperature range — important for garages, utility rooms, or unheated spaces
• Humidistat — allows automated humidity management
• Continuous drainage option — useful for long drying sessions without manual tank emptying
• Tank capacity — a larger tank requires less frequent emptying
• Auto shutoff — prevents overflow if continuous drainage isn't set up
• Timer — helpful for scheduling operation
• Noise level — relevant if the unit runs overnight or in a living space
• Portability — wheels or handles make it easier to move between rooms

Dehumidifier vs. Tumble Dryer for Drying Clothes

Both options can dry clothes indoors, but they work differently and suit different situations.

Running costs depend on the wattage of the specific units, how long each is in operation, and your local electricity rate—so broad claims about which is cheaper don't apply universally. If your priority is fabric protection or you're dealing with a condensation problem in your home, a dehumidifier combined with a drying rack addresses both at once. If speed and convenience are the main concerns, a tumble dryer will usually be faster.

Safety Tips When Drying Clothes With a Dehumidifier

Used correctly, a dehumidifier is safe for indoor laundry drying. A few precautions are worth following.

• Never block the air intake or outlet. Restricted airflow reduces efficiency and can cause the unit to overheat.
• Do not hang dripping clothes directly above the unit. Water dripping into the dehumidifier can damage internal components and create a safety hazard.
• Keep the unit away from standing water and splashes. Position it on a stable, dry surface with adequate clearance from walls and furniture as specified in the manual.
• Follow the manufacturer's recommended clearances. Placing the unit too close to walls or other objects limits airflow.
• Use appropriate electrical connections. Avoid overloaded extension cords and use only setups suitable for the unit's power draw. Check your manual for guidance.
• Empty the water tank regularly, or set up continuous drainage. A full tank will trigger auto shutoff, interrupting the drying cycle.
• Operate within the rated temperature range. Running a unit outside its specified range can affect performance and longevity.

It's also important to recognize what a dehumidifier cannot do. It manages airborne moisture—it cannot fix plumbing leaks, structural damp, or an established mold problem. If you notice persistent mold, water intrusion, or rising damp, those issues require separate assessment and repair.

FAQs About Using a Dehumidifier for Drying Clothes

Can a dehumidifier dry clothes indoors?

Yes. A dehumidifier removes moisture from the air, which lowers the room's relative humidity and allows wet fabric to continue releasing water vapor. Combined with a clothes drying rack and a closed room, a dehumidifier can dry clothes indoors without a tumble dryer.

Should I close the windows when drying clothes with a dehumidifier?

Yes. Closing doors and windows prevents humid air from entering the room, which allows the dehumidifier to lower the room's humidity more quickly and maintain drier conditions throughout the drying process.

How close should a dehumidifier be to clothes?

Position the dehumidifier close enough to capture evaporating moisture—typically within the same area as the clothes drying rack—but not directly beneath dripping garments. Follow the clearance requirements in your unit's manual to ensure adequate airflow around the machine.

Is a compressor or desiccant dehumidifier better for drying clothes?

It depends on where you're drying. Compressor dehumidifiers generally work well in warmer indoor spaces such as heated laundry rooms. Desiccant dehumidifiers can handle a wider temperature range, which may make them more suitable for cooler utility rooms or garages. Check the operating temperature range of any unit you're considering.

Can I use a dehumidifier to dry clothes in a cold garage?

A compressor dehumidifier's extraction capacity may drop significantly in cold temperatures. A desiccant dehumidifier is generally more effective in unheated or cold spaces. Check the unit's rated operating temperature range before using it in a cold garage, as some units are not designed to run in low-temperature environments.
