Updated 1 April 2026 Fresh Dry guide for UK homes

Drying laundry indoors can often lead to an increase in humidity levels, resulting in mould growth and unpleasant musty smells. Using a dehumidifier can be an effective solution to these common indoor issues. This guide will provide you with practical advice on how to use a dehumidifier to dry your laundry indoors while preventing damp-related problems.

We’ll explore the benefits of using a dehumidifier, the best practices for drying your clothes, and how to maintain a healthy indoor environment.

Understanding Humidity and Its Effects

Humidity is the amount of moisture in the air, and it can significantly affect the comfort and health of your home. High humidity levels can lead to:

  • Mould growth on walls, clothing, and furniture
  • Musty odours that are unpleasant and persistent
  • Increased risk of respiratory problems

Drying clothes indoors naturally adds moisture to the air, which can exacerbate these issues. A dehumidifier helps to reduce the humidity levels, making it easier to dry your laundry while also improving air quality.

The Benefits of Using a Dehumidifier for Laundry

Using a dehumidifier when drying laundry indoors has several advantages:

  • Faster Drying Times: A dehumidifier removes moisture from the air, allowing your clothes to dry more quickly.
  • Prevents Mould Growth: By maintaining optimal humidity levels, you reduce the risk of mould and mildew developing on your clothes and in your home.
  • Improved Air Quality: Reducing excess humidity leads to fresher air and can alleviate respiratory issues.
  • Energy Efficiency: Dehumidifiers can be energy-efficient, consuming less power than running a tumble dryer.

Choosing the Right Dehumidifier

When selecting a dehumidifier for drying laundry, consider the following factors:

  • Capacity: Look for a dehumidifier that can handle the moisture output of your laundry. A unit with a capacity of 10-20 litres per day is usually sufficient for household use.
  • Energy Efficiency: Choose models with good energy ratings to save on electricity bills.
  • Portability: Opt for a unit that is easy to move around, especially if you need to reposition it in different rooms.
  • Noisy Operation: Some dehumidifiers can be quite loud; check reviews for noise levels if this is a concern.

How to Use a Dehumidifier for Drying Laundry

Follow these steps to effectively use a dehumidifier for drying your laundry indoors:

  1. Hang Your Laundry: Use a drying rack to hang your clothes in a well-ventilated area. Avoid overcrowding to allow air to circulate freely.
  2. Position the Dehumidifier: Place the dehumidifier close to the drying rack. Ensure it’s in a central location where it can effectively capture the moisture.
  3. Set the Dehumidifier: Turn on the dehumidifier and set it to a humidity level between 40-50%. This range is effective for drying while maintaining comfort.
  4. Check the Water Tank: Regularly check the water tank to ensure it doesn’t overflow. Some models have continuous drainage options if you want to avoid frequent emptying.
  5. Monitor Progress: Keep an eye on the drying process. You may need to adjust the settings based on the weather or room conditions.

By following these steps, you can efficiently dry your laundry while minimising the risk of mould and damp smells.

Maintaining Your Dehumidifier

To ensure your dehumidifier operates effectively, regular maintenance is essential:

  • Clean the Filters: Check and clean the air filters monthly to maintain airflow and efficiency.
  • Empty the Tank: If your unit requires manual emptying, do so regularly to avoid overflow and maintain performance.
  • Inspect for Dust: Wipe down the exterior and check for dust buildup around the vents to ensure optimal operation.

Regular maintenance will extend the lifespan of your dehumidifier and ensure it continues to provide a comfortable indoor environment.

Additional Tips for Drying Laundry Indoors

To enhance the efficiency of drying laundry indoors, consider these additional tips:

  • Use a Fan: Pair your dehumidifier with a fan to improve air circulation and speed up drying times.
  • Open Windows: If the weather permits, open windows to allow fresh air in while using the dehumidifier.
  • Use a Clothes Horse: A clothes horse is great for spreading clothes out, allowing for better air circulation compared to a traditional line.
  • Limit Laundry Loads: Avoid overloading your washing machine to reduce drying time as less moisture will be introduced into the air.

Signs You Need a Dehumidifier

Recognising the signs that you need a dehumidifier can help you combat mould and damp effectively:

  • Visible Mould: If you see mould growth on walls or clothing, it’s a clear indicator of excess moisture.
  • Musty Smells: Persistent musty odours in your home can signal high humidity levels.
  • Condensation: If you notice condensation on windows or walls, your home may benefit from a dehumidifier.
  • Wet Laundry Takes Too Long to Dry: If your clothes remain damp for long periods, it may be due to high indoor humidity.
