Updated 7 December 2025 Garden Gear Guide guide for UK homes

As UK homeowners, we often find ourselves battling dampness, especially during the colder months. While dehumidifiers are often suggested as a solution, various myths can cloud our understanding of their true function. This guide will help you navigate these misconceptions, particularly when it comes to drying laundry indoors without creating an uncomfortable humidity-filled environment.

Understanding the role of dehumidifiers can be essential not just for your home’s comfort, but also for maintaining a healthy living space. Let us debunk some common myths and provide you with practical advice on using dehumidifiers effectively.

Myth 1: Dehumidifiers Are Only for Damp Problems

Many people believe that dehumidifiers are only necessary if you have visible damp problems. However, this is not true. Dehumidifiers can be beneficial even in homes that do not show obvious signs of dampness.

Here are some scenarios where a dehumidifier can be helpful:

  • When drying laundry indoors.
  • In areas prone to condensation, such as bathrooms and kitchens.
  • During periods of high humidity, even if there are no visible damp spots.

By managing humidity levels proactively, you can prevent future damp issues from arising, saving you money and hassle in the long run.

Myth 2: Dehumidifiers Will Make Your Home Too Dry

Some homeowners worry that using a dehumidifier will lead to excessively dry air, which can harm their health. While it is true that very low humidity levels can be uncomfortable, modern dehumidifiers often come with built-in hygrometers that allow you to set and maintain your desired humidity level.

The ideal indoor humidity level is generally around 40% to 60%. Here are some benefits of maintaining this range:

  • Reduces the risk of mould growth.
  • Improves air quality and comfort.
  • Helps preserve furniture and belongings.

By using a dehumidifier wisely, you can avoid overly dry conditions while effectively managing humidity.

Myth 3: You Can Dry Laundry Easily Without a Dehumidifier

Another common myth is that you can dry laundry indoors without any assistance, simply by opening windows or using a fan. While these methods can help, they often do not address the underlying humidity issues.

When clothes dry, they release moisture into the air, which can lead to increased humidity levels. This can create a cycle where your home becomes more humid, making it harder for clothes to dry. Here are some reasons to consider a dehumidifier:

  • It reduces overall humidity, allowing clothes to dry faster.
  • It prevents condensation on walls and windows.
  • It minimises the risk of mould developing on wet clothing.

Using a dehumidifier while drying laundry indoors can make a significant difference.

Myth 4: Dehumidifiers Are Noisy and Distracting

Many people avoid using dehumidifiers due to concerns about noise. While older models may have been quite loud, newer dehumidifiers are designed to operate quietly.

Here are some features of modern dehumidifiers:

  • Quiet operation, making them suitable for bedrooms and living areas.
  • Energy-efficient models that save on electricity costs.
  • Compact designs that fit into various spaces without being obtrusive.

With advancements in technology, you can now find dehumidifiers that work effectively without disturbing your daily life.

Myth 5: Using a Dehumidifier Is Expensive

Cost concerns often deter homeowners from investing in a dehumidifier. While there is an upfront cost, it is essential to consider the long-term savings associated with preventing damp-related issues.

Here are some potential savings:

  • Reduced risk of mould growth, which can lead to costly repairs.
  • Lower energy bills, as a dehumidifier can make heating more efficient.
  • Extended lifespan of furniture and belongings due to reduced humidity.

When viewed as a long-term investment, a dehumidifier can be cost-effective.

Myth 6: Dehumidifiers Are Only for Large Spaces

Some people believe that dehumidifiers are only effective in large spaces, but this is a misconception. There are various models available that cater to different room sizes.

Here are options based on room size:

  • Small dehumidifiers for bathrooms and bedrooms.
  • Medium units for living rooms or kitchens.
  • Large models for basements and open-plan areas.

Choosing the right size ensures that you will effectively manage humidity levels in any space.

Myth 7: You Should Keep Windows Open When Using a Dehumidifier

Many believe that keeping windows open while using a dehumidifier will help it work better. However, this can often lead to the opposite effect.

Here’s why:

  • Open windows can introduce more humid air from outside.
  • It may cause the dehumidifier to work harder, increasing energy usage.
  • Closed windows help maintain a controlled environment for efficient moisture removal.

For the best results, it is usually more effective to keep windows closed while the dehumidifier is in operation.
