Struggling with windows covered in condensation every morning, your wardrobe smelling musty, or and spotted black mould starting to take hold in your home? With many of us cutting back on our heating bills, the conditions are just right for damp to take hold.

But you can fight back! We'll walk you through how dehumidifiers can be used to remove damp and tackle mould growth below.

Types of dehumidifiers

Buying a dehumidifier might seem simple, but get the wrong type and it's not going to be much good for you. Here's a quick breakdown:

  • Refrigerant dehumidifiers: They suck in warm, humid air and condense it on a cool surface to extract moisture. Ideal for rooms above 15C.
  • Desiccant dehumidifiers: They use an absorbent material to extract moisture from the air. Ideal for cold areas under 15C, like garages.
  • Moisture absorbers: Effectively disposable dehumidifiers, they use crystals that dissolve in moist air to form water drops.

We've put together this essential guide to dehumidifiers that tells you more about the different types and the features to look out for.

How to prevent mould at home

Dehumidifiers are great for preventing mould as it likes to grow where there's moist air, but you won't be able to remove it using a dehumidifier alone. First you'll need to use a mould-removing cleaning product.

Now you've got rid of it, it's time to get that humidity down!

Window condensation

When warm wet air hits a cold window (particularly during winter), you get lots of condensation. That can contribute to the damp and mould, so we need to capture the moisture before it spreads.

Get your hands on some moisture absorbers! These little disposable dehumidifiers use crystals that react with the moisture in the air, causing them to dissolve and create water droplets that fall into the container.

An added bonus - they're massively more affordable than an electric dehumidifier, and won't add to your energy bills!

Musky wardrobes

Keep your clothes smelling fresh with moisture absorbers too! Because wardrobes don't get a lot of air circulation, it's an easy place for damp air to fester, leaving fabrics smelling musty and mouldy.

A small dehumidifier at the bottom of your wardrobe will help reduce the moisture and prevent that horrible smell. Why not try a battery-powered moisture absorber with a fan to pull in more damp air.

Everyday use

When it's cold, the last thing you want to do is open your windows to let fresh air in! Another option is to turn up the thermostat, but with today's energy prices that's not ideal either.

That's why we'd recommend getting an electric dehumidifier. Lots of things put moisture into the air in your home - whether it's running a hot shower, cooking, or drying your clothes indoors - but with an electric dehumidifier, simply plug it in, switch it on and leave it to suck the moisture out of the air.
