How do dehumidifiers work?

An electric dehumidifier reduces humidity and prevents mould by filtering moisture out of the air, before recirculating the dry air back into the room. They draw air into the device which is passed through cold coils that attract the moisture and condense it into water. That is then collected in the built-in drip tray so you can pour it away and reduce the overall humidity in your home.

Depending on how much you need to reduce the humidity, you can choose various unit sizes to allow more water collection and get extras like anti-allergy dust filters and HEPA (high-efficiency particulate absorbing) filters for air purification.

Similarly, small and mini desiccant dehumidifiers use moisture-absorbing crystals to tackle condensation. Those crystals attract the moisture in the air, which then binds together and forms larger water droplets that collect in the bottom. Buy a quiet, or even silent, small dehumidifier that prevents mould in harder to reach areas like wardrobes and windowsills.

Are dehumidifiers expensive to run?

Depending on what you need it for, electric dehumidifiers can be costly to run due to the energy demands and usage times, but they can also be essential so it's worth considering whether you want to prioritise performance or energy consumption. If you need to tackle damp and humidity after a leak or flood, an effective dehumidifier is really the only way to effectively prevent mould from taking hold in your home.

If, however, you haven't got the best air circulation in a home or flat and need to prevent the humidity of a warm shower from causing mould and damp in your bathroom, search for low-energy dehumidifiers that you can run regularly without worrying too much about your energy bills. Just use the handy filter search above to select the features you need.

The other alternative, if you just need to help deal with condensation on windows in the colder winter months or prevent a musty smell from taking over your wardrobe, opt for a desiccant dehumidifier that has no running costs. You can buy these small dehumidifiers, put them in place, and let the moisture-absorbing crystals do their thing! You can even get electric models with mini fans for an added boost and you only need to buy batteries to operate them.
