Overall, it's not the most powerful dehumidifier you can buy, and it can't cope with high moisture levels – we found it made little difference when drying wet washing for example. However, it did a great job of clearing condensation on windows and managing moisture levels in a small bedroom when left running overnight. According to learnmetrics.com, a dehumidifier uses between 300 watts and 700 watts of energy per hour, depending on size and efficiency. That’s not much - more than your fridge but less than things like kettles and hair dryers. What's the best dehumidifier to buy? As for energy consumption, you can find out more in our guide to ' How much does it cost to run a dehumidifier?'. However, the easiest way to find out is to compare each dehumidifier's wattage. The higher the number of Watts the appliance requires, the more expensive running costs will be. If you’ve noticed that there is a lot of condensation on your bedroom windows in the morning, it might be time to buy a dehumidifier. During the night, we sweat (a lot more than you might think) and breathe out warm air; this adds to the moisture in our room. However, dehumidifiers can be noisy, especially the compressor type, and with sleep already at a premium, finding one that doesn’t keep you awake is an absolute must! That’s where the Silentnight dehumidifier comes in. As well as saving on laundrette costs, a dehumidifier will save money on heating bills because less moisture means less of a biting chill in the air. You can also save money on products for shifting mould or odours. And that tumble dryer you were thinking of buying? Forget it. A dehumidifier will cost you significantly less.

At night, you can use the Sleep mode which turns off all panel lights and minimises the noise emitted by the unit by lowering the fan speed to the minimum. Things are a bit more complicated than this though. While a dehumidifier is sold with a power rating, that doesn’t mean it uses this power all the time. You won’t need to leave windows open as much, which again makes your home easier to heat. This is especially important during the winter months. There's also plenty of useful functionality on the models. The automatic Smart Humidity Mode works perfectly and is hassle-free, turning the dehumidifier on when moisture-levels rise and automatically shutting the appliance off when the desired humidity is reached so there's no wasted energy or expense.And in our tests, the Arete One reduced moisture levels in damp-prone rooms in a very short period of time.

Compressor dehumidifiers tend to be the most common design available in the UK. They work by drawing air into the dehumidifier via a fan, and then running the air over over cold coils to condense the moisture from it, whereby the condensed water is collected in a water tank.The coils are kept cool by refrigerant which means the unit also needs a compressor built in. The only downside of compressor dehumidifiers is that they need the air to be warm for this process to work. Most will work above 5°C, but they're most efficient at an ambient temperature of around 20°C (depending on the individual model).
