As such operation couldn't be easier, however, I did miss having a little more functionality during testing. Performance If you're looking for the best dehumidifier for the bedroom, then, in our opinion, it's all about finding a dehumidifier with low noise volume, and the Silentnight 39899 600ml Dehumidifier is one of the quietest dehumidifiers we've tested.

The Pro Breeze is great if you’ve got a smaller space and you want something that doesn’t cost a lot to run,” says expert Kandola. “It’s probably about a penny an hour.”

Dehumidifier Size Recommendation Chart

Energy use: The one thing that sets this mini dehumidifier apart from its competition is its energy use. At 100W, this compact dehumidifier uses double the energy of the other low cost dehumidifiers in our round-up. In reality, it’s probably a little too powerful for my needs, instead I’d recommend it to anyone with large, open-plan rooms in their houses or a big house with open doors, where it can sit in a hallway. While the power of 290 Watts means it only costs around 8p per hour, there are still lower energy options on this list that anyone with a smaller house or flat should consider. Unlike a compressor dehumidifier that passes air over a cold coil to condense the water from it, a desiccant dehumidifier uses a 'desiccant chemical' to absorb the moisture from the air. As a result, desiccant dehumidifiers are the best option for rooms that are likely to fall below 15°c, as at lower temperatures compressor and Peltier models can struggle to work efficiently.

However, it's not perfect. A powerful extraction rate of 20L, plus that Laundry boost mode, means higher running costs. This dehumidifier guzzles 440W of energy compared to the 20L MeacoDry Arete One's 216W. What the Pro Breeze 20L Premium does offer is a more generous water tank of 5.5L compared to the 20L MeacoDry Arete One's 4.8L, although in practice we didn't find ourselves emptying the MeacoDry that much more frequently. The recommended humidity for your home is 40-60 per cent in the summer months and between 30-50 per cent in the winter. You can measure it with a hygrometer (a humidity gauge - they’re not expensive). If it goes over 70 per cent, you run the risk of condensation, damp, mould, fungi and bacteria. That’s when you need a dehumidifier. Which is better, a compressor or desiccant dehumidifier? Noise levels: This is where the Silentnight 39899 really comes into its own. When switched on, its operating noise levels are just 25dBA, and when I say it’s whisper quiet, I mean it. I couldn't hear this dehumidifier whilst it was running at all. That makes it perfect for anywhere you want to maintain peace and quiet, and thanks to its green light, I thought it made the perfect addition to a kids bedroom, doubling up as a nightlight when its running. The Pro Breeze 12L Low Energy Dehumidifier is a popular choice thanks to its relatively low price point that makes it one of the best value compressor dehumidifiers you can buy. Clearly, setting a lower fan speed will reduce the noise level but that also limits what the dehumidifier can do. When manufacturers quote a noise level this refers to the noise level at the lowest speed setting, so in practice the dehumidifier will often be louder.

How to Choose a Size

Choosing the right size or capacity is vital when buying a dehumidifier. Unfortunately, many people are confused by what size actually means and how it affects water extraction. In this article, we’ll take you through the basics of size to help you choose the best dehumidifier for your home. What is Dehumidifier Size? Interestingly, ProBreeze measures this units noise levels as 40dB – fairly high compared to many dehumidifiers we've tested – however, it's the type of noise as well as the volume that dictates how intrusive an appliance's noise is, and I found the ProBreeze 1500ml Mini dehumidifier particularly quiet in comparison to most. Portability

Overall, this is a best-in-class dehumidifier that does a fantastic job of extracting moisture from the home and is one of the best dehumidifier for drying washing fast. Noise levels: The official specifications say that this dehumidifier is 37dBA but I barely heard it. I didn’t even realise it was on when I was in the room. It runs so quietly, you occasionally hear the odd drip as the water hits the already collected water in the tray but that’s about it. It’s ideal for use when you’re working or overnight as it won’t disturb the peace. These interior dehumidifiers hold 500ml and will last for up to 60 days depending on temperature and condition. Despite its compact size, this dehumidifier effectively removes moisture in the air within a 15-square-metre space—the model measure 5.1D x 15.6W x 21.8H centimetres. If you’ve ever had reason to ask yourself ‘what is the best dehumidifier?’ it was probably with a sense of desperation over mould in your bathroom that just won’t shift, or window condensation forever puddling on the sills. Humidity can be a real problem. A dehumidifier is your best defence.If you’re looking for a dehumidifier that can clear moisture in a larger space or deal with significant damp levels within the home, then you need a dehumidifier with a high extraction rate. Compressors are generally efficient at room temperature, but they can’t handle the winter cold so well. If the temperature drops below three or four centigrade, they will tend to stop working. That’s not the case with desiccants, although they can be more expensive to run. How to use a dehumidifier 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. The beauty with Peltier dehumidifiers is that this thermo-electric technology gives way to 2 great advantages. These include 1) whisper-quiet operation and 2) energy-saving functionality (when used on a small scale like this).
