Multiply the wattage by the number of hours you plan to run the dehumidifier and divide by 1,000 to convert to kWh. If damp or condensation in your home is more widespread, then a dehumidifier is a good investment. Dehumidifiers are electric appliances that can be moved around the house to help remove excess moisture from the air. They draw air in through a vent, which is then passed through a filtering system Water vapour from the air condenses into water droplets, which collect in a removable compartment. The air is then recirculated around the room. Less moisture in the air will result in less condensation on walls and windows, helping to alleviate damp and mould. To take advantage of this great offer just simply add the warranty extension you want and we'll do the rest.

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. That extraction level may not sound like much, and this certainly isn't a dehumidifier that can cope with large damp problems or help to dry washing. But, in practice, our tests found it worked well when left running in the bedroom overnight in our tester's single-glazed Victorian terrace. It reduced the build up of condensation around windows in the morning, and the air in general also felt fresher whenever it was running. It also did really well to help eliminate steam and fumes in the kitchen whilst cooking. Position your device in the dampest room, and then when it’s reached the desired humidity move it to the next space. When you’ve finished, place it in a central location with all room doors slightly open to capture the remaining moisture. We recommended leaving a six-inch gap between your dehumidifier and any walls or furniture.If you have a lot of laundry you need to dry indoors over the winter months, then we think thePro Breeze 20L Premium Dehumidifier with Special Laundry Modeis the best dehumidifier for drying clothes fast. 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. It’s bad for you because bugs and mould love high humidity levels. Dust mites and mould spores thrive and can trigger allergies, skin irritation and respiratory problems such as asthma. Moods and general wellness can also be affected. Desiccant dehumidifiers tend to have lower listed capacities than refrigerant. This doesn’t mean they should be ignored though, as they are far more effective at removing water in cooler conditions. For example, at temperatures of 10 degrees Celsius or below, a desiccant dehumidifier with an 8 litre/day capacity may extract significantly more water than a refrigerant model with a higher listed capacity.

The level of moisture in the environment. This is a more subjective measure, unless you use a humidity monitor. But you should have an idea of how damp a space is by noticing where moisture is accumulating. Key specs – Dehumidifier type: Desiccant; Tank size: 2l; Extraction rate: 6 litres per day; Dimensions: 48.5 x 29 x 17.5cm; Weight: 6kg; Warranty: 2 years Dehumidifiers range in capacity. The smallest start at around 500ml per day. These models are often cheap but are only suitable for single rooms, boats or caravans. Don’t let moisture in the air put a dampener on the state of your home. Homebase supplies a variety of moisture absorbers, dehumidifiers and air purifiers from the biggest brands to keep out musty smells, polluting particles and potential damage from mould, damp and mildew. That doesn’t mean capacity should be ignored though. As a general rule, bigger capacity dehumidifiers can deal with larger spaces and higher levels of moisture.

It also offers Smart App controls, which means you can connect it to WiFi and operate it remotely via the Pro Breeze App or connect to Alexa or similar voice-activated devices. It has a decent-sized water tank capacity of 4L, and an automatic humidity sensor which means you can set your desired humidity level, switch it on, and just let it do its thing.

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. So, if you’re after the smallest dehumidifier on the market, we think the Russell Hobbs RHDH1061G wins the accolade of best small dehumidifier, with good all round performance for its size housed in one of the smallest builds on the market – along as you don't expect too much from that 0.3L extraction rate. Keep in mind that these numbers are only a guide. As we’ve discussed, there are other factors that affect the effectiveness of a dehumidifier, including the type (desiccant models tend to have lower listed capacities but are more effective in cooler conditions) and temperature of the environment. Plus, the MeacoDry Arete One dehumidifier'sSmart Laundrymodeworks brilliantly for drying washing indoors – wet laundry was dry in hours rather than the days it can usually take in the draughty Victorian terrace we tested the unit in.The Princess isn’t as quiet as Meaco’s Arete models, but you can live with the 46dB it puts out at its highest fan setting, or the 40dB noise levels at low. It also has a useful laundry drying feature that makes the most of the vertical swing on the air output and the powerful fan. It’s simple to control, either through the app or via the built-in controls, and you can keep an eye on the current humidity level through a subtle “hidden” digital display on the front. Rival dehumidifiers have the edge on noise and performance, but the Princess gives you a great set of features at a very reasonable price.

It’s probably obvious that the larger the room(s), the greater capacity you’ll need. Rooms with severe damp problems also require larger capacities. Signs of severe damp include stains on walls, condensations on walls and, in the worst cases, wet floors. During our testing process we found it really easy to use and operate, and our reviewer loved the Smart App connectivity (something few dehumidifiers offer) as it gave her a lot more control over how she could use the machine, saying 'the in-App experience is fantastic, the menus are really clear, and changing the settings is simple'.The DD8L Zambezi is an example of a desiccant dehumidifier. These models often have lower capacities but work best in cooler environments. On the other hand, refrigerant models usually have a higher maximum extraction rate in ideal conditions (high humidity and temperature). What Sizes are Available?
