It's also important not to confuse the extraction rate with a dehumidifiers water tank capacity. As both are generally measured in litres or millilitres this can sometimes cause confusion. 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

First up, it's worth making clear that this small dehumidifier has a low extraction rate compared to many others on our list. The ProBreeze 1500ml Mini Dehumidifier can extract just 0.5L of moisture from the air per day. For comparison, the lowest extraction rate offered within the MeacoDry Arete One range is 10L of moisture extraction per day. And, whilst this Russell Hobbs number is cheaper upfront, running costs are higher, with the 20L dehumidifier using 440W of energy compared to Meaco's 20L Arete One which uses 216W on average. Plus, the Arete One offers a built-in air purifier which this model does not. 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. It’s the setting with the highest ventilation speed and dehumidifying capacity. In my testing, I found it to really work. I don’t struggle too badly with mould in winter but I do find it difficult to dry clothes (I’m a little too stoic about not switching on the heating). With this DeLonghi dehumidifier sat next to my standard, non-heated clothes airer, my washing dried within a few hours, including a pair of jeans and a hoodie.The Woods MDK11 domestic dehumidifier is ideal for use in many different rooms at home. They are suitable for bathrooms, kitchens, bedrooms, living rooms. They are excellent units to have in a laundry room or drying room as they will remove excess moisture, speed up drying times, keep the space fresh and prevent the growth of bacteria. The air plate at the top of the unit can also be used to blow-dry your laundry to make your workload easier to manage. The Woods MDK11 is a small, portable dehumidifier which is also effective in smaller office spaces or retail areas. The integrated handle makes it easy to carry around different areas, and it runs exceptionally quietly so that it does not disrupt anyone in the room, whether they are working or are just relaxing. Depending on the application, this portable dehumidifier can be set to run by the relative humidity level, a timer, or continuously. 10 Litres/24 Hours Extraction Capacity Featuring a 1.8-litre integral tank & hose connection So take your time to really understand the sort of product you’re looking for. Think about the sort of features that you need. Which ones are “nice-to-have” and which ones are absolutely critical. If you’re looking for a cheap option then don’t even consider the products that are all signing all dancing because you’ll be paying for features that you don’t need. Choose your retailer wisely Under the old regulations, these sizes were 70, 50 and 30 pints, respectively, and you'll see such numbers with three older models above.

A desiccant dehumidifier differs in that it uses an absorbent material or chemical dessicant to extract moisture from the air. This means they can operate efficiently in lower temperatures, down to just 1°C, and are useful for garages, basements, conservatorys, or unheated rooms in the house over winter. However, they're usually more expensive both upfront and in terms of running costs than a compressor dehumidifier, so unless you're looking to remove damp at cold temperatures you're generally best off with a compressor model. It's also worth considering noise levels and energy consumption before you invest in a dehumidifier. What's the quietest dehumidifier? The tank capacity dictates how much water the water tank of the dehumidifier can hold before it needs emptying. A larger tank capacity – such as the MeacoDry Arete One Dehumidifier's generous 2.5L or 4.8Ltanks – means you won't be emptying it as frequently. Don’t get too excited about this dehumidifier’s smart capabilities. You can connect it to your smartphone or tablet via Bluetooth, but the app is little more than a glorified remote control with only basic scheduling features and no way to integrate with existing air quality meters you might have hooked up. That aside, it’s a well-designed and effective dehumidifier, capable of extracting up to 20 litres per day into a larger-than-average six-litre tank. We found this surprisingly easy to remove from the rear of the machine when full, with a built-in handle for carrying.Airflow Rate Of 185m³/h: This unit has an impressive airflow to draw in large volumes of humid air and remove moisture using the natural process of condensation. It is ideal for spaces of 120² and has a two-speed fan. Just like the larger model, the 10L has a laundry mode to dry your washing, and can double as an air purifier with the bundled HEPA filter inserted – although we found it a little less effective in our air-purifying tests than most dedicated models. As a dehumidifier, it’s hard to fault, working efficiently in small and medium-sized rooms to reduce humidity levels and get rid of mould and moisture. Throw in the intuitive controls and easily removable water tank, and this is the best of the compact options, and ideal for smaller rooms and homes. 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.
