Large water tank: The ample 5.5L water tank conveniently shuts off when full and the ProBreeze comes with a continuous drainage hose that can be inserted directly into a drain if required.

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. 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. Internal Drying: This feature will help prevent mould caused by dampness from forming inside your dehumidifier, allowing for long storage and a long product life cycle. Wifi Smart App Control - The appliance can be set remotely via a special smart phone App. This feature lets you adjust it from work, for example. Costs as little as 24 p/hour to run: Our energy-efficient dehumidifier has been designed to automatically shut off once it has reached your desired humidity level.

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. Our old home, with its single-glazed windows and substantial granite walls, has long been a bastion for dampness. Over the years we've haemorrhaged money on cheap dehumidifiers and damp absorbers to no avail. 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.

Lastly, there's extra functionality to consider. The best dehumidifiers you can buy offer a Smart mode. That means you can leave the dehumidifier running and its sensors will detect the humidity levels and switch the machine on and off to keep humidity within your desired range. That saves energy (and money) as the appliance isn't running if it doesn't need to be. A dehumidifier's extraction rate is an average of how much moisture it can remove from the air during a given timeframe. Most commonly this is measured in litres per day, so an extraction rate of 10L/per day means the dehumidifier should be able to extract 10 litres of moisture within 24 hours if running continuously. In practice, this also depends on the humidity levels of the room, and the ambient temperature. Drainage - There are two ways of managing the water extracted by the dehumidifier. It can go in the 3 litre water tank which can then be emptied when it's full. It can also be connected to the included drainage tube, allowing for uninterrupted and continuous water drainage. Note that the appliance automatically shuts off when the tank is full.

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.

Cost-effective operation: The ProBreeze is an energy-efficient workhorse, extracting up to 20 litres of water daily, costing as little as 14p/hour to run.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. If you want a dehumidifier of a similar power and price point, the slightly more expensive ProBreeze 1500ml Mini Dehumidifier remains our best budget buy, offering a better extraction rate of 0.5L and a larger 1.5L water tank, which means you won’t be emptying it quite so frequently. That said, the ProBreeze 1500ml Mini Dehumidifier is also larger in size, measuring H30 x W22 x D16cm compared to the Russell Hobbs' H22 x W14 x D14cm frame. And, the ProBreeze 1500ml is twice the weight, weighing in at 1.85kg. With its promise of premium quality, I was keen to see what features the ProBreeze has. Overall, I'd say that the spec of this product really does hold water (and not just in the literal sense). Amongst its many functions, the ProBreeze has the following features: Litres Per Day: Removes up to 30L of water per day with low energy consumption in temperatures between 5°C and 32°C.

Automatic Humidity Sensor: Set your desired room humidity between 35%-85%. Once this level is reached, the compressor will turn off to conserve energy.

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. All that said, the Russell Hobbs RHDH2002 20L dehumidifier still impressed our review team during testing. So, if you’re looking for a powerful dehumidifier with a cheaper upfront cost, the Russell Hobbs RHDH2002 20L is well worth considering.
