If you're wondering how to get rid of mould in a poorly ventilated room, or trying to combat excess moisture or humidity inside the home, then a dehumidifier can be a useful tool in your arsenal. The EcoAir DD1 Simple MK3 Dehumidifier can extract up to 7.5 litres of moisture per day in cold temperatures as low as 1ºc, so it's a very useful option for conservatorys, basements or garages that don't have dedicated heating, as well as unheated rooms in the home during winter months. The cheapest and smallest dehumidifiers on the market can often only extract 0.5L of water from the air per day – in many cases even less – but larger and more powerful dehumidifiers can extract up to 25L per day which can make a huge difference to your home's health if you struggle with damp issues and condensation.

Whilst this dehumidifier doesn't offer a specific laundry drying function, we still found it helpful at drying wet washing, although it took longer to do so than the MeacoDry Arete One Dehumidifier or Pro Breeze 20L Premium Dehumidifier with Special Laundry Mode which both offer a speedy dedicated laundry-drying boost mode. 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. 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.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. The brand new Arete range of compressor dehumidifiers are the latest innovation in the line of ultra-quiet dehumidifies from Meaco.

However, thePro Breeze 20L Premium Dehumidifier does win on price, coming in a fair bit cheaper than the MeacoDry Arete One.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. Despite its compact size, this dehumidifier is also heavy. And noisy. We also didn’t find it that much help with drying clothes, although it did a good job of managing general damp and reducing condensation and mould on windows and walls. Most dehumidifiers are noisy, averaging decibel levels of between 34-48dB. That's because they draw in air via a fan and then use a compressor and refrigerant to cool and condense the air to extract the moisture from it. The only quieter dehumidifiers I've come across are Peltier models, like the Pro Breeze 1500ml Mini Dehumidifier. However, Peltier dehumidifiers are far less powerful than compressor dehumidifiers. For comparison, as I discovered in my Pro Breeze 1500ml Mini Dehumidifier review, this Peltier model can only extract 0.5L of moisture from the air per day, compared to the MeacoDry Arete One range which can extract 10, 12, 20, or 25L of moisture per day! Portability That said, this dehumidifier can also act as an air purifier, so there is an optional HEPA filter that you can fit into the dehumidifier. I’d recommend using it as this filter can help to clean the air whilst the dehumidifier is working.Bonus!
