Product Information

Some purifiers have a built-in timer. This can be really useful if you want your machine to come on a few hours before you get home, or if you want to turn it off automatically at night. The De'Longhi Tascuigo AriaDry DEX216F is the largest model in the range and able to extract 16L of water from the air per day, and although the tank capacity isn't the largest, at 2.1L it still offers adequate capacity. This multi-purpose appliance also has an air purifier function with a double filtration system that can remove dust and other allergens from the air, plus a dedicated Laundry Drying function. This Russell Hobbs Compact Dehumidifier and Air Purifier is the ideal tool for reducing humidity and minimising the physical signs of damp and condensation in your home office, utility room, or living space. This compact model is suitable for spaces up to 20m²- perfect for medium sized rooms.

You’re more likely to know Acer for its PCs, laptops or monitors, but its foray into air purifiers shows a lot of promise. The Pro P2 is a mid-sized tower – just under 58cm tall – with the top accommodating the fan’s grille, the minimal controls, and a 1.5in square OLED colour screen. The latter gives you the current PM2.5 reading, plus an at-a-glance air quality indicator, with the text turning from green through amber to magenta as it worsens. 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.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. If you have more serious damp issues, then although a dehumidifier can help to reduce the problem and improve the air quality in your home, it won't prevent the damp from occurring in the first place, so it's important to get to the root of the issue. Read our guide to how to get rid of damp for help in identifying the cause of your damp issues, and how to treat them. Spending more will get you something quieter with more power, but this is a decent little purifier for a small lounge, home office or bedroom if you’re working on a similarly sized budget.

The alternative is a Peltier dehumidifier, which, although not specified, is likely the method the Silentnight 39899 600ml Dehumidifier uses. In contrast to a compressor dehumidifier, a Peltier dehumidifier uses a far quieter thermo-electric process to extract moisture from the air. This model is simple to operate thanks to the touch control panel and LED lighting, as well as offering 3 speed settings and a low noise function for complete flexibility. The lightweight 2.8kg body means it’s easy to move from room to room, so you can keep any area fresh and dry. When I tested the laundry function on the Russell Hobbs 20L dehumidifier to dry t-shirts in a small bedroom, it definitely sped up the drying time' said our reviewer. 'The T-shirts closest to the dehumidifier dried in 3 hours, but those further away took aboutdouble that time to completely dry'. How we test Air purifiers use different kinds of filters to do their job – usually, a large, washable, reusable pre-filter to collect bigger particles, plus a finer filter, which is usually a disposable high-efficiency particulate air (HEPA) filter. The length of time this lasts varies, but on average expect it to need replacing every six months (or fewer if you use the machine less). It’s the HEPA filter that catches all the tiny airborne nasties, and these are capable of catching particles as small as 0.3 microns, which is more than three times smaller than a cigarette smoke particle. 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.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. 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. We’re not sure how well that works in practice, but the UA-HD40U-L is impressively efficient at filtering out impurities and very quiet at its automatic and low-power settings. A strip on the top turns from red to orange to green to indicate the current air quality, and there’s a humidity readout so you can monitor humidity levels, although both this and the “ion shower” feature can be turned off if you just want air purification. Well designed and easy to use, this is a great air purifier for smaller rooms.

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. 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. A few high-end units double as humidifiers, managing the moisture in the air to prevent dry air causing irritation to the nose, throat, lips and skin.The sleek and modern unit with navy blue exterior stands out from the crowd in all the right ways, and whilst it doesn't have built-in wheels like most dehumidifiers of this size, the integrated carry handle and mid-weight build make it relatively easy to transport from room to room. If you want a more compact build, then there is also a 12L and 14L model available.
