Which dehumidifier brand to buy in 2019

By Christina Woodger

Discover the dehumidifier brands you can rely on. Find out which brands get top marks from our expert testers and from those of you who own them

Put us to the test

Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

We've combined our lab test results with survey data from more than 570 dehumidifier owners to reveal which brands are the best and worst. 

We asked our members about the problems they most commonly faced with their dehumidifiers, including leaking units, leaking water tanks and unexplained faults. 

The brand ranked least reliable following our member survey was also the only dehumidifier brand with a Don't Buy. And – disappointingly – 'complete failure' was the most commonly reported fault from that brand.

How we rate dehumidifier brands 

We’ve pulled together our expert knowledge of dehumidifiers, which is based on years of in-depth research. This means you can easily see which dehumidifier brands are a good bet and which ones you're best off avoiding.

For each brand, we tell you:

  • Average test score – based on all dehumidifiers we have tested from 2012 to 2019.
  • How reliable it is – we ask dehumidifier owners how and when their machines broke down, so we can tell you the average life expectancy for each brand’s machines.
  • How owners rate it – we ask owners if they would recommend their dehumidifier to a friend or family member. We turn this into a percentage score, which means you can see at a glance the dehumidifier brands that are loved by their owners, versus those that cause annoyance.
  • Our overall verdict – we summarise all of our testing and survey data for each brand and give it an overall verdict.

We have ratings for all the major dehumidifier brands, such as DeLonghi, Ebac, Ecoair and Meaco.

Only logged-in Which? members can discover which brands are the best in our table.

Can't see the brand you're interested in? We couldn't report on some brands, as we didn't get enough responses from owners. But you can read our reviews of dehumidifiers from other brands, such as Argos, Blyss, Currys PC World, Dimplex and Vax. Or check out all our dehumidifier reviews.

Are dehumidifiers generally reliable? 

Yes – which is good news. We found that, on average, 93% of dehumidifiers remain fault-free for eight years. 

We did see differences between the brands, though. The most reliable brand had 100% of its machines remain fault-free for eight years. By comparison, the least reliable dehumidifier brand had 85% of its machines staying fault-free for eight years. 

Dehumidifiers are fairly reliable compared with the other household appliances we included in our survey, which included kettles, toasters, coffee machines, irons, microwaves, stand mixers, food processors and blenders. Of course, some of these other products (such as kettles and toasters) really take a hammering, often getting used every day. Dehumidifiers may be used every day – to tackle low-level condensation, for example – or may be used rarely, such as in the event of a flood.   

We calculate our reliability scores based on the proportion of dehumidifiers with problems per brand in our customer survey. The results are weighted so that more serious problems account for more of the score, and we adjust the scores to account for the age of the dehumidifier so that older models don't unfairly influence the score. Our star ratings in the table show a dehumidifier brand’s reliability when compared with other dehumidifier brands. 

 

Common dehumidifier problems 

We also asked our members to tell us which problems they had most commonly experienced with their dehumidifiers.

  • 40% of members' dehumidifiers had stopped working without any obvious reason.
  • 18% experienced problems with the dehumidifier leaking.
  • 10% of members reported that their dehumidifier had frosted up.

Leaking problems include things like a leaky water tank or water leaking from the unit itself. 

Other problems included the auto function or humidistat playing up.

Dehumidifier brands compared 

DeLonghi dehumidifiers

Most DeLonghi dehumidifiers are the refrigerant type, which is the most popular type for occupied homes in the UK. 

We've tested and rated refrigerant dehumidifiers from DeLonghi, ranging in capacity from 10 litres to 16 litres (‘capacity’ here describes the amount of water the manufacturer claims the dehumidifier can pull from the air each day, rather than the capacity of the water tank). Ten to 16 litres should be suitable for a small to medium-sized home.

You'll typically spend between £100 and £200 for DeLonghi dehumidifiers ranging in capacity from 10 to 16 litres.

Read our reviews of the DeLonghi dehumidifiers we’ve tested. 

Dimplex dehumidifiers

Dimplex makes a range of refrigerant dehumidifiers from 10 litres to 20 litres, which suit both smaller and larger homes.

We’ve tested and rated six Dimplex dehumidifiers. Head to our Dimplex dehumidifier reviews to discover how effective they are. 

You should also be aware that Dimplex has recalled several dehumidifiers due to a risk of overheating and catching fire. We have made these models Don’t Buys. 

These models are DXDH10N, DXDH16N, DXDH20N, FTE10, FTE16, FTE20, plus any with serial numbers starting with 501 through to 652.

If you own a Dimplex dehumidifier that was manufactured between 2015 and 2016, you should check its serial number on the product rating plate before continuing to use it. You will need to remove the water tank to do this. 

If your dehumidifier is affected, switch it off at the power socket, unplug it and contact Dimplex on 0800 028 5386. 

Ebac dehumidifiers

Ebac is one of the best-known dehumidifier brands, and there are plenty of Ebac dehumidifiers to choose from. As with the others, Ebac dehumidifiers come in a range of sizes. 

If you want a dehumidifier to work in a large home, you might want to consider one of Ebac’s 21-litre or 25-litre dehumidifiers, which cost about £270 to £290. For small and medium-sized homes, Ebac also makes 15-litre and 18-litre dehumidifiers, costing £170 to £250. 

Many Ebac dehumidifiers come with ‘Smart Control’ technology, designed to replace the normal humidistat by constantly monitoring the temperature as well as the humidity in your home to maintain a good humidity level, and, according to Ebac, save you money. 

Pricier Ebac dehumidifiers have a extra features, such as LED controls or a more stylish design. Dehumidifiers in Ebac’s Powerdri range are designed for drying plaster and for use in outbuildings, garages and flood-damaged conditions, where the damp level is high. 

Make sure you check out our Ebac dehumidifier reviews before parting with your cash.

EcoAir dehumidifiers

EcoAir makes a wide range of dehumidifiers, including 7-litre, 10-litre and 12-litre models. Ecoair’s dehumidifiers are among the most lightweight we’ve tested, which is ideal if you live alone and anticipate needing to move your dehumidifier around your home frequently.

Dehumidifiers in the Classic range come with more features, while the Simple range is more basic (and cheaper). The Ecoair dehumidifiers we’ve tested range from about £110 to £190. 

The majority of Ecoair dehumidifiers are desiccant models, but Ecoair has some refrigerant options too.

Meaco dehumidifiers

Meaco may not be as well known as DeLonghi, but it specialises in dehumidifiers, air purifiers and air conditioners. You might spend between around £115 and £300 on a Meaco dehumidifier.

If you’re looking for a dehumidifier for a larger home, consider either the Meaco Platinum 20L Low Energy or the Meaco 25L Low Energy Dehumididryer. If you're looking for a model for a smaller home, consider the Meaco 10L Small Home, the Meaco DD8L or the Meaco DD8L Zambezi. 

Meaco dehumidifiers fall into two ranges: standard, such as the DD8L; and premium, such as the Low Energy models, which Meaco says will save you money over time. 

Check out our eight Meaco dehumidifier reviews to see whether one of them could be the perfect choice for you.
