By Manette Kaisershot

Discover the best dehumidifier brands with our test results plus our survey of dehumidifier owners.

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.

Thanks to our years of in-depth dehumidifier lab tests, combined with surveying hundreds of owners, we can reveal the brands that produce the best, most reliable dehumidifiers. And those that produce the worst.

We asked our members about the most common faults they experienced with their dehumidifiers – problems ranged from leaking to unexplained malfunctions. 

We also discovered that 24% of machines from the least reliable dehumidifier brand in our survey experienced some kind of problem in the first five years. By contrast, only 5% of those who bought from the the most reliable brand had problems. 

To make sure you don't buy a dehumidifier that's more likely to develop a fault, we've combined our testing with the findings of our owner surveys to reveal all about dehumidifier brands.

Dehumidifier brands rated

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 are best off avoiding.

For each brand, we tell you:

  • Average test score – based on all dehumidifiers we have tested from 2012 to 2017.
  • How reliable it is – we ask dehumidifier owners how and when their machines broke, so we can estimate 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 quickly discover the dehumidifier brands that are loved, and loathed, by their owners.
  • 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, DimplexEbac and Meaco.

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

How to choose the best dehumidifier

An excellent dehumidifier is one that tackles damp and high humidity with ease, and doesn't make too much noise or use too much energy while doing it. It will also last over time and is one that you’d recommend to friends and family. At Which?, we study trends in our test results which reveal the brands that consistently produce models that can be relied on to keep excess moisture in hand. 

Some dehumidifier brands do very well in our tests, and have exceptionally good reliability scores and customer satisfaction. Others don't do as well in our tests and have been rated less highly my customers. If you're interested in a dehumidifier, check out our dehumidifier reviews.

There is one dehumidifier brand that has a Best Buy model, but the brand's dehumidifiers have a tendency to experience faults over time and are the most likely to experience a leak. You may want to avoid this brand's machines and opt for one that is more likely to keep the water away from your floors. 

Are dehumidifiers generally reliable?

We found that, on average, 82% of dehumidifiers remain fault-free for six years. The brand that tops the table for reliability, though, had 92% of its machines remain fault-free for six years. By comparison, the least reliable dehumidifer brand had 72% of its machines staying fault-free for six years. 

Dehumidifiers topped the charts in our survey for customer satisfaction and are, overall, highly rated for their reliability. Our 2017 small domestic appliance survey asked over 5,000 Which? members about the reliability of their kettles, toasters, coffee machines, irons and many other household items.  

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 dehumidifiers brand’s reliability when compared with other dehumidifier brands.
