Complete failures, auto functions or humidistats stopping working and inconsistent performance are three of the most common dehumidifier problems, according to our survey of 1,000 owners.
Knowing which brands may develop the most faults can be useful when choosing a new one. That's why we asked Which? Connect panel members to tell us how pleased they are with their dehumidifier, whether they'd experienced any problems with it and whether they'd recommend their dehumidifier brand.
We've got data on some of the biggest brands including Meaco, Ebac and DeLonghi - so you can discover which ones won't let you down.
The table below summarises this year's results. Brands are ranked by their customer score, which reveals how satisfied owners are with their dehumidifier and how likely they are to recommend it, plus how each brand's dehumidifier scores on average in our independent lab testes.

Our lab tests cover some of the most important tasks a dehumidifier performs (including their water extraction, energy efficiency, humidistat function) as well as how easy they are to use and the noise they produce. But there are some things our extensive testing can't reveal - the most common dehumidifier faults is one of them.
Our Which? Connect panel members have reported the following as three of the most common dehumidifier faults:
Dehumidifiers are appliances that you need to leave running for a while, so noise can be a real problem. This is why we include a quietness rating in our dehumidifier testing.
Our expert lab testers subjectively rate how noisy each dehumidifier is. This can range from a gentle, barely noticeable hum to a great gurgling that makes the unit sound like it’s about to take off. Some dehumidifiers have variable speeds, so we also check how much noise each one makes at its highest and lowest settings.
We have a wealth of information on popular dehumidifier brands.
Every two years, we ask the Which? Connect panel members to tell us about their experiences with a range household appliances – from how likely they'd be to recommend a brand to a friend, to how long a product lasted before it developed a problem.
This year, more than 12,000 survey participants told us about more than 38,000 products, including 1,000 dehumidifiers.
Our survey results, combined with our independent testing data, mean we can give you an unrivalled insight into the dehumidifier brands you should opt for.
