Auto functions or humidistats stopping working, inconsistent performance and complete failure are three of the most common dehumidifier problems, according to our most recent survey data. Knowing which dehumidifier brands are the most prone to faults could save you money.

To discover the dehumidifier brands you can depend on, we asked 6,997 Which? Connect panel members and 3,003 members of the general public to tell us how happy they are with their dehumidifier, whether they had experienced any problems with it and whether they would recommend the brand.

We've crunched the numbers for the biggest dehumidifier manufacturers, including DeLonghi, Ebac and Meaco, and have calculated a customer score for each, so you know which brands are recommended by owners.

Table notes: The customer score, proportion faulty and proportion repaired or replaced are based on a survey of 1,494 people who own a dehumidifier, conducted in May 2022. The proportion faulty and proportion repaired or replaced is based on appliances bought in the past seven years.

Best vs worst dehumidifier brands

As you can see in our table, there's a big difference between the best and worst dehumidifier brands in both the satisfaction score reported by customers and the proportion of appliances that develop faults.

	Best	Worst
Customer score	84%	70%

Proportion repaired or replaced due to a fault	0%	14%

The three most common dehumidifier faults

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 survey respondents have reported the following as three of the most common dehumidifier faults:

4% Stopped working/complete failure
2% Stopped collecting water
2% Became too noisy

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 noinse 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.

If your dehumidifier is less than six months old and you experience problems such as a function failure or a complete failure, see our faulty goods advice guides to see how you can take action. In our survey, 18% of people had the dehumidifier replaced by the manufacturer or retailer, while 14% had the dehumidifier repaired under the manufacturer warranty.

Unfortunately, 24% had to stop using their dehumidifier once it had a fault and disposed of it. Head to our dehumidifier guide to find out how to dispose of one.

How we calculate the best and worst dehumidifier brands

We have a wealth of information on popular dehumidifier brands.

This year, we asked more than 6,997 Which? members and 3,003 members of the public to tell us about their experiences with a range of household appliances – from how likely they would be to recommend a brand to a friend to how long a product lasted before it developed a problem.

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.
