Tested dehumidifiers

Which? finds a dehumidifier that froze over during its chilly conditions test.

A dehumidifier has failed our water extraction at 10˚C test after its evaporator grid froze over. The dehumidifier in question is among the more expensive models we’ve tested.

After freezing over, the dehumidifier was unable to pull any moisture from the air.

We alerted the manufacturer to this finding. As a result, it conducted its own tests and told us that it found no failures and disputes our test results.

However, the manufacturer has said that if any customer does experience a problem with this dehumidifier – whatever its age or warranty status – it will either replace it with a new version or give a full refund.

We tested two samples of the dehumidifier, to help ensure the first dehumidifier we looked at wasn’t a faulty model.

If you’d rather avoid the dehumidifier that froze over during our 10˚C water extraction test – which is particularly important if you want to buy a dehumidifier for a chillier space, such as a garage or caravan – make sure you check out our dehumidifier reviews.
