The best dehumidifiers in 2026 for drying laundry, to prevent mould and reduce condensation

To fairly compare models, we put every dehumidifier through a series of structured, real-world tests. We begin with set up, assessing whether it can be unpacked and running within minutes or if it takes time to figure out.

We also judge ease of use, looking for clearly labelled and responsive controls. We check how easy it is to empty and reinsert the water tank and whether any companion app connects reliably and adds genuine control rather than gimmicks. Design details matter too, so we look at cable length, portability, self-draining features and safety cut-offs. Build quality, durability, extra features and overall value for money are all important.

Next, we assess its effectiveness. First, we measure how well a unit reduces humidity after a hot shower, recording how long it takes to bring the room back to a comfortable 50 per cent. Then, we test laundry mode by hanging a standard load of washing and noting how quickly it dries compared to normal conditions.

Finally, we measure noise levels with a decibel app and track energy consumption over the course of an hour using a plug meter.
