Water tank capacity: This is how much water the unit can hold, ranging from around 250ml to six litres. The smaller the dehumidifier, the more regularly you’ll have to empty the tank, though some larger models have a continuous drainage option through a hose. If you have a serious damp or condensation problem, it’s worth buying a model with a bigger tank so that it keeps working all night. How to choose the best dehumidifier for your home

Dehumidifiers can use a lot of energy, especially if used inefficiently. The electricity required to power a dehumidifier can be generated from a mixture of burning fossil fuels, renewables, gas and nuclear. But as this is mixed up in the grid, you can’t guarantee it’s coming from a renewable energy source. If you don’t want to think too hard about your usage, a device with an auto setting will be more efficient as it will only come on when the humidity levels go above your RH setting, saving you from wasting energy.
