What size and type of dehumidifier should I buy?
Patrick Gallagher, Which? researcher, says:
Choosing a type
'The type of dehumidifier you choose will depend on the conditions of the space you want to use it in.
'Refrigerant dehumidifiers are typically more energy efficient and work best in normal room temperatures, but they'll struggle (or not work at all) in rooms below 10°C.
'If you need a dehumidifier for an unheated room, such as a cellar, garage or attic, then you'll want to buy a desiccant model. These are designed in a way that allows them to function more effectively in cold rooms.'
Choosing a size or capacity
'As for the size or capacity of a dehumidifier, this describes how many litres of water it's able to extract from the air each day, and ranges from seven to 40 litres. Which capacity you need depends on the size of the space you want to use it in, how many people are living in the home generating moisture through activities such as cooking, washing and doing laundry, and the extent of the damp problem.
'A seven to 12-litre capacity model will suit a single person living in a small flat, looking to tackle a mild damp problem. Dehumidifiers with a capacity of 14 to 16 litres are suitable if there are more of you creating moisture, or your damp problem is more severe.
'If you have a lot of moisture you need to get rid of fast, then you'll likely want a model with a large capacity of 18-plus litres.'

How to recycle old appliances
If you're looking to replace an ageing dehumidifier by shopping the winter sales, make sure you dispose of your old one in a sustainable way.
One option is kerbside collection for small electrical items. In many cases, your local council will collect smaller items such as toasters and kettles. Alternatively, you can drop items at a local recycling centre or hand them over to retailers that have their own recycling schemes.
For more details on how to get rid of your unused gadgets, read our guide on how to recycle electrical items.
