Cheapest price in the past six months: £130*

• Type: Refrigerant
• 44.5 x 29.5 x 25cm (H x W x D), 11.5kg

According to Meaco, this dehumidifier is its quietest dehumidifier at just 36dB - for comparison, that's slightly less humming than a quiet library. 

It's a suitable size for flats or houses with up to three bedrooms, and Meaco claims it costs just 4p per hour to run. Features include a 24-hour timer, 2-litre water tank, child safety lock and auto-restart in the event of a power cut.

Ecoair DD3 Classic MK3

Average price in the past six months: £290
Cheapest price in the past six months: £239*

• Type: Desiccant
• 51.9 x 40.3 x 24cm (H x W x D), 7.36kg

This is a good choice if you want a dehumidifier that works well in both warm and cold spaces, which is something that some refrigerant models can struggle with.

You'll need to lift it if you want to move it around, as it lacks castors, but luckily, it's one of the lighter models we've tested. A laundry mode, 12-hour timer and five target humidity levels give you options for quick-hit or sustained moisture reduction.

Meaco Arete One 20L

Average price in the past six months: £266
Cheapest price in the past six months: £200*

• Type: Refrigerant
• 61.8 x 37.1 x 27.4cm (H x W x D), 15.1kg

Meaco says that this is two products in one - both a dehumidifier and an air purifier. It has a 4.8-litre tank with top handle and twin pouring spouts, to help you empty the water container with fewer spills. 

Other features include a night mode, laundry mode, child lock and a top-mounted LCD control panel. One HEPA filter is included for dual dehumidifying and air purification functionality.

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 and how many people are living in the home and generating moisture through activities such as cooking, washing and doing laundry, and the extent of the damp problem.

'A model with a capacity between 7 and 12 litres 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 at least 18 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.
