Telegraph: Dehumidifier buying guide and best models

The Telegraph’s Recommended guide explains how dehumidifiers can help UK households combat damp, condensation and slow-drying laundry, while keeping running costs manageable. Excess moisture in the air can encourage mould growth, damage furnishings and make rooms feel colder, and the guide positions dehumidifiers as a practical solution for everyday homes rather than specialist equipment.

The article outlines how dehumidifiers work by drawing moisture from the air and stresses the importance of choosing the right capacity for your space. Rather than focusing on physical size, buyers are advised to look at how many litres of water a model can extract in 24 hours, with smaller rooms typically suited to 10–12L units and larger or persistently damp homes needing 15–20L or more. Two main types are covered: compressor models, which are generally more energy-efficient in heated rooms, and desiccant models, which perform better in colder spaces but use more electricity.

Testing was carried out in real homes, assessing ease of setup, usability, tank design, portability, noise levels and energy consumption. Performance was measured by tracking how quickly humidity dropped after showers and how effectively laundry dried indoors. Many models now include laundry modes, built-in hygrometers, child locks and options for continuous drainage, while higher-end units offer smart app control and air filtration.

The guide highlights clear category winners, including a best buy, best value option, and specialist picks for laundry drying, bathrooms and smart features. Running costs are a key theme, with most compressor dehumidifiers typically costing between 4p and 8p per hour under the current energy price cap. Overall, the Telegraph presents dehumidifiers as an efficient alternative to tumble dryers and a worthwhile investment for maintaining a healthier, more comfortable home.
