Dehumidifiers
Dehumidifiers remove excess moisture from the air, helping with condensation on windows, damp patches and musty smells in bedrooms, bathrooms and living spaces. Compare dehumidifier type and room size guidance to find a unit suited to the space you want to treat.

How to choose a dehumidifier
Compressor vs desiccant vs Peltier
Compressor dehumidifiers work well in warmer rooms and are generally more energy-efficient for larger spaces, desiccant models perform more consistently in cooler conditions such as garages, and Peltier (thermoelectric) dehumidifiers are typically smaller and quieter but suit lighter-use, smaller rooms.
Room size and extraction rate
Check the manufacturer's guidance on room size or litres extracted per day, and match this to the space and the level of dampness you're dealing with, rather than choosing on price alone.
Tank capacity and continuous drainage
A larger water tank needs emptying less often, while some dehumidifiers support continuous drainage via a hose, which suits areas with persistent damp where you don't want to empty a tank daily.
Noise level
If the dehumidifier will run in a bedroom or living space, check its noise level, as compressor models can be louder than desiccant or Peltier units at similar extraction rates.
Humidistat and automatic control
A built-in humidistat lets the dehumidifier maintain a target humidity level and switch off automatically once reached, helping manage running time without constant manual adjustment.
FAQs
What is the difference between compressor and desiccant dehumidifiers?
Compressor dehumidifiers tend to be more efficient in warmer rooms, while desiccant dehumidifiers keep working effectively at lower temperatures, making them a common choice for garages, sheds or unheated spaces.
Where should I put a dehumidifier?
Place it in the room with the most moisture, condensation or musty smell, with some clearance around the unit for air to circulate, and away from walls or furniture that could block airflow.
How do I know if I need a dehumidifier?
Signs such as condensation on windows, damp patches on walls, a musty smell or visible mould can indicate excess moisture that a dehumidifier may help manage, alongside addressing any underlying ventilation issues.
