# Best dehumidifiers for garages, sheds and cellars Source: https://dampanddry.co.uk/best/best-dehumidifier-for-garage-and-cellar Publisher: Damp and Dry. Picks are based on what the Amazon listings state, not on hands-on testing. Method: https://dampanddry.co.uk/how-we-pick Garages, sheds and cellars are hard places for a dehumidifier. They are often below 10 °C in winter, which slows most compressor machines, and nobody wants to walk out to empty a tank every day. A good pick for these spaces keeps extracting in the cold, can drain through a hose to a gully or sink, and restarts on its own after a power cut so it keeps working while you are away. This guide compares seven machines on those points. Six are desiccant units that the makers say work down to 1 °C or below 10 °C. One is a large De'Longhi with a lift pump and anti-freeze function for a cellar where water has to be pumped upwards. All facts come from each listing. ## Products ### 1.
