How to choose
- Litres per day: 10–12 L for a bedroom or flat, 20 L for a house. Box figures are measured in warm, humid lab conditions, so real winter extraction is lower.
- Humidity sensor: lets it stop at 50–55% and saves electricity.
- Laundry mode: runs at full power to dry a load of washing in a closed room.
- Continuous drainage: a hose to a sink or drain means no emptying the tank.
- Room temperature: below about 15 °C, choose a desiccant model.
