De'Longhi DEX212F Dehumidifier (White/Dark Grey Heather)

How much electricity does the DEX212F use per day?

The unit consumes 300 watts of power when operating. Running continuously for 24 hours would use 7.2 kWh of electricity. However, the automatic humidity control means it cycles on and off as needed, typically reducing actual consumption to 3-5 kWh daily depending on room humidity levels and settings used.

Can I use this dehumidifier in my bedroom overnight?

Yes, the 40 decibel noise level makes it suitable for bedroom use. This is equivalent to a quiet library and won't disturb most people's sleep. The unit has front-facing indicator lights that aren't overly bright and the auto-restart function means it will resume operation if power is briefly interrupted during the night.

How often do I need to empty the water tank?

The 2.1-litre tank typically needs emptying every 4-8 hours during initial use in very humid conditions. Once room humidity stabilises, emptying may only be needed once daily. The transparent tank makes water level monitoring easy and the unit automatically stops when full. For continuous operation, connect the included drainage pipe to a sink or drain.

What room size is this dehumidifier suitable for?

The DEX212F effectively covers rooms up to 55 cubic metres, equivalent to a 20-25 square metre room with standard 2.4m ceilings. For larger spaces, you may need multiple units or a higher capacity model. The integrated handle makes moving between rooms straightforward if you want to target specific areas.

Does the laundry function really speed up clothes drying?

Yes, the laundry function optimises both fan speed and dehumidifying capacity specifically for drying clothes. Users report clothes drying 50% faster compared to air drying alone. The function works best in a closed room with wet laundry, creating optimal conditions for moisture extraction from fabrics whilst circulating dry air.

How do I clean and maintain the filters?

The anti-dust filter should be cleaned monthly by vacuuming or rinsing with lukewarm water. The anti-allergen filter is removable and washable - rinse monthly and allow to dry completely before reinstalling. Both filters are easily accessible from the front of the unit. Clean filters maintain optimal air flow and extraction efficiency.

Will this dehumidifier work in cold conditions like a garage?

The electronic anti-freeze protection allows operation down to 2°C, making it suitable for unheated garages, conservatories and outbuildings. Below 2°C, the unit may not operate effectively as the coils could freeze. For consistently cold spaces below 2°C, consider a desiccant dehumidifier instead.

What's included in the box and what warranty is provided?

The box contains the DEX212F dehumidifier, drainage pipe for continuous operation and user manual with full operating instructions. De'Longhi provides a standard manufacturer's warranty and Amazon offers a 30-day return policy. The unit weighs 9kg and measures 20cm high, 13.1cm wide and 8.7cm deep when positioned for use.
