⭐ Performance: What Customers Actually Experience
✔ Strong moisture extraction for medium rooms
Customers consistently praise how quickly the Daewoo 12L pulls moisture from the air. Many reviewers mention that it collects a surprising amount of water within hours, especially in winter or in rooms with poor ventilation.
Robert Dyas customers highlight that it “efficiently manages moisture in living rooms, bedrooms, and home offices” and is particularly effective for tackling condensation and damp smells.
✔ Great for drying clothes
Several buyers mention using the Continuous/Drying mode, which runs the unit at full power. One eBay reviewer specifically praised the clothes‑drying feature and the choice of settings available. This makes it a cost‑effective alternative to tumble drying.
✔ Reliable for preventing mould
Because it extracts up to 12 litres per day, customers find it effective for preventing mould on walls, window frames, and cold corners — especially in older UK homes.
⭐ Noise Levels: Quiet Enough for Daily Use
While not silent, customers describe the Daewoo 12L as quiet for its size. On eBay, reviewers rated it 85% “quiet”, which is impressive for a compressor‑based unit.
Users say:
- It’s fine for living rooms
- Acceptable for bedrooms on Sleep Mode
- Noticeably quieter than older dehumidifiers
The Sleep Mode reduces fan speed and noise, making it suitable for night‑time operation.
⭐ Energy Efficiency: Good for a 12L Unit
Although exact wattage isn’t listed in the search results, customers frequently mention that it’s cheaper to run than expected and significantly more efficient than using a tumble dryer for laundry.
The timer function (1–24 hours) helps users control energy usage by running the unit only when needed.

Customers repeatedly highlight how simple the Daewoo 12L is to operate:
- Clear LED display
