12L Low Energy Dehumidifier Review UK 2026
Quick verdict
Score: 7.7/10
Best for: Tackling damp, condensation and drying laundry around the home
Not for: Cold, unheated spaces below about 15°C, where a desiccant model copes better
Bottom line: A practical dehumidifier (12 litres/day) for keeping humidity down and preventing mould and condensation.
If someone wants a low-energy option for damp control in smaller spaces, this Other is a solid choice. The Other is designed for flats and apartments where damp can build up in corners, and it also claims air cleaning year round. It is positioned as a 2-in-1 unit with humidity control plus a HEPA filter included.

Pros
- Removes up to 12 litres/day
- Reduces damp, condensation and musty smells
Cons
- The water tank needs regular emptying unless you plumb in the drainage hose
- Running it adds to electricity use, so a humidistat or timer helps keep costs down
- Compressor models are less effective in cold rooms below about 15°C
Extraction Rate and Performance
With a stated capacity of 12 litres per day, this 2-in-1 unit is positioned to remove dampness at a moderate rate for flats, apartments and small homes. In daily use, extraction performance depends on how much moisture is present and on how consistently the unit runs. When humidity is higher, extraction can align more closely with the 12 L/day claim, while steadier indoor conditions can reduce the visible water output.
Room Size and Coverage
Coverage depends on the moisture load in the specific space, so room size should be considered alongside the extraction rate. The 12 litres/day figure points to suitability for flats, apartments and small homes, but the real-world result depends on how damp the room is. It helps to start in the main damp area, then monitor how quickly humidity readings stabilise. If the space is very large, or moisture comes from cooking, washing or poor ventilation, coverage may feel limited even if the unit runs continuously. For best results, keep doors mostly closed and improve airflow.
Tank Capacity and Drainage
Tank capacity and drainage directly affect how often the dehumidifier needs attention. A larger tank typically means fewer emptying cycles, while a smaller tank requires more frequent checks. The 12L low energy model is described as producing 12 litres per day, which indicates how quickly water can build up under typical damp conditions. Continuous drainage is mentioned as an option.
Noise Level
Noise level matters because it affects comfort, particularly in bedrooms, small flats and offices. For this Other, quiet operation is presented as a key feature, suggesting it is designed to run with less disruption. The unit is also described as a 2 in 1 dehumidifier and air purifier, so sound may come from both airflow and ongoing humidity control. In use, noise depends on placement and vibration, and on how long the unit needs to run to reach its humidity targets. Testing near sleeping areas and adjusting the setup can help reduce any rattling.
Energy Use and Running Costs
Even though this unit is marketed as a "low energy" 12L dehumidifier, the exact electricity use is not stated in the product title, so buyers should not assume a specific wattage or daily running cost. It is described as a 12L/day model, but that moisture-removal rate does not by itself indicate how much power will be used in a given room. Running costs vary with how damp the space is, how often moisture removal is triggered, and how long the unit runs overall. Anyone setting a UK electricity budget should treat running costs as variable because the electric power specifications needed to calculate them are not provided here.
Modes and Controls
Modes and controls determine how this Other handles dampness, and how much control the user has over day-to-day operation. Operation is based around selecting an operating state first, then running the dehumidifier until dampness improves. After that, it can be left on to help prevent new moisture building up. Controls are therefore set up for steady use rather than rapid, automated switching.
Compressor or Desiccant
A Other can use either a compressor system or a desiccant (water-absorbing) system, and the choice affects performance across different rooms and conditions. A compressor unit condenses water and removes it as liquid, which often suits warmer spaces where airflow can stay steady. A desiccant unit traps moisture inside a dry material, so it may keep working when temperatures are lower, although it usually needs time to recharge. Compressor models can be quieter during steady use, whereas desiccant models can be more flexible across seasons, depending on the room and humidity.
Who Is This Dehumidifier For?
This Other is designed for people who want moisture control in smaller spaces, such as flats, apartments, or small homes, where a daily removal capacity of 12 litres can help with everyday damp issues. It is offered as a 2 in 1 unit with an air purifier and a HEPA filter, so it is also positioned for cleaner air by capturing airborne particles as well as managing humidity. It is intended to support year-round comfort through humidity control and filtration.
Where to Buy in the UK
When choosing a Other with air purification, many buyers in the UK look to major electrical retailers and online marketplaces to compare models and confirm what is included. Listings can vary, so shoppers should compare products labelled "12L" and verify that the air purification feature includes a HEPA filter where stated, since bundles differ between brands and ranges. It is also important to check delivery options, collection details, and returns terms, as these directly affect how straightforward the purchase and post-purchase experience is. If controls are difficult to reach or the water tank access is awkward, daily use can become less convenient.
Frequently Asked Questions
Is the Other worth it?
If you have damp, condensation on windows, or laundry that will not dry, the Other earns its place by pulling moisture out of the air at up to 12 litres/day. It tackles the cause of mould and musty smells rather than masking them - check the current Amazon UK price, as it changes often.
Is the Other powerful enough for my home?
The Other is rated to remove up to 12 litres/day. The headline figure is measured in warm, very humid lab conditions, so real-world extraction is usually lower - size up if your problem is severe.
What does the Other cost to run?
Running cost depends on its wattage, how long it runs and your electricity tariff, so it is best checked against the stated power rating rather than a fixed figure. Using it on a timer or with a humidistat keeps running costs down.
Is the Other a compressor or desiccant dehumidifier?
Compressor models are most efficient in heated rooms; desiccant models cope better in cold spaces like garages. Check which type this is before buying for an unheated area.
How often do you empty the Other?
How often you empty the tank depends on the tank size and how damp the air is. For continuous running, look for a model with a drainage hose option.
Will the Other stop damp and mould?
By holding the room's humidity down, the Other removes the moisture that mould and dust mites need, which helps prevent condensation on windows and musty smells. Existing mould should still be cleaned off; the dehumidifier stops it coming back.
