Mould returning on ceilings, clothes not drying, multiple rooms affected. Mid-range 12L units with smart features are ideal.

→ See picks 3 through 7
3

Severe persistent damp

Walls visibly wet, heavy condensation daily, large or cold spaces. Go straight to a high-capacity compressor unit.

Free Advice

4 Ways to Prevent Damp Coming Back

Combine these habits with a dehumidifier for the best long-term results.

Ventilate when cooking

A single meal releases over a litre of water vapour. Open a window or run the extractor fan every time you cook.

Open doors after showers

Leave the bathroom door open for 30 minutes after bathing. Steam settles on walls and ceilings if it has nowhere to escape.

Never dry clothes indoors

One load of laundry releases up to 2 litres of moisture into the air. Use the Laundry Mode on your dehumidifier instead.

Keep a consistent temperature

Cold surfaces attract condensation. Even a steady 17°C prevents the cold spots where mould takes hold — especially in unused rooms.

Common Questions

Dehumidifier FAQs

The questions we get asked most — answered straight.

Match capacity to your home size: 1–2 bedroom flats need around 10–12L/day, 2–3 bedroom homes need 12–16L/day, and larger homes or those with persistent damp need 20–25L/day. The number on the box refers to litres extracted per 24 hours — not the tank size. If you dry clothes indoors regularly or have visible condensation every morning, go one step up from the guideline. See our comparison table above for a product matched to each size.
Most modern compressor dehumidifiers cost between 4p and 8p per hour to run. Running one overnight for 8 hours costs roughly 32p–64p. That is significantly cheaper than a tumble dryer (typically 30–50p per load), which is why using a dehumidifier to dry clothes indoors saves money over time. The Inventor Fresh 12L is the cheapest to run on our list at around 4p/hour, thanks to its R290 eco refrigerant.
Yes — but only if it runs overnight, when condensation actually forms. The problem occurs when warm, moist air hits cold glass during the night. A dehumidifier reduces the moisture in the air before it reaches the glass. Run it in the same room as the worst-affected windows and you should notice a significant difference within a few days. Our article on how to get rid of condensation on windows covers this in detail.
Compressor dehumidifiers are the most common type and work best in heated rooms above 10°C — which covers most British homes. They are more energy efficient and better value. Desiccant dehumidifiers use an absorbent material instead of cooling coils, which means they keep working in cold, unheated spaces like garages or conservatories. All ten products on this list are compressor models, suited for everyday home use.
Tank emptying depends on how humid your home is and the tank size — most people empty a 2L tank once or twice a day in winter. All the machines on this list have an automatic shut-off when the tank is full, so nothing overflows. For filters, a rinse under the tap every 4–6 weeks is usually enough. If you notice the machine collecting less water than usual, a dirty filter is often the cause.
Yes — but choose the right model. Not all dehumidifiers are quiet enough for overnight bedroom use. Look for one with a dedicated Sleep Mode that reduces noise and dims the display. The MONHOUSE 12L and MeacoDry Arete One are both specifically designed for this, running at 33–34dB overnight — quieter than a whispered conversation. A 24-hour timer means you can set it before bed without having to get up to switch it off. Read our guide on stopping bedroom mould for more detail.
