## Quick answer

The best dehumidifier for home use is the Pro Breeze 12L at £134.99: it is a Which? Best Buy, runs below 38dB, costs about 5p an hour, and 5,694 owners rate it 4.6. For the most extraction per pound, the KNKA 16L costs £99.99, and for a whole house or drying laundry, the Pro Breeze 20L has a 5.5L tank for £179.99.

The best dehumidifier for home use depends on one number above all: how many litres it pulls from the air each day. A 12L unit suits a damp bedroom or a flat, while 20L handles a bigger house, a cold basement or a rack of wet washing.

After that, two things decide how pleasant it is to live with. The first is the tank, because a small tank means emptying it several times a day. The second is noise, because most people run a dehumidifier in a bedroom or living room.

Below, we ranked 10 popular dehumidifiers on extraction, tank size, running cost, noise and how many buyers back each one. Prices were checked on Amazon on 16 October 2026, just as damp season starts in the UK.

## The ranking

### 1. Pro Breeze 12L

- Price: £134.99 | Amazon rating: 4.6 from 5,694 ratings | ranked10 score: 9.2/10
- Full review: https://www.ranked10.co.uk/home/best-dehumidifier-for-home/pro-breeze-12l
- Buy on Amazon: https://www.amazon.co.uk/dp/B073XNK45P?tag=ranked10-21

The best dehumidifier for most homes: a Which? Best Buy, under 38dB and about 5p an hour.

The Pro Breeze 12L is the best dehumidifier for home use in most flats and smaller houses. It is a Which? Best Buy for 2025, runs below 38dB, and 5,694 owners rate it 4.6, the biggest record in this list.

It draws 200W, which works out at about 5p an hour at 25p per kWh. In addition, the humidity sensor lets you set a target between 30% and 80%, and the unit switches off when it gets there.

The one compromise is the 1.8L tank, which can fill in about 3.5 hours at full speed. For constant running, connect the drain hose that comes in the box.

Pros: Which? Best Buy 2025; Under 38dB, quiet enough for a bedroom; About 5p an hour at 200W; 5,694 ratings at 4.6, the most here
Cons: Small 1.8L tank; Price up from £114.74 to £134.99; 12L suits a room or flat, not a large house

### 2. KNKA 16L

- Price: £99.99 | Amazon rating: 4.4 from 2,025 ratings | ranked10 score: 8.9/10
- Full review: https://www.ranked10.co.uk/home/best-dehumidifier-for-home/knka-16l
- Buy on Amazon: https://www.amazon.co.uk/dp/B0FKLX55JG?tag=ranked10-21

The best value here: 16L a day, a 3L tank and about 6p an hour, for £99.99.

The KNKA 16L is the best dehumidifier for home use on a budget, with the most extraction for the money among the well-rated units here. At £99.99 it pulls up to 16 litres a day, has a 3L tank, and 2,025 buyers rate it 4.4.

It draws up to 260W, and KNKA puts the running cost at 6p an hour. It also has auto defrost for cold rooms, a sleep mode that turns the lights off, a child lock and a full-tank alarm.

Bear in mind that KNKA measures the 16L at 35°C and 90% humidity, which is far warmer and wetter than a British home in winter. Even so, it should outperform the 12L units at a lower price.

Pros: 16L a day for £99.99; 3L tank with a level window; Auto defrost for cold rooms; Price down from £139.99
Cons: 16L rating measured at 35°C and 90% humidity; Spec table lists 12L a day, not 16L; Noise level not stated

### 3. Pro Breeze 20L

- Price: £179.99 | Amazon rating: 4.5 from 2,529 ratings | ranked10 score: 8.7/10

- Buy on Amazon: https://www.amazon.co.uk/dp/B0C62J7S74?tag=ranked10-21

The best for larger homes and laundry: 20L a day, a 5.5L tank and a Which? Best Buy.

For a larger house, a cold room or drying laundry, the Pro Breeze 20L is the one to buy. It is a Which? Best Buy for 2025, and Which? notes that it works reasonably well in colder rooms, where many compressor units struggle.

Its 5.5L tank means far fewer trips to the sink, and it has 5 modes, including laundry, plus a carbon filter for musty smells and a louvre that swings through 120 degrees.

With 2,529 ratings at 4.5 it is well proven. However, at £179.99 it is the most expensive unit here, and it stands 60.8cm tall.

Pros: Which? Best Buy 2025; Works well in colder rooms, says Which?; 5.5L tank; Carbon filter for musty smells
Cons: £179.99, the most expensive here; 60.8cm tall; Price up from £161.49

### 4. Devola 12L

- Buy on Amazon: https://www.amazon.co.uk/dp/B09FXYHCC9?tag=ranked10-21

The quietest here at 36dB, about 5p an hour, with a Which? Great Value award.

The Devola 12L is the pick for a bedroom, because it runs at just 36dB at full speed, the joint quietest in this list. It also holds a Which? Great Value award and Good Housekeeping Institute approval.

Devola puts the running cost at 5p an hour at 24p per kWh, and it has a laundry mode, a washable dust filter and a 2L tank with a drain hose.

At £139.90 it costs £4.91 more than the Pro Breeze 12L, with a slightly bigger tank and a quieter rating, but with 929 ratings it has a smaller track record.

Pros: 36dB, joint quietest here; About 5p an hour; Which? Great Value award; Washable dust filter
Cons: 10.5kg, heavy for a 12L unit; 929 ratings, fewer than Pro Breeze; 1-year warranty as standard

### 5. PureMate 20L

- Price: £144.49 | Amazon rating: 4.6 from 264 ratings | ranked10 score: 8.2/10
- Full review: https://www.ranked10.co.uk/home/best-dehumidifier-for-home/puremate-20l
- Buy on Amazon: https://www.amazon.co.uk/dp/B0C9YR76G9?tag=ranked10-21

20L a day with the biggest tank here at 6.5L, praised by Which?, for £144.49.

The PureMate 20L pairs 20 litres a day with a 6.5L tank, the biggest in this list, so it can run for hours between empties. Its listing quotes Which? calling it the highest-scoring dehumidifier it has tested.

It has a humidity sensor with a 3-colour light, a laundry mode, a 24-hour timer, two fan speeds and an optional ioniser.

Its price has dropped from £169.99 to £144.49, which makes it £35.50 cheaper than the Pro Breeze 20L. However, only 264 buyers have rated it, and it quotes up to 45dB.

Pros: 6.5L tank, the biggest here; Strong Which? test score; Price down from £169.99; Laundry mode and ioniser
Cons: Only 264 ratings; Up to 45dB; 57cm tall

### 6. Hangsun 20L

- Price: £139.99 | Amazon rating: 4.6 from 447 ratings | ranked10 score: 8.0/10

- Buy on Amazon: https://www.amazon.co.uk/dp/B0C9TCFNL9?tag=ranked10-21

20L a day with a 4.5L tank and colour humidity lights, rated 4.6, for £139.99.

The Hangsun 20L is a solid 20L unit for £139.99, £40 less than the Pro Breeze 20L. It has a 4.5L tank, a colour-coded humidity light and 3 modes: auto, continuous for laundry, and sleep.

In addition, it has auto defrost, a 24-hour timer, a child lock and 360° wheels, and 447 buyers rate it 4.6.

It draws 280W, about 7p an hour at 25p per kWh, and runs below 41dB in sleep mode. At 12.5kg, though, it is one of the heaviest units here.

Pros: 20L a day for £139.99; 4.5L tank; Colour humidity lights; 4.6 stars from 447 ratings
Cons: 12.5kg; Below 41dB only in sleep mode; About 7p an hour

### 7. Honeywell 12L

- Price: £159.50 | Amazon rating: 4.4 from 784 ratings | ranked10 score: 7.6/10
- Full review: https://www.ranked10.co.uk/home/best-dehumidifier-for-home/honeywell-12l
- Buy on Amazon: https://www.amazon.co.uk/dp/B0CHS9N5BX?tag=ranked10-21

A low-running-cost 12L with a 2.5L tank and Good Housekeeping approval, but louder and pricier.

The Honeywell 12L focuses on running cost: Honeywell puts it at 5p an hour at 25p per kWh, and it uses R290, an eco-friendly refrigerant. It also has Good Housekeeping Institute approval for 2025.

Its 2.5L tank is bigger than the Pro Breeze 12L's, and you can set humidity from 30% to 90% in 5% steps. There are 4 modes, including laundry, plus auto defrost and a 24-hour timer.

However, it is louder than its rivals at 40dB, rising to 42.5dB on laundry mode, and at £159.50 it is the most expensive 12L unit here.

Pros: About 5p an hour; 2.5L tank; Humidity control in 5% steps; Eco-friendly R290 refrigerant
Cons: 40dB to 42.5dB, loud for a 12L; £159.50, the priciest 12L here; 10.3kg

### 8. HumiZap 12L

- Price: £99.99 | Amazon rating: 4.4 from 677 ratings | ranked10 score: 7.3/10
- Full review: https://www.ranked10.co.uk/home/best-dehumidifier-for-home/humizap-12l
- Buy on Amazon: https://www.amazon.co.uk/dp/B0C8JT1SZ8?tag=ranked10-21

A quiet 12L at under 36dB for £99.99, but with the smallest tank here at 1.6L.

The HumiZap 12L quotes under 36dB, the joint quietest figure here, and costs £99.99. It extracts 12 litres a day, has 3 modes including laundry, and 677 buyers rate it 4.4.

It also comes with a 2-year limited warranty, a 24-hour timer, a night mode and hidden side handles.

However, its 1.6L tank is the smallest in this list, and at the same £99.99 the KNKA extracts 16L with a 3L tank. Its price has also risen from £85.48.

Pros: Under 36dB; 2-year limited warranty; £99.99
Cons: 1.6L tank, the smallest here; KNKA extracts more for the same price; Price up from £85.48

### 9. AEOCKY 25L

- Price: £119.97 | Amazon rating: 4.5 from 287 ratings | ranked10 score: 7.0/10
- Full review: https://www.ranked10.co.uk/home/best-dehumidifier-for-home/aeocky-25l
- Buy on Amazon: https://www.amazon.co.uk/dp/B0FSLK3DD9?tag=ranked10-21

The most extraction here at 25L a day in a compact body, but its 1.9L tank fills in under 2 hours.

The AEOCKY 25L has the highest extraction in this list, 25 litres a day, in a compact 43cm body. It uses a brushless DC inverter motor and is rated for spaces of up to 50 square metres, for £119.97.

It has 4 modes, continuous, sleep, auto and constant humidity, and the wheels are optional, so it can sit on a shelf or in a wardrobe.

The catch is the 1.9L tank. At the full 25 litres a day it fills in under 2 hours, so in practice you need the continuous drain. It also draws 360W, about 9p an hour.

Pros: 25L a day, the most here; Compact 43cm body; Inverter motor; £119.97
Cons: 1.9L tank fills in under 2 hours at full speed; 360W, about 9p an hour; 287 ratings

### 10. Nyxi 20L

- Buy on Amazon: https://www.amazon.co.uk/dp/B0CX5C84BX?tag=ranked10-21

20L a day with a 6.5L tank for £139.97, but the loudest here at up to 48dB.

The Nyxi 20L has a 6.5L tank, joint biggest here, and extracts up to 20 litres a day for £139.97. It has a touch panel, a 3-colour humidity lamp, a 24-hour timer, auto defrost and a washable filter.

However, it quotes up to 48dB, the loudest in this list, and draws 320W, about 8p an hour.

With 432 ratings at 4.2, it also has the lowest score here. Meanwhile, the PureMate 20L has the same tank for £4.52 more and quotes 45dB.

Pros: 6.5L tank; 20L a day for £139.97; Auto defrost and washable filter
Cons: Up to 48dB, the loudest here; 4.2 stars, the lowest here; About 8p an hour at 320W

## What size dehumidifier do you need for your home?

For a single damp room, a bedroom or a flat of up to two bedrooms, 12 litres a day is plenty. For a three or four bedroom house, a cold room, a basement or regular laundry drying, choose 16L to 20L.

Ignore the floor area field on Amazon when you choose. On these listings it ranges from 1 square foot for the Devola to 4,500 square feet for the Nyxi, which says more about the listings than the machines.

## How often will you have to empty the tank?

Divide the tank by the extraction per hour to see the worst case. At full speed, the AEOCKY's 1.9L tank fills in under 2 hours, the Pro Breeze 12L's 1.8L tank in about 3.5 hours, and the 6.5L tanks on the PureMate and Nyxi in nearly 8 hours.

In a real British home the machine extracts less than its rating, so the tank lasts longer. However, if you cannot empty it often, choose a big tank or use the drain hose, which every unit here includes.

## How much does a dehumidifier cost to run?

Multiply the wattage by your electricity price. At 25p per kWh, a 200W to 210W unit such as the Pro Breeze 12L, the Devola or the Honeywell costs about 5p an hour. Meanwhile, the 360W AEOCKY costs about 9p an hour.

Most units also switch off once the room reaches your target humidity, so they rarely run flat out all day. Set the target to around 50% and let the humidity sensor do the rest.

## Why do extraction figures look so high?

Brands measure them in hot, wet test conditions. KNKA rates its 16L at 35°C and 90% humidity, and Nyxi rates its 20L at 30°C and 80%. A British home in winter is far cooler, so expect less water each day than the box says.

Cold rooms are where compressor units struggle most. That is why Which?'s comment that the Pro Breeze 20L works reasonably well in colder rooms is worth noting if your damp problem is in a cold spot.

## Which dehumidifier is quietest for a bedroom?

The Devola and the HumiZap quote 36dB, and the Pro Breeze 12L quotes under 38dB. In contrast, the Honeywell runs at 40dB to 42.5dB, and the Nyxi quotes up to 48dB.

For a bedroom, also look for a sleep mode that dims the lights. The Pro Breeze, KNKA, Hangsun and HumiZap all have one.

## Can a dehumidifier dry your laundry?

Yes, and it is much cheaper than a tumble dryer. Most units here have a laundry mode that runs the fan harder. For a full rack of washing, a 20L unit with a big tank, such as the Pro Breeze 20L, works best.

## Verdict

So, which is the best dehumidifier for home use? For most people, the Pro Breeze 12L at £134.99. It is quiet, cheap to run and backed by 5,694 ratings and a Which? Best Buy.

If you want the most extraction for the money, buy the KNKA 16L at £99.99. And for a bigger house or drying laundry, the Pro Breeze 20L's 5.5L tank means far fewer trips to the sink.

## FAQ

**What is the best dehumidifier for home use?**

The Pro Breeze 12L at £134.99 for most homes. It is a Which? Best Buy, runs below 38dB, costs about 5p an hour, and 5,694 owners rate it 4.6.

**What size dehumidifier do I need?**

12 litres a day for a single room, a bedroom or a small flat. 16L to 20L for a larger house, a cold basement or regular laundry drying.

**How much does it cost to run a dehumidifier in the UK?**

At 25p per kWh, about 5p an hour for a 200W to 210W unit and about 9p an hour for a 360W unit. Most switch off once they reach your target humidity, so the real cost is lower.

**Where is the best place to put a dehumidifier?**

In the dampest room, away from walls and furniture so air can flow, with doors and windows shut. Move it between rooms if you have damp in more than one.

**What humidity should I set my dehumidifier to?**

Around 50%. Between 40% and 60% is comfortable for most homes, and keeping it below about 60% makes it much harder for mould to grow.

**Is a dehumidifier cheaper than a tumble dryer for laundry?**

Yes. A 200W to 300W dehumidifier on laundry mode costs a few pence an hour, while a tumble dryer typically draws well over 2,000W.

**Do dehumidifiers work in cold rooms?**

Compressor dehumidifiers lose efficiency below about 15°C. Look for auto defrost, which most units here have, and note that Which? says the Pro Breeze 20L works reasonably well in colder rooms.
