Best budget dehumidifiers under £100 to tackle damp and dry laundry
If you're looking for ways to tackle damp and speed up drying laundry, without spending a fortune, you've come to the right place. I've tested the UK's best dehumidifiers under £100 - these are the ones worth buying.
By Laura Cooke | Last updated Dec 30, 2025
The best dehumidifiers are effective, energy-efficient and quiet - we should know, we've tested tons of them. But effective dehumidifiers often come with a hefty price tag. There are plenty of low-priced dehumidifiers on the market, but how can you ensure you're getting the best budget dehumidifier for your money?

With the cost of living crisis continuing to bite, keeping energy bills down is a priority for many of us over the colder months. That's why we've tried and tested the budget dehumidifiers Mumsnet users recommend, to bring you our definitive list.
If you're looking to reduce your electricity bills, you may have already switched from a tumble dryer to a heated clothes airer to dry your laundry indoors. Having a dehumidifier running in the room will prevent moisture from the clothes from settling on the walls and making the room damp.

How we chose the best budget dehumidifiers
Taking our cues from the low-cost dehumidifiers Mumsnet users recommend most highly, we first assembled a shortlist of dehumidifiers under the £100 mark. Cross-referencing these choices with expert opinions and consumer reviews, we hand-tested the best cheap dehumidifiers on the market in real family homes.
Here's Mumsnet’s pick of the best budget dehumidifiers for 2026.
Best budget dehumidifier overall
Lightweight and portable
It has no compressor, so it makes very little noise
Great energy efficiency
Less effective in larger rooms
Key specs
Price on writing: £46 | Type: Thermo-electric peltier dehumidifier | Extraction amount: 500ml | Tank capacity: 1500ml | Dimensions: H30 x W21.8 x D6.3cm | Weight: 1.85kg | Power: 40W | Cost per hour: 1p | Noise level: 33dB | Max room size: 150sq/ft | Laundry mode: No | Warranty: 1 year
What Mumsnet users say
Tested by Poppy O'Neill: Read our in-depth Pro Breeze 1500ml Portable Dehumidifier review
The Pro Breeze Dehumidifier is compact, low-cost and energy-efficient - there’s no ugly, giant white box rattling away noisily in the corner here. In fact, with a noise level of just 34dB, I found it to be barely louder than a whisper, which makes it ideal for my home office.
With an extraction rate of up to 500ml daily and a water tank of 1500ml, this dehumidifier won’t eliminate a severe damp problem and is not as effective in larger rooms (you may need to bring in the big guns if you have a particularly serious damp problem over a large area). However, it will remove moisture from smaller spaces, effectively managing mould build-up and absorb condensation during the morning. I found it sped up the process of drying laundry, but only when tested in a small space. All for well under £100. That’s an absolute bargain, if you ask us, and that's why we've named this one the best budget dehumidifier for 2026.
Best moisture absorber

Cost-effective refills

Needs to be stored out of reach of children and pets (liquid can cause eye irritation)
Key specs
Price on writing: £9 | Type: Moisture Absorber | Extraction amount: 12L | Tank capacity: 2.5L | Dimensions: H19.7 x W15.2 x D14.7cm | Weight: 0.8kg | Power: None required | Cost per hour: Free | Noise level: 0dB | Max room size: 20m² | Laundry drying mode: No | Warranty: N/A
What Mumsnet users say
Reviewed by Mumsnet editor Poppy O'Neill: Read our in-depth Unibond Aero 360 Compact review
Silent, compact and non-electric, the Unibond Aero 360 Compact Moisture Absorber is a brilliant way to tackle damp in small or hard-to-reach spaces - as well as spots without a power socket. Firstly, it requires no extra energy consumption (much like using clothes pegs and a rotary washing line, going back to basics is an easy way to reduce your energy bills) - and doesn't make a sound. Secondly, a moisture absorber removes excess water from the air (just like a dehumidifier), and thirdly, you can buy cost-effective refill packs of two, each lasting three months.
Ideal for small spaces or rooms, I targeted specific areas of damp and mould in cupboards, bathrooms and laundry rooms and were impressed with how good it is against condensation. Just slot the tablet into the top, and that’s it. However, we recommend you make sure you’ve put it out of reach of children or pets, as the bright blue salt solution is an irritant.
So, how does it work? The tablet uses activated crystals and anti-odour agents to absorb moisture and neutralise foul odours simultaneously. The wave-shaped surface of the top helps to enhance circulation and air exposure, collecting as much moisture as possible as a solution in the container. A tablet already comes included, but you can easily buy standard refills (pack of two) from several places.

Timer function
Humidity level sensor display
A little on the noisy side
Makes a distracting sound every time a new option is selected
Less effective in larger rooms
Key specs
Price on writing: £60 | Type: Dehumidifier | Extraction amount: 800ml per day | Tank capacity: 2,300ml | Dimensions: 30.5 x 15.3 x 22.3 cm | Weight: 2.2kg | Max room size: 250 sq ft | Laundry mode: No | Cost per hour: 2p
Reviewed by Poppy O'Neill: Read our full CONOPU 2300ml Dehumidifier review
With three modes - strong, sleep and auto - and a timer function, the CONOPU 2300ml Dehumidifier gets the job done with minimal fuss. I found the controls easy to use, and the handy humidity sensor display shows how well the dehumidifier is performing.
The downside to the CONOPU is that it isn’t the quietest machine on our list, plus it makes a rather annoying noise when the settings are changed. However, costing just 2p per hour to run, this handy gadget makes a huge difference to my home without impacting too much on my energy bills.

Quietest budget dehumidifier

Whisper quiet

Key specs
Price on writing: £45 | Type: Compressor Dehumidifier | Extraction amount: 300ml | Tank capacity: 600ml | Dimensions: H22 x W14 x D14cm | Weight: 0.9kg | Power: N/A | Cost per hour: N/A | Noise level: 35dB | Max room size: 15m² | Laundry mode: No | Warranty: 2 year
Tested by Laura Cooke: Read our full Russell Hobbs RHDH1061G Dehumidifier review
Lightweight, small, and oh so quiet, this dehumidifier comes in sleek black or stylish grey, and blended seamlessly into my living space. As it has a compact design, it's suited to be used in rooms no bigger than 15m² and the water tank can only hold 600ml at a time, making it perfect for tackling damp in caravans, garages, and smaller rooms like home offices, box rooms and utility rooms.
The one-touch button meant I found the Russell Hobbs dehumidifier incredibly easy to operate. Some Mumsnetters have been so impressed with the machine’s performance, they bought several to dot around the home. Costing less than £50 each, this would be a valuable investment in the fight against damp.

Are cheap dehumidifiers worth it?
If you only have a small area affected by damp, such as a box room, home office, caravan or inside a wardrobe, then a small, cheap dehumidifier under £100 is a great buy. If your damp problem is more serious, then you will need to invest in something more powerful. It is also worth knowing that smaller dehumidifiers are less effective when used in larger rooms. Check out our comprehensive guide to the best dehumidifiers for some useful tips on choosing the best dehumidifier to meet your needs.

What does a dehumidifier do?
A dehumidifier removes excess moisture from the air to dry out the room, depositing it safely inside its water tank until you are ready to pour it away. Its job is to help you reach the optimum humidity level, and some even act as an air purifier, removing allergens and dust through their filter.
They can range in price from £30 to £450, and cheaper units tend to have a smaller capacity. They won’t always have extra features such as wheels, variable humidity levels or a laundry mode, but that may be enough for a small space or to treat a mild damp problem. The more expensive models tend to be more energy-efficient in larger rooms or households, but that doesn’t always mean they are the most effective.
Dehumidifiers do not kill mould, but they help make it inert and stop it from spreading (the spores love humid air!). You need a dehumidifier to treat the underlying cause and a good mould killer to eliminate it completely. Here’s our guide to the best mould removers so you can clean it off any surface and stop it from regrowing.
What is the best budget dehumidifier?
Mumsnetters love the Pro Breeze Dehumidifier 1500ml. Lightweight and extremely quiet, you won’t even know it’s there. It sucks up an impressive amount of excess moisture too - we think it's amazing value at £60.
