5 Best Conservatory Dehumidifiers of 2025

If you’re constantly battling condensation and damp in the conservatory, this Pro Breeze 20L Dehumidifier is a great machine to add to the ranks.

It can remove 20 litres of moisture per day and has an automatic ‘humidistat’ sensor (like a thermostat, but for humidity). There’s also as an easy-read digital LED display and a large 5.5 litre water-storage tank.

In order to maintain the correct humidity in the home (which should be around 30-50%) you can set the dehumidifier to uphold your desired level (settings available from 30 – 80%).

It has one of the largest extraction rates of all the dehumidifiers featured on this page, removing up to 20 litres of moisture from the air per day. The dehumidifier will switch off automatically if it senses that the water storage tank is full. It can also be connected to a continuous drainage hose if you want to leave it running without worrying about the tank filling up.

Although relatively heavy, there are wheels in place to make this dehumidifier easier to move around. It also has a handle for carrying.

In terms of performance, this dehumidifier can make a visible difference inside the home – reducing condensation on the windows and improving the overall indoor temperature.

The Pro Breeze does have some additional features that other dehumidifiers lack, such as a child lock setting. It also has a sleep timer and laundry-drying mode, as well as lights to indicate the room’s current humidity level.

Overall, it’s one of the best dehumidifiers for your conservatory due to its impressive power and ability to draw plenty of moisture from the room.

If you’re looking for a quiet dehumidifier, the MeacoDry ABC 10L Dehumidifier produces only 35 decibels and has been awarded a ‘Quiet Mark’ certification.

It’s also been recognised as a Which? best buy, which is reassuring in terms of its quality and performance.

With a capacity to remove up to 10 litres of moisture from the air per day, it’s a smaller unit than many of the dehumidifiers on this page. As a result of this, it’s not quite as powerful as some of the bigger machines – but this means it doesn’t use as much energy as them either.

Consuming 160 W, this is one of the best dehumidifiers for your conservatory if you are looking for something that works well without it being overly loud or astronomically expensive to run. You’re looking at a cost of roughly 3.14p per hour.

However, it’s worth pointing out that this dehumidifier is best suited to smaller rooms, not large cavernous ones.

There is a humidistat for controlling the humidity, and a specific laundry setting that will run the dehumidifier for six hours on full power. It can help with drying clothes, as well as reducing condensation and moisture on windows. There’s also a timer function, to give better control over energy usage.

As a light and compact unit, it’s easy to move between rooms. Plus, due to its quietness, it will be a good option if you need to have a dehumidifier in the bedroom too. Whilst the MeacoDry ABC still makes an audible noise (35 dB is roughly equivalent to the sound of someone whispering), it’s a lot more conducive to sleep than some other dehumidifiers.

Offering a good balance between features and price, this EcoAir DC18 Compact Portable Dehumidifier is one of the best dehumidifiers for your conservatory if you’re after value for money.

It has the capacity to draw up to 18 litres of water from the air per day, and has a relatively large 3.5 litre water tank. These are good specs compared to other models in the same price bracket, and it also built-in humidistat to allow the desired humidity level to be maintained.

Not only can this dehumidifier help reduce dampness in conservatories and bathrooms, it can also speed up the process of drying washing inside by removing excess moisture from the air. There’s no specific laundry setting, but there is an optional 2h/4h timer to make it easier to use.

The only issue with this timer is that it might be more useful if there was one longer period available, like eight hours.

Although this dehumidifier is described as portable, it might be larger than you would expect, measuring 22.5 x 49.5 x 35 cm. It does, however have easy-glide caster wheels to help move it across hard floors.

There’s also a washable air filter and choice of two fan speeds to reduce energy consumption.

It’s just about quiet enough to be used at night-time in a bedroom if necessary, producing approximately 45 dB; it shouldn’t be too distracting whilst reading or listening to the radio in the conservatory either. 45 dB is roughly equivalent to the noise of a conversation at home.

Suitable for medium-size rooms, of approximately 10 – 24 m², this Dimplex FTE16 Dehumidifier will effectively keep moisture at bay in the conservatory.

It has a somewhat simpler design than the pricier models on this list, but still works well to limit condensation and damp; it’s capable of extracting up to 16 litres per day.

Whilst a lot of dehumidifiers have a small display screen, the Dimplex FTE16 does not. Instead of being able to see the current humidity, there are numbered settings (1 – 9) that correlate to different humidity levels.

These work as the ‘humidistat’. For example, on setting 6 the dehumidifier will kick in when it senses that humidity is around 40% or more.

Although this may take a little getting used to, the more basic design is likely the reason that this powerful dehumidifier is priced more conservatively than its competitors.

It also doesn’t negatively impact the effectiveness of the dehumidifier itself.

When the 2.3 litre tank is full, the dehumidifier automatically switches off to avoid accidents. There’s a small icon on top of the unit that lights up when the tank is full. It’s also possible to connect a continuous hose to the tank, so that it empties elsewhere.

Considering its price and size, this is one of the best dehumidifiers for your conservatory if you want a relatively large unit on a budget. It achieves a good middle ground between size, performance and price.

When it comes to volume, it should be noted that this dehumidifier is relatively noisy – sufficiently so that it may disrupt sleep.

This large Vonhaus 20L Dehumidifier can help keep the humidity at around 55 – 65% even in a large conservatory.

It’s capable of pulling 20 litres of moisture from the air, in spaces up to 35 m². Plus, thanks to the 4-litre water tank, it doesn’t need emptying too frequently either. There’s also a hose included to allow for continuous drainage, rather than relying on the water tank, if preferred.

Several different features make this humidifier both easy and intuitive to use, with a simple LED display, 24-hour timer and ‘full tank’ warning light. It will also turn off automatically once the tank is full. Furthermore, a ‘child lock’ feature stops the settings from being changed unintentionally.

In terms of performance, this dehumidifier reduces the humidity sufficiently that there is a noticeable increase in the indoor temperature, as well as visibly less condensation on windows. When used on turbo, it can be a useful machine to speed up the process of drying clothes inside; however, this mode can be quite noisy.

Although there is a quiet night mode, it is about the same as having a fan on. Therefore, it’s not too interruptive, but some lighter sleepers may struggle if hoping to use it in the bedroom at night. Nevertheless, for use in the conservatory, it should blend into background noise.
