For a compact and lightweight model, the Hysure 700ml Dehumidifier performs fairly well and with minimal noise. However, it's only suitable for small spaces and will not make a significant impact in large rooms.
But even though this model sits right at the lower end of the price scale and only has one fan speed, it does have low running costs, is easy to move around the house, won't take up too much space and even has an automatic shut-off function, meaning it will stop running when the 700ml tank is at full capacity.
If you're thinking of purchasing a dehumidifier for a small room, such as a home office or box room, read our Hysure 700ml Dehumidifier review to find out if this is the best dehumidifier for you.
Although the DeLonghi DEX212F 12L Tasciugo AriaDry Dehumidifier is on the more expensive side, its sleek appearance is matched by its performance when it comes to drying laundry.
Fast, surprisingly quiet and efficient at drying clothes – leaving them feeling softer than when dried on a heated airer – a few downsides are the fact it's on the heavier side and doesn't have a humidity level display like some of the other models.
However, if you live in an apartment meaning your drying options are limited to heated airers or tumble dryers, it's definitely a purchase worth considering.
The EcoAir DD2 simple desiccant dehumidifier is suited to colder spaces and has a powerful yet relatively energy-efficient wattage. With an automatic shut-off, anti-tilt safety function and a continuous drainage outlet it's a good option if you are looking to leave it running in spaces such as garages.
Although it doesn't show humidity readings of the space you use it in, it's nonetheless fast and efficient and light enough to move around if you're struggling with damp in a number of areas.
It's also fairly quiet to run making it suitable to use inside if your property struggles to get warm.
Specifically chosen for testing in the bedroom due to its Quiet Mark rating and sleep function, this dehumidifier was suitably quiet. While initially noisy when starting up, the fan quickly reduces to a low hum, making it easy to fall asleep while it works.
If you're looking for an affordable solution to window condensation in the bedroom, this could be a great option to consider. It also made the room feel warmer and the generous 12L tank capacity meant it was still working when I woke in the morning.
The handy humidity display also meant I could check exactly what it was achieving. For more details on how I found its perfomance, read our MeacoDry ABC 12l Dehumidifier review.

Dehumidifiers are designed to remove excess moisture from the air and to achieve a healthy relatively humidity.
"A dehumidifier removes moisture from the air – excess moisture that you do not want to condense and hang around your home. It helps to ease damp problems, gives you healthier air to breath and can even make your energy use more efficient," says Chris Michael, fco-founder of Meaco
There are two main types of dehumidifier: desiccant and compressor. All the models reviewed here are compressors, other than the dessicant version we tested for colder spaces.
"These types of dehumidifier have a cold-coils system, like a fridge," says Chris Michael. "They have two sets of coils, the first cools to create the condensation, which is collected into the water tank, the second warms the dry air back to just above room temperature. This helps to create the dry air needed to combat condensation, mould and damp problems."
When won't a dehumidifier be suitable?
If your damp issue is the result of bad ventilation and lots of condensation, a dehumidifier can definitely be helped by a dehumidifier. That said, if damp is a persistent issue, caused by other factors concerning the structure of your home, a different and more involved solution is going to be required long term. A dehumidifier will still help the situation but clearly building work to fix the issue will be a better solution. Start by looking at the causes of mould in a house to help you figure out what could be the root of your problem.
