Heating expert explains exact dehumidifier you need for cold and warm rooms
You may have heard that dehumidifiers are key when it comes to reducing condensation inside homes - but some work better than others.
During the winter, when temperatures outside are colder, you might notice condensation starts to form on windows. This is because when the warm, moist air inside meets the cold surface, it causes droplets of water to form.
You might be tempted to simply wipe this off and carry on with your day, but leaving condensation to form repeatedly can cause untold damage to your property. If left untreated over a long time period, it can also lead to mould, which could have devastating consequences on your health - such as causing respiratory problems.
There are many ways to prevent this from happening, but one popular way is to use a dehumidifier, which quickly and efficiently draws excess moisture from the air. They can be very cost-efficient to run, but the appliances themselves can be quite expensive - ranging from £40 to £450, depending on its capacity.
With so many different types of dehumidifiers out there claiming to do different things, it can be overwhelming - especially as there are other things you need to take into consideration as well as price. As well as price and capacity, you need to consider what the correct type is for the room you're going to have it on.
Property expert's simple hack to get rid of bedroom window condensation
Luckily, Which? has made it simple for people to know which dehumidifier they should buy. In a recent video uploaded to TikTok, experts explained that if you have a cold room, you need to have a desiccant. They said: "If you want a dehumidifier for a colder space, like a garage, you need the desiccant type which doesn't require warm air."
Desiccant dehumidifiers work better at lower temperatures, and add warmth to the room, as the air is pushed out. In this type of dehumidifier, air is drawn over a filter and passed over an absorbent material called Zeolite. The moisture is then condensed and collected in a tank.
However, if the dehumidifier going to be placed in a warmer room, the experts recommend a refrigerant or compressor, which works differently as it has two coils. One which cools and creates condensation, and a second that warms the dry air back to just above room temperature.
The experts added: "You just need to place it in the centre of your home and keep internal doors open." Although dehumidifiers don't get rid of mould, they are key to helping prevent it - and there are other things you can do too. The experts recommend opening a window straight away if you spot condensation, as it will "let the moisture escape".
Another tip is to dry off any wet bathroom tiles, as well as your bath and shower, with a dry cloth to absorb the moisture that could turn into mould.
