A dehumidifier can also save you money on invoices, so it is an investment.

But which dehumidifier is best for you? Unless you are a humidity expert, dehumidifiers all look alike. It is difficult to know which dehumidifier is right for you and your house without having all the relevant information. This is why we are here to help with certain dehumidifier facts and an overview of the best models you can buy.

What is a dehumidifier?

A dehumidifier is a unit in the corner of the room and sucks air humidity. This means a cleaner and healthier air. Simply adjust the humidity level you want and let the machine do its thing. The humidity recommended in your home is between 40% and 60% during the summer months and between 30% and 50% when it becomes colder. Anything above 60%, then wet conditions can cause humidity, condensation, mold and bacteria. This is particularly problematic for people with asthma and allergy, as mold can cause respiratory problems. Carpets in wet environments can also keep humidity and attract mites.

How do dehumidifiers work?

There are two main types of dehumidifiers:

Refrigerant dehumidifiers – also known as compressors, they use a cold coil that draws air condensation when it comes into contact with the reel surface. This condensation then flows into a tank (which can vary in capacity).

Dehumidifiers Dessic – These pass the air on a wheel covered with a water absorption material known as the desicant (a bit like the operation of a sponge). The desiccant is regenerated by an internal radiator, so humidity flows into the tank. Designing dehumidifiers can release heat – which makes them ideal for unheated parts – while refrigerant dehumidifiers fight at cooler temperatures.

How much water does a dehumidifier collect?

Dehumidifiers are generally listed by their humidity collection quota per day, from 10 liters to more than 20 liters every 24 hours. It should be noted that some models are announced according to performance in countries with more humidity than the United Kingdom, and it is unlikely that you really collect 25 liters each day. Remember that dehumidifiers have a maximum capacity of the water tank, generally between 1 and 4 liters. So, even if you collect liters on liters of air water, the tank should be regularly emptied. Unless your dehumidifier has a continuous drainage function, in which case you can attach a pipe to the ring of the unit to a drain.

Where should you put a dehumidifier?

The obvious answer is to put the dehumidifier in the rooms with a wet problem. Also close the windows and doors. If it is a bathroom, put the dehumidifier outside the door and let the unit suck the humidity of the room.

Can dehumidifiers dry clothes?

In winter, the use of a dehumidifier for drying clothes changes the situation. It saves laundromat trips or the cost of managing your own dryer – and prevents you from stuffing your radiator with wet clothes. In addition, wet clothes draped around your house will only add humidity to the air. For best results, hang your washing on a rack alongside your dehumidifier in a small room. The dehumidifier will pull the humidity of your clothes so that they dry faster.

Do dehumidifiers use a lot of electricity?

In addition to saving on washbasin costs, a dehumidifier will save money on heating bills because less humidity means less shiver biting in the air. You can also save money on products to move molds or odors. And this dryer you thought you were buying? Forget that. A dehumidifier will cost you much cheaper. In general, a portable dehumidifier will consume between 30 and 50 watts per hour.
