If the humidity in the living rooms is too high, this can cause massive problems. Healthy sleep does require a certain degree of humidity, but too high a moisture content in the air should always be avoided - whether in the kitchen, in the basement, in the bathroom or in the living room.
There is a choice of different products with which the air can be dehumidified. Electric dehumidifiers, for example, but also those that get by without electricity and only draw moisture out of the air through the granules they contain.

Dehumidifier in the basement, in the living room or in the car are therefore used more and more often and most products actually work perfectly. Dehumidifiers from Aldi or Lidl in the lower price segment can often keep what they promise, just like expensive dehumidifiers from Quigg or other manufacturers.
In the following we take a closer look at the principle of a dehumidifier, in short, a dehumidifier or room dehumidifier in our test. What can the small devices really do? Drying damp walls in the apartment and basement, removing mold? Can they possibly even cool?
Test of dehumidifiers: how do dehumidifiers work?
The optimum room air humidity, just to start with, should ideally be between 45 and 55%. If the humidity is too low, this can lead to dry eyes; if it is too high, the residents find it muggy or oppressive. Mold can form, which in turn is a health hazard.
If the dehumidifier now removes the moisture from the room, the risk of mold formation is reduced. The relative humidity in the room is reduced.
The vast majority of devices that are commercially available, work on the Condensation principle. They suck in the air, heat it up and then cool it down in a flash. This creates condensation, which collects in the dehumidifier in a separate tank.
Depending on the device, the water tank has a volume of 2 to 7 liters. If the device has to be set up in a room with very high humidity, it should also have a sufficiently large tank. If this has to be emptied constantly, that's pretty annoying.
Dehumidifier test: what do I have to consider when buying?
If a Dehumidifier in the basement, but should also be used in the home, the dead weight should not be too high: some devices are equipped with castors on the underside.
Own devices have the option of one external hose to be connected, with which the condensation water can be drained off directly. This can be useful during a vacation, for example.

Dehumidifier without electricity? Are granules an alternative to the electric dehumidifier?
Devices that work completely without electricity can usually not hold more than one liter of water. Electrical devices have a significantly greater power here. They also have larger tanks and, in some cases, a waste water hose with which the condensation water can be drained off directly.
A pair of Dehumidifier without storm - mostly in the form of a pillow - works with granules instead. This soaks up moisture and has to be dried again on the heater or in the micro wool after use. Some Instead, dehumidifiers have a granulate blockthat you always have to buy again because it gradually dissolves itself. You save Storm, but there is regular follow-up costsespecially when the humidity is high.
Cushions with granulate filling are often used as a dehumidifier in the car or in the wardrobe.
Dehumidifiers that do without electricity are more flexible to use and are therefore often used in the garden shed, in the camper or in the author. However, the performance is significantly lower compared to electrical devices. Real Problems with moisture so can only be done with one electric dehumidifier get a grip.
Do dehumidifiers also help against mold?
It is entirely possible, yes, but only if that The cause of the mold growth is in too high a humidity. This works best with the help of electric dehumidifierswhich suck in the air by means of the integrated fan, guide it inside via fins and then drain the resulting condensate into the water tank when the dew point is reached. The dried, heated air is then released back into the environment. The humidity in the room in question is gradually reduced, which means that the warm, humid air no longer condenses on cold objects and mold can form as a result.
Dehumidifier test: can a dehumidifier also cool?
A humidifier cannot cool, after all, it is not an air conditioning system, on the contrary. Rather, a dehumidifier ensures a slight temperature increase of 2-3 degrees in the room in which it is located.
Where do you actually need a dehumidifier? Car dehumidifier
The areas of application of devices that dehumidify the air are diverse. For example, they are often used when it comes to drying new buildings or after water damage or flooding. The use of a dehumidifier also makes sense wherever there is a risk that mold could form due to high humidity. Also for Dehumidify basement or as Reduction when drying clothes many use a dehumidifier.
