  • Dehumidifiers are there to optimize the climate in a room. If the humidity is too high, mold may form. Dehumidifiers counteract this.
  • Depending on the design of the dehumidifier, the trapped air is stored in a receptacle or other absorbent material in the unit, preventing it from entering the room again.
  • A dehumidifier does not replace the regular airing: Open the window immediately after showering, cooking or drying clothes. In addition, you should bump four times a day.

In 2011, the real estate portal Immowelt led a survey by. The result: 17 percent The surveyed property owners and tenants stated in their living quarters Mold to have. Most often this is to be found in the bathroom, followed by the bedroom.

That mold growth should not be taken lightly seems to be unaware to many. The nasty mushroom can sometimes be serious Consequences for the health consequential damages range from concentration problems and headaches to allergies, asthma and other respiratory illnesses.

When main causes for mold growth apply one too high humidity and wrong ventilation, because mold especially likes to spread out where moist air is deposited on cold surfaces. To remedy this, the purchase of a dehumidifier worthwhile, which helps to improve the indoor climate. Find out more about this topic in our Dehumidifier Test 2018.

1. What is a dehumidifier?

Dehumidifier comparison 2018: dehumidifier

With a so-called hygrometer you can determine the humidity.

On breathing device (in short, too dehumidifiers called) is used, the humidity in a room or container too to reduce, Depending on the design of the dehumidifier, the trapped air is stored in a receptacle or other absorbent material in the unit, preventing it from entering the room again.

Dehumidifiers are always used when a increased mold risk consists. They are used for drying new and old buildings - especially after water damage has occurred (for example for dehumidification after a flood). They are also used in rooms with particularly high amounts of water vapor, for example in swimming pools. And special construction dryers are also indispensable on construction sites: screeds, paints and plasters are usually liquid and wet and have to dry as quickly as possible to make the house or apartment ready for occupancy.

Often, dehumidifiers will too in combination with humidifiers used to provide an optimal indoor climate.

by the way: The ideal room climate consists of two components - on the one hand from the temperaturethat between 18 and 23° C should lie, and on the other from the humiditythat between 40 and 55 percent should be.

In the following Buyer's guide Our Dehumidifier Comparison 2018 will tell you which different types of dehumidifiers are available, how exactly they work and what you should pay attention to when buying them.

2. Which dehumidifier types are there?

Dehumidifiers can be considered in terms of their operation differ. In the following table we summarize three fundamentally different physical methods on which the construction of the devices can be based. So arise three rough categories of dehumidifiers.

Air cooling with water separation

Dehumidifier comparison 2018: 2018

  • is also called condensation drying
  • The humid air is directed by a fan through a cooled heat exchanger
  • the water drains from the cold surface of the heat exchanger and is collected or discharged in a container
  • so-called condenser are especially suitable for private use or for use in the field of building renovation
Absorption of moisture

Dehumidifier comparison 2018: 2018

  • the air to be dried is absorbed by a chemical desiccant
  • The desiccant can absorb water until it is saturated itself
  • after a certain time, the desiccant must be renewed or regenerated - this can be e.g. done by heating
  • so-called absorption dryer (for example, granulate dryers) are particularly suitable for small, enclosed spaces in which the air hardly circulates (such as a car dehumidifier or for the wardrobe)
Adsorption of water vapor

Dehumidifier comparison 2018: 2018

  • the humid air is led by a ventilator over an adsorbent (mostly silica gel)
  • the dehumidified air is then returned to the room heated
  • the adsorbent has to be regenerated after a certain time - this happens e.g. by drying with hot air
  • so-called adsorption They are usually more expensive to purchase and only suitable for home use in special cases - they are used in industry and on construction sites

Most models in our dehumidifier test are condensation dryer, A condensation dryer is always an electric dehumidifier and performs well, especially in continuous operation a good performance. The other commercial dehumidifiers, Absorption or granule driesr, are usually less suitable for permanently dehumidifying rooms.

Here we have again the Advantages and disadvantages of granule dryers summarized:

  • usually cheaper to buy
  • very easy to use
  • work independently of the room temperature
  • work silently
  • only suitable for small, closed rooms
  • lower power than e.g. condensation dryer
  • Desiccant often needs to be renewed or regenerated

3. Purchase criteria for dehumidifier: You must pay attention to this

3.1. room size

Before you decide for your personal dehumidifier test winner, you should first approximate the Size of the room they want to dehumidify.

In the case of a very small, enclosed space, such as a car or a wardrobe, an absorption dryer (for example a dehumidifier with granules) is usually sufficient. For larger rooms (between 20 m² and 50 m²) we recommend a device with condensation technology.

3.2. temperature

When buying a dehumidifier, you should be aware that such a device only within a certain temperature range can be operated reliably. For which temperatures the dehumidifier is suitable, depends strongly on the respective manufacturer and the construction method. For most dehumidifiers, however, the value is between 8° C and 30° C.

Tip: If you are looking for a dehumidifier that works well below 5° C, you should look for a professional Bautrockner look around.

3.3. power

An easy-to-clean dust filter.

Also the dehumidification Your personal dehumidifier test winner plays an important role. It indicates the amount of moisture that can be removed from the ambient air in a given time.

The dehumidification performance of a dehumidifier is in the unit "Liters per day" (l / d) indicated. In most models, the value is usually between 10 and 30 l / d. In addition to the room size, you should also determine the moisture content and then decide on a model that will provide the appropriate performance.

3.4. Size of the water tank

In some room humidification equipment, the condensate is discharged via a hose. Other models have one internal containerin which the liquid is collected and collected. This container must then be emptied from time to time to prevent overflow. How often an emptying is required depends on the Size of the water tank from. So if you plan to use the dehumidifier for a long time and do not feel like constantly emptying the tank, you should opt for a model with a large tank.

Danger: That does not mean that a regular emptying is omitted! If you do not empty the water tank regularly, your dehumidifier can quickly become a humidifier!

3.5. noise

Powerful condenser dryer usually bring more power, but are also much louder than, for example, granular dryer, which usually give no noise of itself. Depending on the location, this can be problematic: if you want to reduce the humidity in the bedroom, you should be aware that dehumidifying is a certain amount of water noise accompanied. At night, the device should be turned off. The average volume of a Kondenstrockners is about 40 to 50 decibels.

What this means konkrekt, is the following table again to illustrate in more detail:

Sound pressure in decibelscomparable to
10 dBrustling leaves, calm breathing
20 dBTicking a wristwatch
30 dBto whisper
40 dBsoft music, close whisper, quiet residential street
50 dBrain
60 dBsewing machine

3.6. Power consumption of the dehumidifiers

Dehumidifier comparison 2018: dehumidifier

Especially in rooms where a lot of water is used, you should ventilate frequently.

Some dehumidifiers work without electricity, but most dehumidifiers will electrical operated. So that you do not fall from the clouds with the receipt of the electricity bill, you should necessarily before the purchase of a Raumentfeuchtungsgeräts over its power consumption inform.

The manufacturers usually give the rated capacity their devices, which is on average between 175 and 670 watts and thus can vary greatly. High-quality models designed for continuous operation usually consume less power - here the average energy consumption is often less than 0.25 kWh.

3.7. special functions

When buying, also consider whether certain special functions used or desired. This could be e.g. The following functions count:

  • humidistat: automatic control of humidity to the desired degree
  • Overflow protection: Device shuts off automatically as soon as the water tank is full
  • Dual counter: Documentation of working hours and power consumption
  • automatic defrost: automatic de-icing of the evaporator in condenser driers (at very low room temperature)
  • double water drainage system: Possibility to drain the condensation both via a hose and via a container

4. Prevent moisture in the apartment - ventilate properly!

Did you know…?

Surprisingly large quantities of water evaporate in your home every day - all by breathing, sweating, cooking, cleaning and washing or drying the laundry. In a multi-person household, this can sometimes be more than a 10-gallon bucket full of water.

In a flyer on the topic Moisture and mold problems in living rooms and bathrooms leads the Stiftung Warentest Some tips on air dehumidification, which can help prevent mold growth.

Especially in rooms where a lot of water is used (eg in the bathroom, in the kitchen or in the laundry room), it is recommended to ventilate regularly, The experts advise: "While showering or cooking, you should keep the connecting door to the apartment closed. Immediately after showering / bathing or cooking (or even during it), it is best to open the window immediately, so that as much moist warm air as possible can escape immediately before condensation condense on cold surfaces. "

It is also recommended four times a day airing perform. Open all the windows and make sure you have a proper one Draft, In most cases, a complete exchange of air can take place within a few minutes.

6. Questions and answers about the subject of dehumidifiers

6.1. How long should you use a dehumidifier?

The Duration of the dehumidification process depends on many factors depending on, among other things, the air temperature, the room size, the humidity and the power of the respective device. So it's very hard to make a blanket statement about how long you should use your dehumidifier. Dehumidification can be completed in several hours, but it can take several days.

6.2. Is it allowed to heat the dehumidified rooms?

The room being dehumidified may be heated at the same time become. However, it must be ensured that the permissible temperature range is not exceeded (see manufacturer's instructions). In addition, the heat source must not be aimed directly at the dehumidifier.

6.3. When is a dehumidifier worthwhile?

Dehumidifier comparison 2018: comparison

The principle of an absorption dryer.

Is the humidity in a room more than 60 to 65 percent, it can lead to waterlogging and mold growth. An indication of this can be so-called "sweaty windows", on the surface of which condenses water from the air. It is often enough to ventilate the rooms regularly. However, it becomes problematic when a room no windows has - here the purchase of a dehumidifier is often unavoidable. This helps to maintain a healthy humidity in between 40 and 60 percent to reach. Meanwhile, there are quite cheap dehumidifiers on the market, which are affordable for everyone.

tip: Humidity can be determined by using a hygrometer determine. Such a device can be purchased quite cheaply today in the hardware store or on the Internet.
