The best dehumidifiers in the test comparison 2021

Dehumidifiers – the most important things in a nutshell

When deciding on an air dryer, the following factors are important:

Dehumidification performance: When choosing a dehumidifier, it is important that users compare the performance of the model with the room size in which it is to be used. A compact device is suitable, for example, for a small bathroom without a window. When used as a construction dryer or when there is high humidity, such as in old cellars, users should opt for a strong model. How it works: What mechanism do air dehumidifiers work? Electric dehumidifiers work through condensation, while mobile ones work without electricity, e.g. B. with granules and are suitable for small spaces. Since electric dehumidifiers are more powerful and are sometimes even suitable as construction dryers, we have only included these variants in our comparison. Price: Cheap electric dehumidifiers are available from 40 euros. However, high-priced models can also cost over 300 euros. In our dehumidifier test comparison, the prices are between about 40 and 200 euros. (As of: 06/2021)

The best dehumidifiers in the test check and comparison

In our short dehumidifier check, we reveal who our recommendations are best for and what distinguishes the models.

Comfee MDDN-10DEN7 dehumidifier – recommendation for normal sized rooms

If you are looking for a dehumidifier, you cannot ignore the manufacturer Comfee. Our recommendation Comfee MDDN-10EN7 is one of the most popular models. The device is particularly suitable for normal sized rooms. Most of the similarity is in our comparison to the Pro Breeze dehumidifier, as the water tanks hold 2 or 1.8 liters and the dehumidification performance within a day is 10 or 12 liters. The easy-to-read LED display, the use of an environmentally friendly refrigerant and a practical handle round off the benefits.

LONOVE dehumidifier – recommendation for small rooms and bargain hunters

We recommend the LONOVE dehumidifier for small rooms, in our dehumidifier test comparison it is the most compact model. The water tank only offers space for one liter and within a day it collects almost half a liter of moisture. However, it is ideal for preventing mold in small bathrooms, for example. At around 40 euros, it is also the cheapest device in our dehumidifier test comparison. (As of: 06/2021)

The best dehumidifiers in comparison – the technical data

In our dehumidifier test comparison, the models differ particularly in their dehumidification performance. Aktobis WDH-520EB is very strong with 25 liters in 24 hours. For simple use for mold prevention, we recommend the devices from Comfee and Pro Breeze, which collect between 10 and 12 liters within a day and thus greatly minimize the humidity. For small rooms we recommend the LONOVE dehumidifier, which provides 0.45 liters of dehumidification performance in 24 hours. We have summarized further similarities but also differences in the table with the technical data.

Purchase advice for dehumidifiers – the most important criteria when buying

Our purchase advice shows what is important when buying a dehumidifier:

Suitable room size: It is important to specify it in square or cubic meters. This must match the room in which the device is to be installed. For a bathroom with a few square meters and without a window, a smaller device is often sufficient. A more powerful dehumidifier should be used in an open and spacious living space.

Dehumidification performance: How much condensate can an electric dehumidifier remove from the room air in one day? A small device like the LONOVE dehumidifier collects a little less than half a liter of condensate within a day. A medium-strength device like the Pro Breeze removes 12 liters from the air. In our test comparison, the Aktobis model even manages 25 liters within 24 hours. Larger devices are also suitable as construction dryers.

Water tank and hose connection: how big is the water tank? Is the container removable? Is there an overflow warning or is there even an integrated automatic switch-off? Does the dehumidifier have a connection for a drain hose? Larger water containers have a capacity of 5 liters. In our dehumidifier test comparison, this is the case with the Aktobis dehumidifier. A lower capacity counts around one liter. That applies e.g. B. on the compact LONOVE dehumidifier in our comparison. An optional hose is useful when the dehumidifier has to be in constant use. A drain hose is particularly useful when used as a construction dryer. For small interiors, however, a room dehumidifier without an additional drain hose is completely sufficient.

Operating volume: Loud noises can be annoying, especially in continuous operation. To avoid personal annoyance, users should pay attention to the decibel rating of the dehumidifier. A high level of performance is usually noticeable with distinctive operating noises. Moderate is a volume that is within the scope of the room volume of 30-40 decibels. In our dehumidifier test comparison, the devices come to a working volume between 35 and 45 decibels. Values ​​below 50 decibels are still considered pleasant.

Comfee MDDN-10DEN7 dehumidifier – recommendation for normal sized rooms

The Comfee MDDN-10DEN7 dehumidifier is the right device for users who want to improve the air quality of medium-sized rooms. The water tank holds 2 liters and in continuous use the dehumidification capacity is 10 liters within 24 hours. Users should keep in mind that in this case it is necessary to change the water tank frequently. However, the water tank is easy to remove and the water level indicator makes it easier to keep an overview. Unfortunately, there is no drainage hose. In natural use, for example in the living room or bedroom, we rate this as a minor weak point. A drain hose only becomes a necessary extra for a dehumidifier when it is used as a construction dryer or after water damage.

The LED display allows easy operation at the push of a button, and the humidity values ​​can be viewed in real time. A handle enables flexible use, so that the approximately eleven kilograms heavy dehumidifier can be transported to different areas of use without any problems. The environmentally friendly R290 refrigerant is used for cooling during air dehumidification.

We recommend Comfee MDDN-10DEN7 to everyone who wants to regulate their humidity in normal rooms to good values ​​in everyday life. Plus points are the quickly exchangeable water tank, the modern design and z. B. the auto function, so that the air purifier automatically continues to work in the set programs after a power failure. If the corner criteria of the presented Comfee air purifier are too low for you, you should take a closer look when buying. Alternatively, this model is also available with more power and larger water tanks.

Comfee Dehumidifiers – Important Tests and Ratings

Customers on Amazon rated the Comfee MDDN-10DNE7 dehumidifier with an average of 4.5 out of 5 stars. (Status: 06/2021) In the dehumidifier test or comparison by computerbild.de, Comfee MDDN-10DEN7 emerged as the price-performance winner. (Status: no date) The experts from Öko-Test have not yet tested Comfee MDN-10EN7 and so far only had another model of the brand in the test in October 2018. (As of: 06/2021)

Pro Breeze dehumidifier – recommendation for superior dehumidification performance

The Pro Breeze dehumidifier is most similar to the Comfee model in our test comparison. The water tank is of a similar size and the dehumidification performance is almost identical. The water tank holds 1.8 liters and the dehumidification capacity is 12 liters within 24 hours. We rate this as okay and suitable for medium-sized rooms. The advantage over Comfee in the case of continuous use: Thanks to a drain hose, there is no need to change the water tank frequently and the water can drain continuously. This is particularly practical when the Pro Breeze dehumidifier is used as a construction dryer.

In addition, an ideal place for the Pro Breeze dehumidifier is, for example, a basement room, living room or bathroom. In these cases, the drain hose is not absolutely necessary. Thanks to a humidity sensor, Pro Breeze switches itself off automatically as soon as the desired humidity value is reached. This saves energy and the device only runs as long as necessary.

Users make the right choice with Pro Breeze if they are looking for a flexible model with superior dehumidification performance. The castors allow a quick mobile change from room to room and the variance between the water tank or the drain hose allows it to be used as a conventional dehumidifier in the apartment or as a construction dryer or model for damp cellars. Settings can easily be made via the LED display, with three dehumidification modes to choose from: auto, continuous and sleep.

Pro Breeze Dehumidifiers – Important Tests and Ratings

Amazon customers rated the Pro Breeze dehumidifier with a very good 4.5 stars out of a total of 5. (Status: 06/2021) In the dehumidifier test and comparison by the editors of computerbild.de, the experts counted the Pro Breeze model among the top devices. (Status: without date) Unfortunately, we currently have no further Pro Breeze tests or evaluations from, for example, the Stiftung Warentest. (As of: 06/2021)

Aktobis WDH-520EB dehumidifier – recommendation for large rooms & after water damage

In our dehumidifier test comparison Aktobis WDH-520EB is the most powerful model. The water tank has a capacity of 5 liters and in continuous use within one day it achieves a dehumidification performance of up to 25 liters per day. The manufacturer recommends use in rooms that are up to 50 square meters in size.

The Aktobis dehumidifier has a display that shows the current humidity and provides a status overview. The dehumidifier switches off automatically when the target value has been reached and switches on again as soon as the room becomes more humid. We rate this as efficient, as the device only uses electricity when it is needed. At 13 kilos, it is also the heaviest model in our comparison. Practical: castors and handle make transport easier.

We recommend the Aktobis WDH-520EB dehumidifier for large rooms or after water damage, when continuous use is necessary. Frequent changing of the water tank is less necessary with a 5 liter capacity than with the Comfee or Pro Breeze model from our comparison, which absorb around 2 liters of condensed water. If that is not enough at Aktobis, users can also connect a drain hose so that the water can drain off directly. But be careful: This is not included in the scope of delivery and must be purchased separately.

Aktobis dehumidifier – important tests and ratings

Amazon customers rated the Aktobis dehumidifier with an average of 4.5 stars out of a total of 5. (Status: 06/2021) The Aktobis dehumidifier WDH-520EB is listed among the best models in the dehumidifier test or comparison by computerbild.de.

LONOVE dehumidifier – recommendation for small rooms and bargain hunters

If you want to avoid mold growth in your home, it doesn't always have to be heavy equipment. More compact dehumidifiers are also suitable for small rooms. We recommend the LONOVE dehumidifier for these uses. In our dehumidifier test comparison, it is therefore also the smallest model and weighs only 1.2 kilos. For comparison: the other recommendations weigh between 10 and 14 kilos. The water tank holds up to one liter of condensate and within one day the dehumidification capacity is 450 milliliters per day.

An ideal location for the mini dehumidifier from LONOVE is, for example, a small bathroom, especially if there is no window and the humidity therefore rises quickly. Since the dehumidifier is only 35 decibels loud, it is also suitable for the bedroom or office without being a nuisance. As soon as the water tank is full, the LONOVE dehumidifier switches off automatically.

The LONOVE dehumidifier is best suited for small rooms. It is unsuitable as a construction dryer. The water tank and the dehumidification capacity of almost half a liter within a day are simply too low for this. However, we do not rate this as a disadvantage, as that is not the purpose of a mini dehumidifier. At 40 euros, it is also the cheapest model in our test comparison. (As of: 06/2021)

LONOVE dehumidifier – important tests and ratings

Amazon customers rated the LONOVE dehumidifier with an average of 4 out of a total of 5 stars. (Status: 06/2021) We currently have no further evaluations or tests on the LONOVE dehumidifier. (As of: 06/2021)

What are the best dehumidifiers?

We recommend the following models in our dehumidifier test comparison:

What does a dehumidifier cost?

The costs for an electric dehumidifier can vary greatly depending on the drying performance for rooms of different sizes. Cheap models are already available for 40 euros. High-priced devices, for example from De'Longhi, cost more than 300 euros. Our recommendations are in the price range from 40 to 200 euros. (As of: 06/2021)

What is a dehumidifier?

Dehumidifiers are devices that reduce the absolute humidity in rooms. They are suitable for the prevention of mold or after water damage or during construction. There are electrical versions or cordless dehumidifiers that extract water from the air through granules.

Why do you need a dehumidifier?

Better safe than sorry. This also applies to the prevention of mold. Where tips such as regular ventilation are not sufficient, users should consider purchasing a dehumidifier. The perfect humidity is between 40 and 60 percent. In the event of water damage, for example due to a broken pipe, certain dehumidifiers are also suitable. Some models are even suitable as construction dryers.

What are the advantages of dehumidifiers?

Dehumidifiers offer the following advantages:

Reduction of humidityImproves the indoor climateMold is prevented preventivelyIn the event of water damage, rapid drying, reduction in humiditySuitable models for certain room sizesSupports the effect of ventilationCertain models can also be used with a drain hoseEasy to useFlexible in use

What are the disadvantages of dehumidifiers?

However, in addition to the advantages of dehumidifiers, there are also a few disadvantages:

Desired humidity often cannot be set Power consumption can be high Operation can be noisy

How does a dehumidifier work?

The functionality of an electric dehumidifier is already in the name. The device takes in air and dehumidifies it. A cooled evaporator causes the water to condense and then it is led into a collecting container or via a drain. The dehumidified and cooled air is then reheated and released into the room. This process is repeated until the air in the room has reached the desired humidity. If a hygrostat is integrated, the device switches itself off automatically at this point.

There are also dehumidifiers without electricity. This variant works with the help of granules that reduce the humidity. However, these mobile and usually cheaper models than their electric versions are only suitable for small spaces and are less effective. But they are energy-saving and more environmentally friendly.

Which brands offer dehumidifiers?

Popular brands of dehumidifiers include:

ComfeeSUNTECAktobisDeLonghiPro BreezeTrotecSyntroxComedesDe´LonghiKlarstein

When is a dehumidifier useful?

A dehumidifier is particularly suitable when the humidity in rooms is over 65 percent. Dehumidifiers support the effect of regular ventilation and offer a high level of protection against mold growth.

A dehumidifier is not only useful as a preventive measure, but also in an emergency, after a pipe burst or other water damage, so that the rooms can be dried again quickly. Another popular application is laundry basements in which clothes are hung up to dry after the wash cycle.

Is a dehumidifier harmful?

No, using a dehumidifier is not harmful. Some work with desiccants or granules, such as calcium chloride. However, this is not released into the environment via gas during operation. However, users should avoid direct contact with the skin or eyes, as it can cause irritation. However, if dehumidifiers are used as recommended, their use is not harmful or toxic. Dehumidifiers rather have the purpose of reducing the harmfulness. For example, by preventing the formation of mold and thus avoiding possible damage to the respiratory tract.

What are small dehumidifiers good for?

One factor that we also mention in purchasing advice is the size of the room. A dehumidifier should always be purchased according to the size of the room. A small dehumidifier is therefore not suitable for large rooms, but is completely sufficient in a small, windowless bathroom. Mini dehumidifiers are good if they are used appropriately. So building dryers or for continuous use, they do too little dehumidification work.

Where is the best place to set up a dehumidifier?

The ideal location for a dehumidifier is in the middle of the room where the humidity in the air is to be reduced. The environment should be as free of barriers as possible so that the air can be taken in and dehumidified simply and easily. This means that users should not deliver the dehumidifier with furniture or decorative items.

What is the difference between air purifiers and dehumidifiers?

At first glance, dehumidifiers and air purifiers may look similar. Both are also useful for improving air quality. Nevertheless, they can complement each other, but are different in their application:

Air purifier: Free the air from pollen, fine dust and other pollutants. The way it works is based on an efficient filter performance that also removes allergens and viruses from the air. That is why air purifiers are synonymous with air washers and they clean the air. Air dehumidifiers: If the humidity is too high, above 60 percent, the risk of mold increases and the risk of residents becoming ill or developing allergies. To avoid mold, dehumidifiers or dryers ensure better moisture values. For example, the air is not stuffy. Places of application include Baths or cellars. In an emergency, dehumidifiers are also suitable for pipe damage. Strong models can be used as construction dryers.
