To choose the right air moisture collector, also known as a dehumidifier, there are several important factors to consider. Before discussing them, it is important to mention that determining whether you really need a dehumidifier will help weather station hygrometer at home, also known as a weather station, which measures the relative humidity level in the room, temperature, and CO2 content in the air.

So, how to choose a dehumidifier?

Pay attention to the performance of the dehumidifier

Choose a dehumidifier with a capacity that matches, or ideally, slightly exceeds, the size of your room. The capacity of the device is measured in cubic meters or square meters, so we recommend checking the technical characteristics of the device to ensure that the capacity will not be less than the size of your room.

If you choose a slightly more powerful collector, it will do its job faster, and it will also not work at full capacity, which means that the parts will wear out more slowly and the device itself will last longer. Keep in mind that different manufacturers write different suitability criteria, i.e. the square footage of the treated area may vary, and you should take into account how many liters of moisture the dehumidifier collects per day.

Difficulty of cleaning the device

Once you have decided to purchase the device you want, you should pay attention to its maintenance and cleaning. Certain models have a simple cleaning mechanism, while others require more complex procedures.

Choose a quiet dehumidifier

These devices can be noisy, so we recommend choosing a model that will not interfere with your daily life, especially if it will be used in a residential area rather than in an industrial setting. Typically, dehumidifiers with a compressor will operate noisier than those without one.

Energy efficiency

Also, these devices have different energy efficiency, filter system (air cleaning from dust, mold, bacteria and other allergens) and other convenient functionalities, such as automatic shutdown, timers, integrated relative humidity meter, or control via mobile phone. Let's take a look at the types, according to which criteria you can choose the collector that best suits your needs.

Types of moisture collectors

  • Absorption – this type of collector is used in various industrial and everyday applications, it can operate at low temperatures (from +1), so it is useful in basements and other damp cold places where other devices cannot work effectively. Ideal for extremely high humidity and is economical because it does not require heat energy – it absorbs moisture directly onto its surface;
  • Condensation – this type of dehumidifier is usually chosen by those who have humidity problems in apartments or residential buildings. The main difference from the absorption type is that the absorption type can operate at any temperature with practically no change in its performance, while the condensation collector is more dependent on the air temperature, the lower the temperature, the lower the performance (the optimal operating temperature is 15-40oh) but they are effective in cooling and heating rooms, as some can be integrated into an air conditioning system;

These devices are used for different purposes and have different advantages, so their price varies. Naturally, the more functionalities, such as larger collector capacity, filters against pathogens for air purification, etc., the higher the price.

Also, products from well-known brand manufacturers will be more expensive, and less commonly found ultrasonic collectors may require additional equipment, such as a voltage converter or a special water filtration device.

Which dehumidifier should I buy?

Although dehumidifiers are rated by their capacity for a given area, even a less powerful dehumidifier will do the job properly, but it will take longer and use slightly more electricity than a more powerful dehumidifier. However, the relative humidity in a room will change regardless of the capacity of the device, unless it is an industrial room with rapidly changing humidity levels. 

Our most popular, most purchased dehumidifier models by our customers Air dehumidifier - purifier Trotec TTK 27 HEPA (suitable for rooms 15-25m2), Condenser dehumidifier Trotec TTK 70 HEPA (suitable for rooms up to 50m2) and Condensing air dryer Trotec TTK 96 E (suitable for rooms 70-120m2).

If you want to extract moisture faster and avoid carrying dehumidifiers from one room to another, we suggest choosing a more powerful model. All of them also have integrated HEPA filters, which makes them extremely effective at cleaning the air, and they also have integrated temperature and humidity control, so you don't need to buy an additional hygrometer (weather station) to monitor the additional level of relative humidity.

If you have any questions, you can always call our specialists who will advise you on which room dehumidifier will best meet your needs and make the most efficient use of its operational capabilities. At the same time, if you only need this device temporarily, we invite you to rent a dehumidifier.
