How to choose the right dehumidifier
Before you decide to buy a dehumidifier, it is good to know some basic criteria, useful for evaluating the variety of dehumidifiers on the market.
Power Consumption: Probably the most important criterion for choosing a dehumidifier. You should be aware that consuming a dehumidifier with a compressor varies with room temperature and relative humidity at a given time. That is why internationally the consumption of compressor dehumidifiers is measured at a temperature of 27 ° C, with a relative humidity of 60% and is called Rated Power. Looking carefully you will notice that many manufacturers do not list the "actual" consumption of the dehumidifier, but measured in different room conditions. In any case when checking the consumption of a dehumidifier with a compressor make sure that the consumption is listed as Rated Power 27 ° C RH60%.
It is obvious that the lower the consumption the better!
In addition, several brands of dehumidifiers such as Kullhaus have special modes that save energy, significantly helping your pocket. For example, the KULLSAVE smart energy saving function that works as follows:
After adjusting the relative humidity you want, ideally 50-55%, the dehumidifier will work for as long as it takes to achieve the goal. The compressor will then stop, the fan will run for about 3 minutes and the Kullhaus dehumidifier will go to sleep for 17 minutes. In sleep mode [Standby position] the consumption is only about 0.4W!
After 17 minutes, only the fan operates for about 2 minutes. It controls the relative humidity of the room and only if it has increased by + 3% above the desired level, the dehumidifier will enter dehumidification mode. Otherwise, the fan will run for about 3 minutes on the low step and the dehumidifier will go back to sleep for 17 minutes and so on.
Noise (db): Dehumidifiers powered by a compressor (motor) produce a certain level of noise. If you plan to place the dehumidifier in the bedroom (or in an area of the house that you want quiet), it would be good to take a look at the decibels it produces.
Our experience tells us that the noise of the dehumidifier during its operation is an equally important criterion for choosing a dehumidifier. The noise of the dehumidifier is not only the value dB that refers to the technical characteristics: the better the construction of the dehumidifier, the better the compressor, the quieter the operation of the dehumidifier. The higher the quality of the fan that moves the air in the space, the more efficient, but also quieter the operation of the dehumidifier. We recommend that you insist on seeing / hearing the dehumidifier in operation. Be wary of the listed technical characteristics. In any case, be aware that a completely silent operation of the dehumidifier is simply impossible.
Automatic Restart: Useful and functional feature. In the event of a sudden power failure, the dehumidifier stops and returns to its previous function immediately when the power is restored.
Water tank (lt): Each dehumidifier has a water tank (or water tank), where the water from the dehumidification process is "stored". It is detachable and the larger its capacity (in liters), the less times you need to throw away the water that has been collected.
Ionizer: Most dehumidifiers have a built-in ionizer, which injects negative ions into the home atmosphere, fighting odors, dust, allergens and other harmful elements that cause respiratory problems.
Sleep mode: Sleep Mode when turned on offers lower energy consumption, limiting or deactivating the extra functions of a dehumidifier to the absolutely necessary (such as night lighting).
Display: The dedicated display displays information on dehumidifier settings, related levels, and other functions. The easier and simpler the display is, the easier it will be to use the device.
Compressor: Compressor dehumidifiers are the most common type on the market. The compressor essentially causes the "meeting" of cold and hot air inside and through a special process re-injects the air into your space, filtered and without the presence of moisture particles. The operating range of a dehumidifier with a compressor is 5-35 ?. In any case, if the room temperature drops below 15 °, the dehumidification capacity is significantly reduced. So if the area where the dehumidifier will operate has low temperatures, the use of a dehumidifier desiccant technology is necessary.
Zeolite (Desiccant): This is a dehumidification technology based on the use of zeolite [absorbent drying material] and becomes ideal, even necessary, for areas with little or no heating [under 15?].
Drain connection: All Kullhaus dehumidifier models have the possibility of direct connection to the drain using a special drain pipe.
Clothes Dryer: Modern dehumidifiers come with the extremely useful function of drying clothes, which will take you out of trouble and at the same time will be good in your pocket. It is important to always check the nominal consumption of the dehumidifier and whether it has energy reduction functions. The "clothes drying" function is often achieved by using the timer.
Timer: This feature allows you to set the operating time of your dehumidifier for a specific period of time, ranging from a few minutes to up to 24 hours. Space (in square meters): Each dehumidifier can cover a specific area of square meters, so before you reach your choice you must first see the space that will be called to cover. A defining element that determines the square meters that a dehumidifier can cover is the air flow, which is measured in cubic meters per hour m3 / h.
