A dehumidifier can significantly reduce moisture problems, condensation, and musty odors, but you need to choose the right model. Not every device is suitable for every room. Below, you can read what to look for before buying a dehumidifier.
Capacity in liters per day
The capacity indicates the maximum amount of moisture a device can remove from the air per day, measured under laboratory conditions (usually at 30 degrees and 80% humidity). In practice, you will often extract less at home because the air is cooler and drier. Therefore, it is better to buy a model with a slightly higher capacity than you think you need at first glance, especially for larger rooms or significant sources of moisture, such as laundry drying indoors.
Type: compressor or desiccant
Compressor dehumidifiers work best at normal room temperatures (about 15 to 30 degrees) and are generally more energy-efficient. Desiccant models also work well at lower temperatures, making them suitable for an unheated garage or shed, but they often consume more power. So, first determine in which room and at what temperature the device will operate.
Noise level
For the bedroom, the noise level is at least as important as the capacity. Look at the number of decibels on the lowest setting and, if available, at a night mode. A device that stays in the utility room during the day can generally be louder than a model standing next to your bed at night.
Water reservoir and drainage
A larger water reservoir means you have to empty it less often, but it also takes up more space. In case of structural moisture problems, continuous drainage via a hose (if the device has that capability) is often more practical, so you don't have to empty it every day.
Humidistat and automatic shut-off
A humidistat allows you to set a desired humidity level, after which the device automatically stops once that level is reached. This is not only convenient, but it also saves energy because the device does not keep running unnecessarily. An automatic shut-off feature when the reservoir is full is also a practical safety function.
Energy consumption
Depending on usage, a dehumidifier can be a noticeable item on your energy bill. Pay attention to the specified wattage and consider how many hours a day you expect to use the device. A model with a humidistat and timer function is often more cost-effective in the long run because it only runs when necessary.
