The size of the room is crucial when choosing the right dehumidifier. The larger the room, the higher the dehumidification capacity should be. It is important to consider the room volume (area in square meters x room height). As a rule, manufacturers assume a room height of 2.5 meters for their room size recommendation.

Depending on where (laundry room, cellar, living room) the dehumidifier is used, other criteria are important. If you are considering drying laundry, a dehumidifier with a swing function is suitable. For water damage, an industrial construction dryer is more suitable. A quiet dehumidifier with a night mode is ideal for dehumidifying bedrooms or living rooms. Mobile dehumidifiers are easy to move around on castors.

If the humidity is very high, the dehumidifier should remain switched on all the time if possible. The energy consumption can be controlled if the appliance has a hygrostat. The hygrostat can be used to set the desired target humidity. As soon as this is reached, the appliance switches off automatically.

Depending on the model and intended use, the water collection volume is also decisive.

Commercially available dehumidifiers for private use usually have a dehumidification capacity of max. 20 liters per 24 hours and a water tank capacity of 4-5 liters. Ideally, the dehumidifier has a connection option for a hose to remove the condensation water in drainage mode.

Dehumidifiers with granulate are cheaper to buy, but the ongoing purchase of desiccant must be factored into the overall costs. Compressor dehumidifiers are initially more expensive, as quality has its price. For a dehumidifier to function reliably for several years, it must be equipped with high-quality components. These components are reflected in the price.
