Dehumidifier and Air Cleaner
The Kullhaus alpha Q20L dehumidifier is the device that effectively removes excess moisture from the air while purifying it at the same time. It therefore addresses two common air quality problems inside a room at the same time. Excessive humidity can lead to mould and mould odours, while airborne pollutants such as dust, pollen and pet dander can cause allergies and respiratory problems. The Kullhaus alpha Q20L dehumidifier air purifier addresses these problems by removing moisture from the air, preventing mold growth and reducing the risk of allergies. In addition, it filters the air, trapping tiny suspended particles and improving overall air quality.
The excellent technical dehumidification features, as well as four air purification stages, make the Kullhaus alpha Q20L in our opinion the best dehumidifier air purifier, helping to remove airborne particles such as bacteria, viruses, dust and other allergens.

Low Noise Dehumidifier
Kullhaus alpha Q20L dehumidifier is possibly the QUIETEST 20 liter dehumidifier.
It is not only the low noise levels of the compressor [40/44dBA actual lab tests] that make the Kullhaus alpha Q20L dehumidifier one of the quietest dehumidifiers for 80 sq.m. Equally important is the quality of the plastic parts and the robust construction of the dehumidifier, which eliminate any squeaking or resonance of the plastics during the operation of the device. Kullhaus has incorporated noise-reducing technologies, i.e. insulated compressor compartments, vibration-absorbing materials, and quiet fan blades.

KULLSAVE Energy Saving System
Kullhaus alpha Q20L low energy dehumidifier uses the smart energy saving function. Set the relative humidity you prefer, ideally 50-55%. The dehumidifier will operate for as long as it takes to achieve the goal. When the humidity drops to the desired levels, the compressor will stop, the fan will run for about 3 minutes on the low speed and the Kullhaus alpha Q20L will go to sleep for 17 minutes. After 17 minutes, only the fan will operate for about 2 minutes, in order to check the relative humidity. If the latter has increased by + 3% above the desired level, Kullhaus alpha Q20L will go into the dehumidification mode. Otherwise, the fan will run for about 3 minutes on the low speed and the dehumidifier will go back to sleep for 17 minutes and so on.

Kullhaus alpha Q20L Dehumidifying Capacity
The dehumidification capacity of a dehumidifier is the amount of moisture (in liters) that the appliance can remove from an enclosed space in a 24-hour period. It is important to remember that the performance of a dehumidifier is affected by both the temperature and the humidity level of the room.

Continuous Drainage
Kullhaus alpha Q20L dehumidifier is set to collect water in the water tank.
You can also choose to use Continuous Drainage to automatically drain the collected moisture through a hose or pipe without the need for manual emptying of the water tank. This feature can be particularly useful in areas with high humidity or where the dehumidifier needs to run continuously. To use a dehumidifier with continuous drainage, you will need to connect a 12 mm diameter hose to the dehumidifier's drainage outlet and run it to a nearby drain or other suitable outlet.
