What have some probably did not understand: The radius of the dehumidification is determined by the engine power of the convection of the device.
For all rooms with high humidity, the device is not suitable due to the weak engine. Since dehumidifiers are at least 10 liters daily. Capacity requires the addition, already at 200 and text.
This device has, in my view only a small radius of about 1 m. to the unit for light to moderate moisture.
Who is not sure should only a meter data sheets to measure the degree of humidity.
