my gazebo (15 m²) has always from the beginning of September to May a moisture content of about 70%. to the Reference must I opted for a dehumidifier, which fulfills the purpose for little money and little consumption. After some research I decided for the Einhell LEF. The advantage of a quiet quiet operation, a tank with 2LFassungsvermögen (sufficient for me) and automatic shut-off when the tank is full. Of course, everyone has to decide individually according to his needs and the requirements of the matter. But for me a definite buy recommendation.
