Dehumidification and Humidification

Optimum level (for comfort as well as building quality) is a relative humidity (rf) of 40-70%. Absorb room moisture and drain out the room. Ventilation + heating = dehumidification. The dry air outside will automatically drive away the humid air indoor. Make sure the value of your holiday home and wooden furniture.
