Having a Relative Humidity level too high is the cause of many problems in our daily life. From raw materials, production, packaging through transport and storage. All products and buildings are affected by high relative humidity. By controlling this the product's lifetime and quality can be improved. 
Even small changes in relative humidity can generate mould. Increased mould is often caused by other moisture related problems such as condensation or ice. There are many kinds of mould and they grow at different humidity levels, but once conditions reach 70% there is a rapid increase in growth. Mould and fungus are present in almost all materials. They can survive without moisture, remaining dormant for decades, even centuries. Munters dehumidifiers can maintain conditions so that mould related problems are eliminated.
