The ambient humidity can vary a lot, depending on the time of year, high/low indoor temperature, and whether it is day or night. It is thus extremely important to possess parameters by which the humidity can be controlled in production processes which include organic materials. Even small changes in humidity can be decisive for efficiency, and thus production cost levels.

For staff, excessively low humidity means that the normally moist mucous membranes on the lips and in the nose and eyes dry out quickly. Additional consequences include dry skin, dust problems and obnoxious smells, which collectively contribute to increasing the risk of allergy and other complications as well as decreasing working efficiency.
