Excessive humidity in homes not only causes millions in damage but is also unhealthy. Additionally, the damage looks unsightly. The common belief that moisture comes from outside is usually incorrect. In reality, moisture originates inside the house (evaporation, kitchen, bathroom). The use of highly insulating building materials significantly impairs air exchange, which can only be adequately ensured through active ventilation. Therefore, monitoring the indoor climate is essential for healthy living. The MS-10 indicates whether the indoor climate is too dry or too humid - with targeted ventilation or heating, you can create the right living environment.
