Relative humidity levels indoors should be maintained within which range?

Maintaining indoor relative humidity levels within the range of 20-60% is essential for both comfort and health. This range helps to reduce the risk of mold growth and dust mites, which thrive in high humidity environments. It also minimizes the chances of respiratory issues and promotes overall well-being by preventing overly dry air, which can lead to dry skin, irritations, and respiratory discomfort.

Furthermore, this humidity range aids in the preservation of building materials and furniture, reducing the likelihood of damage due to moisture or excessive dryness. Keeping humidity levels within this range is important in healthcare settings as well, where stable environmental conditions can significantly impact patient outcomes and the performance of patients' respiratory systems. Proper humidity control can enhance air quality and create a more conducive environment for both staff and patients.
