Why is controlling indoor humidity important?

Controlling indoor humidity is essential because it directly influences airborne moisture levels, which can impact health, comfort, and structural integrity. High humidity can create an environment conducive to mold growth, which poses health risks such as allergies and respiratory issues. By maintaining optimal humidity levels—ideally between 30% and 50%—the risk of mold proliferation significantly decreases.

Additionally, a balanced humidity level contributes to a more comfortable living environment by preventing the air from feeling muggy or overly dry, which can lead to discomfort. This is why focusing on promoting comfort and reducing mold growth risks makes controlling indoor humidity vital for overall well-being. While other options may touch on important aspects related to building maintenance and occupant satisfaction, the primary concern of reducing mold growth and ensuring comfort provides a clear context for the importance of humidity control.
