What is the desirable range of humidity from a health standpoint?

The desirable range of humidity from a health standpoint falls between 35% and 50% because this level helps to create a comfortable environment for most people. In this range, the air retains sufficient moisture to prevent dryness, which can lead to respiratory issues, skin irritation, and other health concerns. Additionally, proper humidity levels can help mitigate the growth of harmful mold and dust mites, both of which thrive in overly humid conditions.

Maintaining humidity within this range also contributes to better HVAC efficiency and personal comfort, as excessively low humidity can lead to static electricity and dryness, while overly high levels can create a feeling of stuffiness and discomfort. Thus, the 35% to 50% range is considered ideal for promoting overall health and wellness in indoor environments.
