Question: 1 / 400

What is the significance of indoor relative humidity levels?

High humidity is always beneficial for comfort

Appropriate humidity levels (30-50%) are essential for comfort and preventing mold growth

The significance of indoor relative humidity levels lies primarily in maintaining appropriate levels for comfort and health. Keeping humidity levels between 30% and 50% is crucial because it supports a comfortable indoor environment, reducing feelings of stuffiness or dryness that can occur at extreme levels. This range helps to prevent problems related to excess moisture, such as mold growth, which thrives in overly humid conditions, as well as condensation on surfaces that can damage building materials and furnishings.

Inadequate humidity can also lead to discomfort, as the skin may feel dry, and respiratory issues can be exacerbated when air is too dry. Therefore, maintaining humidity within the ideal range is fundamental for both occupant comfort and overall indoor air quality.
