What is the desired humidity level for optimal indoor comfort?

The optimal humidity level for indoor comfort is generally considered to be between 30% and 50%. This range is ideal because it helps to maintain a comfortable environment, reducing the likelihood of mold growth and dust mites while also preventing dryness in the air that can lead to respiratory discomfort or dry skin. Humidity levels within this range support the body’s natural ability to regulate temperature and maintain comfort, making living and working spaces more enjoyable.

When humidity levels drop below 30%, the air can become too dry, which may cause irritation to the respiratory system and skin. On the other hand, levels above 50% can create a humid environment that encourages the growth of allergens, such as mold, and can make the space feel stuffy and uncomfortable. Thus, maintaining humidity within the 30% to 50% range is essential for promoting health, comfort, and overall well-being in indoor spaces.
